The only pollinator we observed was Trigona, a ubiquitous pollen‐collecting tropical bee that visits many species opportunistically (Roubik, 1989) and was seen visiting flowers of T. chantrieri at one of our field sites. A multi‐year study of factors affecting fruit production in Aristolochia paucinervis (Aristolochiaceae).

Nome botanico: Tacca chantrieri. 4.0.4, SAS Institute, 2002) with both population and pollination treatment as fixed effects. To determine if changes in flower position promoted self‐pollination, we counted pollen grains on the stigma at three time periods: (1) 0630 hours, 4 h before flower opening; (2) 1030 hours, right after flower opening; (3) 2230 hours, 12 h after flower opening at which time flowers were pendant. P REDICTING MATING PATTERNS FROM POLLINATION SYNDROMES: THE CASE OF ‘‘ SAPROMYIOPHILY ’’ IN T ACCA CHANTRIERI (T ACCACEAE) 1 L ING Z HANG, 2 S PENCER C. H.

To date, very limited publication on T. chantrieri are available. Ancestral reconstruction of flower morphology and pollination systems in Schizanthus (Solanaceae). B, Tacca chantrieri manifests many floral traits corresponding to fly pollination, yet it has a high selfing rate, likely corresponding to delayed selfing, when the flower inverts and the pollen spills onto the stigma (photo courtesy of Q.-J. T. chantrieri is an understory plant and requires high humidity. Published by the Botanical Society of America continuously since 1914, the American Journal of Botany (AJB) is the Society’s flagship research journal. and Tacca chantrieri André, demonstrate a very high degree of geograph- ical population stratification, consistent with a hypothesis of self-pollination (Zhang et al. The Black Bat Plant is a very unusual plant from the yam family (Dioscoreaceae), grown for it’s bizarre flowers. chantrieri can be found growing in the understorey of natural forests in the humid tropical regions of Southeast Asia (Zhang et al., 2005). . 2e). Future studies in pollination biology might consider the measurement of mating parameters to determine if the considerable investment that occurs in display traits is indeed repaid through the benefits of outcrossing. Access supplemental materials and multimedia. We constrained pollen and ovule allele frequencies to be equal to each other to maximize the accuracy of the mating system estimates. Plants at WEV produced 7–20 (13.2 ± 0.5, N = 50) flowers per inflorescence. The populations were located in a relatively restricted portion of the geographical range of T. chantrieri (Fig. We randomly selected 30 inflorescences, one per plant, and recorded the total number of flowers, the duration of flowering, the number of filiform bracteoles, and for one flower per inflorescence, we estimated the number of pollen grains and ovules. Tacca, a genus of tropical herbs, possesses near black flowers, conspicuous involucral bracts and whisker‐like filiform bracteoles. The moist forest habitats of T. chantrieri are characterized by deep shade, and despite the general abundance of flies in tropical regions, these particular environments may not favor predictable pollinator service. We have provided several hypotheses that might explain the association between high selfing and the sapromyiophilous syndrome in populations of T. chantrieri in SW China. Tacca Chantrieri rare batman type of flower bulb 1 bulb pack affordable prices, quality product , well hydrated bulb available at www.seedsnpots.com Its wing-like bracts are a deep purple and have the appearance of bat wings. View picture of Tacca Species, Bat Flower, Cat's Whiskers, Devil Flower (Tacca chantrieri) at Dave's Garden. We investigated pollination and mating in Tacca chantrieri populations from SW China to evaluate this assumption. In Yunnan Province, SW China, the region in which our studies were conducted, the species flowers from April to July. The … For this treatment, not all flowers within an inflorescence were cross‐pollinated because of the technical difficulties associated with bud emasculation in this species. Finally, we estimated mating patterns (see later) in four populations occurring at the following locations: Bubeng dipterocarp forest (Shorea wangtianshunea, Dipterocarpaceae) in Mengla County (BB); Wild Elephant Valley in Jinghong County (WEV); Menglun nature reserve in Mengla County (ML); protected forest close to the Mengyang‐Menglun highway (MY), 43 km from Mengyang in Jinghong County (Fig. Fioritura: (Aprile – Agosto).Fiori di color viola-nero. An alternative possibility is that the bracts and bracteoles function in seed dispersal and serve to attract dispersal agents to plants. Our results indicate that despite considerable investment in extravagant display, populations of T. chantrieri are highly selfing. We confirmed with SEM images that pollen grains are deposited on the bodies of Trigona (Fig. Tacca, a genus of tropical herbs, possesses near black flowers, conspicuous involucral bracts and whisker‐like filiform bracteoles. 1). Pipistrello NERO FIORE-tacca chantrieri-semi-quantitativi di selezione. Despite the presence of numerous potential pollinators, only a handful of small, stingless bees paid any attention to these obvious floral cues. Breeding Systems and Population Genetic Structure Monocotyledons: systematic and evolution, part 1. The only genuine pollinators that we observed in either population were stingless bees (Trigona sp.) When flowers were emasculated just before opening, they produced 42.3% ± 4.1 fruit set and 28.4% ± 3.24 seed set. This led the authors to suggest that most bat plants are self-pollinated. Tacca chantrieri, pronounced as TA-ka CHAN-tree-ay-ree, is a rare plant, also known by the names, ‘devil’s tongue’ and ‘bat plant’, due to its unusual maroon foliage with green bracts, which are said to resemble whiskers or wings. Latin chantrieri, after Chantrier Frères, nurserymen of Mortefontaine, France. Floral Visitation, Pollen Removal, and Pollen Transport of In a consistently pollinator‐limited environment, floral adaptations promoting autonomous selfing could have been selected, thus explaining several features of the floral biology of the populations we investigated. Tacca is primarily Palaeotropical in distribution, centered in Indomalesia, China, and Southeast Asia (Drenth, 1972). Overall visitation rates of Trigona at WEV were 0.93 ± 0.22 (range 0.43–1.53, N = 6) visits/flower/h. and you may need to create a new Wiley Online Library account. With little doubt, as described by Drenth (1972) and Saw (1993), species of Tacca, including T. chantrieri, possess a suite of traits normally associated with sapromyiophily. Another unexpected surprise regarding Tacca chantrieri is its capability of self-pollination despite the fact that in nature they look like being pollinated by flies. Temperatura ottimale: tra i 28°C e 29°C. Pollinator visitation was infrequent and bagged flowers set abundant seed. Contrary to this expectation, populations were highly selfing. TACCA CHANTRIERI 'NIVEA' SEEDS (White bat flower) - Plant World Seeds. We made preliminary phenological observations in natural populations and monitored in detail flowering and fruiting on transplants obtained from the Menglun population during 2001–2003. The three treatments were: (1) an unmanipulated control, (2) the removal of bracts and bracteoles, and (3) staked inflorescence. 3, p. 517-524. Trova tacca chantrieri in vendita tra una vasta selezione di Piante, semi e bulbi su eBay. Our online platform, Wiley Online Library (wileyonlinelibrary.com) is one of the world’s most extensive multidisciplinary collections of online resources, covering life, health, social and physical sciences, and humanities. The flowers are somewhat bat-shaped, are up to 12 inches across, and have long 'whiskers' that can grow up to 28 inches. 2f). Rara in Italia, la tacca, anche chiamata "pianta pipistrello", è originaria delle foreste tropicali del sud-est asiatico e dell'Africa. Pollination syndromes and floral specialization. Therefore, we have no information on whether our manipulations influenced pollinators in any way. It is distinguished by the following characters: the petioles, peduncles, and flowers are red wine coloured instead of dark purple; the bracts are very similar to T. chantrieri, but the fruits have different intumescent placentas, which fill the fruit cavity; and the … 1 These features have been assumed to function as a “deceit syndrome” in which reproductive structures resemble … Tacca Nivea: Family: Taccaceae Origin: Malaysia . +EUR 9,00 di spedizione. In areas where T. chantrieri occurs, local inhabitants liken the appearance of the species to a flying bat, a sinister face, or a mean tiger with whiskers. Plants are 50–100 cm tall with tubers or creeping rhizomes and alternate, elliptic, entire leaves. Read your article online and download the PDF from your email or your account. For treatment (2), we bagged inflorescences on each individual prior to anthesis to prevent access by pollinators. Tacca chantrieri has extravagant floral displays and a high investment in reproductive structures that lead to the expectation that it is largely outcrossing (Drenth, 1972; Saw, 1993). These features have been assumed to function as a "deceit syndrome" in which reproductive structures resemble decaying organic material attracting flies that facilitate cross-pollination (sapromyiophily). that is dominated by Tetrameles nudiflora (Datiscaceae) and Horsfieldia tetratepala (Myristicaceae). For example, the loss of bracts, and to a lesser extent bracteoles, would involve significant re‐modeling of plant phenotype and the persistence of these traits may reflect structural constraints to such fundamental changes in morphology. During flowering, the most conspicuous features of display in T. chantrieri are the large, purple involucral bracts and long, filiform bracteoles (Fig. II. We propose several explanations that help to resolve this paradox. Gels were stained for enzyme activity following recipes in Wendel and Weeden (1991). However, when fruits were mature 4 mo later, samples sizes were reduced because of damage by elephant trampling. The extracts were adsorbed onto chromatography‐paper wicks (Whatman's 17 wicks, Maidstone, UK), and placed directly onto 12% starch gels (1 : 2, hydrolyzed potato starch, S‐5651 [Sigma, Missouri, USA] and CAT 32823 [USB Corporation Ohio, USA]). Shift towards autogamy in the extremely narrow endemic Aquilegia paui and comparison with its widespread close relative A. vulgaris (Ranunculaceae). If you do not receive an email within 10 minutes, your email address may not be registered, The Black bat flower, Tacca chantrieri, is a species of flowering plant in the yam family Dioscoreaceae. 3. Assessing the impact of pollinator and disperser disruption on plant extinction. Inbreeding depression and its evolutionary consequences. (b) The inflorescence display with prominent, dark purple bracts and whisker‐like bracteoles. Evolutionary mechanisms in pollination biology. Tacca chantrieri Synonyms: Bat Flower, Cat’s Whiskers, Devil Flower, Tacca integrifolia chantreieri. The autonomous selfing mechanisms and low pollen : ovule ratio of T. chantrieri are certainly consistent with this scenario; however, the sub‐maximal fruit set that we recorded in open‐pollinated and bagged flowers are not expected in populations with a long history of selfing. Contrary to this expectation, populations were … We propose several hypotheses to resolve this paradox and argue that future studies of pollination syndromes would benefit by investigation of both pollination and mating biology. Tacca integrifolia flowers are presumed to be pollinated by flies. Tacca khanhhoaensis V.S. Despite the possession of traits commonly associated with fly pollination by deceit, we recorded no flies acting as pollinators of T. chantrieri. These features have been assumed to function as a "deceit syndrome" in which reproductive structures resemble decaying organic material attracting flies that facilitate cross-pollination (sapromyiophily). — A: Flower. Previous workers have assumed that these structures function to attract flies to plants in the shaded understory of tropical forests. Pollen‐ovule ratios a conservative indicator of breeding systems in flowering plants. Unfortunately, a rigorous cost‐benefit analysis of the balance between selfing and outcrossing in plants has yet to be undertaken (see Eckert and Herlihy, 2005). Pollen loads on stigmas indicated autonomous self-pollination, some of which occurred prior to flower opening. Tacca chantrieri has extravagant floral displays and a high investment in reproductive structures that lead to the expectation that it is largely outcrossing (Drenth, 1972; Saw, 1993). . The seed set of inflorescences with bracts and bracteoles removed was not significantly different from unmanipulated inflorescences, suggesting that these structures play a limited role in pollinator attraction, at least at our study sites. Amots Dafni, W. John Kress, Jeff Ollerton, and Shuang‐Quan Huang for constructive discussions and comments on the manuscript; Mr. Neil White for assistance with allozyme analysis; Mr. Xiao‐Dong Yang and Pan‐Yu Ren for some art work on photographs; Dr. L. G. Saw for providing his reference on Tacca, and Dr. S.‐Q. Adaptive radiation in angiosperms. There are ten species in the genus Tacca. It is also possible that the mating patterns in the populations of T. chantrieri we examined fluctuate from year to year and that increased outcrossing is limited to years with high population densities of pollinators. These filaments seem to bear resemblance to tiger wiskers and hence its name Tiger Wiskers. At WEV, we observed occasional visits to plants by a few ants, spiders, and flies, but these visits were also not effective in pollination. These features have been assumed to function as a ‘‘deceit syndrome’’ in which reproductive structures resemble decaying organic material attracting flies that facilitate cross-pollination (sapromyiophily). & Li, D. Z. However, the vertical orientation of bracts is unlikely to be an optimal orientation for light capture in shady environments, thus casting doubt on this explanation. Our manipulative field experiment failed to provide evidence for the function of bracts and bracteoles in pollinator attraction. Anthesis commences at the center of the inflorescence with one to four flowers (usually one or two) in anthesis each day. Evolutionary Assurance We propose several hypotheses to resolve this paradox and argue that future studies of pollination syndromes would benefit by investigation of both pollination and mating biology. We investigated pollination and mating in Tacca chantrieri populations from SW China to evaluate this assumption. It is increasingly difficult to find T. chantrieri in its natural We investigated pollination and mating in Tacca chantrieri … We derived the standard errors of selfing rate estimates from the standard deviation of 1000 bootstrap values, using the seed family as the unit of resampling. We also transplanted individuals from natural populations around XTBG to a shady location at XTBG to observe flowering phenology in detail. Regardless of the degree of pollinator specialization involved, a rarely tested but fundamental assumption is that the ultimate function of pollination syndromes is to promote cross‐pollination because of the fitness benefits obtained from outcrossing. Tacca chantrieri. (a) The forest habitat. We observed flower visitors to T. chantrieri in 2002 and 2003 at WEV and XTBG for a total of 90 and 48 h, respectively, during favorable weather. The association between high selfing rates and the sapromyiophilous syndrome in T. chantrieri may occur because the syndrome is a relict condition with no current functional significance. Nevertheless, despite these shortcomings and given our findings concerning the mating system, it seems probable that most of the seed produced by plants in the experiment (including the control) resulted from self‐pollination rather than pollinator‐mediated cross‐pollination. Finally, our manipulations were not conducted at the whole plant level, and our inflorescence level modifications may have been insufficient to illicit differential responses. Indeed, the syndrome could function in other populations of T. chantrieri elsewhere in its range. Introduction. Instead, our results indicate that populations of this species are predominantly selfing and that flowers have several traits that promote autonomous self‐pollination. We used a haemocytometer to estimate pollen production per flower following methods in Dafni (1992). For terms and use, please refer to our Terms and Conditions These include dark flowers and bracts, motile filiform appendages, a trap mechanism involving the stamens and stigma acting as a hood and the absence of nectar. . The inflorescence number for each treatment was initially 30. Tacca ampliplacenta L. Zhang &. We investigated pollination and mating in Tacca chantrieri populations from SW China to evaluate this assumption. Provenienza: Germania. Description This plant is slender with long stems and can reach heights of between 80 and 110 centimetres. The leaves can be as long as 15 inches. Bulbi di Tacca Chantrierei qui presentati in confezione da 5 pezzi. Request Permissions. vs Medicinal ( Its rhizomes are used medicinally in Thailand.) (f) Pollen grains of T. chantrieri adhering to the leg of a stingless bee, The number of pollen grains deposited autonomously on the stigma surface of Tacca chantrieri flowers at three time intervals in relation to anthesis. Its beautiful inflorescence complete with long purplish filaments 12in long forming a flowing forked tail. Their experiments provided no evidence for an obvious adaptive role, and they proposed that this structure may be selectively neutral persisting after its original function was lost. The main finding of our study points to the need to confirm this assumption and warns against inferring patterns of mating from floral morphology alone. Huang for pollen and insect scanning electron microscope observations. Predicting mating patterns from pollination syndromes: the case of “sapromyiophily” in Tacca chantrieri (Taccaceae) Tacca, a genus of tropical herbs, possesses near black flowers, conspicuous involucral bracts and whisker-like filiform bracteoles. Tacca is comprised of ∼10 species of acaulescent forest understory herbs and is the only genus of the monocot family Taccaceae (but see Ding and Larsen, 2000). Fioritura: (Aprile - Agosto). As anthesis proceeds and flowers become pendant, additional pollen grains accumulate on the stigma through autonomous intrafloral self‐pollination (Fig. Therefore, it is hard to imagine how the bracts and bracteoles of T. chantrieri might be important in the dispersal of seeds. We performed two pollination treatments on a single inflorescence of 20–26 randomly selected individuals of T. chantrieri at the WEV and XTBG populations to examine the capacity for autonomous self‐pollination and therefore the importance of insect visitors to pollination. Prior to anthesis, the cymose umbellate inflorescences of T. chantrieri are surrounded by four involucral bracts (two large and two small, see Fig. The … The seed set of inflorescences with bracts and bracteoles removed was not significantly different from unmanipulated inflorescences, suggesting that these structures play a limited role in pollinator attraction, at least at our study sites. It flowers in spring time. Pollen : ovule ratios averaged 49, a value expected in a highly selfing species. Houseplant care: Tacca integrifolia plants … More Information . For example, in small‐flowered species of Araceae, Bromeliaceae, Cornaceae, Euphorbiaceae, and Rubiaceae, showy petaloid bracts probably function in pollinator attraction by enhancing visual display (Weberling, 1992). We consider next several hypotheses that may explain the association between the sapromyiophilous syndrome and high selfing rates in T. chantrieri. The aim of this research was to examine plant growth pattern and flower phenology of T. chantrieri from West Borneo, Indonesia, and … The genetic benefits that result from cross‐ vs. self‐fertilization have been widely recognized since Darwin's pioneering studies on this topic (Darwin, 1876; Charlesworth and Charlesworth, 1987a). Temperatura minima: 12°C. Tacca chantrieri is a flowering plant in the yam family, Dioscoreaceae. AJB publishes peer-reviewed, innovative, significant research of interest to a wide audience of scientists in all areas of plant biology (e.g., biodiversity, structure, function, development, genetics, evolution, reproduction, systematics), all levels of organization (molecular to ecosystem), and all plant groups and allied organisms (cyanobacteria, algae, fungi, and lichens). - "Predicting mating patterns from pollination syndromes: the case of "sapromyiophily" in Tacca chantrieri (Taccaceae)." (Annonaceae) in Sri Lanka. Indeed, genetic analysis of different … Flowering occurs mainly from early April to mid‐May, with sporadic inflorescences being produced until early July. chantrieri are part of a syndrome associated with sapro-myiophily, as proposed in the literature for Tacca species in general, T. chantrieri populations in SW China had been selected by Zhang et al.

For treatment 3, the focal inflorescence was prevented from moving in the wind by securing the inflorescence axis (scape) to a wooden stick. 2a, b). Tacca integrifolia is a herb growing from a thick, cylindrical rhizome.The leaf blades are borne on long stems and are oblong-elliptical to oblong-lanceolate, some 50 by 20 cm (20 by 8 in), with tapering bases and slender pointed tips. Pollen loads on stigmas indicated autonomous self‐pollination, some of which occurred prior to flower opening. This indicates that a high proportion of the seed produced in each population results from self‐fertilization. Predicting mating patterns from pollination syndromes: the case of “sapromyiophily” in Tacca chantrieri (Taccaceae) Tacca, a genus of tropical herbs, possesses near black flowers, conspicuous involucral bracts and whisker-like filiform bracteoles. Working off-campus? Two days prior to anthesis, the flowers were emasculated to prevent prior self‐pollination. Tacca flowers are dark purple, brown, or near black in color and are actinomorphic, hermaphroditic with six stamens. Temperatura ottimale: La pianta gradisce temperature comprese tra i 28° e 29°.

Wiley has published the works of more than 450 Nobel laureates in all categories: Literature, Economics, Physiology or Medicine, Physics, Chemistry, and Peace. The evolution of plant reproductive ecology in China. Hence the P : O (pollen : ovule) ratio of T. chantrieri is 49 (Table1). Among the four populations of T. chantrieri examined in this study (Table 2), estimates of the population‐level maternal selfing rate (sm) based on three polymorphic allozyme loci averaged 0.86 (range 0.76–0.94). Pollinator visitation was infrequent and bagged flowers set abundant seed. For example, we did not attempt to measure visitation rates because pollinators were so infrequent at the site. in two showy species, Tacca integrifolia Ker Gawl. bat flower This is a tropical perennial with bold, undivided leaves forming a rosette above the underground stem. Its pollination takes place through small mammals and rodents who eat its fruit. We also performed hand cross‐pollinations using pollen from plants up to 10 m away on 35 flowers randomly selected from 10 inflorescences. Contrary to this expectation, populations were highly selfing. Integrating ecological and evolutionary processes in a spatial context. The female fertility of the two experimental treatments was not significantly different from the control treatment. Contrary to this expectation, populations were highly selfing. As the bracts open they reveal about a dozen flowers on pendulant stems. Stevenson (2004) also suggested that the dark‐colored flowers and large bracts were likely to be associated with fly pollination (and see Endress, 1995). Grow it in a … Our studies of the floral biology and mating system of T. chantrieri indicate that most seeds produced in populations result from self‐fertilization. ©2000-2021 ITHAKA.

In our field experiment, the percentage fruit set and seed set did not differ significantly among the three treatments (fruit set: control, 67.8 ± 3.69 [mean ± SE, N = 23]; bracts removed, 65.2 ± 3.74 [N = 23]; staked, 72.7 ± 3.52 [N = 25]; seed set: control, 45.8 ± 3.29; bracts removed, 44.6 ± 2.36; staked, 47.9 ± 2.77; P > 0.1 for all comparisons). We investigated pollination and mating in Tacca chantrieri populations from SW China to evaluate this assumption. The purpose of the bracts is to protect the flowers while they mature. American Journal of Botany (c) A cross‐section of the flower illustrating the close proximity of the stigma and anthers. Jack (Dioscoreaceae) by Female Ceratopogonid Midges (Diptera: Ceratopogonidae) All pictures are contributed by our community. Dark floral colors, the presence of long filiform appendages or bracts, floral traps, the absence of nectar, and a decaying odor are common features of the sapromyiophilous syndrome in other families of flowering plants (e.g., Asclepiadaceae, Aristolochiaceae, Araceae, Orchidaceae; reviewed in Fægri and van der Pijl, 1971; Proctor et al., 1996). This distinctive flowering plant is native to Myanmar (Burma, to us old-timers) and Thailand (Siam, to the really old-timers). Bat Flower, Tacca chantrieri. Tacca chantrieri has extravagant floral displays and a high investment in reproductive structures that lead to the expectation that it is largely More Information; Offers: Buy More Save More: Reviews . Our study of mating patterns in T. chantrieri was conducted in four populations during a single flowering season. (2005) to investigate pollination and mating pattern. The flower stem develops from the base of the plant, and it can be around 24 inches long. In most autogamous plants, fruit to flower ratios are close to 1.0, suggesting that the reproductive economy of the T. chantrieri populations that we investigated may not be fully adjusted to high levels of selfing. These include the close proximity of anthers and stigmas within flowers, anther dehiscence prior to flower opening, and additional self‐pollination when flower stalks bend downwards on the second day of anthesis (delayed self‐pollination). — American Journal of Botany 92: 517–524. Percentage fruit set in hand cross‐pollinations was 25.7, with the percentage seed set of fruits 42.3 ± 7.3. We thank Drs. Also, we only compared maternal reproductive success (fruit and seed set) in the three treatments and not male fitness resulting from pollen dispersal between plants. Visitors were insects observed on inflorescences, whereas pollinators were insects that consistently contacted both anthers and stigmas and had pollen grains deposited on their bodies. Contrary to this expectation, populations were highly selfing. This species has four large, dark‐purple bracts and long bracteoles, giving the inflorescence a striking appearance in the understory of the tropical forests that the species inhabits (Fig. Such temporal variability in selfing rates has been reported in other self‐compatible animal‐pollinated species (Harding and Barnes, 1977; Barrett et al., 1993). Curious, bat-like inflorescence both in shape and color, with wide spreading, wing-like bracts of rich maroon-black, accompanied by long trailing filaments or "whiskers"; the small black flowers are succeeded by heavy berries; corrugated olive-green leaves with oblique base. — Annals of Botany 98: 449–457.
