tacca chantrieri pollination

Elsewhere, Lamborn and Ollerton (2000) used floral manipulations to investigate the function of the dark central floret in inflorescences of Daucus carota (Apiaceae). We used a haemocytometer to estimate pollen production per flower following methods in Dafni (1992). 2Xishuangbanna Tropical Botanical Garden, The Chinese Academy of Sciences, Yunnan 666303, China; 3Department of Botany, University of Toronto, 25 Willcocks Street, Toronto, Ontario, Canada M5S 3B2. 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. Given their leaflike structure and size, the large involucral bracts in T. chantrieri could also be a significant source of photosynthetic carbon for developing fruits. These tropical evergreen flowers produce large, pure white petals centred by small, sombre, drooping flowers and long whiskerlike bracts, all resembling a bat's face. Demographic factors and mating patterns in angiosperms. Also known as: Bat Plant, Cat’s Whiskers, Devil Flower, Black Bat Flower, Bat Head Lily, Devil’s Tongue, Black Tacca, Jews Beard or Voodoo Flower . 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). 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). 2. Access supplemental materials and multimedia. In addition, our study raises several general questions concerning pollination and mating in animal‐pollinated plants. Although most displays involve elaborate floral designs or the aggregation of flowers into showy inflorescences, in some families nonfloral structures are the principal organs of pollinator attraction.

Although the possession of a particular syndrome rarely restricts visitation to a single animal group (Baker, 1963; Waser et al., 1996; Johnson and Steiner, 2000), there is general agreement that pollination syndromes have been shaped by past coevolution between plants and their most effective pollinators (Stebbins, 1970; Fenster et al., 2004; but see Aigner, 2001). Do mutualisms matter? 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. 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. Pollen loads on stigmas indicated autonomous self-pollination, some of which occurred prior to flower opening. 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. Learn more. Tacca chantrieri, or the black bat plant, grows from underground rhizomes; and produces large-green leaves and long-stemmed flowers. II. Zhang, Ling et al. that is dominated by Tetrameles nudiflora (Datiscaceae) and Horsfieldia tetratepala (Myristicaceae). Plants are 50–100 cm tall with tubers or creeping rhizomes and alternate, elliptic, entire leaves. Allocations to pollen, seeds, and pollination mechanisms in self‐fertilizing plants. A fetid odor occurs in many sapromyiophilous species (Faegri and van der Pijl, 1971; Proctor et al., 1996). 3). Tacca integrifolia flowers are presumed to be pollinated by flies. 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. 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). 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.

Experimental assessment of the functional morphology of inflorescences of. This led the authors to suggest that most bat plants are self-pollinated. Pollinator visitation was infrequent and bagged flowers set abundant seed. During flowering, the most conspicuous features of display in T. chantrieri are the large, purple involucral bracts and long, filiform bracteoles (Fig. Adaptive radiation in angiosperms. material attracting flies that facilitate cross-pollination (sapromyiophily). and Tacca chantrieri André, demonstrate a very high degree of geograph-ical population stratification, consistent with a hypothesis of self-pollination (Zhang et al. Selfing rates estimated in four populations using allozyme markers averaged 0.86 (range 0.76-0.94), thus corroborating this inference. vs As expected, based on these mating patterns, measurements of the parental inbreeding coefficients (F) indicate that the parental generation is significantly inbred (Table 2). An alternative possibility is that the bracts and bracteoles function in seed dispersal and serve to attract dispersal agents to plants. We investigated pollination and mating in Tacca chantrieri populations from SW China to evaluate this assumption. We begin by describing the floral biology of T. chantrieri, focusing on traits associated with pollination and mating. Ethnobotanical Uses: Edible Plant Parts (Edible Leaves, Edible Flowers) Food (Fruit & Vegetable : Its leaves and inflorescences are used in curries.) 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. (a) The forest habitat. — Annals of Botany 98: 449–457. Read your article online and download the PDF from your email or your account. 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. The flower stem develops from the base of the plant, and it can be around 24 inches long. Other vertebrates, such as … Generalization versus specialization in plant pollination systems. Bulbi di Tacca Chantrierei qui presentati in confezione da 5 pezzi. and Tacca chantrieri André, demonstrate a very high degree of geographical population stratification, consistent with a hypothesis of self-pollination (Zhang et al. Despite the possession of traits commonly associated with fly pollination by deceit, we recorded no flies acting as pollinators of T. chantrieri. 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). With spatial and temporal variation in pollinator service, even low levels of fly‐mediated outcrossing may be sufficient to maintain the sapromyiophilous syndrome, if the fitness benefits of outcrossed progeny are sufficient to outweigh the costs of selfing and investment in display. However, our finding of similar levels of seed set in bagged and open‐pollinated flowers at the XTBG population (although not at WEV) implies that most selfing probably arises by autonomous means. 1). Zona geografica: Sud-Est asiatico Asia. 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). and you may need to create a new Wiley Online Library account. 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. Proceedings of the Royal Society B: Biological Sciences. American Journal of Botany, March 2005 v. 92, no. When they split along their sides, numerous 0.5cm (0.25 inch) seeds are revealed embedded in a sticky pulp. Zhang, L., Li, Q. J., Li, H. T., Chen, J. However, a role in dispersal seems unlikely because the bracts and bracteoles wither and senesce before fruits are mature. Floral characters of Tacca chantrieri based on samples from the XTBG population. 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. At XTBG, we observed occasional crickets and ants on flowers; neither of these visitors were effective as pollinators because sex organs were not contacted. However, in species in which this occurs, reduced investment in both floral and inflorescence display is usually associated with predominant selfing (Ornduff, 1969; Charnov, 1982; Schoen, 1982; Lloyd, 1987; Morgan and Barrett, 1989). - "Predicting mating patterns from pollination syndromes: the case of "sapromyiophily" in Tacca chantrieri (Taccaceae)." This seems doubtful in the case of T. chantrieri, as extreme specialization would be unlikely in a species in which the only apparent floral reward (pollen) is easily accessible to most insect visitors. ©2000-2021 ITHAKA. Tacca chantrieri inhabits moist and shaded understory habitats in tropical forests of SE Asia (Fig. Pollination syndromes are suites of convergent traits that have evolved independently in unrelated plant lineages functioning to attract particular groups of animal pollinators (e.g., bird, bat, fly, hawkmoth) (Fægri and van der Pijl, 1971; Proctor et al., 1996). In Yunnan Province, SW China, the region in which our studies were conducted, the species flowers from April to July. Tacca, a genus of tropical herbs, possesses near black flowers, conspicuous involucral bracts and whisker‐like filiform bracteoles. 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.
