| 1 | Reproductive Biology and Prospects for Conservation of Caldesia parnassifolia (Alismataceae)——A Threatened Monocot in China显示文摘Caldesia parnassifolia (Bassi ex Linn.) Parl. in China has declined in number in r ecent years and is increasingly faced with the risk of extirpation arising from anthropogenic changes associated with rapid urbanization and expansion of both agriculture and infrastructure. To aid in provision of the data needed for effective conservation of the species, studies on the habitat, pollination ecology, and breeding system of C. parnassifolia were carried out on natural populations occurring in Southeastern China. Flowering in the study populations extended for more than eighty days beginning in early summer. Floral anthesis occurred in the morning hours and proceeded rapidly, lasting about 45 min. Flowers lasted ca. 8 h. Caldesia parnassifolia is self\|compatible; however autogamy resulted in lower seed set than geitonogamy and xenogamy as well as free pollination. The data on pollen/ ovule (P∶O) ratio is consistent with a partially selfing and outcrossing mating system. Interpopulational crosses yielded similar seed set to within\|population crosses. Agamospermy did not occur in the study populations. Propagation is achieved through seeds as well as through turions which commonly occur in the inflorescences. Flies (Insecta; Diptera) were the most frequent visitors to the flowers of C. parnassifolia; however bees (Insecta; Hymenoptera) composed a larger proportion of effective pollinators. The Syrphidae species Sphaerophoria indiana (Bigot) presents evidence of oligolectic foraging behavior. Recommendations are made on the immediate steps necessary for conservation of Caldesia species in China. | Gituru Wahiti Robe rt, Wang Qing\|feng , Wang Yong, Guo You\|hao Colleg e of Life Sciences, Wuhan University, Wuhan 430072, Hubei, China | 2003 | Wuhan University Journal of Natural Sciences2003，8，01A： | 2 |
