英文摘要: The pollination biology of Musella lasiocarpa (Franch.) C. Y. Wu ex H. W. Li, a monotypic genus in the banana family (Musaceae) endemic to southwestern China, was investigated. Floral phenology, nectar production, and flower visitors were observed, measured, and recorded. Bagging experiments and comparative breeding system studies were carried out at different study sites and in different seasons. Our results revealed four important aspects of the reproductive biology of Musella. 1) This species blooms year round, but most flowering is concentrated from February to August. The longevity of female flowers is greater than that of male flowers and opening of both types of flowers occurs at anytime during the day, but is concentrated in the morning. 2) Although nectar is produced uniformly while flowers are open, the nectar volume and rate of female flowers are significantly higher than that of male flowers. 3) Insects, such as bumblebees (Bombus eximius and B. montivolans), honeybees (Apis cerana and A. florea), and wasps (Vespa mandarinia) are the primary floral visitors and show a preference for female flowers. 4) Both fruit and seed set are pollinator-limited at both study sites. A comparison of the floral biology and pollination characteristics among the three genera in the banana family suggests that insect pollination has played an important role in the reproductive isolation and breeding system evolution of Musella.
