| 摘 要： | 综述了姜科Zingiberaceae植物繁育系统和传粉生物学方面的研究及其进展。姜科有50余属1500多种,是一个泛热带分布的、动物传粉的单子叶植物大科。姜科植物中存在着雌花两性花异株、雄花两性花同株、花柱卷曲性、雄性先熟、自交不亲和等多种性表达方式和花部机制。姜科植物重要的传粉动物包括各种蜂类、天蛾、蝴蝶、鸟类等,不同的传粉动物对应不同的花部特征。在相对有限的研究中,姜科植物展现出了一些独特的传粉和繁育机制,在豆蔻属Amomum、山姜属Alpinia等植物中发现的花柱卷曲性被认为是植物界中一种独特的促进异交的行为机制,在对黄花大苞姜Caulokaempferia coenobialis的研究中发现了植物界中一种全新的花粉滑动自花传粉机制,这些新的研究和发现丰富了我们对姜科植物传粉和繁育系统多样性的认识。本文提出了今后姜科植物繁殖生物学研究的建议:对更多未知姜科植物类群的传粉和繁育系统进行研究;从系统发育的角度开展姜科不同类群植物的传粉和繁育系统的演化研究;对花柱卷曲性这一独特的性多态现象开展全面深入的研究。

| Abstract: | In this paper we presented a review of the advances in the studies of breeding system and pollination biology of gingers. The Zingiberaceae is a large family of animal-pollinated pantropical monocotyledons with more than 1500 species in ca. 50 genera. There are many kinds of sexual variations occurring in the ginger family, such as gynodioecy, andromonoecy, flexistyly, protandry and self-incompatibility. Major pollinators include bees, hawkmoth, butterfly and birds, and different pollinators correspond with different morphological characteristics of flowers. Among the relatively few studies on the pollination biology, members of this family display some unique pollination mechanisms and breeding systems. Flexistyly, found in the genera of Amomum and Alpinia, is regarded as a unique behaviour mechanism that encourages outcrossing; a new self-pollination mechanism has been discovered in Caulokaempferia coenobialis, in which a film of pollen is transported from the anther by an oily emulsion that slides sideways along the flower’s style and into the individual’s own stigma. These studies and discoveries give us a better understanding on the diversity of pollination and breeding systems of gingers. For future research, we suggested that more studies should be carried out on the pollination and breeding systems of gingers in a wider range, and phylogenetic research should be conducted to understand the evolution of pollination and breeding system in Zingiberaceae, and for the flexistyly, more detailed studies should be done about this unique sexual polymorphism. |
