金合欢属植物的生殖生物学研究进展

Advances in Reproductive Biology of Acacia

金合欢属植物具有较高的经济价值,我国引入已近百种。自引入以来,种子园经营及管理出现诸多问题,加之林木经营者对本属植物生殖学了解欠缺,迫切需要加深这方面的认识。笔者对半个世纪国外在金合欢属植物生殖生物学方面的研究成果进行整理,对其生殖生物学研究进行综述,包括花部生物学特征、雄蕊的发育、开花传粉及繁育体系;同时讨论了种子园座果率及种子产量低下的原因,并对以后的研究提出了展望,以期为生产中提高种子园的管理效率起到指导意义。

About 100 Acacia species have been introduced into China for their considerable economic value.However,many problems have emerged during the operation and management of seed orchard since their introduction.The fact that planters know little about Acacia reproductive biology would make things worse.Therefore,a deep knowledge to the reproductive biology of Acacia is urgently needed.In this paper,the advances in more than half a century＇ s research,including floral morphology,characters and development of anther and pollen,anthesis and pollination,breeding system,were reviewed.And the reasons for low fruit and seed set were discussed as well.Advices for future＇ s study were given in order to manage seed orchard.
