树木发育阶段理论及其在橡胶树育种中的应用(综述)

A REVIEW OF THE STUDIES ON DEVELOPMENTAL PHASES OF TREES AND ITS APPLICATION FOR HEVEA BRASILIENSIS BREEDING

摘要:

近一个多世纪来,树木发育阶段理论的应用研究取得了令人瞩目的成就,在果树育种、造林、园艺等领域得到广泛应用并取得了巨大的经济效益。与此形成鲜明对比的是,树木发育阶段理论研究的核心内容如发育阶段转变的遗传基础、分子机制等方面的基础研究工作却进展缓慢,对各个阶段的发育特性和利用潜力认识不足,在一定程度上限制了该理论在生产实践中的应用和推广范围。本文就树木发育阶段理论的研究现状、存在问题及在橡胶树育种中的应用等进行了综述和探讨。

Abstract:

In this paper the theory of developmental phases in trees, the studies on its molecular biology and the heredity of traits during phase change,and the application of theory of developmental phasesin the breeding of Hevea brasiliensis are presented. The distinction of features between juvenile and adult phases, and the phase change in relation to rubber production are discussed.
