摘要: 茶树原产于中国西南地区,喜温暖潮湿的气候条件,其中水分对茶树的生长十分重要。笔者对茶树在干旱胁迫条件下的抗旱机理研究以及抗旱育种的现状进行综述,针对当前研究中存在的问题并结合当前分子生物学的发展,提出今后在茶树抗旱研究的研究重点:一是利用现代功能基因组研究技术,发掘更多的抗旱基因,深入研究茶树的抗旱机制;二是加强茶树转基因工程的研究。

Abstract: Camellia sinensis originates in southwest China, and lives in warm and humid climate conditions. Water plays an important role in the growth of tea plant. In this article, the research progress of drought resistance mechanisms of Camellia sinensis, including the change of physiological and biochemical substances and the molecular-level, were reviewed. The breeding of Camellia sinensis under drought condition was also discussed. According to the research status of molecular biology, some suggestions for the existing problems were put forward. Firstly, more resistant genes and drought resistance mechanisms should be explored by means of functional genomics research techniques; secondly, the transgenic engineering research of tea should be strengthened.
