摘　要：

低温是非传统植胶区巴西橡胶树(Hevea brasiliensis)种植的重要限制因子。低温能够引起巴西橡胶树细胞结构、原生质胶体特性、水分状况、细胞渗透压、光合作用、呼吸作用、物质代谢和保护酶系统等发生一系列改变, 最终影响植株的生长发育。目前已从巴西橡胶树中克隆出一些抗寒相关基因, 但是巴西橡胶树响应低温胁迫的调控机制仍不十分清楚。本文综述了巴西橡胶树对低温逆境响应的生理特征及其应答调控机制, 以期为深入研究巴西橡胶树抗寒机制提供参考。

Abstract:

Low temperature is an important limiting factor for Hevea brasiliensis cultivating in the non-traditional areas. Changes referring to cell structure, colloid properties of protoplasm, water status, osmotic pressure of cell, photosynthesis, respiration, substance metabolism, and protective enzyme system, are induced by low temperature. Thus the growth of H. brasiliensis is influenced. Some genes related to cold resistance have been cloned in recent years, however, the mechanism of H. brasiliensis responded to low temperature is far to be clear. In this paper, we summarize the physiological characteristics of H. brasiliensis in response to low temperature stress and its regulation mechanisms. It provides references for further research on the mechanisms of cold resistance in H. brasiliensis.

Key words: Hevea brasiliensis; low temperature; physiological characteristics; regulation mechanisms
