小麦春季抗寒性研究进展

Research Advances on Cold Resistance of Wheat( Triticum aestivum L. ) in Spring

近年来气候异常现象频繁发生,春季低温冻害已成为影响小麦生产的限制因素之一。关于小麦春季抗寒性已开展大量研究,并取得一定进展。本文根据国内外相关研究报道分别从小麦对倒春寒敏感期的鉴定、响应倒春寒的生理生化、倒春寒对小麦产量及其构成因素的影响、小麦春季抗寒性分子生物学研究等方面进行概述,并据此探讨了此领域研究中存在的问题及今后可能的研究思路。

In recent years, the adverse agroclimate events has occurred frequently. The low temperature freeze injury in spring has become one of the limiting factors of wheat production. The extensive researches a- bout cold resistance of wheat in spring have been carried out and made some progresses. In this paper, we summarized the aspects of the sensitive period, physiological and biochemical changes and yield and its com- ponents of wheat to late spring coldness and the molecular biology studies on cold resistance of wheat in spring, etc, based on the domestic and foreign studies. We also discussed the existing problems and possible research ideas for future studies.
