小麦抗寒生理生化特性与分子机理研究进展

Research Progress of Physiological and Biochemical Characteristics and Molecular Mechanism of Wheat Cold Resistance

低温严重威胁着小麦生产,研究小麦抗寒性机理具有重要意义。本文从内源激素和游离氨基酸含量及保护性酶活性变化、抗寒基因的染色体定位、冷诱导基因、小麦抗冻蛋白等方面对国内外小麦抗寒性研究进展进行了综述。

Wheat production is severely threatened by low temperature, so the study on mechanism of wheat cold resistance is of great importance. In this paper, the latest research progress of wheat cold resistance was summarized in variations of endogenous hormones, free amino acids and protective enzyme activity, loca-tion of wheat cold-resistant genes, cold induced genes and antifreeze protein.
