摘要: 该项研究采取指标定性与定量,分析与综合,反复测定与田间验证结合的方法,建立和完善利用多种鉴定方法(田间多点联合鉴定、模拟逆境筛选和实验室测定)及综合指标评价作物抗寒性的技术体系,并提出了筛选抗逆“源”的方法。同时概述了小麦寒胁迫膜蛋白的种类、变化与抗冻性的关系以及介绍了作物抗寒性分子基础的探索。

关键词: 抗寒性,鉴定原理,鉴定技术体系,寒胁迫蛋白,抗寒基因,调控机制。

Abstract: A method of repeated determinations combined with field verifications not only quantitatively and qualitatively but also analytically and synthetically was used in the studies with some indexes.A set of technical systems for evaluating cold-resistance in crops has been established and improved with
