摘要
采用综合指标法 ,以灰色系统理论为评估模型 ,在分苗期、花荚期、灌浆期 3个生育期对绿豆突变体及对照的抗旱性进行了研究 ,发现了一个抗旱表现良好的突变体 (Al) ,该突变体 3个时期的抗旱性都超过CK1 ,苗期和灌浆期的抗旱性还超过CK2 ;同时还发现不同时期的抗旱强弱次序不同 ,因此 ,不能以一个时期的抗旱性代替整个生育期的抗旱性。
The induced mung bean mutants were studied at three stages(the seedling stage,the flower and pod stage,the filling stage)by the means of synthetical indexes and the theory of grey systems.An excellent mutant with better drought resistance character than CK1 in all three stages and than CK2 in the seedling and the filling stages was found.As the orders of the drought resistance varied with the growth period,the drought resistance of one period can't replace that of the whole life period.
