小麦不同品种耐湿性生理指标综合评价及其预测

 把小麦各生理指标的耐湿系数作为衡量小麦单项耐湿能力大小的指标 ,用主成分分析法将各单项耐湿系数综合成几个新的相互独立的综合指标 ,再利用隶属函数求出每一品种耐湿性的综合评价值后 ,便可较准确地评价各品种的耐湿性。同时利用耐湿性的综合评价值与单项指标间建立的最优回归方程可以预测其它小麦品种耐湿性的大小

Comprehensive Evaluation and Forecast on Physiological Indices of Waterlogging Resistance of Different Wheat Varieties

The physiological indices of waterlogging resistance were synthesized, which were used to value the wheat varieties' single capacity of waterlogging resistance to some new independent comprehensive indexes by principal component analysis. The comprehensive value of different wheat varieties' waterlogging resistance was obtained by using subordinative function. So the waterlogging resistance of different wheat varieties can be evaluated. At the same time, other varieties' waterlogging resistance can be forecasted by using the best regressive function that was founded by the comprehensive value of waterlogging resistance and the value of single index.
