摘要
不同生态点的条件下 ,以单株成铃在产量构成因素中的变异系数最大 ;据关联分析结果表明 ,衣分是制约单株成铃、单粒籽棉重、衣指的主导因素 ,衣指是制约衣分的主导因素 ,而单粒籽棉重是制约子指的主导因素 ;据通径分析结果表明 ,衣分对产量的综合直接作用最大 ;而据主成分分析表明 ,在湖南特殊的环境条件与栽培条件下单株成铃、单粒籽棉重、衣分三者的信息量占总信息量的 82 6 5 79% ,基本反映产量构成因素的基本情况。
The results showed that the variation coefficient of boll per plant is the largest in yield properties;By the interrelative methods of grey systematic theory, the lint percentage is one of significant factors that affects boll per plant?seed cotton per plant?lint index; lint index is one of significant factors that affects lint percentage;Seed cotton per plant is one of significant factors that affects seed index. By restoring menstrual analyses, The direct action to the yield of lint percentage is the largest; On the grounds of the primary component analysis that boll per plant?seed cotton per plant?lint percentage is 82.6579% of the gross information content under the condition of special ecosystem and cultivation in Hunan.
