以抗倒性不同的9个油菜品种为材料,分析了倒伏指数和茎秆生化成分及农艺性状的关系,结果表明,倒伏指数与粗纤维、碳含量、根颈皮层干鲜比、株高、主花序长的关联度高;倒伏指数和根颈皮层干鲜比呈显著正相关(r=0.690*).抗倒品种中双9号的粗纤维、木质素、蛋白质、氮含量分别是不抗倒品种湘杂油2号的0.763、1.189、1.456、1.46倍;中双9号在成熟期表现强的生长特性,株型紧凑,株高适中,主花序较短,分枝起点低,结角密度大.

Relationship between lodging were analyzed by grey relational analysis after coarse fiber, carbon content, dry weight/fresh index and biochemistry components of stem, agronomic characters comparing 9 rapeseed varieties. The results showed that content of weight of cortex of root colla, plant height, length of main inflorescence have stronger grey correlation with lodging index than other traits. The result of between dry weight/fresh weight of rhizome cortex was significant correlated. line, its content of coarse fiber, lignin content, protein content and Zhongshuang No. 9 was a lodging index ...
