| 摘 要： | 以抗倒伏性不同的5个油菜品种为材料,综合考察株高、单茎鲜重、抗折力等各种因素对油菜抗倒伏能力的影响,并探讨采用倒伏指数评价油菜抗倒伏性的准确性。结果表明:中双9号抗折力显著高于其他4个品种,倒伏指数显著低于其他4个品种,表现出较强的抗倒伏性;通径分析结果表明,抗折力与倒伏指数关系最密切;倒伏指数与倒伏程度呈极显著正相关(r=0.95*)。因此,以倒伏指数为衡量标准,能客观、准确地评价油菜的抗倒性。

| Abstract: | The components of lodging index involved the plant height,fresh weight of stem and breaking resistance were evaluated in 5 samples of rapeseed with different lodging resistance.The results were as follows:(1)Zhong Shuang 9 has more highter breaking resistance and showed significantly lower lodging index than the other 4 species.(2)The result of path analysis showed that breaking resistance is closely related to lodging index.(3)The result also showed the lodging index has extremely relevance correlation to lodging degree.So"lodging index"had been applied in the evaluation of rapeseed lodging resistance. |
