45个春大豆品种豆荚结构特征及其对食心虫抗性评价OA北大核心CSCDCSTPCD
The Structure of Soybean Pod of 45 Spring Soybean Varieties and Evaluation of Resistance to Leguminivora glycinivorella
为解析豆荚结构特征及其与大豆品种对食心虫抗性的关系,对45份东北春大豆品种的荚毛密度、长度、颜色、形状及荚皮各层组织厚度等结构特征进行观测分析,提出相对抗性系数法对大豆品种抗虫性进行评价,结果表明:45个品种荚毛密度的频次分布符合韦布尔方程Y毛密度=9.21(1-EXP(-((X-2.77)/2.90)^-6.37)),荚毛长度的频次分布符合双曲线方程Y毛长度=-151.28+ 138.39X-29.46X2;荚皮表皮角质层、皮下厚壁细胞层、中果…查看全部>>
To analysis the relation between characteristics of pods structure and resistance to Leguminivora glycinivorella,pod hair density,length,color and thickness of different layers of 45 northeast spring soybean were observed analysis.The soybean varieties resistance was evaluated by resistance coefficient method.The results showed that the frequency distribution of pod hair density in 45 varieties accorded with Weibull equation ydensity =9.21 (1-exp(-((x-2.77)/…查看全部>>
