The ability of the resistance of rice cultivars against Sogatella fur- cifera (Horvath) is closely correlated with the cuticula structure featued of the silicon cell chain and silicon cell group, spines and setae, cork cell and wax layer.

• 水稻抗御白背飞虱Sogatella furcifera(Horvath)的能力,与水稻叶鞘表皮组织的矽细胞群、矽细胞链、刺毛、刚毛、木栓组织、蜡被层密度等密切相关。 这些结构的数值化指标。
