【摘要】 对抗感不同的野生大豆接种疫霉菌后木质素含量的变化进行了研究,结果表明:在接种疫霉菌之前,抗感野生大豆的木质素含量平均值无明显差异;在接种疫霉菌之后,抗病野生大豆茎中木质素含量在病程的大部分时期高于对照,且在病程前期比感病野生大豆增幅大;在病程的大部分时期,抗感野生大豆叶中木质素的含量低于对照。更多还原

【Abstract】 The change of lignin content in wild soybeans inoculated with P. sojae was studied in this paper. The results showed that there was no significant difference between the resistant and susceptible wild soybeans in the content of the lignin before inoculated with P. sojae. The lignin content in stems of resistant wild soybeans increased compared with the control at most of the pathogenicity stages,and the increase rate was also higher than that of susceptible soybean varieties. The lignin content of resistant and susceptible wild soybeans decreased compared with the control at most of the pathogenicity stages in leaves.更多还原
