| 摘 要： | 对抗病玉米品种陕单931和感病玉米品种西农11号在抽雄初期接种禾谷镰刀菌孢子悬浮液,于接种后测定茎秆髓部组织内苯丙烷类次生代谢物木质素和绿原酸的变化。结果表明,玉米植株原生木质素与玉米对茎腐病的抗性无关,仅诱导产生的木质素在玉米的抗病性中起作用。并证实玉米植株受到镰刀菌侵染后可产生对镰刀菌有抑制作用的物质。

| Abstract: | In order to understand the relationship between metabolites of phenylpropanoid metablism and resistance of corn to stalk rot,and to explore the resistant mechanism of corn to stalk rot,which might be used to assess the resistance to stalk rot in corn breeding,changes of metabolites of phenylpropanoid metablism including lignin and chlorogenic acid in the pith tissue of corn stalk of resistant variety Shaandan 931 and susceptible variety Xinong 11 inoculated with F.graminearum were mainly studied.It was clarified that the lignin produced originally in corn plant had no relation to resistance of corn to stalk rot.It was the induced lignin produced by the corn plant after the infection of F.graminearum that showed contribution to the resistance only.It was proved that corn plant could produce some substances that could suppress the growth of F.graminearum.One of the substances was chlorogenic acid.It was postulated that resistance to stalk rot had a close relationship with the accumulation of induced lignin and chlorogenic acid in plant pith tissue of corn stalk after the infection of F.graminearum. |
