摘要:
本文采用了抗性不同的大豆品种,在3～ 4叶期接种,并于接种后1～ 10天内连续取样,然后测定其接种后叶片内叶绿素的含量。试验结果表明: 无论是抗病品种,还是感病品种,在病菌侵入的初期,叶绿素a、b的含量都有所下降; 在病菌侵染后7～ 10天时,感病品种叶片内叶绿素a、b含量比未接种对照低,而抗病品种叶片内叶绿素a、b含量均明显高于未接种对照; 另外,致病力不同的生理小种对叶绿素a、b含量变化的影响不同, 7号生理小种对叶绿体的破坏能力最强,其次为6号生理小种,而4号生理小种则最弱,其中1号, 2号生理小种居中。抗病品种叶片内叶绿素a /b的比值明显高于感病品种,初步认为叶绿素a /b的比值可作为大豆品种对灰斑病抗性鉴定的一种生化指标。
