摘要
感染炭疽病的枇杷叶片 H2 O2 含量明显提高 ,可溶性蛋白质、叶绿素、类胡萝卜素含量以及叶绿素 a/叶绿素 b、叶绿素 /类胡萝卜素下降 ,叶绿素可变荧光产量 (Fv)、PS 原初光能转换效率 (Fv/ Fm)、PS 的潜在活性 (Fv/ Fo)及光合量子产额 (Yield)均受到抑制 .供试的抗、感病品种解放钟、早钟 6号上述指标存在明显差异 ,表明了枇杷品种对炭疽病的抗性与 H2 O2 的累积 ,叶绿素、类胡萝卜素、蛋白质的降解 。
The content of H 2O 2 in loquat leaves that infected by antracnose obviously increased. On the contrary,soluble protein, chlorophyll, and carotenoid decreased, and so did the ratio of chlorophyll a to b, and chlorophyll to carotenoid. In addition, Fv, Fv/Fm, Fv/Fo and Yield were also inhibited. These indexes in the resistant variety greatly differed from those in the susceptible variety. It indicated that the resistance of loquat to anthracnose was closely related to the accumulation of H 2O 2, the degradation of chlorophyll, carotenoid and protein,and the parameter of chlorophyllous fluorescence.
