| 摘 要： | 为了明确蔓枯病对厚皮甜瓜植株早衰的影响,以抗性水平不同的厚皮甜瓜‘玉菇'和‘夏蜜'为试材,利用蔓枯病菌孢子悬浮液对甜瓜进行接种,在接种后测定了不同节位叶片内SOD、CAT和POD的活性变化以及Chl和Pr的含量.试验结果表明,蔓枯病加速了厚皮甜瓜植株的早衰,当植株在受到蔓枯病菌侵染后,叶片中的SOD和CAT活性均迅速上升,而后逐渐下降,POD活性一直呈上升趋势,‘夏蜜'的SOD和CAT活性均高于‘玉菇',而‘玉菇'的POD活性高于‘夏蜜'.‘夏蜜'的Chl和Pr的含量均高于‘玉菇',在接种后都呈下降趋势,但‘夏蜜'比‘玉菇'下降的慢.不同节位叶片在受到病菌侵染后,早衰程度也有所差异,节位低的叶片受蔓枯病菌的影响较大,衰老也快.

| Abstract: | To understand the effects of gummy stem blight on retardation of early-senescence of muskmelon,dynamic changes of activities of superoxide dismutase(SOD),catalase(CAT) and peroxidase(POD),the contents of chlorophyll(Chl) and soluble protein(Pr) in Xiami and Yugu on different nods were analyzed after inoculation by Didymella bryoniae.The results showed that,SOD and CAT activities rapidly increased after inoculated 1 day(d),and then reduced,the SOD and CAT activities were higher in xiami than in Yugu.The POD ... |
