摘要: 研究了对黄萎病不同抗性棉花品种在接菌前后酶活性与酚类物质含量的变化。结果表明:棉花对黄萎病的抗性与棉株组织中的过氧化物酶(POD)、多酚氧化酶(PPO)、苯丙氨酸解氨酶(PAL)活性及酚类物质(主要为二元酚)含量密切相关。不同抗感黄萎病棉花品种接种病原菌后,4个指标都有不同程度地提高,并于接种后3~5d内出现峰值,峰值高低与抗性程度呈正相关。

关键词: 棉花, 黄萎病, 接种, 酶活性, 酚类物质

Abstract: The activity of peroxidase(POD)?polyphenol oxidase(PPO)?phenylalanine aminolyase (PAL) and the content of phenols in the roots and leave of 4 cotton cultivars with different resistance to V.dahliae after inoculation were studied.The results showed that the activity of POD?PPO and PAL all were increased remarkably in 4 cotton cultivars after inoculating pathogen.Normally activity of enzymes raised peak value after inoculating 3-5 days,but the change of activity of enzymes in resistant cotton cultivars were faster and higher than susceptible ones.The content of phenols in the roots and leave of 4 cotton cultivars also increased obviously after inoculation,but whether before or after inoculation the content of phenols in the roots and leave of resistant cotton cultivars were higher than susceptible ones.
