近年、对不同抗感黄萎病棉花品种的还原糖、单宁含量和酯酶以及过氧化物酶活性进行了比较研究,初步明确了棉株体内诸种生化成分与品种抗黄萎病的相关关系,兹将主要结果简报如下 烘试的5个陆地棉品种分别为86-121(抗病品系,平均病指为6.90):冀合328(耐病品种;平均病指14.75):川2783(感病品系、平均病指34.67):盐棉48(感病品种,平均病指36.88);
In recent years, the reducing sugars, tannin content, esterase and peroxidase activities of different resistant varieties of Verticillium dahliae were compared, and the relationship between various biochemical components in cotton plants and the resistance to Verticillium wilt was preliminarily determined The main results of the briefing are as follows: The five upland cotton cultivars tested were 86-121 (resistant strain with an average disease index of 6.90): Jihe 328 (resistant variety; mean disease index: 14.75): Chuan 2783 Disease lines, the average disease means 34.67): salt cotton 48 (susceptible varieties, the average disease means 36.88);
