不同茶树品种其叶片对茶轮斑病的感染是有差异的。无性系品种31/11和303/199受害程度(病斑直径分别为1.8和2.2mm)显著低于品种303/999和303/577的(病斑直径分别为6.0和9.0mm)(p=0.05)。通过对茶树品种有关感抗因子的调查表明成熟叶片茶多酚总量起主要作用。不同茶树品种的茶多酚总量不同,茶轮斑病的感染程度与其含量呈显著负相关(r=-0.84,p=0.05)水溶性碳水化合物含量以及成熟叶片细胞液 pH 值与病菌危害程度无关。
There are differences in the infection of tea leaf spot between different tea tree varieties. The damage degree of clones 31/11 and 303/199 (lesion diameter of 1.8 and 2.2 mm, respectively) was significantly lower than that of cultivars 303/999 and 303/577 (lesion diameters 6.0 and 9.0 mm, respectively) (p = 0.05 ). The investigation of the resistance factors of the tea varieties showed that the total amount of tea polyphenols in the mature leaves played a major role. The total amount of tea polyphenols in different tea varieties was different. The infection level of tea leaf spot disease had a significant negative correlation with its content (r = -0.84, p = 0.05), the content of water-soluble carbohydrates, Nothing to do
