摘要:<正> The dynamic changes in membrane permeability, activities of disease-related enzymes, and contents of pathogenesis-relevant chemical compounds and photosynthetic pigments in root cells of three watermelon cultivars were studied after inoculation with Fusarium oxysporum f. sp. niveum at seedling stage. The results showed that the capacity of self-regulating and returning to normal status of cultivar Kelunsheng (resistant) was greater than that of a susceptible cultivar, Zaohua, in terms of malonaldehyde (MDA) content, relative conductivity, and activity of superoxide dismutase (SOD) and catalase (CAT). The resistant cultivar maintained a higher activity of dehydrogenase, higher content of vitamin C(Vc) , and relatively lower content of soluble sugar than the susceptible cultivar. The content of soluble protein was higher in the resistant cultivar than that in the susceptible one at day 1 after inoculation. The capacities of the resistant cultivar to inhibit chlorophyll deterioration and maintain a higher
