Abstract:
At the most serious disease period under the field condition, four biochemical traits in leaves of cotton with different resistance to Verticillium dahliae and the traits between infected and intact plants in the same cultivars were studied.The results indicated that the disease-resistant cultivars displayed weak SOD and POD activities, low membrane lipid peroxidation and high soluble protein content.The sensitive cultivars showed the contrary results.In the same disease-senstitive cultivars, as compared with the intact plants, the infected plants showed higher POD activities and membrane lipid peroxidation.On the average, SOD activity was higher and soluble protein content was lower in intact plants.The results were also indicated that the rised extent of POD activities were large whatever in resistent or susceptible cultivars.The change extent of SOD activities in resistant cuitivars was gently, but in susceptible cultivars largely.
