Drought-induced Physiological Responses In Kidney Beans And Capsicum

The effects of water stress on seedling growth, stoma reaction, osmotic adjustment( the content of proline and soluble sugar) and SOD active in Kidney bean and Capsicum were studied. The results showed that the fresh weight and dry weight of seedling had adaptive capacity to soil humidity. With the water stress, stoma open rate declined, and the stoma of Kidney bean was more susceptible than the Capsicum's. The content of proline and soluble sugar increased , SOD active was high at initial water stress stage and low at end stage. In water stress, the soil humidity significantly negative correlated with the content of proline and soluble sugar.
