Title: A study on main drought resistant index of land rice

The content of free proline and soluble sugar of leaves, membrane permeability of leaves cells, relative water content of tissue, lost water ratio of isolated leaves and root-shoot ratio can act as drought resistant index of land rice under water stress. These indexes can be used to comprehensively appraise drought resistance of these varieties by subordinative fuzzy function. Hejiang 5 is a weak resistant variety in all period, Donglu 1 is a strong resistant variety in all period and Tuiguang 1 is a strong resistant variety in pre-period and is a weak resistant variety in post-period.Read More
