| Abstract: | Using paraffin sectioning technology,the drought resistance structure of leaf collected from 12 varieties of walnut at Weibei Base(Huanglong) of Shaanxi Provincial Walnut Research and Development Center,was studied and analyzed carefully,and the results shows that the thickness of upper-epidermis,ratio of palisade tissue to mesophylls and thickness of vascular bundle are the better indexes of drought resistance.Comprehensive analysis using membership function method indicated that the drought resistance ord... |
