Comparative Study on Drought Resistance of 14 Trifolium repens Varieties
Through the potted and water-controlling experiments in greenhouse,the author studied the changes in wilting coefficient,withered leaf rate,leaf relative water content,leaf water content and leaf chlorophyll content of 14 Trifolium repens varieties under drought stress,and comprehensively compared the drought resistance of these varieties by using membership function method.The results indicated that Haifa had the strongest drought resistance among 14 varieties,and Prop had the worst drought resistance.The physiological drought resistance of 14 Trifolium repens varieties could be arranged as follows:Haifa ＞ Koala ＞ Rivendel ＞ Zapican ＞ Synergy ＞ Pepsi ＞ Ladino ＞ Klondike ＞ Grassland Huia ＞ Dutch ＞ Milkanova ＞ Super Huia ＞ Harmony ＞ Prop.
