Six melon species were used as experiment materials to measure their plant height stress index(PHSI), dry matter stress index(DMSI), WSD, RWC, bound water content, tissue water content, random water content, electrolyte transudation ratio, injury ratio under drought treatment and water retaining capacity of excised leaves. With these indexes, the drought resistance of different species was evaluated. The results showed that PHSI, DMSI, WSD, electrolyte transudation ratio and injury ratio under drought treatment could be used to appraise the drought resistance of melon species at seedling stage. |
