| Abstract: |
| The study on the response to water stress and drought resistance estimate of 27 varieties at germination stage was conducted through adopting PEG solution simulated soil drought treatment.The results showed that the germinating vigor and germinating rate,the growth rate of embryo bud and root,and the transformation percentage of stored substance were all decreased under drought stress.The drought resistance of every variety was different,and higher drought-resistant varieties kept higher vigor of germination and rooting ratio.There was significant difference on the "a" value of every indexes of every peanut variety under 17.5% PEG water stress,and it can be used as the concentration index of drought-resistance identification. |
