| Abstract: | Sensitivity to drought stress varied among different peanut cultivars.This paper analyzed the influence of drought stress which changes of criteria for peanut morphology and yield,using four peanut cultivars Baisha1016,Yuanza9102,YuhuaNo.7,Yuahua No.15.The results showed that under drought stress,mainstem height,length of lateral branches,dry matter accumulation,yield and economic coefficients all declined in different degrees.The degree of change on peanut morphological characteristics and yield differed among the four peanut cultivars.In general,the effects on Yuanza9102 were less than others;mainstem height and dry matter accumulation had declined 0.073cm and 1.28g per plant,respectively;yield and economic coefficients of Yuanza9102 were higher than other cultivers with 1070.00kg/ha and 0.18,espectively.The above results indicated that,the best drought resistance peanut cultivar was Yuanza 9102. |
