【摘要】 以4个生产中推广的花生品种白沙1016、远杂9102、豫花7号和豫花15号为材料,研究了干旱胁迫对花生形态及产量的影响。结果表明,在干旱胁迫下,4个参试品种的主茎高度、侧枝长、干物质质量、产量和经济系数均表现为降低,其中远杂9102主茎高度、单株干物质积累量分别为0.073 cm、1.24 g;产量和经济系数在4个参试品种中最高,分别为1 070.00 kg/hm2和0.18。远杂9102是4个品种中抗旱性最好的品种。更多还原

【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.更多还原
