| 摘 要： | 选用 12个大豆品种 (系 ) ,于大豆开花结荚期 ,分别在正常供水与水分胁迫条件下 ,研究了与抗旱性有关的 4类生理指标 ,并结合大田试验结果进行了抗旱性综合分析。结果表明 ,叶片相对含水量 (RWC)、相对电导率、净光合速率 (Pn)与超氧化物歧化酶 (SOD)活性与大豆抗旱性(DC)密切相关 ,此 4项生理指标的隶属函数加权平均值 (D值 )与抗旱系数的相关系数达极显著水平 ,表明D值可用于大豆品种的抗旱性评价与分级。对大豆抗旱育种的方法进行了讨论

| Abstract: | In this paper,twelve soybean varieties was selected., four physiological indexes related to drought resistance in flowering poding stage were studied in both normal and drought conditions.The results were as follows:The weighed average of subordinate function(D) values of four physiological indexes-relative water content(RWC),relative conductivity,net photosynthesis velocity (Pn) and the activity of superoxide dismutase(SOD) and drought resistance of Soybean was positively significant(r=0 877 3,P<0 01).D value could be used to the evaluation of drought resistance for soybean varieties.At last,methods of soybean breeding for high yield and drought resistance were discussed. |
