摘要:
?以田间劣变抗性品种湘豆3号和不抗品种宁镇1号为试材，采用盆栽方式，通过模拟发生田间劣变的逆境，研究了高温高湿胁迫[40℃/30℃、RH95%~100%/70%、10 h/14 h（白天/黑夜）\]对春大豆生理成熟期豆荚和茎叶生长量及种子活力的影响。结果表明：短时间（＜24 h）的高温高湿胁迫对2个大豆品种豆荚和茎叶的生长量影响不明显，胁迫48 h后，不抗品种宁镇1号豆荚和茎叶生长受抑制程度明显大于抗性品种湘豆3号；与对照相比，高温高湿胁迫后2个大豆品种的发芽势、发芽率、简易活力指数以及脱氢酶和酸性磷酸酶活性均呈下降趋势，并随胁迫时间的延长下降幅度增大，在各个胁迫时间点，不抗品种宁镇1号各测试指标的降幅均显著大于抗性品种湘豆3号。
Abstract:
?Pre-harvest seed deterioration resistant soybean cv. Xiangdou 3 and preharvest seed deteriorationsensitive soybean cv. Ningzhen 1 were used to study the effect of high temperature and high humidity stress(40℃/30℃,100%/70% humidity(RH),and 10 h/14 h cycle(light/dark)for 5,10,16,24,48,96 and 168 h,respectively)on plant growth and seed vigor indexes of spring soybean at physiological maturity stage.The results showed that pod and stem leaf mass growth of Xiangdou 3 and Ningzhen 1 had no significant difference at the short time(<24 h)stress,while,when the stress time exceeded 48 h,the growth of pod and stem leaf of Ningzhen 1 were restrained more serious than Xiangdou 3.The germination energy,germination percentage,simple vigor index,dehydrogenase activity and acid phosphatase activity of Xiangdou 3 and Ningzhen 1,compared with control,were reduced with high temperature and high humidity stress,and the reduce extent increased with the strees time elongation,on the whole,the tested indexes of preharvest seed deteriorationsensitive soybean cv. Ningzhen 1 were reduced more seriously than those of preharvest seed deteriorationresistant soybean cv. Xiangdou 3.
