摘要
选用皖豆15号大豆种子为试验材料,钼酸铵溶液为引发剂,进行浸种保湿引发,钼酸铵溶液浓度分别为1%、2%和4%,浸种时间均为10 min,保湿时间分别为6、12 h和24 h,研究不同引发处理对大豆种子活力的影响,探讨钼酸铵溶液引发的适宜方法。结果表明:1%钼酸铵溶液浸种10 min保湿6 h的引发处理效果最好,其幼苗生长测定的主要活力指标和萌发种子胚根的POD、CAT活性,均显著或极显著优于干种子和双蒸水对照,SOD活性极显著高于干种子对照。
Wandou No.15 was used as materials and ammonium molybdate solution as the seed priming.The concentrations of ammonium molybdate solution were 1%,2% and 4%,the soaking time were all 10 minutes and the moisturizing time were 6 h,12 h and 24 h.studied the effect of different treatments on soybean seed vigor and explored the most suitable way of ammonium molybdate solution priming.The results showed that the effect of ammonium molybdate concentration 1% soaked 10 min and moisturized 6 h was the most treatment.The major seed vigor index and POD,CAT activities in radical of seedling growth testing were obviously or more higher than the control treatment of dry seeds and dH2O and SOD activity increased more significantly than the control treatment of dry seeds.
