摘　　要：盐胁迫会影响种子的萌发以及后期产量的形成,研究如何经济有效地缓解盐胁迫的危害对于提高作物的产量与品质起着具有非常重要的作用。以鲁麦21和济南17两个小麦品种为例,以水作为引发剂对小麦种子进行引发处理,设置对比不同引发时间,和保湿时间这两个影响因素,形成不同条件的处理组合。通过对幼苗进行测定与分析,探索在哪种引发处理条件下小麦有更好的抵抗盐胁迫的能力。结果表明:适宜的水引发处理可以明显提高盐胁迫下小麦种子活力。对于鲁麦21,和济南17这两个品种来说,在水引发10 min,结合保湿12 h时具有较好的缓解盐胁迫效果。Salt stress affects the germination of wheat seeds and the formation of yield.Studying how to effectively alleviate the pressure of slat stress is a very important role in improving the yield and quality of wheat.In this experiment,two wheat varieties,Lumai 21 and Jinan 17,were chosen as examples.The wheat seeds were treated with water as initiator,and the initiation time and moisturizing time were set to form the treatment combination under different conditions.Through the measurement and analysis of the morphological and physiological indicators of the seedlings,this experiment explored in which priming treatment conditions wheat had better resistance to salt stress.The results of this experiment indicated that the suitable water priming treatment could significantly improve wheat seed vigor under salt stress.For Lumai 21 and Jinan 17,the salt stress is better alleviated when the water is triggered for 10min and kept for 12h.
