种子引发对盐胁迫条件下桔梗种子萌发及幼苗生长的影响OACSTPCD
Effects of Seed Priming on Germination of Platycodon grandiflorum Seeds and Seedling Growth under Salt Stress
为探索引发对盐胁迫条件下桔梗种子萌发和幼苗生长的生理效应,增强桔梗苗期的耐盐能力,本试验进行以氯化钠(NaCl)、氯化钙(CaCl2)、赤霉素(GA)为主的引发剂筛选及引发剂对桔梗种子萌发特性、幼苗生长和生理特性影响的研究.结果如下:1％ NaCl、1％ CaCl2、1％ NaCl+1％ CaCl2、1％ NaCl+1％ CaCl2+750 mg/L GA均能提高种子发芽率、幼苗干物质积累,其中1％ NaCl+1％ CaCl2+750 mg/L …查看全部>>
In order to explore seed germination characteristics and seedling growth of Platycodon grandiflorum under salt stress after seed priming,the priming experiments were conducted with NaCl,CaCl2 and GA,and the seed germination,seedling growth and physiological characteristics were compared between with seed priming and without priming.The results were as follows:the priming solutions of 1％ NaCl,1％ CaCl2,1 ％ NaCl + 1％ CaCl2 and 1％ NaCl + 1％ CaCl2 + 750 mg/L GA c…查看全部>>
