| 摘 要： | 以新棉33b光子为材料,经赤霉素、缩节胺、维生素b6、萘乙酸、水杨酸、高分子吸水树脂、海藻酸钾和清水浸种、晾干处理,在0、0.2%、0.4%、0.6% nacl胁迫下进行发芽试验,测其发芽势、发芽率。至发芽12 d后,测定棉苗主根长、株高及根、茎和子叶的干重。结果表明：150 mg/l 缩节胺、50 mg/l赤霉素、20 mg/l维生素b6和25 mg/l萘乙酸处理对棉花种子发芽和幼苗生长均具有明显的促进作用,其中以25 mg/l萘乙酸处理效果最好。50 mg/l 赤霉素处理明显提高了株高,150 mg/l 缩节胺和20 mg/l维生素b6处理的棉花种子活力、抗盐性明显提高。
