【摘要】 通过测定水分胁迫下棉花幼苗长度、根系活力、过氧化物酶 (POD)活性、过氧化氢酶(CAT)活性、脯氨酸 (Pro)含量等指标 ,研究了Ca2 +和GA浸种对水分胁迫下棉花幼苗生长的影响 ,结果表明 :Ca2 +和GA混合后对水分胁迫下棉花幼苗长度、根系活力、POD活性、CAT活性及Pro含量均有显著影响 ,其中 5mmol/LCaCl2 与 1mg/LGA混合效果最佳 ,而Ca2 +和GA单独处理对这些指标的影响效果弱于其互作效应。更多还原

【Abstract】 The effects of Ca 2+—GA soaking seed on seedlings growth under water-stress by measuring five indexers of the length of seedling, the vigor of root system, the activity of POD,the activity of CAT and the content of Pro. The result shows that Ca 2+—GA mixture solution had significant effect on five indexes above,in which,and the result of Ca 2+(5 mmol/L)—GA (1 mg/L) mixture solution was the best.更多还原
