| 摘 要： | 渗透胁迫下，小麦幼苗根系和叶片ABA，CaM水平提高，保护酶（SOD与POD）活性上升。结果初步表明：第2信号系统Ca^2 /CaM参与了干旱化学信号ABA的传递，引起小麦幼苗根系和叶片SOD，POD活性的升高。

| Abstract: | The effects of osmotic stress on physiological function of wheat seedlings were studied systemically. The level of ABA and CaM of wheat seedlings enhanced;the activities of SOD and POD rose under osmotic stress.The results showed:Ca 2+ /CaM participated in the transduction of the drought chemical signal (ABA) and at the same time led to the improvement of SOD and POD activities of wheat seedlings. |
