| 摘 要： | 利用营养液培养方法研究了外源SA对盐胁迫下黄瓜幼苗生长、叶绿素和类胡萝卜素含量、丙二醛及脯氨酸含量的影响。结果表明:外源SA能够显著提高盐胁迫下黄瓜幼苗的干鲜重、叶绿素和类胡萝卜素含量,显著减少丙二醛和脯氨酸的积累,从而减轻盐胁迫伤害,促进黄瓜植株生长。

| Abstract: | The effects of exogenous salicylic acid(SA)on growth,chlorophyll and carotenoid,malondialdehyde(MDA)and proline contents in the cucumber seedlings grown under salt stress were studied by hydroponic culture.The results showed that the dry and fresh weight,chlorophyll contentof salt-stressed cucumber were significantly enhanced with the application of SA,but the MDA and proline contents were significantly decreased and thus alleviated cucumber seedlings' salt injury and promoted its growth. |
