摘    要:50、75、100、150 mg/L JA处理苹果叶片表皮,使开放气孔的气孔开度分别减小27.4%、37.5%、56.9%和63.8%,使关闭后的气孔在光下开放时气孔开度分别减小15%、18%、28.8%、52.5%、61.3%;处理植株后干旱胁迫,叶片相对电导率分别降低15%、18%、31%、58%,脯氨酸含量分别提高0.09%、0.40%、0.42%、0.54 ng/gFW,可溶性糖含量分别提高1.89%、2.53%、3.80%、5.06%。25 mg/L JA处理与对照均无显著差别。JA的作用表现出明显的浓度效应。

关 键 词:茉莉酸  苹果  气孔  抗旱性

Abstract:Epidermis of leaf treated with 50,75,100,150 mg/L Jasmonic acid(JA) significantly promoted closing and inhibit ed opening of stomata.When pants treated by JA for 4 days,the content of leaf soluble sugar and proline were also increased,while relative electricity decreased.Lower concentration at 25 mg/L had no obvious differences compared to the control.The results indicated that JA treatment could enhance drought tolerance of young apple trees and the effect was related to the concentration used.
Keywords:Jasmonic acid Apple Stomata Drought-tolerance
