| 摘 要： | 以1a生组培琴叶榕盆栽苗为试材,控水模拟不同土壤水分状况,探讨不同程度干旱胁迫对琴叶榕叶片生理特性的影响。结果表明:随着干旱胁迫程度的提高,琴叶榕株高、净光合速率、蒸腾速率和叶绿素含量均呈现下降趋势;脯氨酸含量、丙二醛(MDA)含量都随着干旱胁迫程度的加强而显著升高;POD活性随干旱胁迫的加强而升高;SOD活性在轻度和中度干旱下上升,在严重干旱胁迫时反而下降。

| Abstract: | Taking one year-old potted tissue culture plantlet of Ficus lyrata as material,physilolgical characteristics of Ficus lyrat leaves under different soil water condition were analyzed.The results showed that plant height,net photosynthetic rate,chlorophyll content of leaves reduced with increasing drought stress.At the same time,proline content and malondialdehyde(MDA) concentrations significantly incredsed,and POD activity increased as well.SOD activity increased under the mild and moderate drought stress,bu... |
