摘要:

研究了不同程度干旱胁迫下,金银花、地瓜藤、洋常春藤等3种常绿藤本地被植物形态、生理特性的变化。结果表明:水分胁迫后,三种藤本植物叶片的质膜透性均有上升,其中金银花增幅最小,过氧化物酶(POD)先略上升后下降,且金银花、地瓜藤维持较高活性,调节物质脯氨酸、可溶性糖含量增加,金银花的含量增幅最大,利用模糊数学隶属函数综合分析,得出抗旱性强弱顺序:金银花>地瓜藤>洋常春藤。

Abstract:

Under different drought stresses, changes of the morphological, physiological characteristics are studied on three kinds vine of evergreen ground cover plants: Lonicera japonica, Ficus tikoua and Hedea helix. The results showed that the drought stress treatment could increase membrane permeability of leaf cells. And Lonicera japonica had the smallest increace. The activities of POD increased first and then declined, which in Lonicera japonica and Ficus tikoua were relatively high. The content of praline, soluble sugar in the leaves of three evergreen lianas increased, and also Lonicera japonica had the most. Finally, It was concluded that the drought - resistant ability of three tested species decreased in the following order: Lonicera japonica, Ficus tikoua, Hedea helix by a comprehensive analysis of fuzzy membership functions.
