摘要
对川南地区常见的12种藤本植物叶片特征进行研究的结果表明:园林中藤本植物叶性状存在较大差异,且不同指标变异程度不同;部分性状相关性显著(P<0.05),比叶面积随叶片干重的增加而减小,随单位鲜重含水量的增加而增加,单位鲜重含水量、鲜重和叶面积能较好地表征不同种类比叶面积的变化(R2=0.886,P<0.01);叶干重、叶鲜重与叶面积呈正相关;叶绿素含量与其它叶性状的相关性不显著。
The useful 12 species of landscape lianas in south Sichuan were studied. The results showed that leaf traits were various and some index with large variation. The significant correlations were found between some traits ( P 〈 0. 05 ), specific leaf area (SLA) increased as the dry weight lowered and the water content per unit weight increased, the water content per unit weight, leaf area and fresh weight greatly explained the variation of SLA ( R2 = 0. 886, P 〈 0. 01 ). dry weight were positively correlated with fresh weight and leaf area. There was no significant correlation between leaf chlorophyll content and all other leaf traits. According to clustering analysis, The lianas species was divided into different class for improving plant disposition in the garden.
