不同光照条件下对6种室内垂吊花卉的形态和生长适应性变化进行了研究,测定了叶长、叶宽、叶面积、比叶重和气孔密度等指标.结果表明,叶长、叶宽、叶面积均随光照强度减弱而增加,但比叶重、气孔密度随光照强度减弱而减少.根据各指标可塑性指数和方差分析可知,鸭跖草、吊竹梅、金心吊兰耐荫能力较强;而常春藤、袋鼠吊兰、皱叶冷水花耐荫能力相对较弱.

Morphological adaptability and changes of growth characteristics of six hanging plants were studied under shading treatment by measuring leaf length, leaf width, leaf area, mass per area of leaf and stomata density. The results showed that the leaf length, leaf width and leaf area increased but mass per area of leaf and stomata density decreased as the shading intensity weakened. The Commelina communis, Zebrina pendula and Chlorophytum comosum have higher shade tolerance than that of Hedera helix, Nematanthua cheerio and Pilea mollis according to the plasticity index and variance analysis.
