Abstract

Changes in morphological indexes，chlorophyll mass fraction，malondialdehydel（MDA） molal concentration and protective enzyme activities of Hosta hybrida So Sweet，Aspidistra elatior Punctata，Speirantha gardenii with shading treatments of 50%，75%，90% and a control of 0% were studied using the subordination function method. Results showed that the morphological indexes of the three plants were significantly higher （P＜0.05） than the control. Indexes of H. hybrida So Sweet were greatest with 75% shading，but the indexes of A. elatiorPunctata and S. gardenii were largest with 90% shading. The mass fraction of chlorphyll a（Chl a） and chlorphyll b（Chl b） for shading treatments were significantly higher（P＜0.05） than the control and the increased range of S. gardenii was biggest. Chl a/Chl b was significantly lower （P＜0.05） than the control and the decreased range of S. gardenii was biggest. Malondialdehyde（MDA） molal concentration was significantly lower（P＜0.05）with shading treatments than the control. The changes of superoxide dismutase（SOD） activities of H. hybrida So Sweet decreased first and then increased，while those of A. elatior Punctata and S. gardenii gradually decreased. With increased shading，changes in peroxidase（POD） activities of H. hybrida So Sweet and A. elatior Punctata decreased to a certain degree and then increased. POD activities of S. gardenii decreased with 50% shading，but increased with 75% shading and then decreased. According to the subordination function method，shade tolerance of the three plants was in the order：Speirantha gardenii＞Aspidistra elatior Punctata＞Hosta hybrida So Sweet. ［Ch，3 fig. 3 tab. 22 ref.］
