摘要

采用冗余分析(RDA)等方法,对12个大叶梅个体环境因子与生物性状间关系进行了探讨,对性状在不同环境下的变化模式进行了描述。结果表明:地衣性状在个体内表现了一定程度的稳定性、在总体上表现出较大程度的变异性;无论是个体内还是总体中,菌丝直径都表现了最大的稳定性。冗余分析表明,湿度与环境因子光照呈显著负相关,与菌丝直径呈最大正相关,与生物变量髓层厚度呈最大负相关;海拔与假根密度呈最大正相关,与下皮层厚度呈最大负相关。藻孢层能较好地反映环境的综合变化,黑茶渍素含量能对环境光照条件作出较好地响应。不同生境下大叶梅在各功能部分的投资比例值得深入研究,在揭示地衣对环境变化响应模式方面具有更大意义。

Abstract

The relationships between biological characters of Parmotrema tinctorum in twelve individuals and their environmental factors were analyzed by the methods including the Redundancy analysis (CDA),and the variation patterns of the characters in different habitats were described.The results showed that the biological characters manifested a stability to a certain extent within individual,but they holistically had a great variability,and the anatomical character hyphae diameter had the minimum variation coefficients not only within individuals,but also as a whole.Redundancy analysis showed that the humidity had a significant negative correlation with illumination (an environment factor),the most-positive one with hyphae diameter,and the most-negative one with medulla width (a biological index).While the altitude had the most-positive correlation with rhizoid density and the most-negative one with lower cortex width.The amount of algae layer could reflect the comprehensive environment change very well,while the content of atranorine in organism could response to illumination of certain habitat sensitively.The material investment among different function parts of lichen thallus,which is of great importance in revealing the response model of lichens to environment change,deserves to investigate deeply.
