Sexual Systems and Ecological Links of Wood Plants in Kunyu Mountains
摘要
Abstract
Plant sexual system related with ecosystem composition and population evolution is affected by multiple ecological factors. In order to analyze the correlation between the sexual system distribution and the ecology of the plants in Kunyu Mountains,835 species of vascular plants at different altitudes in Kunyu Mountains were investigated,and their floral characteristics,fruit type,life-form and pollination characteristics were observed and recorded in detail. Correlations between the above characteristics and the plant sexual system were analyzed by chi-square test. The sexual system composition of the plants in Kunyu Mountains was compared with other regional plant communities. Factors affecting the sexual system composition and reproduction strategies of the plants were also investigated. The results showed the percent of hermaphrodite plants, monoecious plants and dioecious plants in Kunyu Mountains was 79. 2%, 11. 3% and 9. 5% respectively, and the proportion of hermaphrodites was higher than that of temperate forests in North America, this phenomenon was related to phylogeny. The floral characteristics,pollination patterns and fruit types were significantly correlated to the sexual system.关键词
