Abstract

Studying ecological stoichiometry is an approach to understand the response of plants to environmental change. To determine management patterns and their effect on ecological stoichiometry with Phyllostachys edulis, an experiment was conducted by respective sampling to observe the effects of extensive and intensive management patterns on ecological stoichiometry with Phyllostachys edulis leaves for a stand in subtropical China. One-way analysis of variance （ANOVA） and least significant difference （LSD） tests were used to test the statistical significance of differences between two management types of plantations. Results showed that, compared to extensive management, intensive management significantly increased C and P content of leaves from both 1-year-old and 3-year-old bamboo （P＜0.05）, as well as N content from 3-year-old bamboo （P＜0.05）. Management level significantly affected C, N, and P content （P＜0.01） as well as C ∶ N, C ∶ P, and N ∶ P ratios of leaves （P＜0.05）; Phyllostachys edulis age also had a significant effect on C and P content as well as the C ∶ N and C ∶ P ratios of leaves （P＜0.01）. Meanwhile, the interaction of management level and age only significantly influenced N content and the C ∶ N ratio of leaves （P＜0.01）. Findings indicated that with the two management patterns, N limited Phyllostachys edulis productivity, and that increasing N by fertilization would facilitate growth thereby contributing to more accumulation of biological carbon.［Ch, 2 fig. 4 tab. 26 ref.］
