摘要: 探究厦门市园林绿化乔木的叶功能性状及环境适应性,选取厦门市10种常用园林乔木进行研究,分别测定其叶片功能性状、生态化学计量特征和生理指标。结果表明,10种园林乔木的叶形指数(LI)、比叶面积(SLA)、叶干物质含量(LDMC)和叶含水量(LWC)、丙二醛(MDA)含量、游离脯氨酸(Pro)含量、过氧化氢酶(CAT)活性、单位质量叶碳含量(LCC)、单位质量叶氮含量(LNC)、碳氮比(C∶N)之间存在显著差异。相关性分析表明,LI与LWC呈极显著正相关,与LDMC呈极显著负相关,与LNC呈显著负相关;SLA与LWC、LNC、C∶N呈极显著正相关;MDA与LWC、C∶N呈极显著负相关;LCC与C∶N呈极显著正相关,与LNC呈极显著负相关;CAT与Pro呈显著负相关。主成分分析及隶属函数分析表明,10种常用园林乔木中的凤凰木(Delonix regia)、糖胶树(Alstonia scholaris)和榕树(Ficus microcarpa)在相同环境下表现出对厦门市较好的适应性。叶性策略分析发现凤凰木、糖胶树和榕树都属于“缓慢投资-收益型”生长策略(即叶片SLA和LDMC较高、LNC较低),更适合作为厦门市城市园林规划中的主要树种使用。

Abstract: To explore the leaf functional traits and environmental adaptability of garden greening trees in Xiamen City, 10 kinds of garden trees were selected for study, and their leaf functional traits, ecological stoichiometric characteristics and physiological indicators were determined respectively. The results showed that there were significant differences in leaf shape index (LI), specific leaf area (SLA), leaf dry matter content (LDMC) and leaf water content (LWC), malondialdehyde (MDA) content, free proline (Pro) content, catalase (CAT) activity, leaf carbon content per unit mass(LCC), leaf nitrogen content per unit mass(LNC), carbon to nitrogen ratio (C∶N) among 10 species of garden trees. Correlation analysis showed that LI was extremely significantly positively correlated with LWC, extremely significantly negatively correlated with LDMC, and negatively significantly correlated with LNC; SLA was extremely significantly positively correlated with LWC, LNC and C∶N; MDA was extremely significantly negatively correlated with LWC and C∶N; LCC was extremely significantly positively correlated with C∶N and extremely significantly negatively correlated with LNC; CAT was negatively significantly correlated with Pro. Principal component analysis and membership function analysis showed that Delonix regia, Alstonia scholaris and Ficus microcarpa among 10 common garden trees showed better adaptability to Xiamen City under the same environment. Leaf strategy analysis showed that Delonix regia, Alstonia scholaris and Ficus microcarpa belonged to the “slow investment-return” growth strategy (i.e. higher SLA and LDMC and lower LNC), which were more suitable for using as the main tree species in urban landscape planning of Xiamen City.
