辽宁西北部主要园林绿化树种叶片生长规律

摘要/Abstract

摘要： 采用标准化主轴和聚类分析方法,研究辽宁西北部主要树种叶片的比叶面积和异速生长规律。结果表明:种间叶片面积与生物量的共同斜率为1.052,其中46个树种斜率小于1.0,1个树种等于1.0,8个树种大于1.0;种间叶片含水量与生物量的共同斜率为1.052,其中42个树种斜率小于1.0,13个树种大于1.0。各树种比叶面积变化范围在48.83~276.52 cm²·g^-1,当欧氏距离为15时,可将树种划分为3类。辽宁西北部主要树种叶片生物量与面积、生物量与含水量之间总体呈等速生长,而各树种的异速生长指数却明显不同。树种比叶面积相对较低是其适应贫瘠环境的自然结果。因此,在干旱半干旱地区城市绿化和造林中,应选择比叶面积较小的树种。

Abstract: In this paper, the specific leaf area and allometry of the main landscaping tree species in northwest Liaoning Province were estimated using the standardized major axis estimation and cluster analysis. The results showed that the common slope between leaf area and biomass of the tree species was 1.052. Among all 55 tree species, the slope of 46 tree species was less than 1.0, of 1 equaled to 1.0, and of 8 was large than 1.0. The common slope between leaf water content and biomass was 1.052, in all the 55 tree species, the slope of 42 tree species was less than 1.0, and of 13 was larger than 1.0. Specific leaf area ranged from 48.83 to 276.52 cm²·g^-1. The tree species could be divided into 3 groups when the euclidean distance was 15. These results indicated that there were the isometric relationships among leaf biomass and leaf area and water content in all the 55 tree species in northwest Liaoning Province. However, allometry index was different among the tree species. Specific leaf area of the tree species in northwest Liaoning Province was low since the tree species adapted the severe environment. It was suggested to select the tree species with low specific leaf area as the landscaping tree species in arid and semiarid area.
