摘要
树叶是植物进行光合作用与呼吸作用的重要器官，叶面积与其生物量是树木参与生理过程的重要参数，直接影响树木的生物学结构。研究通过对昆明地区干湿两季与不同叶龄的桉叶采样与测量，利用Image J软件分别对干季和湿季的叶面积与生物量进行对比分析，结果表明：湿季和干季对桉叶面积的影响存在较大差异，尤其是湿季对一年生桉叶面积的影响较大；生物量对干季与湿季的响应也呈现出明显的不同。该研究可为桉树的生理特征与物候规律提供理论参考。
Abstract
With the function of photosynthesis respiration , leaves are vital organs .The area and biomass of leaves are important parameters involved in the physiological process in trees and directly affects the biological structure of trees.The samples of eucalyptus leafs were studied which have different ages in dry and wet season in Kunming .Image J software was used to compare and analyze leaf area and biomass in dry and wet season .The re-sult shows that the climate has an important effect on the eucalyptus leafs ’ area, especially the wet season .In addi-tion , biomass also shows obvious difference according to the change between wet season and dry season .The study can be used as theoretical reference for physiological characteristics of eucalyptus and the laws of phenology .
