摘要：以1年生107杨为研究材料,对树体干部电容和叶片电容的内在生理学基础进行研究。结果表明:树木叶片电容与单位质量叶片离子外渗液电导率、叶片细胞离子外渗百分率及叶片绝对含水率呈显著的正相关关系,与单位质量叶片总电导率呈显著的负相关关系;树木的干部电容与胸径、树皮相对膨胀度存在显著的正相关关系;在此基础上提出树木干部“单位电容”的概念,健康树木与衰弱树木的干部电容和单位电容存在明显差异。
The relationship between leaf and stem capacitance of Populus × Neva＇ and its physiological index was studied. The results showed that the leaf capacitance had significant positive correlations with leaf exosmosis electroconductivity, exosmosis percentage and leaf absolute moisture content, had significant negative correlations with leaf electrolyte electroconductivity and had no correlations with leaf relative water content （RWC） ; the stem capacitance had significant positive correlations with DBH（diameter at breast height） and bark relative turgidity （RT）. The conception of ＇unit capacitance＇ was proposed. There were evident differences between health and debility trees in stem capacitance and unit capacitance. So the research of the leaf, stem and unit capacitance would provide a theoretical basis for the quantitative assessment of the degree of damage and lack of water of trees, the ability of disease-resistance, tree vigor and stands growth condition.
