【摘要】 对樟树黄化病发病程度与树皮电阻值、枝条含水量之间的关系进行了研究。结果表明:黄化病发生程度与树皮电阻值呈正相关;与树皮含水率呈负相关;树皮电阻值与含水量呈负相关。该研究揭示了樟树黄化病的发生发展机理,可用树皮电阻值取代树皮含水量,测定树木生长势或病情,从而简化测定程序。更多还原

【Abstract】 The camphor tree yellow is the most common disease in the urban environment at present. The physiological characteristic of the camphor tree such as moisture content and electric resistance of peel,timber material were analyzed and the photosynthesis with different disease index was studied in this thesis. The results showed: there was positive relation between the disparity of elect resistance of bark and disease index and negative relation between the moisture content of the bark and disease index. The photosynthesis rate was sharply decreased with disease index.更多还原
