| 摘 要： | 在吉林省松原市建立了杨树对青杨天牛抗性的栽植实验区,调查了10个不同品系杨树的青杨天牛发生量,并对各杨树品系枝条的主要营养成分进行了分析。结果显示:各杨树品系间青杨天牛的发生量以及枝条中氨基酸含量之间的差异均极其显著;杨树品系青杨天牛的发生量与可溶性总糖及含水量之间有显著正相关关系(相关系数分别为0.737和0.684),但与全氮及蛋白态氮含量之间无显著相关关系(相关系数分别为-0.166和-0.100)。

| Abstract: | An experimental area of poplar was established in Songyuan of Jilin Province in 1999 for testing the resistance of different poplar stains to Saperda poplnea. Incidence of S. poplnea on ten poplar strains were investigated, and the main trophic component of branches of these poplar trees were measured and analyzed in April 2001. The results showed that there existed significant difference in population size of S. poplnea on different poplar strains, and the branches of these poplar strains have significant difference in nutrient component and content of amino acids. The population size of this pest had a significantly positive correlation with dissolvable total sugar and water content but had no significant correlation with content of total nitrogen and protein nitrogen. |
