| 摘 要： | 从松针褐斑病（Ｌｅｃａｎｏｓｔｉｃｔａ ａｃｉｃｏｌａ）重病林分中选出３６个湿地松（Ｐｉｎｕｓ ｅｌｌｉｏｔｔｉｉ）抗病表现型优树无性系，用人工喷洒病菌孢子液接种法对其进行抗病测定，结果表明，有２２个是高度抗病的。与用松针褐斑病产生的毒素粗提液处理上述无性系的离体针叶进行抗病性测定的结果基本一致，相关系数为０．８０。

| Abstract: | disease-resistant phenotype clones of slash pine selected from seriously infected plantations in Jiangxi province were tested by artificial inoculation with Lecanosticta acicola. The resultsshowed that 22 of the 36 clones are highly resistant to brown-spot disease. The resistance of theseclones was also tested by treating needles in vitro with crude metabolic toxin extracted from brown-spotfungus culture. The results were basically in agreemeat with that obtained by artificial inoculation (r =0. 80). |
