摘要： <正>松针褐斑病(Lecanosticta acicola)是湿地松(Pinus elliottii)、火炬松(P.taeda)和黑松(P.tunbergii)的重要病害,防治比较困难。从1982年开始采用对比法在重病林分中选择湿地松抗病优树122株,嫁接繁殖建立抗病湿地松采穗圃2.7ha,并用自然感染法和人工接种法对繁殖成的122个优树无性系进行抗病性测定和筛选,其中约有1/2的无性系表现具极高的抗病性。利用筛选出的抗病无性系建成湿地松无性系抗病种子园4ha。

Abstract: Brown spot disease is one of important diseases on Poms elliuttu,P. taeda,P. tunbergti in south China. Resistance selection of slash pine to brown spot disease has been made since 1982. 122 disease resistance phenotypes of slash pine were selected in heavy infected plantations in Fujian and Jiangxi provinces and 3 ha disease resistance cutting orchards were established by grafting with those phenotypes. Further screening by natural infection and artificial inoculation were conducted and 62 clones with high resistance were obtained. A seed orchard about 4 ha with disease resistance clones of slash pine was established in Fujian province.
