我省杉木无性系选育研究已见成效,很多优良无性系将转入推广造林。杉木炭疸病是杉木的严重病害之一,在推广其优良无性系之前,对其抗病性进行调查和测定,是个不可忽视的问题。为了探讨杉木无性系抗病能力的差异,1987年,我们对本所在靖县排牙山林场消水坑无性系测定林中的13个无性系,进行了测定,现整理如下。一、材料与方法供试菌种为当年3～4月份从杉木感病针叶上分离新鲜菌种,经纯化繁殖所得。供试无性系有:1.靖县排牙山林场种子园优良半同胞家系转化的8个无性系,代号
Cunninghamia lanceolata clonal selection research has been successful in our province, many excellent clones will be transferred to promote afforestation. Cunninghamia lanceolata is one of the serious diseases of Chinese fir. Before the promotion of its excellent clones, the investigation and determination of its disease resistance is a problem that can not be neglected. In order to explore the differences in disease resistance of Chinese fir clones, we measured the 13 clones in the clinker clinker of the Paiyan Mountain Forest Farm in 1987 in Jingyaxian County of Jing County. The results are summarized as follows. First, the material and methods for the test species for the year from March to April Separation of fresh strains of Sophora japonica leaves, the purification and propagation derived. Clones for the test are: 1. Jingxian Pai Yayanshanchang seed orchard semi-sib family conversion of eight clones, code
