河北草莓上发现春矮线虫病

Detection of A Spring Dwarf Disease of Strawberry in Hebei

1992～1994年对河北省草毒线虫病进行了普查。多次从保定市东郊草莓田内的丽红、九能早生品和上分离得到同一种滑刃线虫。经研究发现这种线虫与Christie（1942年）原始报道的Aphelenchoidesfragariae在形态上相同或相似。故将其鉴定为草莓芽线虫（Aphelenchoidesfragariae）。本又报道该线虫病害的症状及病原线虫的形态测计特征。

From 1992 to 1994, a general survey was made on nematode diseases on strawberry. An identical species of Aphelenchoides was isolated from the buds and leaflets of stunted strawberry plants (Lihong,Jiu neng zao sheng)collected from Baoding, Hebei Province. On the ground of its collformity with the original description of Aphelenchoides fragariae by Christie (1942), the nematode was identified here as Aphelenchoides fragariae,This paper reported the symptoms of the disease and morphometries of the nematode fothogen.
