摘要
近10年来对长白山野生草莓资源进行了较深入考察,共收集到野生资源20份。对其植物分类学性状进行观察记载、对比分析和分类研究,鉴定它们分属于两种倍性的3个种,即二倍体种东北草莓(Fragaria mandschurica Staudt)、四倍体种东方草莓(F.orientals Lozinsk.)和伞房草莓(F.corymbosa Loz-insk.),确认前人报道的长白山区分布有东方草莓的一个变种———绿叶东方草莓[F.orientalisvar.concolor(Kitag.)Liou et C.Y.Li]实际为伞房草莓。首次报道长白山分布有伞房草莓。
The wild strawberry germplasm resources are widely distributed in Changbai Mountains. The strawberry gemplasm resources in Changbai Mountains were investigated and totally 20 wild strawberry genotypes had been collected in recent 10 years. Their taxonomic characters were observed and described, and their classification was studied by comparison. These wild strawberries are classified into 3 species according to the study, which are diploid Fragaria mandschurica Staudt, tetraploid F. orientalis Lozinsk. and F. corymbosa Lozinsk. F. orientalis var. concolor distributed in Changbai Mountains, which was regarded as the variety of F. orientalis Lozinsk. before, was denied according to the present study and it was identified as F. corymbosa Lozinsk. This is the first report that F. corymbosa Lozinsk. is distributed in Changbai Mountains.
