Quercus acutissima is a predominant tree species in the deciduous broad-leaved forest in *** in a large landscape area and can disperse in various ecology *** study onQuercus acutissima can provide valuable information about the genetic diversity level and geneticrelatedness on this important tree *** into the genetic structure also provides resourcesof a species with its current feature and future evolutionary *** genetic structure ofQuercus acutissima was investigated by randomly amplified polymorphic DNA(RAPD).TwelveRAPD markers were used to assess genetic diversity of408individuals from17provenancesenveloping most of the current distribution area of Quercus acutissima.A total of66amplificationproducts were detected,of which49bands(74.24%)were ***'s genetic diversity,0.2409,indicated a relatively high level of genetic variation in Quercus acutissima germplasm.
鳞毛蕨属Dryopteris Adanson隶属于鳞毛蕨科,是世界蕨类植物的大属之一,也是蕨类植物分类的疑难类群之一。中国是鳞毛蕨属植物的地理分布中心,但自《中国植物志》第五卷第一分册出版之后,对中国鳞毛蕨属植物的经典分类学研究无更多进展。本文对中国鳞毛蕨属植物进行分类学订正研究,确认中国产鳞毛蕨属植物的种类约150种,属下分为4个亚属,17个组。属下分类系统如下:奇羽亚属Subgenus I Pycnopteris(***)Ching
