摘要
对贵州地区翦股颖属野生植物资源的分布、生境、花果期及主要性状等进行了野外调查和室内鉴定,并对其资源品质和坪用性状进行了对比评价。结果表明,贵州省境内分布有6种翦股颖属天然禾本科植物,它们分别是匍茎翦股颖(A.stolonifera)、细弱翦股颖(Agrostistenuis)、小糠草(A.matsumurae)、华北翦股颖(A.clavata)、多花翦股颖(A.myriantha)、短柄翦股颖(Agrostisbrevipes)。通过对这6种资源与引进品种Cato和Putter的性状比较以及9分制评定法评比说明:Cato成品品质优于野生材料,但Putter成坪品质次于野生材料,各野生材料在其性状特性上还表现出多样性和变异性。
The field investigation and indoor identification were conducted on distribution,surrounding,flower and fruit period and main characters of wild bentgrass resources in Guizhou province.The resource quality and lawn characters have been evaluated comparatively.The results showed that 6 wild grass plants of bentgrass were distributed in Guizhou province.They were as follows:creeping bentgrass (A.stolonifera),slight bentgrass(Agrostis tenuis),bentgrass(A.matsumurae),stick bentgrass(A.clavata),mangflower bentgrass(A.myriantha)and short handle bentgrass(Agrostis brevipes).The comparative studies were made between 6 native resources and 2 import varieties(Cato and Putter)and their characters were scored by 9 systematic evaluation.It was demonstrated that the lawn guality.of Cato was prior to wild material,but Putter was inferior to wild material.Each material expressed diversity and variation.
