四川省野生荞麦资源的调查与收集
Investigation and Collection of Wild Buckwheat Resources in Sichuan Province of China
摘要
Abstract
Sichuan's complex and diverse terrain has nurtured rich plant resources.To clarify the geographic distribution and population size of buckwheat germplasm resources,in 2022-2023,the Wild Buckwheat Resource Survey Team(College of Life Sciences,Sichuan Agricultural University)conducted a survey and collection of resources in Sichuan province,China,mainly for the northwest and southwest mountains,and the Chengdu Plain,Sichuan Hills,including 30 counties(districts).We collected a total of 156 wild plant germplasm resources of the genus Fagopyrum[103 F cymosum(Trevir.)Meisn.,23 F tataricum subsp.potanini,3 F esculentum subsp.ancestrale,17 F.gracilipes(Hemsl.)Dammer.ex Diels,5 F leptopodum(Diels)Hedberg,2 F.caudatum(Sam.)A.J.Li,2 F.macrocarpum Ohsako et Ohnishi,1 F rubifolium Ohsako et Ohnishi].The northwest of Sichuan province was found with the richest wild buckwheat species.F.cymosum(Trevir.)Meisn.is the wild buckwheat with the largest distribution,mainly distributed in the hilly areas of central Sichuan.The distribution of F.macrocarpum and F.rubifolium has extremely obvious regionality.There is a wide range of genetic variation between wild buckwheat resources in different habitats.Statistics on the companion plants of wild buckwheat resources show that Urtica fissa E.Pritz.and Bidens pilosa L.are the most numerous companion plants.This survey and collection not only enriches the buckwheat resource germplasm bank,but also lays the foundation for studying the distribution patterns of wild buckwheat and formulating protection measures.关键词
