国外生态经济树种沙棘引种驯化及早期评价

Introduction and Domestication as Well as Early Evaluation of Hippophae rhamnoides of Foreign Ecological and Economic Species

为丰富我国高寒地区生态经济林树种遗传多样性,促进林业生态体系和产业体系建设,遵循供种区与引种区环境条件相似的原则,根据引种区气候、土壤、植被分布、地形地貌及地理位置等主要环境条件,确定与之相适宜俄罗斯为供种区。以6个俄罗斯大果沙棘优良品种为引种对象,在引种驯化及区域试验的基础上,综合分析与评价子代生态适应性、生长表现及果实品质,确定YSH和HJN为高寒地区引种栽培的适宜品种,且品种内家系间数量性状变异较小,生长稳定,具广泛推广应用价值。

In order to enrich the resources ot PLcological and Economlc iorest species in the cold area,develop variety of the creature and accelerate the construction of ecological and industrial system, Following resemble principle between the environmental conditions of seed zone and introduction area, The areas introducing fine varieties in the cold area confirm to regard the suitable the Russia as the area of origin ac- cording to its own climate, soil, vegetation distribution, landform and the general configuration of the earth＇s surface, geographical position and the other main environmental situations. The Russia＇s Seabuckthorn improved varieties was employed to analyze and evaluate the adaptability, growth performance of seeding and fruit quality of foreign ecological and economic species was farther studied based on regionalization test, introduction and domestication. It was held preliminarily that two varieties of YSH, HJN grew well and the growth of quantitative character varied slightly within families which remained stable, and possess extensive generalization and utilization value.
