东北黑土区俄罗斯第三代沙棘良种适应性初步评价

The Evaluation for Introduced Seabuckthorn Adaptation of the Third Russia′s Generation in Northeast Black Soil Area

俄罗斯的第三代沙棘良种,代表了国际上沙棘良种资源的先进水平。以2013年引进的22份俄罗斯沙棘优质资源为试材,在东北黑土区通过对其成活率、保存率、生长及物候差异分析研究,构建隶属函数,以综合指数为指标,对各引种资源给予适应性初步评价,以期为后续研究提供理论依据。试验结果表明,各引种资源成活率、保存率、生长及物候情况存在明显差异,其中201307、201320和201304等材料,在东北黑土区初步表现较为优异,应成为下一步区域性试验的重点品种。

Russia＇s third generation of seabuckthorn good varieties represent the international advanced level of seabuckthorn resources. In 2013, taking 22 introduced varieties of Russian seabuckthorn resources as the test materials in the Northeast black soil area,based on the survival rate,conserving rate, growth and phenology variance analysis research, the membership function has been constructed by the composite index as the indictors to evaluate the adaptation of introduced resources and to provide theoretical basis for further research. Test results shown that there are obvious differences among the introduced resources on the survival rate,conserving rate,growth and phenology, the performance of 201307,201320 and 201304 are more outstanding in the Northeast black soil area which should be the important varieties for further study.
