Studies on ecological genetics of beech ecosystem in north-eastern Japan

本报告载有参与这一项目的研究人员所描述的下列项目。研究目的：对天然山毛榉种群遗传同工酶分析、山毛榉林地条件的气候和土壤同工酶研究、种子自然更新和萌发更新等进行了研究。然后对山毛榉森林进行了景观分析，并从动植物保护和生态遗传学的角度对山毛榉森林的遗传资源保护和饲养管理进行了综合探讨。日本山毛榉森林概况3。前言：日本山毛榉生态学研究成果4。山毛榉天然林同工酶遗传分析1)同工酶研究地点的气候、土壤和蓄积量调查2)天然山毛榉林(种群)的遗传分析，天然山毛榉林分亚种群的遗传分析5。山毛榉天然林的维持机制1)种子自然更新2)萌芽和粪便自然更新6。天然山毛榉林景观分析7。山毛榉森林保护与饲养管理一体化探讨1)山毛榉遗传资源保护2)山毛榉森林景观保护

This report contained following items described by respective researchers participated in this project.1. Research objectives : Following items such as population genetics of natural beech forests using isozyme analysis, climatic and edaphic evaluation of isozyme study site condition of beech forests, natural regeneration by seed and sprout were studied. Then, landscape analysis of beech forests was made, and from the view points of fauna and flora protection and of ecological genetics, conservation of genetic resources and raising management of the beech forests were integratively discussed.2.
