摘　　要：为了解掌握红松分杈现象研究现状,以便充分利用现有成果并为下一步深入研究奠定基础,本文综述红松分杈原因及预防措施、分杈与密度关系、分杈及树体调控与结实关系、红松分杈在其培育中应用等方面的研究成果。我国早期研究是把分杈作为一种影响木材培育的不良现象而进行的,研究集中在分杈原因与预防措施方面,近年来才关注分杈对生长及结实的影响、分杈与林分密度的关系,个别研究深入到分杈的生理机制,并有人工截顶促杈研究;韩国对种子园母树截顶促杈的研究比较系统。这些研究结果有一些可以直接应用于红松种子园、坚果专用林和果材兼用林定向培育技术建立上,未来应加强从发育生物学、营养生理学、生殖生物学和系统人工调控技术等角度进行深入系统的长期定位研究。For the purpose of understanding the current situation and future issues in research on branching phenomenon of Pinus Koraiensis,this paper reviewed the research achievements in Korean pine on the cause and prevention measurements of branching,the relationship between branching and stand density,the relationship between cone-setting and branching / crown-control,and the application of branching in its silviculture. The early research in China was focused on the causes and preventing methods for branching of Korean pine because the branching phenomenon was believed to be harmful to the timber production. Recently,the influence of branching on the growth and cone-setting,the relationship between branching and stand density,the physiological asspects of branching,and top-pruning were taken into consideration in the studies related. Top-pruning and crown-control for seed orchard Korean pine trees were well conducted in South Korea. These results could be used in establishing silvicultural systems of Korean pine seed orchard,nut production plantation and combined production plantation of timber and nut. Future studies should pay much more attention to systematic and long term research from point of developmental biology,nutritional physiology,reproduction biology,and artificial control technology establishment.
