摘要：春季柚木1～3年生幼树在主梢萌动抽生之前,在基部以上3m范围内侧芽普遍抽生,为掌握柚木幼树侧芽萌发特性与了解相关影响因子,对柚木无性系测定林、施肥试验林、实生起源同龄混交林幼树开展了侧芽萌发情况调查,对不同重复不同处理不同地块柚木侧芽萌发特性和相关因子进行统计分析,结果显示:柚木抽生侧芽特性受遗传、施肥措施、和立地因素的影响,其结论对柚木立地质量评价、无性系品种选择和柚木的集约经营有较大的启示作用。
In spring, lateral buds of Tectona grandis L. f. saplings in 1-3 years germinate widely at base more than 3 m high before main treetop germinating. Survey on bud germination was made in clone test stands, fertilization test stands and same-aged seedling mixed saplings, and statistic analysis was made on lateral bud germination char-acteristics and relative impact factors of Tectona grandis L.f. in different sites, in different repeated clone tests and in different treatments. The results show that lateral bud germination characteristics were affected by heredity, fertilization and site. This conclusion may play an enlightening role on site quality evaluation, clone species selec tion and intensive management.
