摘要: <正>利用包括 5个北美鹅掌楸种源和 1 5个马褂木种源的遗传试验林 8年生测定材料 ,从生态适应性、侧枝形成分叉干特性、树高和胸径生长、干形和木材密度等系统评价北美鹅掌楸南部种源在我国东南地区的引种造林效果。研究发现 ,北美鹅掌楸虽然侧枝形成分叉干率低 ,但生长较缓、干形较差、植株死亡率很高 ,综合表现远不如乡土树种马褂木的一些优良种源。为达到引种成功 ,建议选择中等以上立地作为引种造林地 ,并加强根系发达的优质苗木培育和幼年抚育。笔者认为引种北美鹅掌楸的目的在于丰富种间杂交的育种资源 ,而不在于丰富本地区的造林树种。在 5个北美鹅掌楸参试种源中 ,来自较内陆的 Missouri种源的表现最好 ,可将之作为种间杂交育种的亲本种群

Abstract: A provenance test at age eight including five provenances of L. tulipifera and fifteen provenances of L. chinense was made to evaluate systematically plant performance in Southeast China from ecological adaptability, stem forking, growth rate, stem form and wood density. The results indicated that, in spite of less stem forking proportion, tulip tree is inferior to native L. chinense .The former has low growth rate, poor stem form and high mortality. Good site would be selected as plantation site to warrant successful introduction of tulip tree. It is very important to cultivate sound seedlings with rich root and tend young stand in time. The author suggests that introduction of tulip tree mainly aim to richen breeding resources for interspecific crossing, not plantation species. Among five tulip tree provenances tested, the interior Missouri performed best, which clould be selected as parent population for interspecific crossing.
