Dieback and mortality of plantation Japanese larch (Larix kaempferi) associated with infection by Phytophthora ramorum
invasive conifer sporangia
2014/11/25
The invasive pathogen Phytophthora ramorum is the cause of 'sudden oak death', a dieback and mortality of more than one million live-oak and tanoak trees along 1500 km of near-coastal native forest in...
Regeneration Process of Broadleaved Trees in Planted Larix kaempferi Forests
broadleaved tree buried viable seed planted larch forest regeneration habit thinning

日本落叶松群体的叶绿体SSR分析Analysis of Genetic Structure in Population of Larix Kaempferi by Chloroplast SSR Markers
叶绿体微卫星 日本落叶松 单倍型 群体遗传结构
2008/1/8
摘要
利用叶绿体微卫星（cpSSR）分子标记对日本国内的7个日本落叶松（Larix kaempferi）群体遗传结构进行了研究。11对cpSSR引物中筛选出的3对多态性引物，共产生10个长度不同片段，在197个样品中组合出现10个不同的单倍型（haplotype）。各群体的单倍型差异较大。cpSSR基因座揭示了日本落叶松的遗传变异：平均等位基因数A=3.33，平均有效等位基因数NE=1.20，基...
