藤本植物是森林群落的重要组成部分，对森林的整体结构和功能具有重要影响。藤本植物具有广泛的无性系繁殖的特点，这对它们的建立和生长至关重要。先前的研究表明，藤本植物的克隆繁殖策略在不同物种之间存在很大差异；然而，很少有研究对多株共生藤本植物的克隆策略进行定量评估。本研究的主要目的是通过评估森林地面上的小茎和爬树的成熟茎，来评估克隆繁殖的相对贡献，并了解共生藤本植物的克隆增殖过程。采用遗传分析的方法，对日本中部一古老温带森林6 ha样地和带样带中4种常见藤本植物（茎缠绕植物紫藤、根攀缘植物绣球花、卫茅和双柳）的无性系繁殖策略进行了评价。无性系繁殖对攀根植物的贡献小于对攀根植物的贡献。多花植物。AllW。在林下具有小分枝的开花植物具有爬树的遗传相同的分枝，而在根攀缘植物中却很少发现这样的分枝。这表明w。花期分株通过无性系繁殖产生小分株，而攀根分株的幼苗则水平生长以爬树。结果表明，藤本植物的无性系繁殖过程存在较大差异，无性系生长在藤本植物生活史策略中起着重要作用。
Lianas are important components of forest communities with a considerable impact on overall forest structure and function. Lianas are characterized by extensive clonal reproduction on the forest floor, which is important for their establishment and growth. Previous studies have suggested that clonal reproduction strategies vary substantially among liana species; however, few studies have quantitatively evaluated the clonality strategy in multiple co‐occurring liana species. The primary objective of the present study was to evaluate the relative contribution of clonal reproduction and to understand the clonal proliferation processes in co‐occurring liana species by assessing both small stems on the forest floor and mature stems that climbed trees. The clonal reproduction strategy in four common liana species (stem twiner:Wisteria floribunda; root climbers:Schizophragma hydrangeoides,Euonymus fortuneiandRhus ambigua) in a 6‐ha plot and a belt transect within an old‐growth temperate forest in central Japan was evaluated using genetic analysis. The contribution of clonal reproduction was smaller in root climbers than inW. floribunda. AllW. floribundagenets with small ramets in the understory had genetically identical ramets that climbed trees, whereas few such ramets were found in root climbers. This indicates thatW. floribundamature ramets laterally produce small ramets via clonal proliferation, whereas seedlings of root climbers grow horizontally to climb trees. The results indicate that the clonal reproduction processes differ greatly among lianas and the clonal growth in lianas plays a contrasting role in their life‐history strategy.
