简介：忍冬confusa，为治疗感冒的繁体中文药植物，流感，等等，急性发烧经常在酸的土壤人工地被种并且受不了磷(P)缺乏。一个五年的地实验被执行学习殖民率，生长，营养，和与arbuscularmycorrhizal(AM)接种的忍冬confusa幼苗满意的chlorogenic酸真菌，血管球etunicatum和血管球intraradices。在移植进一个领域前，接种AM并且uninoculated控制植物在托儿所床上是有教养的。在与AM真菌接种的植物，殖民率与时间线性地减少了，更大的减少在与G接种的植物被观察。intraradices比与G。etunicatum，当AM殖民在uninoculated从0%～12.1%增加了时，控制在移植以后种5年。植物高度，王冠直径，新分支的数字，和花产量作为与uninoculated控制相比由AM接种显著地增加了。在增加的叶子和花的磷集中，和营养素的植物举起，例如，氮(N)，P，和钾(K)，被AM也显著地提高接种。忍冬confusa幼苗有更好的回答到G的接种。intraradices比G。在生长的etunicatum和在花的chlorogenic酸内容。相反，两个都在叶子和花种P举起和P集中在二真菌的接种之间是类似的。到在生长，滋养的举起，flowering，和在花的chlorogenic酸内容的AM接种的忍冬confusa的积极回答建议当在酸、P缺乏的土壤上成长时，在托儿所床上的那AM接种能在忍冬confusa的花支持植物生长和增加chlorogenic酸内容。
