| 摘 要： | 以猪血木幼苗为研究对象,在非灭菌条件下进行幼苗接种丛枝菌根的盆栽试验.通过测定幼苗株高、叶片光合色素含量和叶片数生长动态.结合动态生命表和株高增长动态分析方法.探讨了非灭菌条件下丛枝菌根对濒危植物猪血木幼苗生长的影响.结果表明,与对照组相比,接种丛枝菌根提高了叶片光合色素的含量.显著提高了幼苗的存活率,促进幼苗的株高和叶片生长;动态生命表分析表明.接种丛枝菌根的幼苗在生长初期的48周中无明显的危险死亡期:对照组幼苗存活率曲线为Deevey-Ⅲ型,幼苗在初期表现出较高的死亡率.故接种丛枝菌根能促进猪血木幼苗的生长,增强幼苗对环境的适应性,提高幼苗的存活率.研究结果为该濒危物种的有效保护和种群恢复提供了理论依据.

| Abstract: | Euryodendron excelsum H.T.Chang is an endangered species from the family Theaceae endemic to China.It has been reduced to one remnant population with less than 200 individuals in Bajia region of Yangchun County, Guangdong Province.The species is listed as a Grade Two endangered plant for state protection in the Red Data Book of plants in China.A pot experiment was conducted toinvestigate the effect of indigenous Arbuscular Mycorrhizal(AM) inoculation on the seedling growth dynamics of E.excelsum under non-s... |
