(1)泡囊丛枝（VA）菌根真菌的成功商业应用取决于了解哪些因素限制了它们的分布。本研究的目的是确定特定的土壤特性，导致不同的人口VA菌根真菌发生在两个相邻的网站，在西澳大利亚州的半干旱，地中海环境。(2)从一系列实验得出结论，当接种到它们不自然发生的土壤中时，（i）真菌感染的根和产生的孢子比它们起源的土壤中少，并且（ii）优势真菌的孢子少（地点I：无梗囊孢霉（Acaulospora laevis Gerd.）（WUM 2）和Glomus sp.（WUM 3）在土壤中萌发，芽管比原土中短。(3)从随后的两个实验研究的影响，无论是调整土壤或提取的土壤溶液作为萌发介质的pH值，它得出的结论是，土壤pH值可能是重要的限制A的分布。laevis和球囊霉Glomus sp.（WUM 3）。
(1) The successful commercial application of vesicular-arbuscular (VA) mycorrhizal fungi depends on understanding which factors restrict their distribution. The aim of this study was to identify the particular soil properties which caused distinct populations of VA mycorrhizal fungi to occur at two adjacent sites in a semi-arid, Mediterranean environment in Western Australia. (2) From a series of experiments it was concluded that, when inoculated into the soil in which they did not occur naturally (i) the fungi infected fewer roots and produced fewer spores than in their soil of origin, and (ii) fewer spores of the dominant fungi (Site I: Acaulospora laevis Gerd. & Trappe; Site II: Glomus sp. (WUM 2) and Glomus sp. (WUM 3) germinated, and they produced shorter germ tubes than in their soil of origin. (3) From two subsequent experiments studying the effect of adjusting the pH of either the soil or an extracted soil solution used as germinating media, it was concluded that soil pH is likely to be important in limiting the distribution of A. laevis and Glomus sp. (WUM 3).
