To optimize nursery practices for efficient plant production procedures and to keep up to the ever growing demand of seedlings, identification of the most suitable species of arbuscular mycorrhizal fungi (AMF), specific for a given tree species, is clearly a necessary task. Sixty days old seedlings of Neem (Azadirachta indica A. Juss) raised in root trainers were inoculated with six species of AMF and a mixed inoculum (consortia) and kept in green house. Performances of the treatments on this tree species were evaluated in terms of growth parameters like plant height shoot collar diameter, biomass and phosphorous uptake capabilities. Significant and varied increase in the growth parameters and phosphorous uptake was observed for most of the AMF species against control. Consortia culture was found to be the best suited AMF treatment for A. indica, while Glomus intraradices and Glomus mosseae were the best performing single species cultures. It is the first time in the state of Gujarat that a wide variety of AMF species, isolated from the typical semi-arid region of western India, were tested for the best growth performance with one of the most important tree species for the concerned region.
为了优化苗圃实践，以实现高效的植物生产程序，并满足不断增长的幼苗需求，明确选择最适合特定树种的丛枝菌根真菌（AMF）是一项必要的任务。在根培器中培育 60 天的印楝（Azadirachta indica A. Juss）幼苗接种了六种 AMF 物种和混合接种（共生体），并在温室中保存。根据植物高度、茎杆直径、生物量和磷吸收能力等生长参数来评估这些处理方法对该树种的影响。与对照相比，大多数 AMF 物种的生长参数和磷吸收都有显著且不同程度的增加。共生体培养被发现是最适合 A. indica 的 AMF 处理方法，而 Glomus intraradices 和 Glomus mosseae 是表现最好的单一物种培养物。这是古吉拉特邦第一次从印度西部典型的半干旱地区分离出多种 AMF 物种，并在该地区最重要的树种之一中测试其最佳生长性能。
