Studies on Mycorrhizal Association in Some Medicinal Plants of Azad Jammu and Kashmir

摘要

Seventy six medicinal plant s were investigated for vesicular-arbuscular mycorrhizal (VAM) association in a survey of the Azad Jammu and Kashmir. Vesicular-arbuscular mycorrhiza was found to be of universal occurrence in all plants located at different habitats. Great variations were found in the VAM infection percentage and the extent of hyphal infection. Plants at vegetative stage exhibited more VAM infection percentage compared to those at flowering and fruiting stages. Herbaceous plants showed more infections in comparison with the shrubby and woody plants. The extent of root colonization by VA endohphytes varied with the soil type and plant species. Endophytes other than VA were also recorded.
