Abstract:
Vesicular-arbuscular mycorrhizae (VAM) extracted from the soil of different agroecological zones showed an average population of 1260 spores/100 g in wheat and 1137/100 g in rice fields of Pakistan. The population of VAMspores in rhizospheric and non-rhizospheric regions of both wheat and rice varied on cultivation of the crop plants. On crop cultivation, at seedling stage VAM population decreased in the rhizospheric regions which after harvest of the crop showed an increase of upto 1860/100 g soil in wheat and 1668/100 g soil in rice fields. At crop maturity, 16 VAM-species belonging to 5 genera were isolated from the rhizospheric soil of wheat and rice. At least 16 VAM-fungi belonging to 5 genera are being reported for the first time from the soil of wheat and rice fields of Pakistan.
