10.22376/ijpbs.2019.10.1.p1-12 Volume 5 Issue 1 2014 (January - March) In order to survey biodiversity and root colonization of arbuscular mycorrhizal fungi (AMF) on date palm ( lessThan i greaterThan Phoenix lessThan /i greaterThan lessThan i greaterThan dactylifera lessThan /i greaterThan L.) tree, the present study was undertaken in semi-arid areas of Jaipur district at fifteen sites. The genera identified were lessThan i greaterThan Gigaspora, Glomus, Scutellospora, Entrophosphora lessThan /i greaterThan and lessThan i greaterThan Sclerocystis lessThan /i greaterThan . The root colonization by AM fungi varied significantly, ranging from 78% to 93% in date palms rhizosphere. lessThan i greaterThan Gigaspora lessThan /i greaterThan species were found in abundance and their occurrence frequency ranged from 60-70%, lessThan i greaterThan Glomus lessThan /i greaterThan species from 40-50%, lessThan i greaterThan Sclerocystis lessThan /i greaterThan upto 30%, lessThan i greaterThan Scutellospora lessThan /i greaterThan from 10-20% and lessThan i greaterThan Entrophosphora lessThan /i greaterThan upto 10%. lessThan i greaterThan lessThan /i greaterThan Overall evaluation revealed that the root colonization and the spore population varied to different extend. The AM colonization and number of spores in date palm roots were found to be negatively correlated with soil phosphorus content and electric conductivity of soil samples and positive correlation between number of spores and root colonization AMEETA SHARMA AND NEHA GHEEK BATRA Diversity, AM fungi, date palms, physico- chemical parameters 819-826
