Abstract

Abstract:The status ofthe arbuscular mycorrhizal fungi of some species from North areas of Solapur,Maharashtra was analyzed. All the species selected from study areas showspresence of percentage of root colonization with all types of infection ashyphal, vesicular and arbuscular type. Percentage of root colonization showsvariation with the infection to the selected plant species. The percentage ofroot colonization ranged from 20% to 80%. The maximum root colonization found in Heteropogon contortus L. (80%) followed by Euphorbia heterophylla L.(70%), all other plant species showspresence of root infection with varied ranges. Arbuscular mycorrhizal sporepopulation present between 100 to 600 in 50 gm of rhizospheric soil collectedfrom site. The highest sporulation was found in Commelina erecta L (600/50gm soil)belonging to the family Commelinaceae and lowest in Cassia auriculata L(100/50gm soil) belonging to the familycaesalpinaceae .  The pH of the soil wasalso recorded which ranges between 6.4 to 7.0 which have impact on sporulation.
