The ARBUSCULAR MYCORRHIZAL STATUS OF SOME ETHNOMEDICINAL AND MEDICINAL PLANTS OF PASCHIM MEDINIPUR
Abstract
Paschim Medinipur district is rich in ethno medicinal flora. Arbuscular mycorrhizae (AM) are obligate symbiotic fungi which activates nutrient and water uptake in plants. A survey was conducted to evaluate the Arbuscular mycorrhizal status of ethno-medicinal plant species from lateritic belt of Jhargram, Garhbeta and Midnapore subdivisions. Root and rhizospheric soil samples were investigated for arbuscular mycorrhizal colonization and AM spore. Species belonging to the families Poaceae, Lamiaceae, Meliaceaeand Papilionaceae showed maximum colonization with high intensity class and presence of arbuscular vesicles. Species with wide distribution showed comparatively high colonization than locally confined species. So status may be related to their availability, though some tendency of host preference was noticed.
