Seasonal Changes Of Arbuscular Mycorrhizal (AM) Fungi
In Euphorbiaceae Plants From Ramling, Balaghat Plateau
Of Maharashtra, India.
SCIENCE PARK, (November 2013)Abstract
Seven plants belonging tofamily Euphorbiaceaewere studied for their AM associationduring the three seasons. The result showed that all the plants vizEuphorbia hirta, Euphorbia geniculata,Euphorbia heterophyll.,Euphorbia microphylla, Euphorbia prostrate, Euphorbia pulcherrima and Euphorbia
tirucali had AM fungal association in the roots and spore population in the rhizosphere soil.During rainy season only two genera Acaulospora(1 species) and Glomus(2 species) were recorded. During winter season four genera were observed namely Acaulospora(3 species), Gigaspora(2 species), Glomus(5
species) and Scutellospora (1 species).During summer season three genera were identified Gigaspora (1 species),Glomus(2 species) and Scutellospora(1 species). The chlamydospore count was highest during winter season and lowest during rainy season. Euphorbia tirucali was found highest root colonization in winter as compared to other native hosts screened during the three seasons, whereas Euphorbia microphylla was found negative for
arbuscular mycorrhizal fungal colonization.
