VARIETAL DIFFERENCE IN NATURAL COLONIZATION BY ARBUSCULAR MYCORRHIZAL FUNGI AND ITS INFLUENCE ON PLANT CHARACTERS AND PHOSPHORUS NUTRITION IN SESAME
Journal Title: Romanian Journal of Biology - Plant Biology - Year 2017, Vol 62, Issue 2
Abstract
Twenty accessions of sesame (Sesamum indicum L.) plants were evaluated for arbuscular mycorrhizal (AM) colonization and its relationship with growth, yield and tissue P content. Sesame accessions exhibited variations in both frequency (%F) and intensity (%M) of colonization by AM fungi. Among the accessions, 30% had a comparatively higher %F whereas in other ones the %F was more or less on par. The %M was comparatively more in 40% of the accessions while two accessions had a very low %M. AM fungi which occurred in the rhizosphere of sesame accessions belonged to two species of Acaulospora and three species of Glomus. Glomus spp was found dominant in the rhizosphere soils of sesame. Correlation studies revealed a significant positive relationship between fungal variables as well as between fungal variables and plant characters such as growth, yield and tissue P content.
