Vesicular-arbuscular mycorrhizal associations of sesamum

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

Extensive mycorrhizal infection of sesamum under field conditions was observed. The plants were found to be mycorrhizal even in the early stages. There was a progressive increase in mycorrhizal infection up to 6 weeks, then declined slightly. A gradual increase in vesicle count per 1 cm segment as the plants aged was noticed. Species ofGlomus, Gigaspora andSclerocystis were found in the rhizosphere soil. Among the spore types recorded, chlamydospores ofGlomus, especiallyGlomus mosseae were predominant.
