Abstract:
Nodule and root initiation in Cajanus cajan plants inoculated with vesicular—
arbuscular mycorrhizal fungus and Rhizobium was studied Mycorrhizal
association enhanced the success of nodule formation with no significant difference
in number of root initiated in a specific area. Further, there was increased cytokinin activity in stem exudate and root of mycorrhizal plants. Based on the observations
a hypothesisis proposed for the mechanism of enhanced nodulation in mycorrhizal
legumes.
