Abstract
Growth of R. solani was markedly influenced by GA3, kinetin but not by IAA. The mycelium used for inoculation of groundnut hypocotyls was obtained from cultures grown on solid media supplemented with various concentrations of GA3, kinetin and IAA. The virulence was evaluated by measuring the lesion size 48 hours after inoculation. Gibberellic acid followed by kinetin caused enhanced lesion size at 0.5 μg/ml in the medium. A correlation was observed between the infection cushions produced and the virulence of the pathogen. [ABSTRACT FROM AUTHOR]
