The effects of certain Plant Growth Regulators, viz., IAA, IBA and GA3,have been studied on the life cycle of Achlya diffusa Harvey ex Johnson. 0.005% concentration of IAA showed the best growth in culture medium whereas inoculums, dipped for one minute in 0.005% concentration and inoculated on medium showed the best growth. 0.0005% concentration of IBA showed the best growth in culture medium whereas inoculums, dipped for one minute in 0.005% concentration and inoculated on medium showed the best growth. 0.05% concentration of GA3 showed the best growth in culture medium whereas inoculums, dipped for one minute in 0.5% concentration and inoculated on medium showed the best growth. The dry-weight assessment (in mg) of the growth indicated very clear-cut results with a different sequence. The maximum dry-weight of the colony was in 0.05% of GA3 followed by 0.0005% of IBA and 0.005% of IAA over the control. All the PGRs have shown definite morphological changes at different stages of the life cycle of Achlya diffusa.
