Effect of different concentrations (50, 100, 200, 500 ppm) of GA was studied on seedling growth and development in eleven cultivars (Peru, Pirasicana, Campena grandi, Gum variety, K-28, MU, FG-3, FG-6, FG-9, K-8 and FG-13) of Leucaena leucocephala to find out the inhibitory concentration for different seedling parts. Appreciable reduction in seedling growth was observed in Peru, CG, K-8, FG-9 & FG-13 cultivars specially in 200 and 500 ppm. Higher than physiological concentrations of Plant growth Regulators (PGRs) specially GAmay be beneficial in controlling weeds as Leucaena leucocephala.
