INFLUENCE OF GA ON SEEDLING GROWTH OF LEUCAENA LEUCOCEPHALA (LAMK.) DE WIT.” CULTIVARS
Dept. of Botany , R.G. (P.G.) College, Meerut
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 GA may be beneficial in controlling weeds as Leucaena leucocephala.
