Effect of foliar application of plant growth regulators on vegetative growth of Simarouba Glauca DC.

A field experiment was carried out to investigate effect of foliar application of Plant Growth Regulators (PGRs) e.g. 6-benzylaminopurine (6-BA), gibberellic acid (GA), chlormequat (CCC), salicylic acid (SA), cysteine and methionine at 5 and 20 ppm concentrations on vegetative growth of Simarouba glauca DC. Foliar application at both concentrations of all PGRs promoted root length, shoot length, height of the plant, number of leaves per plant, leaf area, fresh and dry weight of leaf, stem, root and fresh and dry weight per plant. Significant increases in plant height, leaf area and dry weight were observed in the plants treated with GA, SA and methionine, while treatment with 5 ppm GA gave highest number of leaves per plant.
