Abstract
Field experiment was carried out to investigate effect of foliar application of Plant Growth Regulators (PGRs) like 6-benzylaminopurine (6-BA), gibberellic acid (GA), chlormequat(CCC), salicylic acid (SA), cysteine and methionine with 5 and 20 ppm concentration on vegetative growth of Simarouba glauca DC. Foliar application of both concentrations of all the PGRs promoted root length, shoot length, height of plant, number of leaves per plant, leaf area, fresh and dry weight of leaf, stem, root and fresh and dry weight per plant. The significant increase in plant height, leaf area and dry weight were obtained in plants treated with GA, SA and methionine while 5ppm GA gave highest number of leaves per plant. This will improve the availability of plant biomass for extraction of various bio active molecules in pharmaceutical industries.
