 ABSTRACT

The present investigation was carried out at Medicinal Research and Development Centre, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, during Novemberr 2016 to April 2017 to evaluate the effect of plant bio-regulators viz., NAA, IAA and gibberelic acid, each at three concentrations (25, 50 and 100 mg l-1) on chamomile (Matricaria chamomilla L.). The experiment was laid out in Randomized Block Design (RBD) with three replications and ten treatments. During the study, observations were taken for various vegetative and floral parameters like plant height (cm), number of branches per plant, plant spread (cm), total number of roots per plant, total biomass of plants, stem diameter (mm), days taken to first bud initiation, flower diameter (cm), number of flowers per plant and fresh and dry weight of flowers per plant (g). Among the different treatments, GA3 at 100 mg l-1 was found to be the best treatment for most of the parameters viz., plant height (44.54 cm), number of branches per plant (38.20), plant spread (54.00 cm), days taken to first bud initiation (15.53), flower diameter (2.57 cm), number of flowers per plant (368.93), fresh weight of flowers per plant (35.56 g) and dry weight of flowers per plant (6.96 g), whereas, NAA at 100 mgl-1 proved to be the best for stem diameter (6.76 mm). GA3 @ 100 mgl-1was found to be the most effective for most of the vegetative and floral characteristics of chamomile cv. CIM Sammohak.

Key words: Chamomile, IAA, GA3, NAA, Vegetative growth, Floral traits
