ABSTRACT
An experiment was carried out during winter season of 2015 in Department of Floriculture and Landscape Architecture, University of Horticultural Sciences, Bagalkot, during the year 2015-16. The experiment was conducted in randomized block design with 5 treatments or growth regulators of different concentrations along with one control as water spray. Gibberellic acid (G1- GA3 at 200 ppm), NAA (G2- at 60 ppm), Cycocel (G3- CCC at 1000 ppm) and TIBA at 1000 ppm (G4) replicated thrice to evaluate the effect of these plant growth regulators on growth, flowering and yield characters in African marigold. The observed vegetative traits like plant height, numbers of primary and secondary branches per plant and plant spread and different flowering as well as yield attributing traits like early flower bud initiation, opening of first flower and maximum duration of flowering and and flower yield per plant were found to be maximum from the treatment Gibberellic Acid @ 200 ppm as compared to other treatments.
Key words: GA3-Gibberellic acid, NAA- Alpha - Naphthalene acetic acid, CCC-Cycocel or 2-chloro ethyl trimethyl ammonium chloride and TIBA-2, 3, 5 triiodobenzoic acid.
