Studies on induction of early flowering in orchids (Phalaenopsis hybrid) cv. fuller’s sunset

G Mishra, SK Palai and MR Nath
The experiment was conducted as a pot culture trial in the shade net house located at the Biotechnology-cum-Tissue Culture Centre, College of Agriculture, Orissa University of Agriculture and Technology, Bhubaneswar during 2016-17, with three replications and seventeen treatments treated in Completely Randomized Design. The treatments consisted of foliar application of different plant growth regulators such as GA3, BAP, Kinetin and IAA; each growth regulator in four different concentrations (100 ppm, 200 ppm, 300 ppm and 400 ppm) and a control (without any growth regulators). The results of the study revealed that foliar application of plant growth regulators at various concentrations exhibited significant variation with respect to growth and flowering parameters. Among these seventeen treatments, the induction of early flowering was observed in the plants treated with kinetin @100ppm. Among the different concentration of plant growth regulators, best result with respect to most of the flowering parameters such as number of flowers per inflorescence, diameter of flower and flowering duration were recorded in plants treated with kinetin @200ppm. Considering the satisfactorily performance of plant growth regulators (especially Kinetin and Benzyl Amino Purine) under Bhubaneswar agro-climatic condition, the flower growers may be advised to take up cultivation of Phalaenopsis hybrids on a commercial scale in and around Bhubaneswar to cater the need of local as well as outside market.
