An experiment was conducted to study the physiological and flowering behavior of Bougainvillea glabra cultivars. Plant morpho-physiological and flowering characteristics of Bougainvillea were observed during one year of study. It was observed that leaf and shoot growth rate were higher in earlier stage compared to later stage. Leaf, shoot and bract growth were also higher until 11 days from the initial days of observation. Flowering was greatly reduced or completely inhibited during the vegetative growth of the plant. It took 12 days to initiate the flowering bud from the vegetative stage. From this experiment, it was also recorded that the complete life cycle of Bougainvillea bract including flower around 28 days. Leaf pigments content; chlorophyll a (2.2 mg/gFW), chlorophyll b (1.8 mg/gFW) and Carotenoid (1.03 mg/g FW) were recorded at flowering stage. At the bud developmental stage, chlorophyll fluorescence, stomatal conductance and total sugar content of Bougainvillea leaves were 0.78, 25 m2S/mol and 0.28 mg/G. Leaf nutrients N, P and K content at the vegetative stages were recorded around 2.18, 0.29 and 0.95 mg/L. This study will help further research about the vegetative growth and flowering behavior of Bougainvillea plant.
