Abstract
A wide variety trait of Bougainvillea genus has made it a decent potential as a new ornamental plant. Different type of foliage, many inflorescence, continuous bloom, first growing and short production cycle of bougainvillea plants that make them attractive to the floriculture industry. Therefore, the longevity of flowers and leaves are crucial nowadays. Apart from the external appearance, the length of their vase life has become one of the most important criteria in evaluating their quality. Petal colour and its variations also regulate the acceptance of flowers in high competitive flower market. Several researches have been carried out throughout the world on how to improve flower size, petal colour, flower bloom cycle and flower longevity. Many horticultural techniques have been conducted for different flowering and ornamental plants but there is very few literatures are found on flower quality and longevity of bougainvillea. Therefore, few methods such as physiological stresses and phyto-hormone spraying to enhance plant growth, development, flowering process and longevity of bougainvillea have been discussed in this review article
