Studies carried out on the effects of growth regulators on the biochemical composition and yield in Jasminum multiflorum had shown that flower yield can be increased by spraying cycocel at 500 ppm. It recorded high C/N ratio at the flowering phase and was associated with higher quantum of yield among all the treatments. NAA treatments increased the C/N ratio during peak flowering, when better yields were obtained from NAA treated plants. Cycocel increased the nutrient and carbohydrate content by greatly retarding the growth of the plants. The judicious application of these two growth regulators, therefore, will be useful in extending the flowering season and duration of flowering. The extension of season of flowering and staggered supply of flowers to the market would ensure avoidance of glut and better returns to the grower.
