In pot culture studies, metabolic activities were correlated with the effect of exogenous application of cytokinin at certain level (0.0, 1.0, 4.0, and 10.0 ppm) of cytokinin in mint (Mentha piperita L.) under variable seasons. In summer season, the higher level of cytokinin i.e. 4.0ppm resulted in vigorous vegetative growth. All the parameters studied were also affected in winter season also, but values were too low than those in summer season. It showed a positive correlation with the growth attributes and menthol oil contents in trichome glands of mint under the influence of variable sea sons. Thus, both cytokinin and long day treatment provides a great significance in control ling the growth and yielding capacity of mint plant.
