To study the effect of antimicrobial compounds on vase life of cut tuberose flowers, an experiment based on complete randomized design with four levels of aluminum sulfate (0, 50, 100 and 150 mg l-1) was conducted. The results of data analysis indicated a significant effect of aluminum on enhancing vase life, fresh weight, solution uptake, protein and carotenoid content. Mean comparison showed that aluminum sulfate with concentration of 100 mg l-1 had the maximum vase life, solution absorption, protein and pigments content and least fresh weight loss.
