The vase life of cut flowers and foliage is often shortened by vascular occlusions that constrict vase solution supply. Reduction in stem conductivity is typically caused by blockage of cut stem ends and xylem conduits by microbes, physiological plugging, and disruption of water columns in xylem vessels by cavitation and air emboli. Cut flower and foliage longevity can be greatly affected by the chemical composition of the vase solution. In present study Citric acid-100ppm, Aluminium Sulphate-100ppm and 1% Sucrose were used in different combination to enhance the longevity of Tithonia rotundifolia Blake cut flower.
