Abstract
A Postharvest experiment was conducted to maximize the vase life of gladiolus using different preservative solution in Department of Horticulture, Faculty of Agriculture, Annamalai University. In this experiment the treatment consisted of two preservative chemicals viz., 8-hydroxy quinoline sulphate @ 150, 300, 450 ppm and silver nitrate @ 25, 50, 75 ppm along with sucrose @ 2 and 4 per cent along with control (distilled water). The results of this experiment revealed that the maximum water uptake, transpirational loss of water, water balance, fresh weight change, percentage of opened florets, floret diameter, longevity of floret, vase life was recorded in T5 (8-HQS @ 300 ppm + sucrose 4%), when compared to control. Some parameters like optical density of vase solution, days taken for the basal floret to open in vase and the percentage of wilted florets were observed least in T5 (8-HQS @ 300 ppm + sucrose 4%). T5 (8-HQS @ 300 ppm + Sucrose 4%) solution was found best to extend the vase life of gladiolus.
