INFLUENCE OF PRESERVATIVE SOLUTIONS ON VASE LIFE OF THREE FLOWER SPECIES

Abstract

Three experiments were conducted in the Horticultural Biotechnology and Stress Management Lab of Sher-e-Bangla Agricultural University, Dhaka to investigate the effect of different preservative solutions on vase life of Chrysanthemum, Aster and Button flower. The experiment was consisted of eight preservative solutions viz: T 0 : Control (tap water), T 1 : 3 % sucrose, T 2 : 3 % sucrose + 200 ppm salicylic acid + 100 ppm citric acid, T 3 : 3 % sucrose + 250 ppm salicylic acid + 100 ppm citric acid, T 4 : 3 % sucrose + 100 ppm AgNO 3 + 100 ppm citric acid, T 5 : 3 % sucrose + 200 ppm AgNO 3 + 100 ppm citric acid, T 6 : 3 % sucrose + 200 ppm salicylic acid + 100 ppm AgNO 3 + 100 ppm citric acid, T 7 : 3 % sucrose +250 ppm salicylic acid + 200 ppm AgNO 3 + 100 ppm citric acid,followed Completely Randomized Design with three replications. Experimental results revealed that all the treatment influenced on vase life of three flower species. The maximum vase life of Chrysanthemum flower was found (9.33 days) in T 7 treatment whereas the lowest number of days (4.33) was recorded in T 0 treatment. Considering effect of preservative solutions on Aster flower, the maximum vase life (8 days) was observed in T 7 treatment and the minimum (3 days) was noticed in T 0 treatment. Regarding the experiment on Button flower, similar results were also observed where the highest vase life (10.33 days) was recorded in T 7 whereas the lowest number of days (4.33) was observed in T 0 treatment. Therefore, the preservative solution under T 7 treatment can be suggested for better vase life of the three flower species.
