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.
