Abstract

Pulsing cut Gypsophila paniculata L. cv • Perfecta' stem with only 5% of
buds 0eren in STS 1:4 mM for 30 min or GA;, at 25 ppm for over night before storage
at 5 C for several durations as simulate transport reduced days required to
marketable stage and wilting flowers during shelf life period. Also these treatments
promoted buds opening, prolonged display life, Improved water uptake and water
balance and maintaining carbohydrate level at the end of vase life as compared to Ki
at 5 ppm and control (D.W) treatments, respectively.
The increased storage period was negatively effective on most parameters studied.
On the other hand, display life after the end of storage period at 5 0 C for 15 days was
recorded (12.45 and 12.72 days) as compared to (13.63 and 13.65 days) for the
control without any treatment in the two seasons, respectively. These led to say that,
this period (15 days) is suitable for maintaining price of gypsophila cut flowers.
Maintaining quality of cut flowers at ambient environmental of lab at 18°C ± 2 and 50-
55 RH after the end of storage periods was by holding flowers in holding solution
containing sucrose + 8-HQS + Tween -20. This treatment showed highly significant in
enhancing parameters of gypsophila cut flowers, during observation time in lab.
