Abstract
An experiment was conducted to study the effect of Piper betle leaf extract (PbLE) for prolonging vase life and keeping quality of cut spike of tuberose. Treatments consisted of four vase solutions, viz., distilled water (control), 3 % sucrose (T1), 3 % sucrose + 100 ppm 5-SSA (T2), 3 % sucrose + 50 ppm PbLE (T3). The PbLE in T3 vase solution might have played a significant role to scavenging the reactive oxygen species by inducing antioxidant enzyme system at the time of senescence, leading to decrease in lipid peroxidation and increase the membrane stability. Results suggest that application of T3 vase solution helps to maintain spike fresh and dry weight, improves antioxidative defence, stabilizes membrane integrity leading to delay senescence and thus makes it potential to be used as a commercial vase solution for cut spike of tuberose.
