Evaluations of the Vase-Life of Tuberose (Polyanthes tuberosa L.) Cut-Flower Spikes Cv. âBizetâ in Micro-Cold Storage (mCS of EcofrostTechnologies Pvt. Ltd.) and Room Temperature (Rt)

Abstract

The experiment was conducted at Ecofrost Technologies Pvt. Ltd., Survey no 134/1, 134/2, 130/3, Jeevan Nagar, Tathawade, Pune, Maharashtra, India. In this study, the effects of sucrose and citric acid in holding solution treatments on the post-harvest vase-life of cut spikes of tuberose cv. Bizet were carried out. After 24 hours holding cut ends of tuberose spike in 5% sucrose solution were studied at room conditions, and then sucrose 5% solution treated two spikes were selected for each replication. The ends of 2 cut spikes were treated with the desired concentration of related holding solution treatments each replication-wise before storage. The treatments T2, T3 and T4 treated spikes along with holding storage treatments were kept for 10 days at 40°C and 92.5% RH under mCS of Ecofrost Technologies Pvt. Ltd, Pune. The T1 treated spikes were kept at room condition. The holding solution treatment 2 % sucrose+citric acid 0.2% (T4) resulted in the maximum weight of single cut spike (gm), number of opened flowers (16) per spike, vase life of spike (14.15 days) and the minimum number of unopened flowers (4.32) per spike, in trial under laboratory conditions tuberose cv. Bizet and then followed by sucrose 2% (T1), tap water (T2) and control treatment (tap water) (T3).
