Effect of different floral preservatives for improving the vase life of cut spikes of orchids (cv. Sonia-17)

The present research work entitled "Effect of different floral preservatives for improving the vase life of cut spikes of orchids (cv. Sonia-17)" was conducted to evaluate the most effective floral preservative for Dendrobium cv. Sonia-17. The entire experiment was carried out in a completely randomized design with 10 treatments and 3 replications. Among the treatments, T5 8-HQS (200 ppm) + Sucrose 2.5% + Glucose 5% was found to be the best, performing a significant enhancement in the vase life of cut spikes compared to all other treatment combinations. This treatment also exhibited notable improvement across almost all observed parameters, signifying its better-quality role in maintaining the post-harvest superiority of Dendrobium flowers.
