Post-harvest technology is essential to maintain the quality and freshness of produce from harvest to use by end consumers. The main aim of post-harvest preservation is to elongate the vase life of cut flowers and improve their quality in the market (Wani et al., 2023).

There are several techniques to extend the shelf life of flowers and fl ower preservation, including the use of ethylene action inhibitors, growth regulators, floral preserving treatments, temperature regulation and flower dehydration.

Stage of harvesting
Initially, a major concern for improved longevity of flowers is the proper stage of harvesting the plant according to the distance to deliver. The use of sucrose in a pulsing solution or as a component of a vase solution delays the senescence of cut flowers either by increasing water balance and energy or with a decrease in ethylene production.

Water quality
Techniques such as reverse osmosis and UV sterilization help to improve the quality of water used in flower care as water quality is highly essential for post-harvest vase life.

Temperature
Storage in lower temperatures is highly applicable to reduce carbon dioxide concentration and ethylene production in flowers but, chilling sensitive flowers as bird-of-paradise, heliconia, and orchids, cannot be stored below 10- 13°C because of the severe tissue discoloration.
