The Effects of Different Vase Solutions on the Postharvest Life of Rose Flower- Review

Abstract

One of the utmost difficulties in postharvest of rose flower is the blockage of vascular system, due to air or bacterial growth, which reduces water uptake and blocks xylem vessels leading to water stress. That was expressed in the form of early wilting of leaves or flowers, and might appear when water uptake and transpiration are out of balance during a lasting period of time. This finally leads to an unrecoverable situation and the premature end of flower vase life. Antimicrobial compounds like metal salts prevent and slowdown bacterial growth, ensure proper water uptake and delay senescence. Different Preservatives solution are used to increases the longevity of many cut flowers including, sucrose as source of nutrition for tissues approaching carbohydrate starvation, Silver in the form of Silver Thiosulphate (STS) to inhibit the action of ripening/senescence hormone ethylene, aluminum sulfate to lower the pH of vase solution and as an antimicrobial agent in the solution and salicylic acid to prevent ACC-oxidase activity that is the direct precursor of ethylene and decrease ROS with increase enzyme antioxidant activity. Currently, synthetic germicides containing AgNO 3 are no longer used in commercial vase solutions because the silver can pollute the environment and cause damage to human health. Thus, it is better to use ecofriendly extracts of several plant species contain antimicrobial compound that has the potential to be used as a natural germicide in floral preservative solutions of vase cut flowers.
