The Role of Gibberellins and Cytokinins on Florists’ Greens Post-Harvest Shelf Life
Journal Title: International Journal of Research and Advances in Agricultural Sciences - Year 2022, Vol 1, Issue 1
Abstract
Since the vase life of florists' greens must correspond to that of the flowers, this article summarizes the findings of studies undertaken over the years to increase the post-harvest lifetime of species raised for florists' greens by means of gibberellins (GAs) and cytokinins (CKs). Foliage and the non-leafy stems of herbaceous plants, trees, shrubs, and phylloclades are all considered florist greens. Florist greens' freshenss and durability after harvest are largely determined by their genetic makeup. Florists' greens are also profoundly influenced by their growing circumstances, the conditions of their transportation, and the conditions in which they are supplied to markets. In addition, growth regulators, which are essential in the aging process, are not provided for florists' greens. Though CKs and GAs are thought to slow the aging process, they become less abundant as plants age, giving way to regulators that hasten the process. The use of growth regulators in the post-harvest treatment of florists' greens is the subject of international study. Research shows that the success of these treatments varies widely depending on factors including species, cultivar, concentration, and application technique; hence, there is no universally applicable formula. Greens used in floral arrangements are conditioned with CK and GA growth regulators. Few studies have shown promise for employing topolines (Ts) and ionic liquids to increase the shelf life of florists' greens after they have been harvested. Florists' greens of most species do not benefit from conditioning in the typical cut flower medium containing 2% sucrose and hydroxyquinoline esters-sulphate or citrate (8HQS and 8HQC) at a concentration of 200 mgdm3.
