Title : Effect of New Plant Growth Regulator Prohexadione-Ca on Horticultural Crops

Abstract :

Prohexadione-Ca is a plant bioregulator primarily used to suppress excessive vegetative growth in fruit trees and other crops. It is most effective in high density plantings to reduce and control crown growth and height. In addition, effects on the occurrence of bacterial and fungal diseases and on insect pests are often observed. In addition, this may reduce fruit abortion and thereby increase fruit set. It is relatively short-lived and has very favorable toxicological and ecotoxicological properties. Finally, it leads to a reduction in ethylene formation because structural similarity to ascorbic acid, a co-substrate of aminocyclopropanecarboxylic acid oxidase, another dioxygenase involved in ethylene biosynthesis. Reduced ethylene levels together with increased availability of assimilate no longer required for shoot growth explain the increase in fruit set. It improves the process of photosynthesis by increasing the concentration of chlorophyll per unit area of the leaf and the content of carbohydrates in the tissues of the bark. It participates in secondary metabolite pathways associated with antioxidant and increases plant secondary metabolites. Thus, it can be widely used in agriculture to increase production and product quality.
