Effective Administration of Plant Growth Regulators in Horticultural Crops: A Review

Abstract

Natural and synthetic plant growth regulators have been used with increasing frequency to modify crop plants by changing the rate or pattern, or both, of their responses to the internal and external factors that govern development from germination. The use of plant growth regulators (PGRs) in modern horticulture is well established, particularly in horticulture in industrially advanced countries, and their application is fast picking up in developing nations as well. The research review indicated that the use of plant growth regulators, regulation of plant metabolism, control of flowering, effects on fruit set and development, control of abscission, Breaking of Seed dormancy and seed germination, enhancing and regulation of flowering, controlling flower drop, fruit thinning, fruit setting, parthenocarpy, post-harvest management and extending the shelf life of horticultural crops.
