Effect of plant growth regulators on cucurbits: A review

Abstract

Plant growth regulators are used to alter a crop by changing the rate or pattern, or both, of its response to the innate and exposed factors that govern development from seed germination to the new seed development through the various physiological as well as postharvest impact. Cucurbits are the major group of vegetables grown all over world and they are responsive crops towards the growth regulator. PGR’s play vital or key role in increase growth, yield and quality. The spray of GA3 50-100 ppm increases growth, number of male flowers and weight of fruits. Ethrel 400-500 ppm increased number of female flowers, enhanced maturity cycle and improve sex ratio by suppress the male flowers. Auxin 50-100 ppm has great influence on growth as well as ethrel improves the yield attributing parameters in cucurbits.
