PLANT GROWTH REGULATORS: THEIR IMPACT ON CUCURBITS

Cucurbitaceous crops are referred to as "cucurbits" in general.Cucurbits cover the most land in India and other tropical nations.Cucurbits are high in calories, minerals, and vitamins.Cucurbit seeds are prized for their high oil and protein content.To boost productivity and food safety, by adopting inputs such as plant growth regulators, Indian agriculture has become more mechanized and science-based; plant growth regulators have a faster influence on crop vegetative as well as yield.PGR administration in cucurbits stimulates growth by assisting in vine elongation, increases fruit setting, changes morphological and growth characteristics, and helps the plants tolerate disease-related difficulties.The application of GA 3 at low concentrations influences plant growth and boosts growth metrics such as the number of male flowers and the appearance of the first male bloom.Auxin stimulates development by increasing the number of branches and leaves.The use of ethereal altered the sex ratio by increasing the number of female flowers and suppressing male blooms, which increased the yield parameters. Exogenous application of PGRs has an influence on plant endogenous hormones, altering the plant's physiological processes.Various plant growth regulators in suggested concentrations promote faster growth, earlier blooming, a lower sex ratio, higher fruit output, and improved fruit quality.Generally, the growth regulator aids in the production of marketable fruit in a short period of time.Different PGR applications had a substantial effect on stem length, branch number, total number of flowers, fruiting, yield, and other yield contributing features.PGRS regulates physiological processes in cucurbit crop plants such as rooting, flowering, growth, sprouting, and ripening, and the usage of PGRS in cucurbit production has been proven to be favourable for yield and yield contributing features.
