Cytokinin sprays can help to keep cut flowers fresh. They delay aging by inhibiting protein breakdown, and stimulating RNA and protein synthesis.

Plant growth regulators (PGRs) or plant hormones square measure the crop protection chemicals that are made in plants or synthesized and applied to the plants in order to control its growth. In agriculture, PGRs have been used since decades to serve a spread of functionalities like elongating or shortening plant length (depending on the specified function), ripening of fruits and vegetables, producing stoneless fruits, control lodging in cereals, defoliating and boll opening in cotton plants and therefore on in numerous crops so as to boost the standard and yield of the several crops.
