Application and prospect of plant growth regulators on tobacco

It is a great potential research field that the qualities of tobacco leaves are improved by plant growth regu-lators.At present,the regulating effects of plant growth regulators on the seed germination,the growth of seedlings,root activity,the potassium content of tobacco leaves,nicotine synthesis and the inhibition of axillary buds,and so on,have been studied at home and abroad.In the future,harmonizing the growth and development of tobacco plants and the metabolism balance of inclusion in tobacco by plant growth regulators,improving the quality of tobacco and reducing the residue of exogenous hormones in leaves by chemical regulation would be the further research directions.
