The trials were carried out in field experiment and artificial climate incubator. The sugar beet growth buds were treated at 1～3pairs of true leaves with gibberellin , autix , naphthaleneacetic acid and kinetin , and the plant growth regulating substances enhancing bolting of sugar beet in the first year and its doses were selected out. The sugar beet seedling induced by temperature and light were treated by abscisic acid , maleic hydrazide , uniconazole (S-3307) and paclobutrazol (PP333), and the plant growth regulating substances which make bolting reverse and their doses were screen out. The mechanisms of bolting and bolting reversing were discussed by examining the changes of endogenous hormones, activities of correlative enzyme to bolting, soluble protein, components of amino acid in the protein, components of fatty acid. The results were as follow
