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

本研究通过田间试验和人工气候箱培养相结合的方法，在甜菜幼苗1~3对真叶时利用赤霉素、生长素、奈乙酸和激动素等生长调节物质处理茎生长点，筛选促进甜菜当年抽苔的植物生长物质及剂量；同时利用脱落酸、马来酰肼、烯效唑（S-3307）和多效唑（PP333）等处理经温光诱导当年抽苔的甜菜幼苗，筛选对当年抽苔逆转有效的种类和剂量，并通过测定内源激素含量、相关酶活性、可溶性蛋白质含量和氨基酸组分及脂肪酸含量及其组分的变化，探讨甜菜当年抽苔和抽苔逆转的机理，得到如下结论
