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

The optimal condition of regeneration system in vitro culture of lettuce was Murashige and Skoog\'s medium supplemented with 0.2 mg/L 6-benzylaminopurine,0.1 mg/Lα-naphthaleneacetic acid,and using the cotyledons of seedling with 2～3 days-old as explants.The interaction of BA×NAA played an important role in the expression of regeneration responses.

生菜离体培养再生芽的最优分化条件组合为MS附加BA 0.2 mg/L，NAA 0.1 mg/L，外植体为2～3 day的子叶；其中，BA及NAA的交互作用对植株再生有重要的影响。

GUS expression activated by the OsGT1 promoter was strongly stimulated by NaCl and low temperature, moderately by abscisic acid and naphthaleneacetic acid, and not at all by salicylic acid and gibberellic acid.

表明水稻OsGT1基因主要在根和花中表达，与水稻抗盐与低温胁迫相关。

Methyl α-naphthaleneacetate was synthesized by using α-naphthaleneacetic acid and methanol as raw materials and solid superacid TiO2/SO42- as a catalyst.

以固体超强酸TiO2／SO42-为催化剂，研究了α-萘乙酸与甲醇的酯化反应，探讨了催化剂种类、用量及活化温度等反应条件，发现固体超强酸TiO2／SO42-对α-萘乙酸与甲醇的酯化反应具有较高的催化活性，并使后处理简化。

After 5～7d of culture,adventitious buds appeared directly from explants without any intervening callus on Murashige and Skoog medium supplemented with different concentrations of N-6-benzyladenine alone or together with 0.5mg/L α-naphthaleneacetic acid.
