饲用甜菜四倍体植株与二倍体植株相比，表现出叶片增大变厚，叶色浓绿，叶面多皱褶，叶柄粗壮等特点，可以将这些特点作为饲用甜菜四倍体田间初步筛选的指标。

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

In our study,two important lepidopteron pests,beet armyworm and cotton bollworm were surveyed for their endogenous piggyBac.As a result,endogenous piggyBac elements were found in these two insects,and one of the piggyBac elements isolated from the genome of cotton bollworm was intact and thought to be potentially active.1 Clonging and sequence analysis of piggyBac from beet armywormUsing PCR technique,with degenerate primers,a DNA fragment of piggyBac-like element was cloned from the genome of beet armyworm,spodoptera exigua hubner.The DNA fragment was 456bp in length,and the deduced amino acid sequence shares 50%- 78% similarity with other piggyBac elements from insects.But one stop code was found in this DNA fragment.

由于转座子很难用常规的RT-PCR和RACE技术进行克隆鉴定，故本研究在兼并引物PCR的基础上，利用inverse PCR和vectorret PCR技术，不仅调查了鳞翅目两种重要的农业害虫甜菜夜蛾和棉铃虫的內源piggyBac存在情况，同时克隆到了內源性的piggyBac转座子，并且从棉铃虫中获得了一个结构完整、具有潜在活性的piggyBac转座子HaPLE1.1甜菜夜蛾piggyBac转座子基因的克隆与序列分析采用PCR技术，利用兼并引物，从甜菜夜蛾基因组中克隆出一个內源性piggyBac类似因子的DNA片段，并命名为SePLE。
