In 4 transgenic plants examined out there are two no bolting 检出的4株转基因植株中，有两株不抽薹。

Results showed that " bolting time " was the basic morphological index for heat resistant identification 结果表明，抽薹时间是理想的耐热性鉴定指标。

But the starting time and duration are very different from population to population , witn flowering being prior to sprouting in the population originated from jurong county 其中以引自于江苏句容的半夏居群抽薹最早，且具“先花后叶”特性。

The activities of pod and sod , contents of soluble protein , soluble sugar , proline and malonyldihyde were significantly correlated with the basic morphological indexes , and suitable to be applied as auxiliary indexes in heat resistant identification of head lettuce Pod和sod活性、可溶性蛋白和可溶性糖含量、脯氨酸含量及丙二醛含量等生理生化指标与抽薹时间显著相关，因而可作为结球莴苣耐热性鉴定的辅助指标。

Result and conclusion : there are obvious differences in sprouting , lamina spreading , bolting and " sprout tumble " , three times of " sprouting " and so - called " sprout tumble " and two fast - growing periods for plants in most of the populations in spring and autumn respectively were observed within a year , including mass bolting in may 结果与结论：半夏各居群在出苗、展叶、抽薹及倒苗期等生长节律方面存在着差异：大部分半夏居群在本试验栽培条件下具明显的3次出苗和3次倒苗现象，并且在年生长期内表现出春秋两个生长高峰期;从抽薹开花时间看，大部分居群在5月有1个抽薹开花高峰期，但具体起始和延续时间各居群间存在着较大的差异。

In order to provide the scientific basis for the good agricultural practice ( gap ) of sichuan bai zhi , rapd was firstly used to analyze the genetic polymorphism of different type from sichuan bai zhi and hangzhou bai zhi . the result showed that different color of petiole has not obvious relationship to whether to bolt or not and different localities have more influences on genetic diversity than different color of petiole 为配合川白芷生产质量管理规范化( gap )研究，本文首次采用rapd技术对川白芷生长过程中不同形态的四个类群及杭白芷进行基因组dna多态性分析，认为川白芷叶柄颜色的不同与是否抽薹无明显的相关性，而产地的差异对遗传变异的影响大于因其叶柄颜色不同所造成的影响。
