T. Wang(NCBI编号MH260617.1和MH260618.1)的亲缘关系较近,YHS-3次之,而YHS-1亲缘关系较远.田间数据结果显示,与另外2个品种相比,YHS-2具有花多且密,花期短以及块茎产量高的优良生产性状.建立6种苄基异喹啉型生物碱的快速检测方法分析3个品种中生物碱的含量.结果显示,YHS-2中各生物碱的含量显著优于YHS-1和YHS-3(p<0.05).表明3个品种中YHS-2更为适合浙江地区的生存环境,可作为目前延胡索浙江栽培的优质品种推广种植和使用.展开更多
Genetic diversity of Dendrolimus punctatus over five regions in Zhejiang Province were studied by ISSR-PCR.Thirteen primers were screened on the template of total DNA of the insects and total 74 bands of DNA fragments...Genetic diversity of Dendrolimus punctatus over five regions in Zhejiang Province were studied by ISSR-PCR.Thirteen primers were screened on the template of total DNA of the insects and total 74 bands of DNA fragments were amplified,of which the half(37 bands)was polymorphic.The genetic distance among the sampled populations ranged 0.114 4-0.475 4.The dendrogram was constructed based on their genetic distance using UPGMA method.The results indicated that there was low genetic diversity among the four populations from the main land,while the Dongtou population sampled from Dongtou island showed higher genetic diversity.展开更多
