【摘要】 目的探讨防风多倍体新种对于防风产量和质量的影响。方法以1年生,2年生防风的二倍体、多倍体新种作为采集样本,以其中含有的四种色原酮含量作为指数,用HPLC法进行测定。结果1年生多倍体防风四种色原酮含量低于二倍体防风16.5~24.0%,而2年生色原酮含量略高于1年生,并且产量高于二倍体18.1%。结论防风的多倍体新种能够提高防风的产量和质量,具有推广价值。更多还原

【Abstract】 Objective To study on the yield and quality for the newly specie of the Polyploid Saposhnikovia divaricata.Methods Collecting samples of polyploid and diploid in one-year-old growth and twoyear-old growth,respectively;determined contents by HPLC,with 4 kinds of chromes of the Polyploid Saposhnikovia divaricata as a marker.Results The content of one-year-old polyploid is less 16.5~24.0% than that of diploid,while the content is bigger in two-year-old than in one-year-old,and its yield is higher 18.1% than that of diploid.Conclusion It has spread value for Polyploid Saposhnikovia divaricata could increase the yield and quality.更多还原
