摘要
为比较不同砂梨种质资源叶片总酚含量的多样性,对117份不同砂梨品种叶片的总酚含量进行测定和分析。结果表明,不同砂梨品种鲜叶中总多酚含量为8.67~32.29 mg/g,平均总多酚含量20.44 mg/g,变异系数22.92%,遗传多样性指数2.09。不同种质类型的平均变异系数为地方品种(23.81%)大于国内选育品种(23.63%)大于国外引进品种(19.03%),平均遗传多样性指数为地方品种(2.10)大于国内选育品种(1.82)大于国外引进品种(1.80)。
In order to compare the diversity of total phenolic content in leaves of different sand pear germplasm resources,the total phenolic content of 117 leaves of different sand pear varieties was examined and analyzed.The results showed that the total polyphenol content in fresh leaves of different sand pear varieties ranged from 8.67-32.29 mg/g,the average total polyphenol content was 20.44 mg/g,the coefficient of variation was 22.92%,and the genetic diversity index was 2.09.The average coefficient of variation of different germplasm types was local breed(23.81%)larger than domestic breeds(23.63%)than foreign introduced varieties(19.03%),and the average genetic diversity index is that the domestic varieties(1.82)of local varieties(2.10)are larger than the imported varieties(1.80).
