| 摘要: |
| 为比较柿种质资源间黄酮类化合物和多酚含量的多样性, 对111份柿资源叶片中槲皮素、山奈酚、粗黄酮和多酚进行测定和分析。结果表明, 柿种质资源间槲皮素、山奈酚、粗黄酮和多酚含量存在丰富的多样性;除槲皮素外, 不同柿地域来源间山奈酚、粗黄酮和多酚均表现出显著(P<0.05)差异性, 而不同柿类型间只有山奈酚显示出显著(P<0.05)差异性;聚类结果显示柿种质资源可分为四大类群, 其中类群Ⅳ为黄酮类化合物和多酚高含量的柿种质资源类群, 共有21份资源, 其为柿资源的选育提供了宝贵的育种材料。 |

| Abstract: |
| The concentrations of quercetin, kaempferol, crude flavonoid and polyphenols in the leaves from 111 persimmon germplasmss were determinated.The aim was to study the diversity of flavonoids and polyphenols in leaves of persimmon germplasm.The results indicated that there were abundant diversities in quercetin, kaempferol, crude flavonoid and polyphenols.The different leaves of geographical persimmon had significant amounts of kaempferol, crude flavonoid and polyphenols(P<0.05).However, the significant difference was only detected in the content of kaempferol from the leaves of different persimmon types(P<0.05).The result of cluster analysis showed that persimmon germplasms were divided into four groups.Twenty one germplasms in group Ⅳ had high contents of flavonoids and polyphenols, which could provide precious breeding materials for breeding persimmon germplasm. |
