| 摘要: |
| 利用Folin-Dianies法测定了中国野生葡萄7个种34个株系的种子和果皮单宁含量。结果表明，供试野生材料种子单宁含量为30～50 mg/g，其中复叶葡萄含量最高（平均为48.5 mg/g），刺葡萄最低（平均为31.5 mg/g）；果皮单宁含量大多小于种子单宁含量，其中秋葡萄果皮单宁含量最高（平均为78.0 mg/g），刺葡萄最低（平均为16.4 mg/g）。结果表明，葡萄种内株系间种子单宁含量差异性大，而种间果皮单宁含量的差异性大。 |

| Abstract: |
| By Folin-Dianies,the tannin contents of the seed and of the berry skin were determined with 34 clones of 7 Chinese wild vitisV.piaseckii were the highest (48.5 mg/g average),those in V.davidii were the lowest (31.5 mg/g average).The tannin contents of the skin were lower than those of the seed.Of all wild materials,the skin tannin contents in V.romanetii were the highest(28.0 mg/g average),and those in V.davidii were the lowest (16.4 mg/g averge).The seed tannin content differences among the clones in the same species were significant,and the skin tannin content differences were significant among the species. |
