| 摘要: |
| 采用冰冻切片法对中国野葡萄10个种39个株系成熟浆果色素细胞特征进行了研究，结果表明，野生种表皮色素细胞多为6层，刺葡萄为8层或10层，下表皮细胞色素极易褪去，因而其色素细胞层数难以确定，供试材料色素颜色为红色及紫红色两类，但以含红色的材料居多，紫红色色素较红色色素更易褪去，对于同一材料的浆果，表皮及下表皮均为同一种颜色，只是色素深浅存在差异，绝大多数野生种成熟浆果色素细胞颜色很深。 |

| Abstract: |
| By freeze-sectioning,the characteristics of pigment cells of the ripe berries were described with 39 clones of 10 vitis species native to China.The results showed that there were 6 cell layers in the berry cuticule of most wild species,and the cell-layers in V.davidii were 8 or 10.The pigment in the sub-cuticule cells decolored quickly,so the exact numbers of the pigmented-cell layers were rather difficult to describe.Of all the studied materials,two kinds of color about the pigment cells were observed,and the one was red;the other one was purplish-red.And,the berry pigmeni-cell color of most species was red.The purplish-red decolored faster than the red.Of the same material,the berry pigment cell colors of the cuticule and the sub-auticule were the same,only color deepness was different between them.The pigment-cell colors of the ripe berries of most wild species were very deep. |
