4个葡萄品种茎叶表面微结构的比较

用扫描电镜观察比较了超藤、藤稔、伊豆锦和先锋4个品种葡萄的新鲜茎叶表面细微结构的差异．4个品种葡萄的叶、茎、卷须和叶主脉的表面细微结构不同，各自具有独特的细微构造：先锋叶上表面主脉具有凹陷型的气孔；藤稔茎表皮细胞表面具有规则的凹陷；伊豆锦刚毛粗壮；超藤卷须表面的索条状纹饰呈波状．新品种超藤的叶、茎和卷须表面的微结构与其母本藤稔有着较显著的区别．4个品种葡萄茎叶表面细微结构存在的明显差异，为葡萄品种鉴别提供了更多的形态学依据．

Comparison of surface ultrastructure of stem and leaf in 4 varieties of Vitis vinifera

It was studied the differences of stem and leaf surface ultrastructure of 4 varieties of Vitis vinifera ： Superfujiminori, Fujiminori, Izunishiki, Pioneer. Fresh stems and leaves of 4 varieties of Vitis vinifera were observed by scanning electronic microscope （SEM）. There were differences on the surface ultrastructure of leaf, stem, tendril, the main vein and each grape had main vein of Pioneer; the epidermic cells of Fujiminori some special ultrastructures. There were sunk stoma on had inerratic dents ; the bristles of Izunishiki were thick and strong; the cord-like ornamentation of Superfujiminori were wavy-looking. Compared with Fujiminori, the surface uhrastructure of leaf, stem, tendril of Superfujiminori were different. Surface uhrastructure of stem and leaf would offer more morphological evidences for distinguishing different varieties of Vitis vinifera.
