湖南三种野生葡萄的生物学特性及花粉形态研究

Study on the Botanic Characteristic and Pollen Morphorlogy of Wild Grapes in Hunan

为了给湖南葡萄的品种改良提供可以利用的本地野生品种资源 ,对湖南省境内广泛分布的 3种野生葡萄资源毛葡萄、刺葡萄和华东葡萄的生物学特性及花粉形态进行了观察 .电子显微镜观察结果表明 ,毛葡萄、刺葡萄花粉形态和花粉表面特征相似 ,由此推断二者亲缘关系可能较近 。

Vitis quinquangularis Rehd.,V.davidii Foex. and V.pseudoreticulata W.T.Wang are widely dispersed in Hunan Province. The results obtained through SEM show that pollenmorphorlogy and superfical characteristics of V.quinquangularis Rehd. and V.davidii Foex. are similar to each other,while those of V.Psedoreticulata W.T.Wang are different from the two. It is concluded that V.quinquangularis Rehd. and V.davidii Foex. might have closer relationship.
