我国野生葡萄分类研究

Studies on the Taxonomy of Wild Grape Species Native to China

运用P.Galet方法,对分布于我国的葡萄属植物10个种的叶片进行了研究,并对叶片的数量化性状进行了聚类分析.结果表明:(1)供试10个种的叶片形态种间差异较大.(2)利用叶片性状进行聚类分析,可将10个种分为三大类群.(3)根据叶片的多型性,毛葡萄、复叶葡萄是较为原始的种类.(4)华中地区可能是我国葡萄属植物种的起源地,也可能是世界上葡萄属植物的重要起源地之一.

The leaf characters of 10 species of genus Vitis native to China were studied with the P. Galet method and clustering analysis for their classification. Results showed: The size and shape of the leaves of these species varied greatly, it could be classified into 3 groups. It was considered that V. quinquangularis Rehd. and V. piesazkii Maxim, were the primitive species among 10 species, and the central China was the orignat-ed place of China grape species. The latter was also considered as one of the important origin center of genus Vitis in the world.
