我国野生葡萄分类研究

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.

Studies on the Taxonomy of Wild Grape Species Native to China

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.
