Abstract: The grapevine leaf stomatal characteristics research was conducted on 19 wild vitis species or subspecies native to China.The results showed that the stomata longitude had an important part in the grapevine classification among the different vitis species,and that the relative density of stomata (the ratio of the relative area of all stomatal complex to the total leaf area) was linearly correlated with the leaf longitude within one species and the stomata density was negtively correlated with the stomata longitude.All the observed stomatal complexes types were anomocytic ones.
