The stomatal density, stomatal area, size of stoma and stomatal apparatus of 25 Chinese bayberry(Myrica rubra Sieb.et Zucc)leaves in southeast of Zhejiang province Taizhou.,Wenzhou.,Ningbo and Shaoxing The stomatal density, stomatal area, size of stoma and stomatal apparatus of 25 Chinese bayberry(Myrica rubra Sieb.et Zucc)leaves in southeast of Zhejiang province Taizhou.,Wenzhou.,Ningbo and Shaoxing were examined by optical microscope. The results showed that stomata of all varieties were of parallel type; stomatal density ranged from 500-1200 No./ mm2, and major cultivars, such as Dongkui, Biqi and Ding’aomei presented a low density level; size of stomatal area concentrated in 50μm2 at a range of 40-80μm2; Weizhi No.1 had the largest major and minor axis of stomatal apparatus size, while Wenzhoutumei had the smallest; the major axis were bigger than the minor axis of all stoma size. Cluster analysis of stomatal density, stomatal area, size of stoma and stomatal apparatus by center of gravity method, classification from a distance of 0.5, it can be divided into five categories A cluster analysis showed that it was, to a certain extent, practicable to distinguish the varieties by using stomatal similarity. However, molecular biology and morphology methods were also needed for precise study of the genetic relationships.
