The Observation on Stoma in Leaves of Fuji Apple Strains

This paper adopted acid dissociation method to observe stoma in leaves of Fuji Apple strains thereby to appraise Fuji apple sports and various variance characters.The result showed that the changes of stoma density ranged from 91~173 unit·mm-2.Guard cell length ranged from 25.8~32.4 μm.Guard cell width ranged from 18.4~24.2 μm.Guard cell width in sports variety was longer than in original variety.The result through cluster analysis showed that stoma density in spur type sports variety was less than in original variety.It could appraise the spur type sports variety.The sports of coloring up type and early ripening type and big fruit type distributed in each three cluster.They could not be appraised by stoma characters.
