摘要 The rough extent of leaf surface may be described by protruding of waxes which like as wart and of stomatal aperture and of width of the cuticular ledge around guard cells. Because the morphology of the leaf surface has obviously similar itseIf, so one can use the theory of the fractal dimension to deal with the problems of leaf surface rough. The paper studied the rough extent and the result showed: with the leaf growing up, the waxes accumulate more and more, the leaf surface is more rough and the dimension is larger. The dimension D which indicates the rough extent of warts protruding is about 2. 10-2.20 on the above epidermis; On the beneath epidermis the dimension D of stomatal opening protruding is about 2.00-2.24, Maximum width L of cuticular ledge is about 1.0-7.4μm.
