Several variables, e. g. cell shape, cell arrangemnt in the peel tissue, and proportion of the cell wall area to the radial section area were measured at harvest in 14 apple culti-vars. The data were analyzed in relation to : 1) the 4 indices of susceptibility to fruit cracking, 2) the distributions of density of fracture on a fruit surface, 3) the occurrence of fine cracks and 4) the physical properites of the peels.
It was evident from the analysis that cultivars possessing the following characters were more susceptible to fruit cracking : a) flatter cells in the outer cell layers, b) larger tangential and radial cell diameters in the inner and the outer layers, c) larger cell surface areas, d) larger differences in cell surface area between the two layers, and e) higher percentage of cell wall area stained by fast green or safranine in the radial section area.
