Scanning electon microscopy of sweet potato roots ( Ipomoea batatas , cv. Jewel) revealed that tissue exhibiting the physiogenic disorder called hardcore appeared to possess more rigid intact cell‐cell junctures than normal tissue. Cooking grossly distorted the tissue and cellular integrity of normal sweet potato and caused noticeably less perturbation of cell‐cell junctures in hardcore tissue. The results support the hypothesis that hardcore is caused by the deposition of heat stable supporting material in the walls or middle lamella of regions of parenchyma tissue although the underlying reason(s) for the differences in appearance are not revealed by this study.
