The productive capacity of a potato seed tuber within a cultivar can be manipulated and controlled. Since pathologists and Potato Seed Certification Services have made tremendous progress in controlling seed borne disease, greater effort can now be devoted to improving the physiological productive capacity of seed tubers. One of the most important factors influencing potential capacity is physiological age of seed as influenced by chronological age. In most temperate production areas the chronology of seed production, harvesting, storage, and replanting cannot be altered economically or logistically as practiced in Japan. Therefore, other methods of manipulating physiological age are being explored. Temperature of the growing and storage environment and temperature conditions after replanting can influence seed behaviour. Rate of physiological aging under various environments varies with cultivars.
