Summary
The frequency of PMTV-spraing and TRV-spraing increased during storage in several cultivars. The only exception was cv. Saturna, where a decrease was observed in 1992. A spraing inducing treatment of one week at 18 °C followed by one week at 8 °C immediately after an early harvest increased the frequency and provided a rough estimate of the development of spraing in untreated tubers during storage. Under most circumstances wound healing at 25 °C compared with 15 °C resulted in a lower frequency of spraing during the storage period. The date of harvest had an important influence on development of spraing during storage and on the effect of post harvest temperature treatments. Therefore, physiological processes that induce or erase spraing are strongly related to tuber maturity. The mechanisms controlling development of symptoms seemingly are identical for the two spraing inducing vira.
