Abstract
SUMMARY Standardized inoculations of the potato varieties Catriona and Doon Star over 6 years have shown that shortening the growth period, either by deferring planting or by removing the haulm prematurely, may considerably reduce susceptibility of the tubers to dry rot (Fusarium caeruleum). Although these treatments reduce dry‐matter content of the tubers, no direct relationship between this factor and susceptibility was established. High pre‐maturity susceptibility was confirmed at the time of flowering; as the haulm matured susceptibility decreased: when the haulm was dead tubers were resistant. Within a fortnight after any time of premature haulm removal, tubers became completely resistant and showed a decrease in sucrose content but not in content of reducing sugars. It is suggested that susceptibility in the immature tuber is closely related to the content of sucrose, which accumulates because of rapid translocation from the vigorously growing haulm. After harvest, tuber susceptibility slowly increased during storage, with an increase mainly in reducing sugars, but these two factors were not directly related. An application of 6 cwt/acre (753 kg/ha) of 12:12:18 NPK fertilizer to Catriona significantly reduced liability to infection. Additional nitrogen (6 cwt/acre ammonium sulphate) raised tuber susceptibility to that in a non‐fertilized plot: when sulphate of ammonia was the only treatment given, the tubers were significantly more susceptible than those receiving complete fertilizer.
