The effect of harvest time on the accumulation of reducing sugars during storage of potato (Solanum tuberosum L.) tubers: Experimental data described, using a physiological based, mathematical model
- 217 Downloads
The physiological based mathematical model describing the storage behaviour of potato (Solanum tuberosum) tubers was examined to determine its ability to explain the changing storage behaviour as a function of harvest time for ten different cultivars. Between 90 to 98% of the observed variance was accounted for. This confirmed the models concept that the maturity at time of harvest determines the storage behaviour through the initial amount of the enzyme (or enzyme system) responsible for cold induced sweetening.
