Effet de l'entreposage frigorifique sur le potentiel des tubercules de pommes de terre (Solanum tuberosum L) à stocker des glycoalcaloïdes et des chlorophylles lors de l'exposition à la lumière, avec modélisation par réseaux neuronaux artificiels.

The effect of prior storage on the potential of potato tubers (Solanum tuberosum L) to accumulate glycoalkaloids and chlorophylls during light exposure, including artificial neural network modelling.

Résumé

Potato tubers of four cultivars (Brodick, King Edward, Pentland Dell and Record) were stored under commercial conditions and exposed to light for up to 10 days after 0, 10, 20 and 30 weeks. These were analysed for photosynthetic pigment and glycoalkaloid content. There was no significant alteration in either tuber chlorophyll or glycoalkaloid content during dark storage. All cultivars greened in response to light exposure, but only three exhibited a significant increase in glycoalkaloid concentrations during this exposure. A number of artificial neural network models of the results were produced.
