Summary Potato tubers contain undesirable steroidal glycoalkaloids (SGAs), which have evoked global concern in terms of feed and food safety due to their toxic effects humans. The cultivar Unica was exposed a combination light wounding. SGA content among different tissues analysed. Our results showed that contents subjected higher than intact stored darkness, the skin varied with time; however, flesh remained stable at relatively low level. wound tubers. Importantly, wounding were shown synergistic on tuber, only influenced within approximately 3 mm surface. study provides theoretical basis for reasonable safe consumption potatoes.
