چکیده انگلیسی
Cold-induced sweetening (CIS) is a significant postharvest problem in processing potato (Solanum tuberosum L.) tubers. A rise in hexose sugar levels during cold storage results in a brown, bitter tasting and unmarketable product. We tested if potato microtubers (MicroT) can undergo CIS and if this corresponds to the CIS response in field-grown tubers (FieldT) with the hope of fast-tracking breeding programmes using a MicroT system. Using MicroT from potato genotypes representing a range of CIS response levels we have demonstrated that MicroT undergo CIS more rapidly than FieldT. Correlations of glucose:sucrose and hexose:sucrose ratios were highly significant between the two tuber types after cold treatment and these ratios are known to be good predictors of invertase activity, a key regulator of CIS. Correlations of individual sugars were non-significant before and after postharvest cold treatment.
