Sugar Metabolism in Stolon Tips of Potato during Early Tuberisation
Tuberisation in potato is accompanied by a substantial decrease in both total and reducing sugar levels in the stolon tip. There is a negative relationship between tuber growth and the ratio of reducing sugars : sucrose. However, a positive and statistically significant correlation exists between the ratio of glucose : fructose and the degree of tuberisation as determined by fresh weight measurement. This change in metabolism is confirmed by a pulse chase study using 14CO2.
