Fig. 1.

Sugar contents (%, on fresh basis) of raw and baked TNG57, TNG66, and TNG73 sweet potatoes (black circle: fructose; white circle: glucose; black down pointing triangle: sucrose; white triangle: maltose; black square: F+G+S+M; Markers of fructose and glucose were overlapped. Vertical bars represented the SD, and when absent, they fell within the area of the symbol.). For each sweet potato cultivar, a and c represented the ambient storage condition (23.8 ~ 28.4 °C and 77.1 ~ 81.0 % of relative humidity), and b and d represented the 15 °C storage condition. Each observation was a mean of 6 replicate experiments (n = 6)
