Figure 2

Visual evaluation of Rosanna tubers from experiment 1. Samples labeling is as described in legend of Figure 1 . Visual evaluation of tuber appearance was performed 24 h after harvest (A) and after 1 month of storage (B). Values are averages of six replicates with SE. Each replicate consisted of 12 tubers. Visual index was determined on a scale of 1 to 5: 5 = good skin quality, 1 = low skin quality, by a panel of four individuals who rate commercial products routinely. Data were analyzed for statistical significance by Student’s t-test; different letters indicate significantly different values (P < 0.05).
