Fig. 2.

Total tocopherol (A), γ-tocopherol (B) and α-tocopherol content (C) in the flavedo of non-covered (NC) and covered (C) fruits of Star Ruby grapefruit, at the covering time (CT), harvest (H) and during postharvest storage at 2 °C for up to 8 weeks. Letters indicate significant differences in tocopherol contents among dates for each fruit condition, capital letters for NC fruit and lowercase letters for C fruit (p ≤ 0.05, Tukey test). Asterisks indicate significant differences between NC and C fruit (p ≤ 0.05, t-test). Results are expressed as µg/g of fresh weight.
