Colour as indicated by NDVI (dotted lines) and NAI (full lines) index of MG (A) and R (B) tomatoes during cold storage at 2 or 12 °C (blue area) and subsequent shelf-life at 20 °C (white area). Blue, green, red and purple lines and symbols indicate 2.5, 5, 21 kPa O2 (low oxygen control) applied during storage at 2 °C and 21 kPa O2 at 12 °C (temperature control), respectively. The NDVI or NAI with indicated standard error is shown for five individual tomatoes (repeated measure over times). LSD values (p < 0.05) are indicated per panel.
