Figure 1

Leaf disk appearance depends upon light exposure during post harvest storage. Representative photographic images of kale (A), cabbage (B), lettuce (C), and spinach (D) leaf disks after varying number of days (number of days indicated at left) of storage at 22°C under 12-hours light/12-hours darkness (Light/Dark Cycles, LD), constant light (LL), or constant dark (DD), or at 4°C under constant dark (Refrigerated, 4CDD). Spinach disks disintegrated after 3 days when stored under constant darkness and therefore images were not available. (Scale bars, 1 cm).
