From reading and inference over the years, I've come to this basic model for 'ripening': (Confidence level is not high.)
- Photosynthesis in the leaves produces sugars. These are available to nearby fruits. This is good.
- There's a process in the fruits that converts sugars to starches. This is not good for flavor. Heat and sunlight promote this process. Ergo, tomatoes should be shielded from the sun.
Is this true/sorta true/bogus?
If (sorta) true, does it apply broadly - say to squash, cantaloupes, peppers, ...?
