The decision proved providential, as Leopold, whose book introduced him to growth regulators, taught advanced plant physiology at the university and eventually came up with a paper on Ethrel, with the main ingredient
ethephon, as a plant growth regulator.
There are three major areas to be researched in banana post harvest handling, a) to standardized ripening regimes (temp, ethylene,
ethephon, I MCP etc) b) post-harvest treatments to minimize rots (anthracnose and stem end rots) and c) physiochemical studies (finger drop and finger splitting) after ripening.
