Do apples rot faster in light or dark?
Rotting, rather that ripening, is cause by bacteria or fungi. Neither of these organisms are light dependent. However the temperature will effect the rate of the apple’s decomposition. Fruit ripening is strongly effected by light. Phytochrome regulation of pigment production and acidity level is effected by the amount of shade the fruit receives. http://www.pubmedcentral.nih.gov/article… http://abstracts.aspb.org/pb1997/public/… http://jxb.oxfordjournals.org/cgi/conten… http://www.ajevonline.org/cgi/content/ab… The apple’s color at the peak ripeness is controlled by the amount of pigment it creates as it ripens.
