Specifically the fruits and plants treated are apples, such as Red Delicious and McIntosh, grapes such as Emperor, blueberries such as Vaccinium macrocarpon AIT, and poinsettias such as Euphorbia pulcherrima V-14. The fruits and plants are pref. exposed to the blue and red light of high intensity discharge lamps or fluorescent lamps for 1-4 hrs. daily at night for up to 40 days before harvesting. The lamps have an intensity of 1-200 milli watts/sq.cm. and the emissions have peaks at 448 nm for the blue light and 660 nm for the red light. In an alternative process, apples that have been picked are stored in the cold and exposed to red light continuously for 4 days. |
