The effect of white, red, and blue lights on postharvest longevity, chlorophyll content and stomatal aperture in cut leaves of Zantedeschia aethiopica Spr. and Hosta Tratt. ‘Undulata Erromena’ was studied. Red light doubled leaf vase life in Zantedeschia, delayed chlorophyll degradation, and decreased the stomata aperture. Blue light prolonged leaf longevity in Hosta delaying chlorophyll loss but without affecting stomata.
