Figure 4
Photomicrograph of cross-sections of P. palinuri leaves viewed through light (a), epifluorescence (b) and (c) microscopy. UV-microscopy evidenced phenolic compounds linked to the chloroplast membranes (blue fluorescence) and filling some cells in the epidermis, palisade parenchyma and spongy parenchyma around vascular bundles (yellow-orange fluorescence). Bars are 50 μm.
