Fig. 3 From:Peridermal fruit skin formation inActinidiasp. (kiwifruit) is associated with geneticlocicontrolling russeting and cuticle formation Auto fluorescence from toluidine blue stained sections of skins types seen in the backcross population. Scale bars represent 50 μM.AEpidermal skins with weakly fluorescing cuticle;Bskins with russeted suberized cells and trichomes;CandDskins with russeted suberized cells;Drusseted suberized cells covered with lignified cells. Suberin can be identified by bright blue fluorescence. Blue-green auto fluorescence indicates the presence of lignin. Auto fluorescence that occurred as a bright blue single layer above the L1 epidermal layer was taken as fluorescence of the cuticle Back to article page
