Fig. 3From: Peridermal fruit skin formation in Actinidia sp. (kiwifruit) is associated with genetic loci controlling russeting and cuticle formationAuto fluorescence from toluidine blue stained sections of skins types seen in the backcross population. Scale bars represent 50 μM. A Epidermal skins with weakly fluorescing cuticle; B skins with russeted suberized cells and trichomes; C and D skins with russeted suberized cells; D russeted 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 cuticleBack to article page
