FIGURE 4

Fluorescence quenching analysis performed in non-galled tissues of Matayba guianensis (Sapindaceae) and in galls induced by Bystracoccus mataybae (Eriococcidae) using a modulated fluorescence imaging apparatus (Handy Fluorcam PSI – Photo Systems Instrument, Czech Republic). (A) Imaging of NPQDN (instantaneous non-photochemical quenching during dark relaxation). (B) Imaging of NPQLss (steady-state non-photochemical quenching). GT, galled tissue; NGT, non-galled tissue; SD, standard deviation. Values followed by the different letters differ significantly by the Wilcoxon test.
