The objectives of this study were to develop a modified chemiluminesence technique for apple and other fruit tissue by
examining the efficiency of PVP, PVPP and charcoal to remove the interference compounds in the measuring system; establish optimal chemiluminesence measuring conditions for determining H2O2 in apple fruit tissues under various physiological conditions; and compare the developed chemiluminesence technique with the OXIS kit. This study provides optimized protocol for universal chemiluminescence (CL) method for H2O2 determination in various plant tissues which uses PVPP for removing contaminants.
