Fig. 4From: Ecotoxicological assessment of cigarette butts on morphology and photosynthetic potential of Azolla pinnataA heat map was used to illustrate the relative variability of multiple photosynthesis-related parameters obtained from the JIP test on A. pinnata plants under CBs stress. The data was collected for varying concentrations (0-40) after 24 hours, with red indicating lower values (1%), yellow indicating medium (50%), and green indicating the highest values (100%). Prior to color coding, all data was normalized to maintain unbiased results within a range of 1-100 for the parameter valuesBack to article page
