Results of averaged standard deviation of NNIF. Results of averaged standard deviation of NNIF for Koshihikari rice cultivar showing the effect of O3 under three experimental conditions of 0 nl l-1, 120 nl l-1, and 240 nl l-1 O3 exposures for three consecutive days. The error bars correspond to the SEs of the mean. Shown are means ± SE. The durations ‘Before’, ‘Within’ and ‘After’ are shown by separating with broken lines. For each treatment (CF, 120 nl l-1, and 240 nl l-1) six rice samples from Koshihikari cultivar was used. All together 18 samples were investigated.
