Effects of postharvest SA treatment at 0, 1, 2 and 4 mM on the browning index(BI) of anthurium cut flower storage at 4 ± 0.5◦C for 21 days. Data shown are meanvalues of n = 3 and the error bars represent standard errors of the means. Tukey testat P = 0.05 level.3. Results3.1. Chilling injury symptomsSpathe browning increased during storage at 4◦C and theincrease was delayed by postharvest SA treatment (P < 0.01;Figs. 1 and 2). Treatment with postharvest SA at 2 mM resulted ina lower chilling injury score (Fig. 1; P < 0.01) and browning index(Fig. 2; P < 0.01), while postharvest treatment with SA at 4 mMresulted in higher chilling injury scores. Thus, SA effects on thechilling injury of anthurium cut flowers are concentration depen-dent. Based on these results, 2 mM SA for postharvest treatmentwas chosen for further biochemical analyzes. The spathe brown-ing in control anthurium cut flowers starts after 4 days storage at4◦C, which show shortest vase life, 16 days. But, in anthurium cutflowers treated with 2 mM SA, spathe browning starts after 8 daysstorage at 4◦C, which show longest vase life, 27 days (Table 1).3.2. Electrolyte
