Test at 29 °C. (A) Photographs of untreated nubbin as well as those treated with Z/P 6/4 without curcumin and with Z/P 6/4 at 29 °C for 36 h. The black bars indicate 1.2 cm. (B) Concentration of chlorophyll a for the control, Z/P 6/4 no curcumin, Z/P 6/4 samples at 29 °C. *p < 0.05 Z/P 6/4 vs CTRL (24 h P = 0.012; 36 h P = 0.0001). (C) Concentrations of chlorophyll c2 for the control, Z/P 6/4 no curcumin, and Z/P 6/4 samples at 29 °C. *p < 0.05 Z/P 6/4 vs CTRL (24 h P = 0.0001; 36 h P = 0.0001). (D, E) Activities of CAT and SOD, respectively, for the control, Z/P 6/4 no curcumin, Z/P 6/4 samples at 29 °C.
