Figure 5
Ascorbate peroxidase (APX) and superoxide dismutase (SOD) activities in
rice leaves grown under different Pi application conditions. (a) shows
the results of the total, cytosolic, and chloroplastic APX activities
evaluated on the leaf area basis. The red, yellow, and green characters
above the bars indicate the statistical results of the total, cytosolic,
and chloroplastic APX activities, respectively. (b) shows the results of
the chloroplastic APX activities evaluated on the chlorophyll basis. (c)
shows the results of the total, Fe-, Mn-, and Cu/Zn-SOD activities
evaluated on the leaf area basis. The gray and blue characters above the
bars indicate the statistical results of the total and the Cu/Zn-SOD
activities. These results are expressed as mean ± SD (n = 3). Different
alphabets indicate significant differences among different Pi
application conditions (Tukey-Kramer’s HSD test, p <
0.05).
