Figure 1
Growth phenotypes of rice plants grown under different inorganic phosphate (Pi) application conditions. (a) shows representative plants grown under different Pi application conditions at the 70th day after germination. White bars indicate a scale of 10 cm. At this stage, plant height (b) and chlorophyll content in leaf blade (c) were examined. (d) shows the dry matter of leaf blade, leaf sheath, and root in rice plants grown under different Pi application conditions. The results are expressed as mean ± SD (n = 6-8). Different alphabets indicate significant differences between different Pi application conditions (Tukey-Kramer’s HSD test, p < 0.05).
