  1. Three seedlings per bottle were cultured in phosphorus saturation solution (1000 μM KH2PO4) to the three-leaf stage, followed by low phosphate stress solution (5 μM KH2PO4) for an additional 25 days to the six–seven-leaf stage. Values represent the means of nine seedlings ± SD. Values with different letters within a row are significantly different (P < 0.05) by multiple comparison analysis
