Influence of different phosphate treatments on sucrose, starch and chlorophyll contents

Inbred lines	P treatment	Sucrose content (mg g-1 DW)	Starch content (mg g-1 DW)	Chorophyll content (mg g-1 FW)
Qi319-96	+P	46.61 ± 1.22a	200.22 ± 1.45b	2.54 ± 0.18a
	-P	31.51 ± 1.32c	210.34 ± 1.56a	1.47 ± 0.16c
Qi319	+P	40.84 ± 1.33b	189.25 ± 1.48c	2.13 ± 0.15b
	-P	25.63 ± 1.24d	209.39 ± 1.55a	0.98 ± 0.09d

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
