Effects of Pi deficiencies on APase activity and anthocyanin content in Zygophyllum xanthoxylum.

	Treatment	APase activity (μmol min−1g−1 FW)		Anthocyanin content [A532-(0.24*A653) g−1 FW]
		Shoot	Root	Shoot
1D	CP	1.83 ± 0.09	1.43 ± 0.09	0.50 ± 0.04
	-P	2.05 ± 0.15	2.02 ± 0.06*	0.57 ± 0.02
10D	CP	1.79 ± 0.14	1.36 ± 0.02	0.52 ± 0.02
	-P	1.93 ± 0.13	2.59 ± 0.04*	0.73 ± 0.03*

Data between treatments were tested with a t-test, at P < 0.05. Data are means ± SE, n = 5; Asterisks indicate significant differences (*P < 0.05) between CP and -P treatment.
