Lengths of longest roots of rice (‘Amaroo’) grown in aerated solution with high P (200 μm) and then transferred to aerated or stagnant nutrient solution at high and low (1·6 μm) P supply for 4 and 8 d

		Lengths of longest roots (cm)
P level	Culture	Initial	4 d	8 d
Low P	Aerated	34·8 ± 0·59	40·3 ± 2·17	45·2 ± 1·42
	Stagnant	34·8 ± 0·59	32·7 ± 0·67	32·5 ± 3·87
High P	Aerated	34·8 ± 0·59	37·4 ± 2·42	40·7 ± 4·87
	Stagnant	34·8 ± 0·59	35·6 ± 1·50	37·1 ± 0·95
F-test			O × P*	O × P*

Values are means of three replicates ± standard errors.l.s.d. for solution aeration and P interaction effects: 4 d, 3·04; 8 d, 2·62.

^*Significant at P < 0·05 for O × P based on F-test for solution aeration and P interaction effects.
