Table 2.

Adventitious root and tiller numbers of rice (‘Amaroo’) grown in aerated solution at high P (200 μm) (initial condition) and then transferred to aerated or stagnant nutrient solution at low (1·6 μm) or high P (200 μm) supply for 8 d

Condition		Adventitious root numbers (roots per plant)	Tiller numbers (tillers per plant)
Initial		55 ± 2·1	3·9 ± 0·3
Low P	Aerated	142 ± 18·4	10·0 ± 0·9
	Stagnant	161 ± 9·8	6·7 ± 0·6
High P	Aerated	143 ± 24·0	12·0 ± 1·0
	Stagnant	176 ± 7·5	8·0 ± 0·0
F-test		O*	O* and P*

Values are means of three replicates ± standard errors. l.s.d. for solution aeration effects: adventitious root numbers, 22·52; tiller numbers, 0·71, and for P effects on tiller numbers, 0·71.

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