Least square mean values (standard error in parenthesis) of leaf nitrogen content per unit mass (%) of seedlings grown under different light intensities

	Full sunlight*	45 % sunlight	12 % sunlight
Treatment mean (significance test P < 0·014)	1·59 (0·25)	1·75 (0·09)	2·11 (0·09)
Lansium	–	1·43 (0·13)	1·72 (0·13)
Durio	–	1·23 (0·13)	1·11 (0·13)
Hevea	2·62 (0·21)	2·71 (0·21)	3·21 (0·21)
Alstonia	1·30 (0·21)	1·62 (0·21)	2·40 (0·21)

Overall F-test of two-way ANOVA highly significant (P < 0·001), species × treatment interaction not significant (P = 0·09).

^*No data presented for Lansium and Durio, due to high mortality.
