FIGURE 1

Plant biomass allocation to roots (means ± s.e., n = 10) of root-flooded Alternanthera philoxeroides subjected to nutrient (A) and dissolved oxygen (B) treatments. The set-up of nutrient and dissolved oxygen levels was the same as that in Table 1. Within each treatment, the significant difference between treatment levels is indicated by different letters (Duncan’s multiple range test, P < 0.05).
