Biomass, N content, transpiration and 15N tissue concentration and recovery of sugarcane and related species after 5 weeks growth with adequate N supply.

Nitrate content and relative 15N incorporation of these plants is shown in Figure 4 C, D. ANOVA and Tukeys post hoc test (Paindicates significant differences in biomass, transpiration and N content between genotypes.Aindicates significant differences in 15N concentration between genotypes supplied with 15NH4NO3, and between genotypes supplied with NH415NO3 for each tissue type.*indicate significantly lower 15N concentration within genotype when supplied with NH415NO3 compared to 15NH4NO3. Data represent mean n = 8 for biomass, N content data and n = 4 for 15N data.
