- Total biomass, capture, and efficiency in the use of water and radiation and related traits. Results of the ANOVA (ns, not significant; *, significant at P ≤ 0.05; **, significant at P ≤ 0.01; ***, significant at P ≤ 0.001;). Cultivar × treatment and cultivar × year means and LSD (P ≤ 0.05) for the comparison of means
