“…However, normalization of the results indicated a marginal increase in O(2) production per time and per projected leaf area for the HiNH(4) (+) crop during the exponential growth phase, in line with a higher shoot chlorophyll content. Mineral analysis demonstrated that the biomass content of NH(4) (+) and NO(3) (-) varied in line with the nutrient solution composition. …”
