Cerium was supplied into the nutrient solution as CeCl3 7H2O. Means significantly different at P ≤ 0.05. PH: plant height; RL: root length; NT: number of tillers; RV: root volume; SFBW: shoot fresh biomass weight; RFBW: root fresh biomass weight; SDBW: shoot dry biomass weight; RDBW: root dry biomass weight; aaS: amino acids in shoots; aaR: amino acids in roots; TSS: total sugars in shoots; TSR: total sugars in roots; CeS: Ce concentration in shoots; CeR: Ce concentration in roots. Numbers followed by an asterisk (*) indicate statistically significant differences between the compared variables (P ≤ 0.05).
