WAgNO3; NS: not significant (p > 0.05); zsignificant at * p ≤ 0.05, **p ≤ 0.01, and ***p ≤ 0.001; yL: linear; xQ: quadratic in regression analysis. Values are the means of five samples (n = 5). Different letters are significant differences among treatments at p ≤ 0.05, according to Tukey's test. SFWP: Shoot fresh weight/plant; RFWP: Root fresh weight/plant; SDWP: Shoot dry weight/plant; RDWP: Root dry weight/plant; LDWP: Leaf dry weight/plant; FDWP: Flower dry weight/plant, and stem DWP: Stem dry weight/plant.
