*4.2. Measurement and Data Collection of Growth Parameters*

At harvest time, morphological parameters, seedling fresh biomass (g), seedling dry biomass (g), and seedling height (cm) were measured. The height (H), fresh weight (FW), and dry weight (DW) were determined on 15 seedlings, randomly selected within each container. The weight was expressed as micrograms per seedling. The dry biomass (DW) of the plants was obtained by putting weighed samples in a thermo-ventilated oven at 70 ◦C until they reached a constant weight. Stem and leaves were immersed in liquid nitrogen and kept at −80 ◦C for phytochemical analysis. The plant height/plant dry weight ratio (H/DW, cm·mg−<sup>1</sup> ) was also calculated. For all chemical analysis, three replicates were performed.
