light intensities during the growing
period ranged between 250 and 400 mol m−2 s−1 PAR and
relative humidity from 60% to 80%. For the nutrient solution experiment,
primed seeds were germinated for 7 days in rolls of filter
papers moistened with distilled water before transfer into pots containing
400 mL of aerated nutrient solution (1 plant per pot with 4
replicates per treatment).
