  1. Plant Height (PH). Number of Leaves (NL). Leaf Length (LL). Leaf Diameter (LD). Pseudostem Diameter (PD). Data are presented as means from 4 biological replicates. Different letters indicate values significantly different at p ≤ 0.05.
  2. *Significant at 5%; **significant at 1%; ***significant at 0,1%, ns: no significant. All these values were performed on 56 plants per group.
