Each value was expressed as mean ± standard deviation. SG, seed germination; LL, leaf length; LW, leaf width; SH, seedling height; BL, branch length; SD, stem diameter; NB, number of branches per plant. Within columns, means ± standard deviation followed by the same letter are not significantly different at P = 0.05.
