Plantlet regeneration from cell line 1-3-5 of P. massoniana. (A) Somatic embryo regenerated plantlets on rooting medium for 2 months, developed white root tips. Scale bar = 1.0 cm. (B) Plantlets regenerated under light conditions, showing well-developed shoot and roots (4 months). Scale bar = 1.0 cm. (C) Percentage survival and rooting of plantlets after different maturation treatments on somatic embryos (combined treatments of different concentrations of abscisic acid (ABA), poly-ethylene glycol 8000 (PEG), activated carbon (AC) and maltose) of P. massoniana. (D) Survival and rooting rates of plantlets after maturation treatment with different concentrations of PEG (70, 90, 110, 130, 150 or 170 g/L) on somatic embryos of P. massoniana. Data represent the mean ± SD of replicates. Different letters above the bars of the same color indicate significant differences ac-cording to ANOVA and Duncan’s test (p < 0.05).
