The number of embryos was scored per mm of root and per mm2 of leaf. Plantlets grown in vitro were submerged in the indicated solutions for 4 d before transfer to the culture medium. Water (a), 330 mM glycerol (b), 0.5 mM spermine (c) and 50 µM ABA (d) were used as indicated. The results obtained with leaves and roots are from independent experiments (n = 10 for leaves and n = 5 for roots). The percentage of explants exhibiting somatic embryos after 12 d (roots) or 20 d (leaf) of culture is indicated in brackets.
