Fig. 1From: Cotyledonary somatic embryo is one kind of intermediate material similar to callus in the process of in vitro tissue culture from Rosa hybrida ‘John F. Kennedy’Different regeneration results during the SPC culture of Rose hybrida ‘J. F. Kennedy’. (a) Cotyledonary somatic embryos (CSE) propagation; (b) Single-piece cotyledonary somatic embryos explants (SPC initial material); (c) Single bud formation from SPC explants (SBF type material); (d) The regenerated seedling via SBF approach; (e) Multiple buds formation from SPC explants (MBF type material); (f) Multiple buds proliferation via MBF approachBack to article page
