Comparison of in vitro and in vivo inflorescence of common cockscomb (Celosia argentea var. cristata)

摘要

Inflorescence of common cockscomb (Celosia argentea var. cristata) was induced in vitro from plantlets regenerated from nodal explants cultured for 5 weeks on semi-solid basal MS medium supplemented with or without 0.5 mg/1 benzyladenine under aseptic and light conditions. In vitro inflorescence of 12-week-old plantlets was compared with that formed under natural conditions. Florets from both sources had the same number of floral parts and exhibited similar characteristics (floret shape and percentage of pollen germination). However, the florets formed in vitro were obviously smaller than those formed under natural conditions.
