IN VITRO SHOOT INDUCTION AND PLANT REGENERATION FROM FLOWER BUDS OF PAPHIOPEDILUM 707
micropropagated clones from hybrid crosses have neither of
these two basic requirements. In addition, the germination
rates of Paphiopedilum seeds are generally low in comparison
to other commercialized orchids, and the seedlings
need a long time to reach the maturation stage before
flowering (Arditti et al. 1982).
