Abstract
The effects of NaH2PO4, sucrose, activated charcoal, polyvinylpyrrolidone (PVP), and strength of MS medium were studied to optimize thidiazuron (TDZ)-induced direct somatic embryogenesis from leaf explants of Phalaenopsis aphrodite subsp. formosana. The results showed that full- and quarter-strength macroelements of MS medium were not suitable for direct embryo induction from leaf explants. Thus, a half-strength macroelement and full-strength microelements of MS nutrients plus full-strength of MS vitamins, 170 mg l−1 NaH2PO4, 1 g l−1 peptone, 3 mg l−1 TDZ, and 20 g l−1 sucrose are proposed as a suitably modified medium. In addition, PVP at 0.25 g l−1 significantly promoted direct embryogenesis on the cut ends of the explants, but activated charcoal at 0.5–1 g l−1 was inhibitory.
