Micropropagation of Phalaenopsis Blume

Area of Science:

• Plant Biotechnology
• Horticultural Science
• Orchid Propagation

Background:

• Phalaenopsis orchids are economically important ornamental plants.
• Efficient regeneration protocols are crucial for mass propagation and conservation.

Purpose of the Study:

• To establish a high-frequency regeneration protocol for Phalaenopsis orchids.
• To optimize conditions for protorm-like body (PLB) induction and plantlet development.

Main Methods:

• Young leaf segments cultured on (1/2) MS medium with BA, NAA, coconut water, peptone, and activated charcoal.
• Incubation under controlled temperature and light conditions.
• Subculturing and sequential media modifications for PLB proliferation, shoot elongation, and plantlet formation.

Main Results:

• Protorm-like bodies (PLBs) induced within 12 weeks.
• PLBs proliferated and formed shoots within 8 weeks on modified media.
• Regenerated plants acclimatized and bloomed within 2 years.

Conclusions:

• The developed protocol enables efficient, high-frequency regeneration of Phalaenopsis.
• Optimized media and culture conditions support successful PLB and plantlet development.
• This method is suitable for large-scale propagation of Phalaenopsis orchids.
