Phalaenopsis Hand Pollination: Column Anatomy, Pollinia Transfer, and Seed Pod Development

Orchid Flower Anatomy: The Column

Orchids fuse male/female parts into a column (cylindrical center structure). Key parts:

• Anther cap (tip) — covers pollinia (pollen masses).
• Pollinia — waxy pollen packets with sticky ends.
• Rostellum — sterile barrier preventing self-pollination.
• Stigma — sticky female surface behind rostellum.

Pollination Procedure

1. Timing: Early—shortly after bud opens.
2. Lift anther cap with toothpick → pollinia adhere.
3. Separate pollinia from cap.
4. Push each pollinium's sticky end onto stigma.
5. Use ALL pollinia from donor flower.
6. Remove recipient's own pollinia first to prevent selfing.

After Success

• Pedicel swells in weeks → seed capsule forms.
• Maturation: 3-6 months.
• Sterile flask culture required for germination (separate complex topic).

Lab Advantage

Your mycology lab access (sterilization, media prep) is perfect for the flask phase. Start with pollination practice; master sterile technique next.
