Carica weberbaueri, commonly known as Maushán or Mountain Papaya, is a rare papaya relative native to montane cloud forests in the Peruvian Andes. This species produces aromatic, sweet fruits used fresh, dried, or for liqueur production. Seeds exhibit physiological dormancy and require proper treatment and environmental conditions to achieve successful germination.
Before sowing
No pre-treatment needed — sow directly.
Gibberellic acid (GA3) treatment significantly enhances germination rates in Caricaceae family members. Drying seeds to reduced moisture content also improves germination potential.
Sowing
What to expect
Tips
Remove seeds from fresh fruit and clean thoroughly to eliminate inhibitory sarcotesta coating. Pre-treat with gibberellic acid or allow seeds to partially dry before sowing for improved results. Sow lightly covered seeds in sterile, moist substrate maintained at 22-26°C. Provide bright, indirect light; avoid direct sunlight initially. Maintain high humidity by keeping pot covered, but ventilate daily to prevent fungal issues. Germination is slow and irregular, occurring over 1-3 weeks. After emergence, gradually acclimate seedlings to open air and brighter conditions before transplanting to individual pots.
