Momordica cochinchinensis, commonly known as gac or baby jackfruit, is a dioecious perennial climbing vine native to Southeast Asia. The fruit is rich in carotenoids, particularly beta-carotene and lycopene, making it valued in traditional cuisine and medicine. Germination is moderately straightforward when proper warm, humid conditions are provided, though seeds have physical dormancy that benefits from pre-treatment.
Before sowing
Seed soaking in warm water for 24 hours is recommended. Seed coat removal or scarification may improve germination, particularly for older seeds
Sowing
What to expect
Tips
Maintain soil temperature between 25-30°C using a heat mat for optimal germination; provide warmth, air circulation, and bright light during germination. Place seeds with the small hole/opening facing downward into the soil. Seeds will germinate in 7-14 days under proper conditions. Keep substrate consistently moist but not waterlogged. Use fresh seeds when possible, as germination capacity decreases with storage time. After germination, transplant seedlings to larger containers 2-3 weeks later. Note: Gac is dioecious (separate male and female plants), so multiple plants are needed for fruit production. Start seeds 8 weeks before intended transplanting.
