Boswellia serrata, commonly known as Indian frankincense, is a medium to large deciduous tree native to India and Pakistan that produces valuable gum resin used in traditional Ayurvedic medicine and aromatherapy. The species is endangered and shows poor natural seed germination due to high proportions of empty seeds and low viability, though freshly collected seeds can reach 73% germination. This species requires careful seed selection and specific germination conditions, making it moderately difficult to propagate from seed.
Before sowing
Pre-treatment is recommended but not strictly required. Soaking is the primary recommended pre-treatment. Gibberellic acid (GA3) at 750 ppm for 36 hours can significantly improve germination rates to 88% after 30 days.
Sowing
What to expect
Tips
Seeds have variable viability and may contain up to 90% empty seeds lacking viable embryos. Perform a float test by soaking seeds in water for 7 hours to identify and remove sterile pyrenes and empty seeds before sowing. Highly sensitive to excess moisture and fungal pathogens; ensure excellent drainage and air circulation to prevent damping-off. Water sparingly and allow soil surface to dry slightly between waterings. Keep soil consistently moist but not waterlogged during germination. Place in a warm, bright location with indirect sunlight. Germination can be slow (7-28 days) and sporadic. Transplant seedlings once they have several true leaves and are stable. Boswellia serrata is adapted to arid, dry environments and performs best in fast-draining, well-aerated soils. Seeds have short dormancy and should be used fresh; viability drops significantly after 6-9 months of storage.
