ex-situ-conservation
Ex situ conservation is the practice of preserving plant species outside their natural habitats — in botanical gardens, seed banks, or tissue culture facilities — to protect them from extinction when their wild environments are threatened. This approach is critical for plant science because it safeguards genetic diversity that would otherwise be lost, while also providing living material for research into plant biology, breeding, and restoration. It serves as a vital safety net alongside in situ efforts, enabling scientists to study and potentially reintroduce rare or endangered species to the wild.

Scientists have created the first lab-based method to grow and multiply Hydrocera triflora, a rare aquatic plant found in Southeast Asia that is at risk of extinction. By carefully balancing plant hormones, they achieved near-perfect shoot and root growth, opening the door to large-scale conservation efforts.
Shoot induction reached 96% success using 1.0 mg/L BAP and 0.2 mg/L IBA, producing 3–12 new shoots per cutting.
100% of plantlets successfully developed roots on standard MS medium with 0.2 mg/L IBA, averaging 16.1 roots and 6.3 cm root length per plant.
This is the first ever complete lab propagation protocol established for Hydrocera triflora, a phylogenetically significant endangered aquatic species.
