Conservation Propagation
PubMedRare aquatic plants like this one quietly anchor the ecosystems of ponds and wetlands you might visit — and having a proven lab method to rescue them from extinction means those habitats have a fighting chance even as wild populations disappear.
Researchers figured out the exact recipe of plant growth hormones needed to take a small cutting of this endangered water plant and coax it into growing roots, shoots, and eventually a full healthy plant — entirely in a lab dish. The plant had never been successfully grown this way before, making it nearly impossible to save if its wild populations vanished. Now scientists can produce thousands of copies of it to replant in the wild or study for future uses.
Key Findings
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.
chevron_right Technical Summary
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.

Hydrocera is a genus of flowering plants in the family Balsaminaceae (balsams). It contains a single species, Hydrocera triflora, from Southeast Asia. It is the only other genus in the family Balsaminaceae besides Impatiens.
