Scientists Just Discovered Light Can Actually Slow Plant Growth

Researchers found that white light strengthens adhesion between pea stem tissues through a buildup of p-coumaric acid.

The added tissue cohesion makes the stem more rigid and slows expansion growth.

The study from Osaka Metropolitan University, published in Physiologia Plantarum, reveals a new way light shapes plant development.

The findings could help scientists better understand crop growth control and improve resilience.
