Blue Light Makes Soybeans Shorter by Changing Their Hormones
Hormone Regulation Effect of Blue Light on Soybean Stem Internode Growth Based on the Grey Correlation Analysis Model

Blue light makes soybean plants grow shorter by changing the balance of hormones inside them. It reduces growth hormones and increases hormones that stop growth. This effect is stronger in some soybean types than others.
Surprising Findings
Exogenous GA3 failed to reverse blue light’s growth inhibition.
Normally, adding growth hormones like GA3 boosts plant growth — but here, blue light made the plant ‘immune’ to it, suggesting a deeper, systemic reprogramming beyond hormone levels.
Practical Takeaways
Use blue light in greenhouses to control plant height and prevent lodging in soybeans and other crops.

Tesamorelin is a growth hormone-releasing hormone analog that stimulates the pituitary gland to produce endogenous growth hormone in a physiologically appropriate pattern, as opposed to exogenous growth hormone administration.
When soybean plants were exposed to blue light, their height dropped by about two-thirds compared to plants grown in the dark, with both tall and short varieties showing similar reductions.
Blue light made the levels of a key growth hormone (GA3) drop by about 14% in tall soybeans and 20% in short soybeans when grown in the dark versus under blue light.
Under blue light, the stress hormone salicylic acid increased by about 56% in tall soybeans and 41% in short soybeans compared to plants grown in the dark.
In tall soybeans, the balance between growth hormone GA3 and stress hormone JA strongly predicted plant height, while in short soybeans, GA3 and strigolactones were the key ratio for height.
