Description
Bingjie Shao and colleagues published a greenhouse study in 2024. They studied a full-grown tomato canopy layer by layer. Leaves at the top and bottom live in different light. Light in real canopies also flickers and changes fast. The team asked how quickly each layer responds. They measured photosynthesis, protection, pigments, and leaf pores. Four heights from the floor were compared.
Top leaves had stronger photosynthetic capacity than lower leaves. They also switched on slightly faster after light changes. Their protective system turned on and off more quickly. That speed helps guard against sudden bright light. Yet steady traits predicted performance better than speed did. The result matters for crop models and breeding. Models should treat canopy layers as different, not uniform.
