FP23091Blue light regulated lignin and cellulose content of soybean petioles and stems under low light intensity
Increasing plant density is an important way to improve soybean yields, but risks increased lodging. Light plays a crucial role in regulating structural polymers that provide mechanical support to plants. Under a low light intensity, blue light regulated lignin and cellulose content of soybean petioles and stems. Under low light intensity, 20% blue light enhanced petiole length and lignin content; whereas 50% blue light increased cellulose content in stems and lowered plants’ centre of gravity, preventing lodging and saving carbohydrate allocation.
