摘要

What controls plant growth? Although, photosynthesis is essential for plant growth, photosynthetic carbon acquistion rarely controls the rate of growth. Tissue formation (structural growth) is rather directly and more strongly controlled by the availability of water and nutrients as well as by temperature, so that the rate of tissue formation controls the amount of photoassimilates that can be invested in growth (and is produced in the first place).
