ABSTRACT: Photosynthesis, the most important
physiological process in plants, can produce not only ATP and NADPH used in
other processes but also carbohydrate, the key factor for crop yield.
Production of photoassimilates is often influenced by various environmental
factors such as light, temperature, CO2, water, mineral elements and
leaf stage and position. Here we focused on the light-mediated regulation of photoassimilate
translocation in plants and the application of light environment control in greenhouse
production. We also reviewed the effects of other factors including leaf age
and position, air temperature, CO2 concentration and water and
mineral element supply on photoassimilate translocation in plants. Finally some
perspectives have been proposed.
