دانلود Regulation of Photoassimilate Distribution between Source and Sink Organs of Crops through Light Environment Control in Greenhouses

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.
