Photosynthesis and productivity

Abstract

This chapter on photosynthesis and productivity in litchi (Litchi chinensis) and longan covers the following: relationship between photosynthesis and plant development; effects of the environment on photosynthesis; assimilate production and distribution; relationship between fruit growth and leaf expansion; relationship between yield and assimilate supply; relationship between fruit size and yield; relationship between yield and tree size; effects of light and temperature on growth and productivity; effects of planting density and pruning on productivity; and practical aspects of pruning. Tabulated data on the productivity of litchi and longan in China and Thailand, and on the effects of leaf position and stage of development on leaf fresh weight and area, chlorophyll content, net carbon dioxide assimilation, and stomatal conductance in litchi (cv. Bengal) in Queensland, Australia, are presented.
