SUMMARY A quantitative study is made of the changes in the soluble sugar content of developing cocoa leaves. Fructose, glucose, inositol and sucrose were the major sugars present. The possibility that endogenous sucrose concentration can affect chloroplast development is considered. Estimates of the net daily sucrose synthesis in a developing cocoa leaf are made from photo‐synthetic and respiration rate measurements, and it is shown that the leaf does not become self‐dependent for respiratory substrate until after the termination of leaf expansion.
