Authors


Summary

Quantitative analyses for total methanol-soluble material, methanol-soluble carbohydrates, anthocyanin, chlorophyll, methanol-insoluble nitrogen, saponifiable material, pectin, lignin, hemicellulose, and α-cellulose were made at weekly intervals for the first 6 weeks of the growth of mango leaves. The results show that in the first 4 weeks, when the leaves contain anthocyanin, production of photosynthetic carbohydrates was low, and lignin and cuticle syntheses -were virtually absent. The increase in rigidity of the mango leaf between the second and fifth weeks was significantly correlated with an increase in the hemicellulose content of the leaf.
