Some Aspects of the Growth of Mango (Mangifera Indica L) Leaves

S ummary 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.
