Abstract: | Starch, lipids and proteins are localized histochemically in fusiform and ray initials ofTectona grandis andGmelina arborea during the periodicity of cambium in the year 1978. The histochemical variations are correlated with the seasonal activity and dormancy of the cambium and phenology. Starch grains appear in the cambial cells with the development of young leaves after defoliation. Lipid and protein bodies are significantly high in dormant cambial cells and scarce in active ones. |
