Histochemical methods are highly useful to understand and locate the various metabolites in the plant tissue system like secondary phloem, bark, of Hevea. Phloem serves as the pathway for the transport substances synthesised by photosynthesis and also may provide as a system for storage molecules like starch, lipids, proteins, phenolic substances, tannins etc. In Hevea brasiliensis, bark has another important role, in which laticifers are distributed in the form of concentric rows and wounded by the process of tapping to extract latex. Considering the role of starch as a major metabolite in plants, it is significant to understand the occurrence and distribution of it in the bark tissue of H. brasiliensis. Samples from 10 clones of H. brasiliensis were taken in the present investigation and bark tissues were stained with Iodine-potassium iodide for starch deposition. Soft bark region contiguous to cambium had low level of starch, but the inner and outer hard bark had copious amount of starch occurrence. Among the parenchymatous tissue systems, axial parenchyma cells had recorded intense amount of starch grains compared to ray parenchyma cells. Starch grains were somewhat oval in shape and in many cells they were grouped. The present findings throw light into distribution and pattern of starch grains in H. brasiliensis.
