摘要：Coir pith, a by-product of industry, renewable sourceis dark brown in color, fibrous in condition. Thephysical properties and anatomical studies of various ages of coir pith were done to determine the efficiency offormation of primary and secondary cell wall in fresh and old coir pith.The cell wall structure, lignin composition andthe anatomical view in the collected coir pith were examined through light microscopy and TEM analysis. It wasobserved that the cell wall structure of the old coir pith of about 5 years old did not support the structure, which showedpoor structure whereas the fresh coir pith of 7 days old had improved cell wall structure identifying both the primaryand secondary cell wall. From light microscopy, it was observed that the old coir pith possessed less lignin compositionthan the fresh coir pith. The fibrils and the cuticle were clear in the fresh coir pith unlike old coir pith. This proved theefficiency of fresh coir pith to be used as a raw material. It was observed that the structure identification in the coir pithis directly proportional to time which tends to lose its structure as it degrades.
