Production of natural rubber is a kind of bio-industry which needs large scale plantation, a huge sum of money and assets/The more latex be produced from natural rubber plants with high polyisoprene content, the more advancement of production are needed to improve the cost-performance financially. Then, in order to improve the production of plantation, the process of selection breeding and cultivation has been continuing for over 150 years. Since the natural rubber industry depends on the bioresource of plants, the improvement of production will be an industrial theme forever.

Natural rubber tree has a special organ named lactiferous cell which synthesizes and accumulates hydrophobic compound.This report gained a bio imagine of lactiferous cell of two kinds of natural rubber plants by using articulate lactiferous cell localized in Para rubber trees (Hevea brasiliensis Muell. Arg.) of cis-polyisoprene and phloem localized as crystallized polymer in Hardy rubber trees (Eucommia ulmoides Oliver) of trans-polyisoprene. From this result, we introduce the sink and source relationship needed to improve the natural rubber plants production and research the morphological characters of lactiferous cell which stores polyisoprene, a kind of unproductive compound to plants.
