Rubber Plant: Aspects of Biology for yield Production

The outermost bark layers of rubber trees are methodically removed to collect latex. The interior soft zone (nearer to the cambium) and the external hard zone are two separate layers that make up the anatomical organization of the bark structure of Hevea, According to Gomez (1981) and MRB (2005) (stone cells and cork). Laticifers are successively formed in the cambium region of Hevea, where they develop mostly in the soft bark layer where latex is created. The bark surface and various laticifers in Hevea species were, however, poorly described in earlier research by rubber plant breeders (Frey-Wyssling, 1930, RRIM, 1957; RRIM, 1963, RRIM, 1994). According to theories, the laticifers’ roles include latex manufacturing, physiological functions, cellulose content creation, insect defense, and participation in a transportation pathway (Pakianathan et al., 1989; Kutchan, 2005; Pickard, 2008; Konno, 2011). The rubber tree’s laticifers are described by Esau (1965) and Shamsul Bahri (2000) as a collection of articulated fused cells that support latex and form systems that infiltrate the body of the plant via numerous tissues. Other plant species, such as the papaver and Lactuca (lettuce) species, are part of similar laticifer systems. However, non-articulated laticifers, which are laticifers that are not fused, are created from individual cells and grow into branching or unbranched tube-like structures (de Fay and Jacob, 1989; Shamsul Bahri, 2000; Hagel et al., 2008).
