→Vegetative growth
Most rattans growing naturally produce abundant seedlings, but high mortality, presumably through competition for light, water and nutrients, and through predation, leads to only a few seedlings attaining maturity. For high climbing rattans, earlier stem production from the rosette stage and greater production of stems in a clump are initiated by exposure to adequate light; light also enhances stem elongation (Manokaran, 1985). Stem elongation is continuous but variable from period to period.
Whereas there is no published information on the growth rates of rattans growing in the wild, such information is available for commercial species undergoing silvicultural trailstrials. Some information is provided in Table 4.
