Apart from the high apical dominance showed in shoot explants of hevea, the location of the node in the shoot, seems to play a vital role in in vitro axillary bud proliferation. Better performance was observed when the axillary buds harvested as nodes, were not too close and also not too far from the apex as measured by the primary axillary shoot growth. This was true for both juvenile and mature arigin materials. Furthermore, "active" nodes were superior to "dormant" nodes.
