橡胶芽接树是由地面上的接穗与地面下的砧木两部分组成。在更新计划中,作为接穗的无性系是经仔细选择的。然而人们却不大注意选择砧木。通常认为砧木类型是不重要的,而只要求其大小可进行芽接即可。之所以如此并非缺乏这方面的试验资料,而是由于没有很好地强调砧木的作用,对使用优良砧木的好处也未阐述清楚。再则,至今推荐使用的优良砧木也不多。以往的调查证明了砧木对接穗的生长和产量都有影响。一些研究也表明砧木对 Rubber budding tree is the scion on the ground and ground under the rootstock two parts. In the update plan, clones as scions are carefully chosen. However, people do not pay attention to choose rootstocks. It is generally considered that rootstock type is unimportant and that budding is only required for its size. The reason why this is not the lack of experimental data in this area, but because the role of rootstocks is not well emphasized, the benefits of using good rootstocks are not clearly defined. In addition, there are not many good rootstocks recommended so far. Previous surveys have shown that rootstocks have an impact on the growth and yield of the scion. Some studies also show that rootstock pairs
