橡胶树是异花授粉植物,实生树的橡胶产量株问差异甚大,平均产量不到芽接树的1/3。目前,生产上大部分种植芽接树(但砧木对接穗的影响达15%-40%),只有少部分缺乏种胶知识的胶农种植实生树。为了获得更高的橡胶产量,培育高产无性系的扦插苗成了各国橡胶树栽培育种研究者的共同课题 Rubber tree is cross-pollinated plants, tree production of rubber trees vary greatly, the average yield less than bud tree 1/3. At present, most of the buds are planted in the production (but the impact of the rootstock on the scion is 15% -40%). Only a small part of the growers who lack the knowledge of plasticizing seedlings are planted with live trees. In order to obtain higher rubber yields, the cultivation of cutting clones of high-yielding clones has become a common topic for researchers in rubber tree cultivation and breeding in various countries
