摘　　要：为了筛选适宜橡胶树小苗芽接小筒苗接穗生长的砧木大小。采用同一批次橡胶树裸根苗的不同砧木大小分为8个处理(0.5~1.2 cm)进行小筒苗培育。比较各处理对接穗第1蓬叶和第2蓬叶生长的影响。结果表明:砧木为0.5 cm的接穗长势最弱和出圃率最低,1.2 cm的接穗长势最好,0.9~1.2 cm的出圃率均达到85%以上。说明在砧木一定大小范围内橡胶树小苗芽接小筒苗,随着砧木的增大,长势越好;砧木足够大,出圃率没有受到砧木大小的影响。An attempt was made to select the most suitable size of rootstock for green buddings raised in the root-trainer container. The same batch of rubber bare-rooted budded stumps with different stem sizes of rootstocks were grouped into 8 different treatments（stem size from 0.5 to 1.2 cm） and raised in root-trainer containers to compare the effects of the treatments on the growth of the first and second whorls of the leaves of the scions. The results showed that the scion grew weak with the lowest transplanting rate when the rootstock stem size was 0.5 cm but the best when the rootstock stem size was1.2 cm with the transplanting rate of more than 85% when the rootstock stem size was from 0.9 cm to 1.2 cm. This showed that the buddings in the root-trainer containers grew better with the increase of rootstock stem size in a given range of stem size, and that the rootstock stem size had no effect on the transplanting rate of the buddings when the rootstock stem size was bigger enough.
