象牙海岸的胶园全部是用无性系作种植材料的。接穗取自推荐的经选优良无性系。用知母本的种子繁殖砧木材料。与接穗的情况相反,砧木材料的异质性很大,因为极少是经过选择的。很久以来,已经不断有人指出,砧木可能对无性系的生势和产量有影响。此点已为在象牙海岸进行的,FAGT1、PB86和PR107作试验材料的研究结果所证实。因此,推荐种植材料时必须同时考虑接穗和砧木两方
The rubber plantations in Ivory Coast all use clones for planting material. Scion taken from the recommended by the selected excellent clones. The mother plant seed germination stock material. In contrast to the case of scions, rootstock materials are heterogeneous because few are selected. It has long been pointed out that rootstocks may have an impact on clonal upset and yield. This is evidenced by the findings of the FAGT1, PB86 and PR107 materials tested in Ivory Coast. Therefore, when planting material is recommended, both scion and rootstock must be considered
