巴西橡胶几乎是天然橡胶唯一的来源,随着世界对天然橡胶需求量的增长,以及为了使采胶更有利,必须提高产胶量,这在某种程度上取决于种植材料的同质性,目前橡胶种植材料的唯一繁殖方法(即嫁接法)仍存在变异性,这仅仅是因为缺乏无性繁殖的砧木所致。此外园艺上的插条试验表明,在生长期间插条的生根能力迅速减弱,而且长出的根系集中在地表层,因此通常植株不抗风。试管培养技术因能恢复幼态特性,应当可以解决这些问题。通过体细胞培养胚状体及试管培养微型插条的方法可以提供两种微型繁殖
Brazil rubber is almost the only source of natural rubber. As world demand for natural rubber increases, and in order to make it more profitable, it is necessary to increase the amount of glue that is produced, depending in part on the homogeneity of the planting material, At present, the only reproductive method of rubber planting material (grafting method) still exists variability, simply because of the lack of asexual reproduction of rootstock. In addition, horticultural cuttings showed that the rooting capacity of the cuttings rapidly diminished during growth and that the root system was concentrated on the surface so that the plants were generally not resistant to wind. Test tube culture techniques, because they can restore juvenile features, should solve these problems. The method of culturing embryos by somatic cell culture and micro-cuttings in vitro can provide two kinds of micropropagation
