橡胶树混合芽（即橡胶树“花芽”）发育不同阶段的形态结构观察及秋水仙素对其染色体数诱导加倍的研究结果表明：长１．５－３．９ｍｍ的萌动混合芽处于圆锥花序的分化初期，其生长锥下方刚形成花序的一级分枝原基，细胞分裂量较大，在该阶段用０．２５％秋水仙素溶液进行染色体数加倍处理，较易获得整体加倍的变异花序。
Morphological observation of the different stages of rubber tree hybrid buds (ie, rubber tree “flower bud ”) development and double induction of colchicine on its chromosome number showed that the buds with 1.5-3.9 mm in length were in the panicle In the early stage of differentiation, a primary branch of inflorescence formed just below its growth cone, with a large amount of cell division. Chromosome number doubling treatment with 0.25% colchicine solution at this stage made it easier to obtain an overall doubling variation of inflorescence .
