The production of a single stem, which is a characteristic of most members of the Arecaceae family, is a distinctive feature of the coconut palm (Cocos nucifera L.), oil palm (Elaeis guineensis Jacq.) and date palm (Phoenix dactylifera L.). This feature has been a constant for many palm species since the late Cretaceous period, but rare cases of shoot branching in coconut do occur. This original feature leads to multiple stem formation and is considered to be a novel trait. An understanding of the role of plant growth regulators in shoot branching offers a new pathway to produce multiple stem buds in a palm through in vitro culture. As the world's coconut crop is now facing a decline in productivity due to palm aging, extreme climate events, and biotic and abiotic stresses, this approach could help to meet the increasing demand for elite coconut seedlings. Hence, this review examines the potential for direct shoot organogenesis to be used as an option for the clonal propagation of coconut. Cytokinins are essential to induce direct shoot formation. Although more research is needed to confirm the best method to produce coconut clones, based on the literature, for direct shoot organogenesis, it is expected that a treatment of thidiazuron only (for embryo) or in combination with picloram (for immature inflorescence) in Eeuwens Y3 medium would produce the best likelihood of success. The feasibility of this pathway of plantlet production in coconut is bolstered by the relatively easy direct shoot organogenesis now available as an alternative clonal propagation protocol for oil palm and date palm.

单茎的生产是大多数槟榔科成员的特征，是椰子树 ( Cocos nucifera L.)、油棕 ( Elaeis guineensis Jacq.) 和枣椰树 ( Phoenix dactylifera L.) 的显着特征。 ）。自白垩纪晚期以来，这种特征对于许多棕榈树种来说一直是不变的，但椰子枝条分支的罕见情况确实发生了。这种原始特征导致多茎形成，被认为是一种新特性。了解植物生长调节剂在枝条分枝中的作用提供了一种通过体外在棕榈中产生多个茎芽的新途径文化。由于棕榈树老化、极端气候事件以及生物和非生物胁迫，世界椰子作物现在正面临生产力下降的问题，这种方法有助于满足对优质椰子幼苗日益增长的需求。因此，本综述考察了直接芽器官发生作为椰子克隆繁殖的一种选择的可能性。细胞分裂素对于诱导直接枝条形成是必不可少的。虽然需要更多的研究来确认根据文献生产椰子克隆的最佳方法，以用于直接芽器官发生，但预计在 Eeuwens 中仅使用噻二唑隆（用于胚胎）或与 picloram（用于未成熟的花序）联合处理Y3 培养基将产生最大的成功可能性。
