通过离体培养,从植物的细胞、组织或器官再生完整植株的植物种类已达几百种之多,但是能够把离体培养技术用于商品化生产的植物种类却为数有限,究其原因,主要困难之一是由于一些植物的无根苗难以生根或从瓶中移栽出来后难以成活。为解决这一关键性问题,从事植物离体培养研究的大多数研究者,几乎毫无例外地都进行了诱导生根和改进移栽方法的研究。Paul、M.Hase- There are hundreds of plant species that have been regenerated from plant cells, tissues or organs by ex vivo culture, but there are only a limited number of plant species that can be used for commercial production in vitro. The reason, One of the main difficulties is the inability to survive because rootless seedlings of some plants are difficult to root or transplanted from the bottle. To address this crucial issue, most researchers engaged in plant in vitro studies have almost without exception conducted studies that induce rooting and improve transplanting methods. Paul, M. Hase-
