茎是植物的重要组成部分,并具有支撑和运输功能,为了诱导茎成为能够发育再生植株的分生组织与胚性细胞,我们可以采用离体培养的方法,将分割后的茎切块放在具有不同生长素和细胞激动素的培养基上,并通过营养因素和培养条件对形态发生过程的趋势加以控制。茎离体培养的研究早在十九世纪初就已开始。到目前为止,茎的离体培养大体可以 Stems are an important part of plants and have the function of support and transport. In order to induce shoots to become meristematic and embryogenic cells capable of developing regenerative plants, we can use the method of in vitro culture, With different auxin and cytokinin medium, and through the nutritional factors and culture conditions on the morphological process of the trend to be controlled. Studies of stem in vitro culture began as early as the early nineteenth century. So far, in vitro culture of stems has generally been possible
