胚培养系克服植物种胚不育或加速繁殖进行胚的人工离体培养技术。一般用种子繁殖的植物(包括野生植物在内),种胚不育的问题是不存在的。但是,当它们进化为栽培植物时,由于果实的成熟期是人类非常注意的重要经济性状,获得后为保持其优良特性,便用无性繁殖法繁殖,久而久之,胚的发育速度,对品种保存却变得无关紧要了。这就造成了一些早熟种的胚,在母体组织内不能正常发育的后果。这种现象在核果类果树中是经常可见的。此外,在 Embryo culture line to overcome the plant embryo sterile or accelerated propagation embryo artificial in vitro culture technology. The general breeding of plants with seeds (including wild plants, including), the problem of sterile embryos does not exist. However, as they evolve into cultivated plants, since the fruit ripening period is an important economic trait that human beings pay great attention to, they are multiplied by asexual reproduction method after being acquired. In the course of time, the development speed of the embryo, It becomes irrelevant. This has resulted in the consequences of the failure of some precocious embryos to develop normally in maternal tissues. This phenomenon is often seen in stone fruit trees. In addition,
