一、植物组织培养法在繁殖树木优良品种方面的作用植物组织培养法是用适当的培养基对植物细胞、组织、器官、胚等进行无菌离体培养的一种方法。这种方法最初应用对象和范围都比较窄。近40年来,随着近代分子生物学、细胞生物学、生理学、形态学和遗传学的发展以及某些先进技术的不断引进,植物组织培养技术发展迅速,应用范围也越来越广。它从最初对植物根的离体培养,发展
First, the role of plant tissue culture in the propagation of fine varieties of trees Plant tissue culture method is a suitable medium for plant cells, tissues, organs, embryos, etc. A method of sterile culture in vitro. The initial application of this method and the object is relatively narrow range. In recent 40 years, with the development of modern molecular biology, cell biology, physiology, morphology and genetics as well as the continuous introduction of some advanced technologies, plant tissue culture technology has developed rapidly and its scope of application is also becoming wider and wider. It grew from the initial culture of plant roots in vitro
