植物组织培养最早是植物生理研究中采用的一种方法.它指的是植物体部分组织在培养基中的无菌培养.在培养过程中,其组织可以维持新陈代谢机能,其细胞能够继续进行分裂繁殖.培养不同部位的组织,或采用不同的培养条件,是为了达到不同的研究目的.因此,组织培养本身并不是一个分支学科,而是一项很有价值的实验技术. 近年来,植物组织培养技术的应用范围愈来愈广,从植物生理学到遗传、育种直至分子植物学等各个领域均有应用.取材范围也不仅限于组织了,小可到花粉、单细胞、原生质体以至细胞器,大可到整个器官如花药、子房、芽、叶片甚至茎段.于是,组织培养本身的概念也更广泛了,人们往往把上述材料的培养笼统地都称作组织培养.
Plant tissue culture is one of the first methods used in plant physiology research, which refers to the aseptic culture of plant tissue in culture medium, which can maintain the metabolic function of the tissue during its cultivation and its cells can continue to divide Breeding different parts of the organization, or using different culture conditions, in order to achieve different research purposes.Therefore, tissue culture itself is not a branch of discipline, but a very valuable experimental technology.In recent years, plant tissue The range of application of cultivation technology is getting wider and wider, ranging from plant physiology to genetics, breeding to molecular botany, etc. The scope of application is not limited to tissues, small to pollen, single cell, protoplast, organelle, large The whole organ, such as anthers, ovaries, buds, leaves or even stem segments, can be reached. Thus, the concept of tissue culture itself has become more widespread, and the cultivation of these materials is often referred to as tissue culture.
