植物的无性繁殖方法在果树和其他园艺作物方面很久以前已进行,但是从植物的组织如腋芽、顶芽、或嫩枝的切片经组织培养而得的再生植物,则是近来才有的。从单一的分生组织的梢端生产几百个十分相似的兰花植物的可能性已被证实,这种叫组织培养的技术现在已成为商品性生产。 The vegetative propagation of plants has long been done in fruit trees and other horticultural crops, but recently regenerated plants have been obtained from the tissue culture of plant tissues such as axillary buds, terminal buds or shoots. The possibility of producing hundreds of very similar orchids from the tip of a single meristem has been demonstrated, and the technique called tissue culture is now commercialized.
