由于营养繁殖,花器官的颜色、大小和形状方面的突变容易识别,所以大多数这类作物可以进行诱发突变。所谓“不定芽技术”,已成功地用于某些花卉的突变育种。这种技术是以离体叶柄上不定芽的顶端细胞主要起源于单一(表层)细胞这一现象为依据的,经辐射诱发突变继而在离体叶上形成不定芽后,就产生了正常(未突变)植株和花色几乎一致(非嵌 Most crops of this type can induce mutations due to their ability to recognize mutations in the color, size and shape of floral organs due to vegetative propagation. The so-called “adventitious bud technology” has been successfully used for the mutation breeding of some flowers. This technique is based on the phenomenon that the apical cells of adventitious buds on isolated petioles originate mainly from a single (superficial) cell. After irradiation-induced mutation followed by adventitious bud formation on detached leaves, normal Mutation) Plant and flower color is almost the same (non-embedded
