It is the factors affected plant regeneration in explant culture in Euphorbia pulchrrima willd to different explants or aurin or cytokinin or the combination of the auxin and cytokinin. 外植体的类型、植物生长素、细胞分裂素的类型及二者的不同组合均对一品红在离体条件下植株的再生具有影响。
Cytokinins (CK) are a class of plant growth substances (phytohormones) that promote cell division, or cytokinesis, in plant roots and shoots. They are involved primarily in cell growth and differentiation, but also affect apical dominance, axillary bud growth, and leaf senescence. Folke Skoog discovered their effects using coconut milk in the 1940s at the University of Wisconsin–Madison.
