Genotype-specific response of cultured broccoli (Brassica oleracea var. italica) anthers to cytokinins

摘要: Anther culture medium was prepared with different types and concentrations of cytokinins to gain greater insight into the control embryo formation during Brassica oleracea L. var. italica (broccoli) anther culture. The independent addition four tested had widely divergent effects dependent upon cytokinin concentration genetic background test plants. All were generally inhibitory at high concentrations, however, individual plants showed significant stimulation embyro typical physiological levels. influence highly cultivar-specific, some lines stimulated, others inhibited still other largely unaffected. Although needed for plants, in no instance able replace inductive effect high-temperature treatments.
