Název v původním jazyce

In vitro shoot organogenesis and comparative analysis of endogenous phytohormones in kohlrabi (Brassica oleracea var. gongylodes): effects of genotype, explant type and applied cytokinins

Popis výsledku v původním jazyce

Kohlrabi (Brassica oleracea var. gongylodes) cultivars Vienna Purple (VP) and Vienna White (VW) were tested for their ability of de novo organogenesis in vitro. Root, cotyledon, hypocotyl explants and intact seedlings were cultivated on Murashige and Skoog (MS) media supplemented with different cytokinins: benzyladenine (BA), thidiazuron (TDZ), trans- or cis-zeatin. All tested cytokinins, including cis-zeatin, induced shoot regeneration from hypocotyl explants and intact seedlings, with seedlings beingmost successful for regeneration efficiency and viability of regenerated shoots in both cultivars. The highest frequency of shoot regeneration was achieved on MS with BA (60 %) or TDZ (50 %) for VP; and with BA (50 %), TDZ (47.5 %) or transZ (37.5 %) forVW. Measurements of the endogenous cytokinin and indole-3-acetic acid (IAA) contents in both hypocotyl explants and seedlings with regenerated shoots (HRSs and SRSs) suggested that the observed differences in organogenic response between
