Screening of cytokinins in induction of shoot organogenesis on tobacco and petunia Ieaf segments

Popis výsledku v původním jazyce

The presence of cytokinins in the culture medium and their active form in explants is an important factor for induction of shoot organogenesis (Christianson and Warnick 1984). Isopentenyladenine (iP) and 6-benzylaminopurine (BAP) are the most frequentlyused cytokinins for in vitro differentiation of buds (Gaspar et al., 1996). Recently aromatic cytokinins -benzylaminopurine and their derivatives have been used for the study of physiological activity in morphogenesis (Werbrouck et al., 1996). The levelof cytokinins and multiple shoot formation on leaf segment of tobacco and petunia was studied using an addition of BAP (6-benzylarninopurine) or iP (isopentenyladenine) and/or mTR (meta-topolin riboside). The aim of this study was to compare the cytokinin activity in morphogenesis. Tobacco and petunia segments from the middle part of the leaves were cultivated on induction medium with a high concentration of cytokinin (1.5 mg.r1) and low concentration of l-naphtalene acetic acid (0.18 mg
