Abstract
The significance of cultivar colour (orange and yellow), the application of MgO during field cultivation and chosen phytohormones in the callus cultivation medium are investigated in the present study, with respect to the antioxidative properties of the obtained callus. Callus cultivation are examined as an alternative method for the production of plant antioxidant compounds. Cultivar choice was most significant for callus production and the synthesis of health-promoting metabolites. The best combination, with respect to the induction efficacy and antioxidant properties measured as a synthetic value by Multidimensional Comparative Analysis (MCA), was found in the callus of cultivar ‘Flacoro’, cultivated without MgO fertilization and on a medium with kinetin (KIN) and 1-naphthaleneacetic acid (NAA) (MCA-value 0.465). The worst performance was found for cultivar ‘Yello Mello’, independent of the applied phythormones (averaged MCA-value 0.839) and for the cultivar ‘Flacoro’ fertilized with MgO and independent of growth hormones (averaged MCA-value 0.810).
Highlights
Many higher plants are major sources of useful secondary metabolites that are used in the pharmaceutical and agrochemical industries
The extraction of secondary metabolites from in vitro tissues is much simpler than obtaining them from complex plant tissues [1]
The attempt to increase the content of biologically active compounds in carrot roots by in vitro techniques is associated with difficulties in maintaining appropriate procedures and obtaining reproducible results for each cultivar
Summary
Many higher plants are major sources of useful secondary metabolites that are used in the pharmaceutical and agrochemical industries. Biotechnological methods and in particular plant tissue culture, play an important role in the search for alternative forms of production of desirable compounds of medicinal nature [2,3,4,5]. Plant cell cultures produced ingredients for flavourings, aromas, fragrances, biofuels, plastics, enzymes, preservatives, cosmetics, natural colours and bioactive compounds [2,3,4]. Secondary products in plant cell culture can be produced without environmental restrictions during the entire year with less seasonal limitations. Production under these conditions is robust, predictable and independent of weather conditions. The extraction of secondary metabolites from in vitro tissues is much simpler than obtaining them from complex plant tissues [1]
