Aim. To perform an analysis of the effectiveness of our proposed modification of the classical MS medium in which auxin and cytokinin are replaced by derivatives of the class of tetrahydrothio-fendioxide and pyridine. Methods. In this study, the work with cell culture in vitro, in particular aseptic sprouting of seeds, microclonal reproduction, callusogenesis and initiation of various types of morphogenesis was carried out according to known techniques. Two varieties of potatoes (Slovyanka, Lugovskaya) and two varieties of tomato (Lagidny, Bobrytsky) were used to induce somaclonal variability. Results. The ability of preparations of tetrahydrothiophenedioxide and pyridine derivatives to perform the function of auxins and cytokinins in the MS medium in the callusogenesis of Solanacea cultures in vitro was established. Conclusions. It has been shown that with the use of the new generation drug (tetrahydrothiophenedioxide-pyridine), as a substitute for auxin and cytokinin in the MS medium, the growth of callus tissue is even increased. The production of the pilot batch of this substitute proved to be much cheaper than synthesis or the purchase of phytohormones. Keywords: modification of MS medium, phytohormones substitute, tetrahydro-thiophenedioxide-pyridine, potato, tomato.

A protocol was developed to produce large amount of callus in short a period of time from leaf explants of Stevia rebaudiana Bert. The highest amount of white callus was obtained on MS medium supplemented with 2.5 mg/l 2, 4-D and 0.5 mg/l BAP after 3 weeks of inoculating leaf segments. On the other hand, 0.5 mg/l BAP and 1.0 mg/l Kn exhibits poor performance towards callus formation while after using 1.0 mg/l Kn alone did not develop any callus. In this experiment, highest amount of green callus was obtained when MS medium supplemented with 2.5 mg/l NAA and 10% coconut water was used. An improved analytical method HPLC was applied to analyze stevioside extracted from the leaf and callus of Stevia rebaudiana. The stevioside in each sample were analyzed by comparing their retention times with those of the standards. The retention time (RT) of stevioside for leaves were found 14.96 and for callus 13.81 mins. The percentage of stevioside content from leaves and callus was 12.19% and 12.62% respectively DOI: http://dx.doi.org/10.3329/bjsir.v49i4.22621 Bangladesh J. Sci. Ind. Res. 49(4), 199-204, 2014

Previous studies showed that derivatives of pyrazinecarboxylic acid used as elicitors increased either flavonoid or flavonolignan production. The effect of 2-(3-bromobenzylsulfanyl) pyridine-4-carbothioamide on isoflavonoids production in Genista tinctoria culture in vitro was tested. The highest isoflavonoid content (0.3 mg.g−1 DW) in callus culture was found after elicitor application at a concentration of 2.96 × 10−5 mol.L−1 after 24 h of treatment. The maximum daidzein production (0.2 mg.g−1 DW) was detected after 48 h of elicitor treatment at a concentration of 2.96 × 10−3 mol.L-1 and after 24 h of elicitor treatment at a concentration of 2.96 × 10−5 mol.L−1. Suspension culture produced the highest amount of isoflavonoids (0.3 mg.g−1 DW) after elicitor application at concentrations of 2.96 × 10−4 mol.L−1 after 24 and 168 h of treatment, and 2.96 × 10−5 mol.L−1 after 168 h of treatment. The highest content of genistin (0.3 mg. g−1 DW) was detected after 24 h of elicitor treatment at a concentration of 2.96 × 10−4 mol.L−1. The maximum content of daidzein (3.80 mg.L−1) released into the suspension culture medium was found after elicitor application at a concentration of 2.96 × 10−4 mol.L−1 after 12 h of treatment.
