Aim. To study the influence of antibiotics Ceftriaxone and Timentin on the morphogenic calli and roots formation, shoots regeneration in two bread wheat cultivars Triticum aestivum L., to study effect of Ceftriaxone on the growth dynamics of plants. Methods. In vitro plant tissue culture, analysis of Variance, correlation and regression analysis. Results. The influence of β-lactam antibiotics Ceftriaxone and Timentin on morphogenetic processes (morphogenic calli formation, shoots regeneration and rhizogenesis), was studied in apical 18-day-old wheat calli. Two wheat genotypes of different growth habits, winter and winter-spring, were used. Conclusions. Timentin and Ceftriaxone stimulate morphogenic calli formation in bread wheat apical calli. As compared to Timentin, Ceftriaxone has strong concentration-dependent and genotype-dependent influence on shoots regeneration. The roots formation depended primarily on the wheat genotype, independently from an antibiotic applied. The presence of Ceftriaxone in culture medium stimulates rooting and growth of regenerating plants as well as their biomass increment.
Aim. To find out, at which concentration the antibiotic ceftriaxone of β-lactam group causes the elimination of ABI and GV3101 strains of Agrobacterium tumefaciens. Methods. The disc diffusion method. Results. Antibiotic ceftriaxone was used for the cell elimination of the Agrobacterium tumefaciens ABI strain for the first time. The same zones of inhibition were observed when using the 400 mg/l ceftriaxone and 500 mg/l cefotaxime solutions for both Agrobacterium strains (ABI and GV3101) studied. Conclusions. Ceftriaxone inhibits the Agrobacterium growth more effectively than cefotaxime. The ceftriaxone concentration for elimination of ABI and GV3101 Agrobacterium tumefaciens strains is 400 mg/l.
