Zimmerman & Bromme and Schenk & Hildebrandt media with unchanged content of plant growth regulators in the basic medium, were used to develop the optimum conditions for efficient production of callus tissue of Vaccinium corymbosum var. Bluecrop. It has been determined that, of the auxins used, it was 2,4-D which has the most beneficial effect on callus tissue growth. Zeatin was found to regulate the water content of the tissue obtained. Quercetin-3-O-glucoside, as well as quercetin-3-O-galactoside were identified and analysed quantitatively in the callus tissue from in vitro cultures. Moreover, the following phenolic acids were identified in the callus with the use of chromatography: ferulic acid, p-hydroxybenzoic acid, p-coumaric acid, as well as gallic acid and protocatechuic acid which were also analysed quantitatively in the researched tissue material. Phytochemical monitoring of the propagated tissues for different production media (HPLC analysis) did not show any relationship between the plant growth regulators used and the analysed secondary metabolites.
