Accompanied by oxidative stress as a signal to activate defense mechanisms, various abiotic factors induce
peroxidation of membrane lipids. The aim of this research was to analyse changes in lipid peroxidation
(LP) intensity and antioxidant capacity of selected sugar beet genotypes during micropropagation under the
conditions of water deficit. Performed research represents a part of a more comprehensive study, the purpose
of which is understanding the difference in acclimation to drought as the major abiotic factor limiting sugar
beet production in Serbia. The best solution for overcoming this obstacle in successful sugar beet growing is
breeding for drought tolerance. Tested sugar beet genotypes were grown and multiplied in vitro on standard
nutrient medium. Axillary shoots were placed on the micropropagation media with 3% and 5% PEG for 28
days, which caused physiological drought stress. All genotypes could be divided into three groups according
to the level of LP, however o...nly two of eight genotypes had significantly higher LP intensity during drought
conditions when compared to their controls (10.1-29.1%), as well as significantly reduced antioxidant activity
(22.2-59.9%). A slight decrease in LP intensity and enhanced antioxidant capacity (up to 92.9%) in comparison
to control were recorded in treatments of the rest of investigated genotypes. As for correlation between
tested biochemical parameters and growth conditions, all genotypes differed in their response to PEG concentration.
Obtained results showed that LP intensity and antioxidant capacity could be used as biochemical
parameters in assessing drought tolerance of individual genotypes in further selection of sugar beet.
