CO2 exchange, variable chlorophyll fluorescence, the intensity of lipid peroxidation (POL), and the activity of antioxidant enzymes in leaves of two-week-old pea seedlings (Pisum sativum L.) exposed to 0.01, 0.1, and 1 mM aqueous solutions of Cd(NO3)2 for 2 h were studied. Incubation with Cd2+ ions resulted in a reduction of the maximum quantum efficiency(More)
The adaptive reactions of Vicia faba major L. cv. Bartom to 13-27 days soil flooding and to 14 days of drainage following 13-days of soil flooding were studied. Under flooding, oxygen diffusion rate (ODR) in the root zone decreased from 2.28–3.44 to 0.09–0.28 µmol O2 m−2 s−1; the soil redox potential (Eh) decreased from 543 to 70 mV. Upon drainage of(More)
The extent of damage caused to the photosynthetic machinery of 10-d-old wheat seedlings by short-term exposure to mild heat, their capacity to recover from it and the possible roles of H2O2, SOD, catalase and ascorbate peroxidase on the recovery process were investigated. Seedlings were subjected to heat treatments at 40/42/44 °C for 20 min in the dark and(More)
Hordeum vulgare L. cv. Bartom seedlings grown on a substrate without or with zeolite were exposed to 450 and 1,000 µmol of Cd(NO3)2. Adding the zeolite to a substrate (+Si) resulted in the accumulation of mono- and polysilicic acids in the leaves, an increase in the growth of seedlings and biomass production, a decrease of the contents of thiobarbituric(More)
Barley (Hordeum vulgare L.) was grown in pots with brown loess soil and highly soluble amorphous silicon dioxide as the source of monosilicic acid to examine its influence on plant growth and adaptive potential under optimal soil watering and flooding. The adaptive potential of plants was estimated by the concentration of the thiobarbituric acid reactive(More)
Bean (Phaseolus vulgaris L. cv. Berbukskaya) seedlings were pre-treated with choline compounds, 19 mM 2-ethyltrimethylammonium chloride (Ch) or 1.6 mM 2-chloroethyltrimethylammonium chloride (CCh), during 24 h, then after 6 d the excised primary leaves were exposed to UV-B and high temperature stress. Chlorophyll (Chl) fluorescence, delayed light emission,(More)
Barley (Hordeum vulgare L.) seeds were soaked in aqueous 10−4 M dihydroquercetin (DHQ) to examine its influence on seed germination and further growth of seedlings under optimal soil watering and flooding conditions. The adaptive potential of the plants was estimated by the content of thiobarbituric acid reactive substances (TBARs) and the activity of(More)
In this work we analyzed the results of the transformation of tomato plants Solanum lycopersicum by gene FeSOD1 from Arabidopsis thaliana, equipped with the signal sequence for targeting into chloroplasts. PCR analysis showed that the gene was integrated into the genome of several tomato plants that underwent transformation followed by selection in the(More)
The dynamics of development of oxidative stress and poststress recovery of the photosynthetic apparatus in leaves of 10-day-old wheat seedlings subjected to heat shock (40, 42, and 44°C) for 20 min and exposed to light for 72 h are studied. The effect of pretreatment temperature and light intensity on recovery of the photosynthetic apparatus and its(More)
