“…GPX activity (Fig. 3) that typically shows the highest value among various antioxidative enzymes, fits well with shoot and root values reported in Si-treated barley (Balakhnina et al, 2012). Fluorescence microscopy is a modern and effective tool allowing to see changes of target molecules within tissue that are unable to be obtained by quantitative methods such as spectrophotometry.…”

“…by 4.8 %, citrus species by 12.3 %, longan ( Dimocarpus longan Lour) by 10.7 %, tea ( Camelia sinensis ) by 11.0 %, ginseng ( Panax ginseng ) by 3.2 % and papaya ( Carica papaya ) by 9.7 % . Balakhnina et al ( 2012 ) observed that the application of Si stimulated the growth and biomass production of both shoot and roots in barley. In citrus, the application of Si fertilizers enhanced the growth by 30-80 %, promoted fruit maturation by 2-4 weeks and improved fruit quantity (Meena et al 2014 , and reference therein).…”

Silicon (Si) has widely been reported to increase the growth and biomass, yield and quality of a broad range of crops including monocotyledonous crops such as rice, wheat, maize, barley, millet, sorghum and sugarcane that actively take up and accumulate high amounts of Si in their organs and some dicotyledonous crops such as cotton and some vegetable and fruit crops. The yield increment, however, may be attributable not only to the benefi cial effects of Si including growth promotion, lodging resistance and biotic and abiotic stress resistance but also to some indirect effects such as pH adjustment and acquisition of macro-and micronutrients contained in the silicate fertilizers, especially when slags or Si-containing mineral ores are used as sources of silicate fertilizer.

“…Ascorbate peroxidise (AsP) and glutathione reductase (GR) activities and thiobarbituric acid reactive substances (TBARS) content were determined as described earlier (Balakhnina et al, 2009(Balakhnina et al, , 2012a(Balakhnina et al, , 2012b in enzymatic extracts and in crude homogenates of the top leaves. Middle fragments (0.5 g) of the fully developed leaves without the midrib were homogenized manually in a mortar with 4.5 ml of cooled 30 mM K/Na phosphate buffer, pH 7.4, containing 0.1 mM EDTA and 2% PVP (M.м.…”

A b s t r a c t. Fluctuation of the summer day-time temperatures in the mid-latitudes in a range from 16 to 30 o C should not have irreversible negative effects on plants, but may influence metabolic processes including the oxidative stress. To test the effect of moderately high temperature on oxidative stress induced by lead in the leaves of Plantago major L.; the plants were incubated in a water solution of 0, 150, 450, and 900 µM Pb(NO 3 ) 2 at 20 and 28 o C. Plant reactions were evaluated by the content of thiobarbituric acid reactive substances and ascorbate peroxidase and glutathione reductase activities in leaves after 2, 24, 48, and 72 h. The Pb concentration in the leaves rose with the increase in the Pb content and was higher at 20 o C. The increase in stomatal resistance caused by Pb was higher at 28 o C. The contents of TBARS increased after 2 h of plant exposure to Pb and the increase was the highest at 900 µM Pb, 28 o C. The AsP activity increased up to 50% after 24 h of Pb-treatment at 28 o C; the highest increase in glutathione reductase activity was observed after 72 h at 20 o C. Thus, the moderately high temperature 28 o C compared with optimal 20 o C caused a decrease in Pb accumulation in Plantago leaves but amplified the negative effects of lead, especially in the beginning of stress development.K e y w o r d s: ascorbate peroxidase, glutathione reductase, lead, heat stress, oxidative destruction, Plantago major L.
