We studied the effect of low above-zero temperature (2°C) on the content of low-molecular antioxidants (ascorbic acid, glutathione, and carotenoids) and also activities of antioxidant enzymes (ascorbate peroxidase, APO; catalase, CAT; glutathione reductase, GR; and superoxide dismutase, SOD) in green barley (Hordeum vulgare L.) seedlings. Under stress(More)
Effects of exogenous 5-aminolevulinic acid (ALA) on development and certain biochemical parameters of winter rape plants (Brassica napus L.) were studied. Plant growing on 50–200 mg/L ALA solutions for 7 days resulted in an accumulation of anthocyanins in cotyledonous leaves and changed in leaf color from green to violet. An application of 200 mg/L ALA(More)
The effects of overwatering (flooding) on the oxidative potential, the level of low-molecular-weight antioxidants, the content of stress proteins, and activities of antioxidant enzymes in green barley (Hordeum vulgare L.) seedlings were studied. Overwatering retarded barley seedling growth and induced hydrogen peroxide accumulation, a decrease in the total(More)
Chlorophyll (Chl) accumulation and delayed luminescence of PSII were compared in greening barley leaves pretreated and untreated with diuron (DCMU) in the etiolated state, and reactions of two photosystems were studied in the plastids isolated from the pretreated and untreated leaves. The effect of treatment in light of post-etiolated leaves after 40-h(More)
