Journal ArticleDOI
Oxidative stress and some antioxidant systems in acid rain-treated bean plants Protective role of exogenous polyamines
TL;DR: In this article, the effect of simulated acid rain (AR) on H2O2 and malonyldialdehyde (MDA) levels and activities of peroxidase and catalase in bean plants were investigated.
Journal ArticleDOI
Plant Responses to Drought, Acclimation, and Stress Tolerance
TL;DR: The analysed literature shows that plants have evolved a number of adaptive mechanisms that allow the photochemical and biochemical systems to cope with negative changes in environment, including increased water deficit.
Journal ArticleDOI
Drought-induced modifications of photosynthetic electron transport in intact leaves: Analysis and use of neural networks as a tool for a rapid non-invasive estimation
Vasilij Goltsev,Ivelina Zaharieva,Petko Chernev,Margarita Kouzmanova,Hazem M. Kalaji,I. Yordanov,Vassilena Krasteva,Vladimir Alexandrov,Detelin Stefanov,Suleyman I. Allakhverdiev,Reto J. Strasser +10 more
TL;DR: This work uses simultaneously recorded signals of photoinduced prompt fluorescence and delayed fluorescence as well as modulated reflection of light at 820nm for analysis of the changes in the photosynthetic activity in detached bean leaves during drying to demonstrate that this is a reliable method for determination of RWC in detached leaves.
Journal ArticleDOI
Effects of Water Stress and High-Temperature Stress on the Structure and Activity of Photosynthetic Apparatus of Zea Mays and Helianthus Annuus
TL;DR: Effects of high-temperature stress (HTS) and PEG-induced water stress (WS), applied separately or in combination, on the functional activity and ultrastructure of the photosynthetic apparatus (PSA) of maize and sunflower plants were investigated.
Journal ArticleDOI
Simultaneous analysis of prompt and delayed chlorophyll a fluorescence in leaves during the induction period of dark to light adaptation
Vassilij Goltsev,Ivelina Zaharieva,Ivelina Zaharieva,Petar H. Lambrev,Petar H. Lambrev,I. Yordanov,Reto J. Strasser +6 more
TL;DR: An attempt is made to reveal the relation between the induction curves of delayed fluorescence registered at 0.35-5.5 ms and the prompt chlorophyll fluorescence (PF), and it was shown that UL is proportional to the ratio of DF to the variable part of PF.
