“…Interestingly, tall fescue Festuca arundinacea leaves show a great decrease at all steps of OJIP and F300 parameters in response to high-temperature stress, but pre-acclimation treatment inhibit such declines (Hu et al, 2015). Intriguingly, Rapacz et al (2015) suggest that DI 0 /CS 0 values increase with increasing levels of PSII damage, which is the opposite to what we found (Fig. 2M).…”

Rapacz et al (2015) showed that DI 0 /RC parameter increase with increasing levels of PSII damage in wheat under low temperature.

“…Chlorophyll fluorescence is a non-invasive tool commonly used for determining the behavior of the photosynthetic apparatus of control and abiotic stressed plants (Gururani et al, 2015; Rapacz et al, 2015). Our group previously detected a reduction in Pi ABS , S m , and N parameters (related to the donor and acceptor sides of PSII) in rice leaves early infested by S. oryzae in IRGA 424 cultivar (Buffon et al, 2016).…”

6Infestation of Schizotetranychus oryzae (Acari: Tetranychidae) causes great losses in 3 7 rice productivity. Infestation in Puitá INTA-CL cultivar reduced the number of 3 8 seeds/plant, percentage of full seeds, 1,000 seeds weight, and seed length, whereas 3 9 infestation in IRGA423 increased 1,000 seeds weight and seed length. Reduction in 4 0 seed weight/plant caused by infestation was higher in Puitá INTA-CL than IRGA423. 4 1 Thus, Puitá INTA-CL was established as susceptible, and IRGA423 as tolerant to S. 4 2 oryzae infestation. Photosynthetic parameters were less affected by infestation in 4 3 IRGA423 than in Puitá INTA-CL. Infestation also caused accumulation of H 2 O 2 , 4 4 decreased cell membrane integrity and accelerated senescence in leaves of Puitá INTA-4 5 CL, while leaves of IRGA423 presented higher levels of phenolics compounds. Using 4 6 proteomic analysis, we identified proteins related to plant defense, such as jasmonate 4 7 synthesis, and related to other mechanisms of tolerance such as oxidative stress, 4 8 photosynthesis, and DNA structure maintenance, more abundant in IRGA423 after 4 9 7 1damage caused by arthropod pests can exceed 15% annually (Mitchell et al., 2016). In 7 2 order to quantify the pest resistance of the cultivars, the best tool does not seem to be 7 3 the increase of the arthropod population, but the measurement of the damages caused to 7 4 the plants, since the reduction of the leaf damage is followed by an increase in yield and 7 5 quality of the grain, and these are the ultimate objectives of most crop breeding 7 6 programs (Smith, 2005). Thus, the plant resistance/tolerance to arthropods is the sum of 7 7 genetically inherited traits that result in an adapted species that suffers less damage 7 8 compared to susceptible ones. These resistance/tolerance qualities should be measured 7 9 on a relative scale by comparing levels of damage and productivity with susceptible 8 0

“…The results obtained in our work are consistent with other studies because fluorescence measurements have already been used to determine any differences in the frost tolerance of winter wheat (also in field testing). The results obtained by Rapacz, Sasal, Kalaji, and Ko scielniak (2015) showed that the OJIP test (fast fluorescence kinetic measurements) is a reliable indicator of the winter hardiness and freezing tolerance of common winter wheat and Triticale under unstable winter environments (field testing).…”

Comparative studies in winter wheat cultivars have so far been focused on the content of tocopherols in the grains as tocopherols are an important source of vitamin E in the human diet. Our approach was to verify the following main hypothesis—whether a higher accumulation of nonenzymatic antioxidants (tocopherol, tocotrienols, β‐carotene) in the leaves of winter wheat during cold acclimation is accompanied by a higher frost tolerance of winter wheat cultivars. Seedlings of winter wheat cultivars—frost susceptible (Bystra) and frost tolerant (Nutka and Smuga)—were cold acclimated for a period of 3 weeks. To analyse the antioxidants (tocotrienols, tocopherols, β‐carotene), leaf samples were taken on the final day of the exposure to cold. Moreover, samples were also taken to estimate the content of abscisic acid, jasmonic acid and salicylic acid. After leaf chlorophyll a fluorescence measurements, the plants were exposed to frost (−8 to −14°C) and left to regrow to estimate their survival. Cultivars of winter wheat with higher accumulation of tocopherols in leaves had higher frost tolerance than cultivar with fewer tocopherols in leaves. α‐tocopherol was accumulated in cv. Bystra in the amount of 137 μg g DW−1. The content of α‐tocopherol was about 26% and 90% higher in cv. Nutka and cv. Smuga, respectively. The β‐carotene content was also higher in cv. Nutka and cv. Smuga compared to cv. Bystra. This work indicates a need for further and more detailed studies on the role of tocopherols and carotenoids in the acclimation process of cereals (winter wheat) to low temperatures. The accumulation of nonenzymatic antioxidants in the cold acclimation process will be discussed against the background of the accumulation of the stress hormones and changes in the photosynthetic efficiency in the tested cultivars.

“…The studies include e.g., high light stress (Oukarroum and Strasser 2004), nitrogen deficiency (Cetner et al 2017, Samborska et al 2018, salinity (Dąbrowski et al 2016), water deficit, drought stress (Kiani et al 2008, Czyczyło-Mysza et al 2011, Wang et al 2012, Jedmowski et al 2014, Rapacz et al 2019, action of herbicides (Lazár et al 1997a(Lazár et al , 1998, and waterlogging (Bertholdsson et al 2015). The studies focused on temperature effects on OJIP shape and derived parameters have addressed both low (e.g., Fracheboud et al 1999, Rapacz et al 2015, Husičková et al 2019 and high (Pastenes andHorton 1996, Azam et al 2015) temperature.…”

In this study, we evaluated the effect of temperature on the fast chlorophyll fluorescence (ChlF) transient (OJIP) and OJIP-derived parameters in Antarctic lichens Xanthoria elegans, Usnea antarctica, and Dermatocarpon polyphyllizum. Samples were exposed to a range of temperatures (-5 to +45°C) and measured after 15-min equilibration. High temperature (+45°C) caused a decrease of ChlF, an increased J-step, and shortened time to reach peak ChlF (FP). Temperature below +5°C caused the increase of ChlF and J-step. The K-band was identified in X. elegans (above +20°C), U. antarctica (+35°C), and D. polyphyllizum (+45°C). L-band was well distinguishable in X. elegans (+45°C). As indicated by the OJIP-derived parameters, high temperature inhibited photosystem II function. The inhibition was apparent as less effective energetic connectivity. The OJIP transients and auxiliary measurement of ChlF temperature curves suggested that X. elegans had the lowest termostability among the experimental species.
