“…Several studies have shown that the chlorophyll a transient has become one of the most popular tools to estimate stress-induced changes in photosynthetic performance. For example, the shape of the OJIP transient seems to be particularly sensitive to environmental stresses, such as drought [55], salt stress [56], high temperature [57], and heat stress [58]. The chlorophyll fluorescence parameter Fv/Fm has been used as an indicator of physiological stress.…”

“…The chlorophyll fluorescence parameter Fv/Fm has been used as an indicator of physiological stress. The experimental evidence has shown that Fv/Fm is often insensitive to stress and is not always a suitable parameter for screening stress tolerance [33,56]. Nonetheless, Fv/Fm reflects the maximum quantum efficiency of PSII photochemistry and has been widely used for early stress detection in plants [59].…”

Abstract:Plants can undergo external fluctuations in the natural light and dark cycle. The photosynthetic apparatus needs to operate in an appropriate manner to fluctuating environmental factors, especially in light. Yellow-poplar seedlings were exposed to nighttime artificial high-pressure sodium (HPS) lighting to evaluate night light-adaptation strategies for photosynthetic apparatus fitness relative to pigment contents, photosystem II photochemistry, photosynthetic parameters, histochemical analysis of reactive oxygen species, and plant biomass. As a result, seedlings exhibited dynamic changes including the enhancement of accessory pigments, the reduction of photosystem II photochemistry, increased stomatal limitation, downregulation of photosynthesis, and the decreased aboveground and belowground biomass under artificial night lighting. Histochemical analysis with 3,3 -diaminobenzidine (DAB) and nitroblue tetrazolium (NBT) staining indicates the accumulation of in situ superoxide radicals (O 2 − ) and hydrogen peroxide (H 2 O 2 ) in leaves exposed to the lowest level of artificial night lighting compared to control. Moreover, these leaves exposed to artificial night lighting had a lower nighttime respiration rate. These results indicated that HPS lighting during the night may act as a major factor as repressors of the fitness of photosynthesis and growth patterns, via a modification of the photosynthetic light harvesting apparatus.

“…Leaf or canopy gas exchange along with chlorophyll (Chl) fluorescence (ChlF) provides information on a wide range of key biophysical and biochemical limitations to photosynthesis in vivo (Long and Bernacchi 2003). The ChlF measurement may be considered as a powerful tool to assess plant vitality under unfavorable conditions because it is simple, noninvasive, reliable, powerful, inexpensive, and a rapid tool to analyze photosynthetic light-dependent reactions (Dąbrowski et al 2016. Hence, these measures are used in various fields, such as agriculture, ecology, and environmental studies, for example, photosynthetic adaptability of rye grass varieties to long-term shade (Dąbrowski et al 2015), photosynthetic acclimation in tor grass (Bąba et al 2016), water and drought stress in barley mutants (Janeczko et al 2016), and gas exchange, delayed Chl in a fluorescent ryegrass under salt stress (Dąbrowski et al 2017).…”

Waterlogging is one of the critical factors controlling the distribution, regeneration, and survival of vegetation in wetlands. Here, we tested the hypothesis that Mitragyna parvifolia (Roxb.) Korth. and Syzygium cumini Keels, inhabiting the Keoladeo National Park, a Ramsar wetland (Bharatpur, India), are tolerant to waterlogging. The morphological and photosynthetic variables of four-month-old seedlings subjected to waterlogging, along with the concentrations of macroand micronutrients, were examined. After 35 days, treatment was halted due to high mortality of S. cumini seedlings in contrast to that of M. parvifolia seedlings. Significant declines in most of the studied variables were observed in both species when compared with their respective controls. In addition, M. parvifolia seedlings developed adventitious roots and lenticels and showed an increased root biomass. Based on the results, we concluded that adaptive traits displayed by M. parvifolia seedlings facilitate its tolerance to waterlogging in contrast to S. cumini seedlings.

“…For some of the individual plant species, environmental factors are essential for life, and can even have very harmful effects of their development, while for other species they are less important. Adverse environmental factors such as drought (šimunić et al, 2007;Viljevac et al, 2012), extreme temperatures (Černý et al, 2011), heavy metals (Tuba et al, 2010;Mathur et al, 2016) and soil salinity (Yokoi et al, 2002;Dąbrowski et al, 2016) are stressful for many agronomic traits. Among abiotic stress factors, the most significant is drought, i.e.…”

“…In the past decade a very common method for determining photosynthetic efficiency was measuring chlorophyll a fluorescence, which is a noninvasive method that allows a quick assessment of the plant's physiological state . Under unfavourable environmental conditions this method estimates plant vitality (Dąbrowski et al, 2016) by detecting changes in the components of photosystem II, electron transport chain and photochemical reactions (borawska-Jarmułowicz et al, 2014). One of the most commonly applied photosynthetic parameters used to assess the condition of the plants is photosynthetic performance index (PI AbS ) (kalaji et al, 2016) which gives an insight into the overall flow of energy through the photosystem II (Force et al, 2003).…”

SUMMARYThe aim of this research was to investigate the variability of photosynthetic performance index (PI ABS ) and leaf temperature values measured in V6 development phase on 13 sunflower hybrids, grown in stressful conditions. The pot trial was made up of two treatments, one (T1) with 60% Field Water Capacity (FWC), and the other one (T2) with 80% FWC. Significant differences between T1 and T2 treatments were established for both of these parameters which prove their dependence on the water content in the soil, while the influence of hybrid was evident only in the case of PI ABS . Although in T1, as opposed to T2, all sunflower hybrids reacted by increasing leaf temperature, reaction to stress conditions measured with PI ABS parameter was not uniform. Some of the hybrids reacted by decreasing PI ABS values, while others reacted by increasing their PI ABS values. Therefore, it can be concluded that changes in parameters were independent of each other, which was confirmed by correlation analysis. Investigated parameters are suitable for determining the existence of undesirable environmental conditions that cause stress in plants and can be used in breeding of sunflower to withstand abiotic stress conditions, i.e. in selection of stress tolerant hybrids.
