“…However, the maximum photochemical efficiency of PSII (F v /F m ) was not affected by salinity. This is along the mainstream reports on other species (Abadía et al, 1999;Jimenez et al, 1997), suggesting that PSII is not the main target of salinity stress. In agreement with the results of Thomas et al (2013), here no significant effect of biochar on F v /F m under salinity stress was found (Fig.…”

“…Pigment composition was measured in 0.60 cm 2 discs of youngest fully developed leaves of each plant group. The leaf discs were ground in a mortar with pure acetone and a pinch of sodium ascorbate as described by Abadía et al (1999). Pigment extracts were analysed by HPLC (De las Rivas et al 1989).…”

In the present research we studied the photosynthetic traits and protective mechanisms against oxidative stress in two maize (Zea mays L.) genotypes differing in chilling sensitivity (Z7, tolerant and Penjalinan, sensitive) subjected to 5 degrees C for 5 days, with or without pretreatment by drought. The drought pretreatment decreased the symptoms of chilling injury in Penjalinan plants estimated as necrotic leaf area and maximum quantum yield of photosystem II. Furthermore, drought pretreatment diminished the level of lipid peroxidation caused by chilling in Penjalinan plants. After one day of recovery from chilling the Z7 and drought-pretreated Penjalinan plants showed higher net photosynthesis rates than the non-drought-pretreated Penjalinan plants, thereby decreasing the probability of generating reactive oxygen species. The greater net photosynthesis was correlated with the greater NADP-malate dehydrogenase activity. No differences in either the de-epoxidation state of the xanthophyll cycle or the antioxidant enzyme activities were found among the chilled groups of plants. However, a drastic decrease in ascorbate content was observed in chilled Penjalinan plants without drought pretreatment. As we found an increase of H2O2 content after drought pretreatment, we suggest its involvement as a signal in the drought-enhanced chilling tolerance of maize.

Effect of elevated CO₂, temperature and limited water supply on antioxidant status during regrowth of nodulated alfalfa

Atmospheric CO2 is a major contributor to the greenhouse effect and is one of the main inducers of climate change. Previous studies with nodulated alfalfa plants have shown that elevated CO2 increased the growth of plants grown under well‐watered or limited water supply conditions. The beneficial effects of atmospheric CO2 enrichment included higher photosynthetic rates, growth and water‐use efficiency and an increase in the root/shoot ratio. However, at the moment, we do not have information on the possible implications of the beneficial effect of elevated CO2 as it may relate to a higher capacity of the violaxanthin–antheraxanthin–zeaxanthin (VAZ) cycle, the dissipation of excess radiation as heat and the effect on photooxidation, and to an improved leaf antioxidant system (Halliwell–Asada cycle). The aim of the present study was to determine the effects of the interaction between CO2 (ambient, around 350 vs 700 μmol mol−1), temperature (ambient vs ambient + 4°C) and water availability (well irrigated vs partially irrigated) on the leaf antioxidant status of nodulated alfalfa during regrowth. Parameters measured in this study included relative growth rate (RGR), H2O2 content, oxidative damage [measured as thiobarbituric acid‐reacting substances (TBARS)], leaf pigment composition (chlorophylls and xanthophylls), ascorbate (ASA) and glutathione pool levels and antioxidant enzymes. Our results revealed that during alfalfa regrowth, the effects of elevated CO2, limited water supply, temperature and their interactions on growth were not related to significant or general changes in leaf antioxidant capacity, H2O2 accumulation or oxidative stress (TBARS concentrations). The beneficial effects of CO2 enrichment in well‐watered and limited water‐subjected plants were not associated with an increase in the capacity of alfalfa leaves to dissipate excess radiation as heat through the VAZ cycle or with an increase in the antioxidant capacity, measured in terms of Halliwell–Asada cycle enzymes and antioxidant compounds. Furthermore, elevated CO2 did not affect RGRs during the last 15 days of regrowth and reduced the activity of several antioxidant enzymes (catalase, superoxide dismutase and glutathione reductase and ASA peroxidase in limited water‐subjected plants), suggesting a lower basal rate of oxygen activation and H2O2 formation, leading to a relaxation of the antioxidant system.
