“…In contrast, Greer and Sicard (2009) did not find any significant effects of temperature increases from 24 to 28°C on grapevine photosynthesis. In agreement with the latter study, the impact of a 4°C increase in temperature was negligible compared with the effect of an increase of CO 2 levels up to 700 ppm in alfalfa (Sanz-Sáez et al 2010) and grapevine (Salazar-Parra et al 2015) plants. Therefore, although elevated temperature in the CC treatment may have partially contributed to the enhanced A N values, it is likely that the increase in CO 2 concentration was the main factor affecting photosynthetic rates under the present experimental conditions.…”

“…CO 2 concentration, temperature, and RH in the measurement chamber were set according to the respective growth conditions (375 ppm CO 2 , 45 % RH, and 24°C or 700 ppm CO 2 , 33 % RH, and 28°C for Curr and CC conditions, respectively). In addition, plants grown under Curr were also measured under CC in the measurement chamber to estimate the level of photosynthetic downregulation of plants grown under CC Salazar-Parra et al 2015). Net photosynthesis (A N ), transpiration (E), stomatal conductance (g S ), and sub-stomatal CO 2 concentration (C i ) were calculated.…”

“…Increases in the atmospheric CO 2 concentration enhance photosynthetic rates (A N ) and decrease transpiration (E) and stomatal conductance (g S ) over the short term (Drake et al 1997;Long et al 2004). However, during long-term exposure (days-weeks), these effects may, at least partly, be abolished by downregulation of photosynthesis Salazar-Parra et al 2015). On the other hand, lasting increases in C fixation in response to elevated atmospheric CO 2 levels have been reported for certain species (such as oak and soybean; Campbell et al 1990;Maroco et al 2002).…”

While photosynthetic responses to elevated CO2, elevated temperature, or water availability have previously been reported for grapevine as responses to single stress factors, reports on the combined effect of multiple stress factors are scarce. In the present work, we evaluated effects of simulated climate change [CC; 700 ppm CO2, 28/18 °C, and 33/53% relative humidity (RH), day/night] versus current conditions (375 ppm CO2, 24/14 °C, and 45/65% RH), water availability (well-irrigated vs. water deficit), and different types of soil textures (41, 19, and 8% of soil clay contents) on grapevine (Vitis vinifera L. cv. Tempranillo) photosynthesis. Plants were grown using the fruit-bearing cutting model. CC increased the photosynthetic activity of grapevine plants grown under well-watered conditions, but such beneficial effects of elevated CO2, elevated temperature, and low RH were abolished by water deficit. Under water-deficit conditions, plants subjected to CC conditions had similar photosynthetic rates as those grown under current conditions, despite their higher sub-stomatal CO2 concentrations. As expected, water deficit reduced photosynthetic activity in association with inducing stomatal closure that prevents water loss. Evidence for photosynthetic downregulation under elevated CO2 was observed, with decreases in photosynthetic capacity and leaf N content and increases in the C/N ratio in plants subjected to CC conditions. Soil texture had no marked effects on photosynthesis and did not modify the photosynthetic response to CC and water-deficit conditions. However, in mature well-irrigated plants grown in the soils with the highest sand content, an important decrease in stomatal conductance was observed as well as a slight decrease in the utilization of absorbed light in photosynthetic electron transport (measured as photochemical quenching), possibly related to a low water-retention capacity of these soils even under well-watered conditions.

“…Since plants with C3 photosynthetic metabolism are CO 2 limited, it is expected that any CO 2 increase would lead to higher photosynthetic rates (Salazar-Parra et al 2015) and growth, because of increased photochemical efficiency (Cordoba et al 2017). By contrast, plants with a C4 photosynthetic pathway manifest little response to elevated CO 2 as they have an internal mechanism to concentrate CO 2 at the site of CO 2 carboxylation (Ramesh et al 2017).…”

This work focuses on the investigation of competition interaction between C 3 crop barley (Hordeum vulgare L.) and C 4 weed barnyard grass (Echinochloa crus-galli L.) at 2 times higher than ambient [CO 2 ] and +4 0 C higher ambient temperature climate conditions. It was hypothesized that interspecific competition will change the response of the investigated plants to increased [CO 2 ] and temperature. The obtained results showed that in the current climate conditions, a higher biomass and photosynthetic rate and a lower antioxidant activity were detected for barley grown under interspecific competition effect. While in the warmed climate and under competition conditions opposite results were detected: a higher water use efficiency, a higher photosynthetic performance, a lower dissipated energy flux and a lower antioxidant enzymes activity were detected for barnyard grass plants. This study highlights that in the future climate conditions, barnyard grass will become more efficient in performance of the photosynthetic apparatus and it will suffer from lower oxidative stress caused by interspecific competition as compared to barley.

Influential factors of global change affect plant carbon uptake and biomass simultaneously. Although the effects from warming and precipitation change have been extensive studied separately, the responses of plant biomass, photosynthesis, and lipid peroxidation to the interaction of these factors are still not fully understood. In this study, we examined the physiological responses of two dominant plant species from grasslands of northern China with different functional traits to combinations of five simulated warming patterns and five simulated precipitation patterns in environment‐controlled chambers. Our results showed that the biomass, net CO 2 assimilation rate (P n), maximal efficiency of photosystem II photochemistry (F v/F m), and chlorophyll content (Chl) of Stipa grandis and Leymus chinensis were enhanced by moderate warming and plus precipitation, but they declined drastically with high temperature and drought. High temperature and drought also led to significant malondialdehyde (MDA) accumulation, which had a negative correlation with leaf biomass. The lower level of lipid peroxidation in leaves of S. grandis suggests that this species is better protected from oxidative damage under heat stress, drought stress and their interactive conditions than L. chinensis. Using the subordinate function values method, we found S. grandis to be more sensitive to climate change than L. chinensis and the gross biomass and root biomass of S. grandis and the leaf biomass of L. chinensis were most sensitive to climate change. Furthermore, the P n of both S. grandis and L. chinensis had a significant linear relationship with F v/F m and Chl, indicating that carbon assimilation may be caused by nonstomatal limitations.
