Summary: Understanding the impacts of rising temperature and elevated [CO2] on different crop cultivars is crucial for adapting to climate change. Simulation and pot experiments were conducted to study the growth and yield of two wheat cultivars under elevated [CO2] and 2 degrees C warming. It was found that the early-maturing cultivar was better adapted to elevated [CO2] and rising temperature than the late-maturing one.

Summary: Elevated carbon dioxide concentration has effects on carbon fluxes and sequestration in agroecosystems. A two-year field experiment was conducted to investigate the characteristics and factors influencing carbon fluxes in winter wheat fields. The results showed that increased carbon dioxide concentration enhanced the biomass and carbon accumulation in the wheat fields. The findings suggest that elevated carbon dioxide concentration may have feedback to the climate system in the future.

Summary: Projected global climate change poses a potential threat to nutrient utilization in agroecosystems. However, the combined effects of elevated [CO2] and canopy warming on nutrient concentrations and translocations in plants are not well understood. This study conducted an open-air field experiment to investigate the impact of elevated [CO2] and canopy air warming on nutrient status during the growing season of winter wheat. The results showed that canopy warming played a more important role in nutrient translocation from belowground to aboveground than elevated [CO2].

Summary: The intensity and frequency of extreme drought are increasing worldwide, but elevated CO2 concentration can mitigate the negative impacts of water shortage. However, wheat genotypes have different reactions to CO2. Root system development plays a key role in abiotic stress resistance.

Summary: Increases in atmospheric CO2 can promote plant growth under heavy metals stress conditions, but the mitigating effect of vanadium (V) stress under enhanced CO2 levels has not been well studied. This study investigated the growth and biochemical responses of wheat plants under V and enhanced CO2 conditions, and found that high V levels inhibited plant growth and induced oxidative damage. However, under enhanced CO2, wheat showed reduced V uptake and toxicity, leading to improved growth through increased photosynthesis and enhanced antioxidant production.

Summary: This study found that elevated CO2 concentrations can promote the mineralization of organic phosphorus in the rhizosphere, leading to changes in bacterial and fungal communities. Under eCO(2), increased carbon supply to plants allows symbiotic mycorrhizal fungi to better compete for and mineralize organic phosphorus. The results of this study are important for understanding the impact of climate change on phosphorus cycling in agricultural systems.

Summary: Delineating root-water-uptake (RWU) under conditions with augmented CO2 concentrations is crucial for irrigation scheduling in response to climate change. The effects of increased CO2 concentration (e[CO2]) on RWU and the development of a RWU model were studied through two experiments, which demonstrated the stimulation of plant growth and the decrease in RWU activity under e[CO2]. The RWU model accurately simulated soil water transport and wheat transpiration under e[CO2].

Summary: Global warming will inevitably impact crop production and development, but utilizing genotypic variability to select improved crop varieties can help mitigate the adverse effects of climate change. Research shows that different wheat genotypes exhibit varying yield performances under elevated CO2 and high-temperature conditions, with some genotypes showing better adaptation to these environmental factors.

Summary: The study found a close relationship between chlorophyll content of winter wheat and spectral reflectance under elevated CO2 conditions, with better estimation accuracy using sensitive spectral bands and difference vegetation index (DVI). Hyperspectral measurement can effectively estimate chlorophyll content and serve as a useful tool for monitoring plant physiology and growth under both ambient and elevated CO2 conditions.

Summary: China's surface air temperature is projected to increase due to global warming, which could have implications for the growth of winter wheat. The study focused on the low temperatures of winter wheat from 2021 to 2050 and found that the mean temperature is expected to rise, with a greater increase in the northern region. The warmer spring temperatures could advance the flowering and grain-filling period, but it could also expose the winter wheat to more low-temperature days and potentially negative effects. The findings emphasize the need to consider the response of winter wheat growth to global warming when assessing the impact of low temperatures.

Summary: Field crop production needs to adapt to challenges brought by climate change. This study investigated the responses of wheat, barley, and oat varieties to increased CO2 concentration and simulated drought. Results showed positive CO2 responses in barley, while water uptake in all wheat cultivars decreased significantly but water-use efficiency improved under 1000 ppm CO2.

Summary: Global rising atmospheric CO2 concentration and drought stress have profound effects on crop growth and yield. The responses of wheat and maize plants to progressive drought stress under different atmospheric CO2 concentrations were investigated in this study. Different water management strategies should be developed to optimize crop water use efficiency in the future drier and CO2-enrich environment.

Summary: In a field setting, elevated atmospheric CO2 and silicon supplementation increased plant biomass, while herbivory reduced it and induced silicon accumulation. However, increased atmospheric CO2 concentrations resulted in decreased shoot silicon concentrations. Additionally, endophytic fungi negatively impacted phosphorus uptake.
