Summary: The wide-narrow-row planting pattern significantly improved the photosynthetic capacity of maize, along with an increase in stomatal conductance (Gs), transpiration rate (Tr), and photosynthetic rate (Pn). Among different parameters, D-M6S6 treatment showed the most significant effect on photochemical quenching, actual photochemical efficiency, and maximum photochemical efficiency. Therefore, intercropping six rows of maize and six rows of soybean based on the wide-narrow-row planting pattern is recommended in semi-arid regions of western China.

Summary: The aim of this study was to evaluate the development of maize varieties under different conditions of phosphorus availability, providing a new perspective for future studies that seek to increase phosphorus availability to plants. In low availability, there is a negative feedback control of photoassimilates export, which results in reduced photosynthesis, growth, and biomass accumulation. The relationship between photosynthesis and biomass accumulation can vary depending on the genetic composition.

Summary: Improvements in agricultural production are necessary due to the increasing human population and its impact on climate. Water scarcity limits maize yield in many regions. Seed mortars, particularly those containing succinate dehydrogenase inhibitors, can mitigate the negative effects of drought on maize development. This study compared 12 seed treatments and found that treatments with SDHI significantly improved root system development, photosynthesis, and chlorophyll fluorescence parameters in maize under drought stress.

Summary: Soil degradation caused by conventional cropping systems focused on maximizing profit can be mitigated by adopting integrated cropping systems that reduce chemical inputs. A study comparing winter triticale cultivation under conventional and integrated systems found that the former resulted in higher grain yield and protein content, while the latter exhibited better physiological parameters. Therefore, selecting appropriate cultivars for specific agronomic conditions can lead to sustainable agricultural practices and high-quality grain production.

Summary: Waterlogging adversely affects the growth and photosynthesis of cucumber, inhibiting biomass accumulation and carbon assimilation. The light- and carbon-dependent reactions of photosynthesis show differential responses to waterlogging stress. Waterlogging also affects the photochemical apparatus of cucumber plants, reducing the PSII quantum yield and altering the redox state of the primary quinone acceptor.

Summary: The maize genotype DKC7221 is more heat tolerant due to higher photosynthetic activity, while genotype P3167 is sensitive to high temperature with inhibited photosynthetic electron transport reactions. The study revealed that DKC7221 maintained photosynthetic efficiency under heat stress, while P3167 suffered oxidative stress and photooxidative injuries due to impaired photosynthetic efficiency.

Summary: Photosynthesis is a crucial metabolic pathway for plant growth and biomass production. Environmental adversities negatively affect photosynthetic activity, but plants have mechanisms to cope with these changes. Researching different methods to assess photosynthesis is important for understanding plant physiology and improving crop yield.

Summary: This study characterized a yellow-green leaf mutant in maize caused by a mutation in the ZmCAO1 gene, which encodes chlorophyll a oxygenase. The mutant exhibited reduced chlorophyll concentrations, affecting photosynthetic processes and plant growth. Additionally, the mutation led to decreased grain yield and waterlogging sensitivity in maize, highlighting the pleiotropic role of ZmCAO1 in photosynthesis and stress tolerance.

Summary: This study simulates the direct exposure of citrus plants to glyphosate, and finds that high dosages of glyphosate can disrupt the shikimate pathway and photosynthesis in citrus plants, leading to photooxidative damage and reduced fruit yield.

Summary: The study investigated the physiological status of S. hermaphrodita plantations growing on two different marginal lands, one contaminated with heavy metals and one nutrient-poor sandy soil. Higher biomass yield was found on the heavy metal contaminated site, indicating that soil quality was the main factor affecting yield. S. hermaphrodita is a more suitable option for fertile but heavy metal polluted soils, but further research on biomass quality is needed.

Summary: Due to water restrictions caused by climate changes, safflower is favored as an alternative crop due to its adaptability to restricted soil and climate conditions. This study evaluated the physiological and yield performance of four safflower lines under two water regimes. Water deficiency decreased various physiological variables and yield components, while some lines showed tolerance and recovery after rehydration. These lines can be recommended for commercial use and breeding programs targeting drought-tolerant genotypes.

Summary: This study aimed to determine the effects of the integrated system (INTEG) and conventional system (CONV) on physiological parameters, yield, and mineral composition of winter wheat. Results showed that the CONV system had more favorable physiological parameters and grain yield. The use of the CONV system also resulted in increased grain quality traits and protein content.

Summary: Researchers conducted a throughfall exclusion experiment to study the impact of extreme drought on mature forest trees. The findings showed that drought led to reduced tree growth and fine root abundance, as well as changes in mycorrhizal community composition. Careful watering can quickly restore the water status of drought-stressed trees, but growth recovery remains slow.

Summary: Research showed that mature beech and spruce trees responded differently in terms of carbon dynamics under drought, with no significant impact on NSC concentrations. However, whole-tree NSC pool size significantly decreased under drought, leading to a significant decline in overall growth compared to control trees.

Summary: Quantifying CO2 fluxes between soil and atmosphere is crucial for understanding carbon cycling in plant-soil systems. In this study, a simplified gas sampling system was developed to measure low soil CO2 fluxes and isotopic labeling. The system showed sensitivity to minor changes in CO2 concentration and eliminated cross-contamination between samples. It offers a flexible and accessible solution for CO2 measurements in arid soils and plant-soil systems.
