Summary: This study examines the relationship between the climate of countries where wheat landraces are adapted and their agronomic and grain quality characteristics. The research found that the agronomic performance of landraces varied according to different climatic regions within the Mediterranean Basin. However, there was no geographical pattern in grain quality related to climate. Molecular analysis revealed that genetic structure was influenced by temperature and rainfall before and after anthesis.

Summary: Average grain weight is a major factor in wheat yield and understanding the distribution of individual grain weights is crucial for research on treatment effects. Grain area was found to be a better predictor of weight than length or width. A power curve model was established to reliably estimate individual grain weight from measured areas, validated with diverse data sources.

Summary: Foliar diseases such as Puccinia graminis and Zymoseptoria tritici have detrimental effects on wheat yield and milling and breadmaking attributes. P.graminis causes the greatest reduction in yield, while both diseases reduce milling yield and protein content. Zymoseptoria tritici has no effect on breadmaking quality, but P.graminis affects some parameters such as loaf volume.

Summary: In this study, the interactive effects of ozone, temperature, and water supply on wheat yield and grain quality were assessed. It was found that ozone, warming, and drought all decreased grain yield and average grain mass but increased grain concentration of nutrients. The results highlight the importance of considering water availability when assessing the impact of ozone on global food production.

Summary: Drought is a major limitation for sustainable agricultural production, particularly affecting the quality and quantity of bread wheat yield during flowering. Through studying contrasting wheat cultivars, it was found that the sensitive cultivar showed ineffective water management and a decline in photosynthesis, while the tolerant cultivar used photorespiration to dissipate excessive light energy and induced superoxide dismutase for a less inhibited photosynthesis. The tolerant cultivar also exhibited a more stable gluten profile and accumulation of specific proteins, indicating its potential as a marker for drought tolerance in breeding.

Summary: The study found that planting winter wheat after soybean resulted in significantly higher grain and straw yield, as well as improved quality parameters compared to planting after winter oilseed rape. The tillage system did not have a significant impact on winter wheat grain yield, but conventional tillage system was beneficial for increasing straw yield and plant height, while the no-tillage system improved the thousand grain weight. Wheat grain harvested under conventional tillage system had better test weight, grain uniformity, and lower gluten index than under no-tillage.

Summary: This study mapped QTL for canopy activity related traits in wheat using three RIL populations, identifying 12 QTL clusters related to grain yield traits. The relationship between NDVI-S and TKW was discovered, and stable QTL like QNDVI-S.caas-1AL and QNDVI-10.caas-3B can assist in identifying lines with high NDVI. The research provides new insights into the genetic architecture of wheat yield based on canopy activity traits.

Summary: The study evaluated the model efficiency of HYDRUS 2D/3D simulations for volumetric water content and pore electrical conductivity in an olive tree variety under desert conditions. The model simulations were improved through calibration using PEST software. The sensitivity analysis identified relevant parameters for the model outputs and calibration focused on those parameters. Overall, the HYDRUS 2D/3D simulations showed acceptable precision for the variation of volumetric water content in time and space.

Summary: Anthropogenic disturbances can alter the relationships between peatland soil and plants, affecting their ability to store carbon. This study examined a peatland in Northern Patagonia and found that aboveground vegetation attributes were directly and indirectly related to soil carbon pools. Disturbed areas had significantly lower levels of live moss, debris, and poorly-decomposed carbon pools compared to undisturbed areas.

Summary: This study used a panel of 316 spring bread wheat cultivars to develop a spectral-based classification approach for assigning cultivars to genetically differentiated subpopulations. The results demonstrated that the Convolutional Neural Network (CNN) had the highest accuracy in classifying individuals, with 92% and 93% correct assignments in water-limited and fully irrigated environments, respectively. This indicates that foliar spectral variation can accurately determine the genetic group of a cultivar, even in different environmental conditions.

Summary: Climate change poses a significant challenge to food production, especially in Mediterranean climate regions. This study examined the impact of a prolonged drought on the persistence and productivity of an alfalfa diversity panel in central Chile. The study found large variability in plant survival and productivity, with some accessions exhibiting high drought tolerance and forage yield. The use of remote sensing technologies, such as NDVI sensors and RGB and thermal cameras, proved effective in evaluating canopy traits and predicting forage yield.

Summary: Determining soil water content in forest ecosystems is challenging due to deep rooting systems and unknown soil heterogeneity. This study tests two undisturbed methods, electrical resistivity tomography (ERT) and HYDRUS 2D/3D, for 2D water content determination in a thorny forest ecosystem. The results show that both methods are alternative approaches for determining soil water content in heterogeneous and deep soils of forest ecosystems.
