Wheat, rice, maize, and soybean provide two-thirds of human caloric intake. Assessing the impact global temperature increase on production these crops is therefore critical to maintaining food supply, but different studies have yielded results. Here, we investigated impacts yields four by compiling extensive published results from analytical methods: grid-based local point-based models, statistical regressions, field-warming experiments. Results methods consistently showed negative crop...
Crop models of crop growth are increasingly used to quantify the impact global changes due climate or management. Therefore, accuracy simulation results is a major concern. Studies with ensembles can give valuable information about model and uncertainty, but such studies difficult organize have only recently begun. We report on largest ensemble study date, 27 wheat tested in four contrasting locations for their simulating multiple yield variables. The relative error averaged over was 24-38%...
Wheat grain protein concentration is an important determinant of wheat quality for human nutrition that often overlooked in efforts to improve crop production. We tested and applied a 32-multi-model ensemble simulate global yield changing climate. Potential benefits elevated atmospheric CO2 by 2050 on are likely be negated impacts from rising temperature changes rainfall, but with considerable disparities between regions. Grain yields expected lower more variable most low-rainfall regions,...
Understanding the drivers of yield levels under climate change is required to support adaptation planning and respond changing production risks. This study uses an ensemble crop models applied on a spatial grid quantify contributions various climatic past variability in grain maize winter wheat European cropping systems (1984-2009) impacts 2050. Results reveal that for current genotypes mix irrigated rainfed production, would lead losses gains wheat. Across Europe, average heat stress does...
Our objective was to investigate the determinants of genetic variation in N accumulation, partitioning and remobilization grain post-flowering associations with flag-leaf senescence, yield N% 16 wheat cultivars grown under high (HN) low (LN) conditions UK France. Overall, ranged leaf lamina accumulation at anthesis from 5.32 8.03 g m−2 HN 2.69 3.62 LN, for stem-and leaf-sheath 5.45 7.25 2.55 3.41 LN (P < 0.001). Cultivars index (proportion above-ground crop component) 0.37 0.42 0.34 0.40 LN;...
In plants, carbon and nitrogen (N) economies are intimately linked at the physiological biochemical level. The strong genetic negative correlation between grain yield protein concentration observed in various cereals is an illustration of this inter-relationship. Studies have shown that deviation from relationship (grain or GPD) has a basis, but its basis still poorly understood. This study analysed data on 27 genotypes grown multienvironment field trials, representing wide range...
Abstract Climate change impact assessments are plagued with uncertainties from many sources, such as climate projections or the inadequacies in structure and parameters of model. Previous studies tried to account for uncertainty one two these. Here, we developed a triple‐ensemble probabilistic assessment using seven crop models, multiple sets model eight contrasting together comprehensively these three important sources. We demonstrated approach assessing on barley growth yield at Jokioinen,...
Abstract The role of plasma membrane aquaporins (PIPs) in water relations Arabidopsis was studied by examining plants with reduced expression PIP1 and PIP2 aquaporins, produced crossing two different antisense lines. Compared controls, the double (dAS) had amounts osmotic hydraulic conductivity isolated root leaf protoplasts 5- to 30-fold. dAS a 3-fold decrease expressed on dry mass basis, but compensating 2.5-fold increase ratio. conductance area basis similar for compared control plants....
Abstract A functional explanation for the regulation of grain nitrogen (N) accumulation in cereal by environmental and genetic factors remains elusive. Here, new mechanistic hypotheses N are proposed tested wheat (Triticum aestivum). First, we experimentally hypothesis that is mostly source regulated. Four contrasting cultivars, terms their concentrations yield potentials, were grown with non-limiting supply. Grain number per ear was reduced removing top part at anthesis. Reduction gave a...
The genetic variability of the duration leaf senescence during grain filling has been shown to affect both carbon and nitrogen acquisition.In particular, maintaining green leaves possibly leads increased yield, but its associated effect on protein concentration not studied.The aim this study was dissect factors contributing correlations observed at phenotypic level between filling, concentration, yield in winter wheat.With view, an analysis quantitative trait locus (QTL) co-locations for...
Photosynthetic capacity is one of the most sensitive parameters in vegetation models and its relationship to leaf nitrogen content links carbon cycles. Process understanding for reliably predicting photosynthetic still missing. To advance this we have tested across C3 plant species coordination hypothesis, which assumes allocation processes such that photosynthesis tends be co-limited by ribulose-1,5-bisphosphate (RuBP) carboxylation regeneration. The hypothesis yields an analytical solution...
In monocarpic species, during the reproductive stage growing grains represent a strong sink for nitrogen (N) and trigger N remobilization from vegetative organs, which decreases canopy photosynthesis accelerates leaf senescence. The spatiotemporal distribution of in has not been described detail. Here, we investigated role local light environment on lamina mass per unit area (SLN) grain filling field-grown wheat (Triticum aestivum). addition, order to provide some insight into coordination...
Efforts to limit global warming below 2°C in relation the pre-industrial level are under way, accordance with 2015 Paris Agreement. However, most impact research on agriculture date has focused impacts of >2°C mean crop yields, and many previous studies did not focus sufficiently extreme events yield interannual variability. Here, latest climate scenarios from Half a degree Additional warming, Prognosis Projected Impacts (HAPPI) project, we evaluated Agreement range (1.5 2.0°C above period)...
