Abstract Extremely high temperatures represent one of the most severe abiotic stresses limiting crop productivity. However, understanding responses to heat stress is still limited considering increases in both frequency and severity wave events under climate change. This partly due lack studies or tools for timely accurate monitoring extreme over broad spatial scales. In this work, we use novel spaceborne data sun‐induced chlorophyll fluorescence (SIF), which a new proxy photosynthetic...
Abstract Gross primary productivity (GPP) is the largest flux in global terrestrial carbon cycle. Drought has significantly impacted GPP recent decades, and been projected to occur with increasing frequency intensity. However, drought risk of not well investigated. In this study, during 1981–2016 was simulated process‐based Boreal Ecosystem Productivity Simulator model. Then, quantified as product probability reduction caused by drought, which determined using standardized precipitation...
Abstract Recently, severe droughts that occurred in North America are likely to have impacted its terrestrial carbon sink. However, process‐based understanding of how meteorological conditions prior the onset drought, for instance warm or cold springs, affect drought‐induced cycle effects remains scarce. Here we assess and compare response fluxes summer 2011 2012 characterized by contrasting spring conditions. The analysis is based on a comprehensive ensemble models, including FLUXCOM,...
Photosynthetic capacity (leaf maximum carboxylation rate, Vcmax) is a critical parameter for accurately assessing carbon assimilation by plant canopies. Recent studies of sun-induced chlorophyll fluorescence (SIF) have shown potential estimating Vcmax at the ecosystem level. However, relationship between SIF and leaf canopy levels still poorly understood. In this study, we investigated dynamic its controlling factors using CO2 response measurements in rice paddy. We found that yield (SIFy)...
Sheath blight (ShB), caused by Rhizoctonia solani, is one of the major threats to rice (Oryza sativa L.) production. However, it not clear how risk ShB will respond elevated CO2 and temperature under future climate change. Here, we conducted, field experiments inoculated R. solani combinations two levels (ambient enriched up 590 μmol mol-1) increased 2.0°C) in free-air enrichment (T-FACE) system for cultivars (a susceptible cultivar, Lemont a resistant YSBR1). Results indicate that...
Abstract Increased rice yields due to rising atmospheric carbon dioxide (CO 2 ), known as the CO fertilization effect (CFE), is one of several important factors sustaining global food security. However, model projections on future are still largely uncertain, partly owing lack how CFE varies between species. Here, through synthesis hundreds field observations, we found experimental evidence a 12.8 ± 0.8% yield increase per 100 ppm for Indica, but only about half Japonica (6.3 0.5 %). After...
Rising global atmospheric carbon dioxide (CO2) concentrations and surface temperatures could negatively affect rice yields nutritional quality; however, their effects on arsenic accumulation in paddy have not been assessed concurrently. We aimed to assess the impact of increases CO2 temperature (individually combination) rice, characterise soil properties that might influence uptake, model associated risks cancer other health outcomes due increased exposure. For this modelling study we...
Abstract Photosynthesis under fluctuating irradiance is understudied, especially with regard to its response elevated CO2 and temperature in field environments. We measured photosynthesis after a single-step change during series of lightflecks for rice (Oryza sativa L.) grown combinations two levels (ambient by 200 μmol mol-1) increased 2.0 °C) free-air enrichment systems years. The cumulative fixation (CCF) increase were linearly correlated final steady-state at the high (Anf) both Across...
Sensing and classification of drought stress levels are very important to agricultural production. In this work, rice were classified based on the commonly used chlorophyll
With the aim of improving poplar timber production, a successive 8-year irrigation and fertilization factorial experiment with three blocks was designed to measure response Populus tomentosa stands water nitrogen in Huabei Plain, China. Specifically, we examined responses four P. clones (P. BT17, S86, B331, 1316) levels (45%, 60%, 75% above field capacity), as thresholds, N (0, 80, 160, 240 g per plant). The results showed that both had significant effects terms clone stand volume. Further,...
Abstract Understanding how humanity’s influence on the climate affects rainfall seasonality around world is immensely important for agriculture production, ecology protection, and freshwater resource management. In this study, we qualitatively quantitatively analyzed potential of anthropogenic forcing in global land monsoon (GM) regions using Coupled Model Intercomparison Project Phase 5 (CMIP5) general circulation models. We discovered that enhances over many parts GM regions, was evident...
Sun-induced fluorescence (SIF) is a novel remote sensing method, which can be potentially used as direct indicator of photosynthetic activity. In this study, we present an approach for generating consistent long-term global SIF product (2003-2015) by combining Scanning Imaging Absorption Spectrometer Atmospheric Chartography (SCIAMACHY) and the Global Ozone Monitoring Experiment -2 (GOME-2). The relationships between SCIAMACHY (2003-2011) GOME-2 (2007-2015) were established pixel using two...
