Divergent effects of successive drought and flooding on photosynthesis in wheat and barley

Frontiers in Plant Science
Climate change is leading to increases in extreme weather events, notably increasing both droughts and floods, which undermine food security. Although each stress individually has been well studied, little is known about the response of cereals to ...

Growth and yield response of common buckwheat (Fagopyrum esculentum Moench) to waterlogging at different vegetative stages

Plant Production Science, 2019
This study identified timing (1st, 3rd, or 5th leaf stage) and duration (1, 3, 6, or 10 days) of waterlogging treatment during the vegetative stage that had the most severe effect on yield and elucidated yield determining process.

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

Advanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Revolutionising Agricultural Sustainability: New ‘Furrow Tillage’ can Mitigate Short‐Term Soil‐to‐Atmosphere CO2 Flux and Promote Soil‐Plant‐Microbe Health

Advanced Science, EarlyView.
Furrow tillage resolves the conventional‐vs.‐no‐tillage trade‐off by simultaneously cutting CO2 efflux to 2.0–3.0 g C m−2 d−1 and unlocking high nutrient availability for the rice rhizosphere. This scalable agronomic solution strengthens soil health, enhances plant physiology, reshapes microbial metabolism, and shifts paddy systems toward a net ...

Influência da turbidez da água do rio Tietê na ocorrência de plantas aquáticas Influence of Rio Tiete water turbidity on the occurrence of aquatic plants

Planta Daninha, 2005
As plantas aquáticas são estudadas como um efeito do desequilíbrio causado pela poluição e/ou alagamento dos rios. A quantidade excessiva de plantas, conseqüente desse desequilíbrio, dificulta a navegação e a produção de energia elétrica.
