Flooding Tolerance in Rice: Focus on Mechanisms and Approaches
WEBJan 1, 2021 · Flooding is one of the most hazardous natural disasters and a major stress constraint to rice production throughout the world, which results in huge economic loss. Approximately one-fourth of the global rice crops (approximately 40 million hectares) are grown in rainfed lowland plots that are prone to seasonal flooding.
Flooded rice systems: Emissions & mitigation strategies » AgLED
WEBWhat is flooded rice? Flooded rice systems, a type of paddy rice, are irrigated, rainfed, or deep-water rice production systems with a growing cycle of approximately 105-150 days, depending on the variety. Flooded rice is cultivated for up …
Deepwater rice - Wikipedia
WEBDeepwater rice are varieties of rice (Oryza sativa) grown in flooded conditions with water more than 50 cm (20 in) deep for at least a month. More than 100 million people in Southeast Asia including Northeastern India rely on deepwater rice for their sustenance. [2]
Paddy field - Wikipedia
WEBA paddy field is a flooded field of arable land used for growing semiaquatic crops, most notably rice and taro. It originates from the Neolithic rice-farming cultures of the Yangtze River basin in southern China, associated with pre-Austronesian and Hmong-Mien cultures.
Greenhouse gas emissions and mitigation in rice agriculture
WEBSep 26, 2023 · Increasing harvest index and increasing rice plant biomass reduce CH 4 emissions in continuously flooded rice paddies and in paddies with high soil organic carbon contents, respectively.
Agro-technologies for greenhouse gases mitigation in flooded rice ...
WEBAbstract. We investigated methane (CH 4) and nitrous oxide (N 2 O), two important greenhouse gases (GHGs) emissions using the closed chamber method from a flooded rice field in Brahmaputra valley of Assam, northeast part of India.
Flooding or submergence - IRRI Rice Knowledge Bank
WEBFlooding can occur anywhere where water can be backed up. Rice stems have nodes, which break when there is tremendous pressure due to strong wind/rainfall occur. Cloudiness lessens the process of food-producing photosynthesis. Less sunlight makes rice plant to weaken and lodge.
Water management - IRRI Rice Knowledge Bank
WEBRice is typically grown in bunded fields that are continuously flooded up to 7−10 days before harvest. Continuous flooding helps ensure sufficient water and control weeds. Lowland rice requires a lot of water.
Flooding tolerance in Rice: adaptive mechanism and marker
WEBJan 2, 2023 · A marker-assisted backcrossing approach has been widely applied to develop flood-tolerant rice varieties to mitigate flood stress. In addition, genome editing techniques, especially the CRISPR/Cas9 system, widely applied based on engineered site-specific nucleases, have recently been dramatically enhanced.
