MORENO ROBLERO, Mario de Jesús; PINEDA PINEDA, Joel; COLINAS LEON, María Teresa  e  SAHAGUN CASTELLANOS, Jaime. Oxygen in the root zone and its effect on plants. Rev. Mex. Cienc. Agríc [online]. 2020, vol.11, n.4, pp.931-943.  Epub 13-Set-2021. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v11i4.2128.

The information presented analyzes the state of the art of the evidence in the last 20 years of the importance and the effects of the availability of oxygen in the rhizosphere on the growth and development of plants. Adverse conditions of biotic (microorganisms) and abiotic factors (temperature, waterlogging, salinity, others) that influence the oxygen concentration in the rhizosphere, can lead to a rapid drop in oxygen levels and affect morphology, metabolism and physiology from the roots, with a negative effect on the growth of the plant. Radiation medium oxygenation techniques can be favorable, both in soils and in substrates, in situations where there is a risk of hypoxia, but specific studies are required on the effect of oxygen application in each species, as well as the measurement of the answers to identify the oxygen requirements that maximize the yield and quality of the harvested products, both in the field and in the greenhouse. In the agricultural sector, techniques that are sustainable and economically viable are required, even with the high costs of using new technologies.

Palavras-chave : anoxia; hypoxia; oxygenation.
