Identificação De Genótipos De Feijoeiro Comum Tolerantes Ao Alumínio

Abstract: Este trabalho teve como objetivo identificar genótipos de feijão comum tolerantes ao alumínio, em solução nutritiva. O experimento foi conduzido em condições de casa de vegetação, na Universidade Federal do Tocantins – Campus Universitário de Gurupi – TO, em blocos inteiramente casualizados, com seis repetições e tratamentos dispostos em esquema fatorial constituído por 15 genótipos e quatro tratamentos: 0, 3 e 6 mg L-1 de alumínio em pH 4,0 ± 0,2 e 0 mg L-1 de alumínio em pH 6,5 ± 0,2. Foram avaliadas as segu… Show more

“…To obtain good indicators of soil quality, a combination of physical, chemical and biological attributes will occur, which together, hypothetically, would represent an ideal combination in order to provide optimal conditions for plant development and maximum expression of their biological potential (Colodel et al, 2018). In this sense, alternatives should be sought in management that are simple, economically viable and that contain technologies accessible to producers, where they seek less impact and movement in the soil structure, among them, the application to the surface of agricultural corrective products becomes a strategy to mitigate these damages to the soil (Neves Junior et al, 2013) The substantial increase in the levels of exchangeable aluminum in the soil solution can cause several morphophysiological disorders for most cultivated plants (Freitas et al, 2015), mainly affecting the root system, altering or even impeding water and nutrient absorption patterns (Pezzopane et al, 2015;Fidelis et al, 2018). These disorders also manifest deleterious effects on the aerial part of the plant body, such as reduced size and dry mass and Research, Society and Development, v. 9, n. 9, e913997981, 2020 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i9.7981 leaf deformity (Derré et al, 2013).…”
