Ácidos orgânicos na solução de um gleissolo sob diferentes sistemas de cultivo com arroz irrigado

Abstract: RESUMOO alagamento do solo para o cultivo do arroz irrigado promove condições anaeróbias que favorecem a produção de ácidos orgânicos de cadeia curta, os quais podem ser tóxicos para a cultura. Entretanto, a quantidade produzida destes ácidos depende, dentre outros fatores, do sistema de manejo empregado para o cultivo do arroz. Para avaliar a formação de ácidos orgânicos durante o cultivo do arroz irrigado nos sistemas: convencional, semeadura direta e pré-germinado sobre resíduos de azevém, foram instalados … Show more

“…Among the short-chain aliphatic acids formed, acetic and butyric acids are those found in higher concentrations, wherein the acetic acid is present at higher concentrations than butyric acid, ca. 10x (Bohnen et al, 2005).…”

“…Os principais produtos fi totóxicos produzidos são os ácidos orgânicos alifáticos de baixo peso molecular (acético, propiônico e butírico), que ocorrem na faixa de concentração de 0,1 a 16mM (ANGELES et al, 2005) e relação de 6:3:1, respectivamente (BOHNEN et al, 2005), os quais atingem valor máximo poucos dias após o alagamento, podendo ocorrer toxidez às plantas (SOUSA & BORTOLON, 2006).…”

“…Among the toxic substances produced, the organic acids of short-chain such as acetic, propionic and butyric acids stand out, and depending on the amount produced they can exert negative effect on rice plants (Sousa, 2001). Acetic acid has been found in higher concentrations in the soil, followed by propionic and butyric acids (Bohnen et al, 2005).Organic acid toxicity appears in the early stages of rice development, causing reduction in germination (Neves et al, 2006), root growth, weight and height of seedlings (Sousa & Bortolon, 2002).…”
