Resumo: | Even the element silicon being the most uptake by rice plant, many benefit effect like: increase of pest and disease tolerance, decrease of lost of water by transpiration and better the leaf architecture becoming the leafs more erect, resulting as well at the better photosynthesis efficacy. There is not too much knowledge about the uptake march in upland rice plants. This study aimed to evaluate the content of silicon in two upland rice cultivars by the influence of the application of silicate and limestone at the soil. The experiment was carried in Hapludox soil in a completely randomized experimental design in 2x2x7 factorial scheme in four replications. The treatments were consisted of calcium silicate fertilizer and limestone in interaction with seven period of physiological stage, using the upland rice cultivars Caiapó and Maravilha. At the cultivar Maravilha Si accumulation begin from tillering and achieve it better value at the microsporogenesis, while the Caiapó cultivar, occurs between tillering until the mily grain. Caiapó shows efficient Si accumulation when it was supplied to the soil. Plant organs that more accumulated silicon in both upland rice cultivars followed decreased order: stem > leaf > panicle. |

O silício é o elemento mais absorvido pela planta de arroz com diversos efeitos benéficos como: aumento da tolerância a pragas e doenças, redução da perda de água por transpiração e melhorias na arquitetura foliar tornando as folhas mais eretas, resultando também na melhoria da eficiência fotossintética. Pouco se conhece a respeito da marcha de absorção em plantas de arroz de terra altas. O trabalho teve o objetivo de avaliar o acúmulo de silício em duas cultivares de arroz de terras altas em função da aplicação de silicato e carbonato no solo. O trabalho foi realizado em casa de vegetação em Latossolo Vermelho distroférrico, utilizando delineamento inteiramente casualizado em esquema fatorial 2 x 2 x 7, com quatro repetições. Os tratamentos foram constituídos da aplicação de silicato de cálcio e calcário dolomítico em interação com sete épocas de amostragem, realizadas em diferentes estádios fenológicos; utilizando as cultivares de arroz de terras altas Caiapó e Maravilha. Na cultivar Maravilha o acúmulo de Si começa a partir do perfilhamento e alcança seu maior valor no emborrachamento, enquanto que na cultivar Caiapó, ocorre entre o perfilhamento até o estádio de grão leitoso. A cultivar Caiapó foi eficiente em acumular Si na condição em que há o seu fornecimento ao solo. Os órgãos da planta que mais acumularam silício em ambas cultivares de arroz seguiram a seguinte ordem decrescente: colmo+bainha > folhas > panícula.UEL2013-10-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1101810.5433/1679-0359.2013v34n5p2049Semina: Ciências Agrárias; Vol. 34 No. 5 (2013); 2049-2060Semina: Ciências Agrárias; v. 34 n. 5 (2013); 2049-20601679-03591676-546Xreponame:Semina.
