Resumo: | The dynamics of accumulation and remobilization of NO3 -related protein content of the grains was studied in two varieties of rice, Piau? (traditional state of Maranh?o) and IAC-47 (enhanced by research institutions). The experiment was conducted in a greenhouse of UFRuralRJ in the period August 2006 to February 2007, with a completely randomized design with a factorial arrangement 2x2x4, consisting of two varieties, two levels of NO3-, 0 and 150 kg N.ha-1, and four times of collection, to 35 days after transplanting (DAT), 15 and 30 days after anthesis (DAA) and a final collection of grain and dry, with three replications, with three replicates. Each collection, the plants were cut at ground level and separated in flag leaf, leaf 2, and lower leaf sheath + stem. In each segment the fractions were analyzed nitrogen (NO3 -, NH4+ and N-amino), soluble sugars, N-total and certain activities of nitrate Redutase, P-H+-ATPase, V-H+-ATPase, H+-PPase and Glutamine Sintetase. In grains, it was determined the weight of 1000 grains, number of full and hollow grains per pot, size (Length, width and thickness) and content of N-total, crude protein and protein fractions and the relationship glutelin/crude protein. The greater capacity of accumulation and remobilization of NO3-, under conditions of lower availability of nitrogen, was given the variety Piau?, by presenting a higher content of nitrate in detriment to growth, in the initial phase of growth and increased activity of VH+-ATPases found at the beginning of the reproductive period and a lower amount of nitrogen, in both the soluble form (NO3-), as structural (N-protein and others), at the end of the cycle, using the fastest way the N after anthesis, directing it to training and filling of grains. Although the content of crude protein and protein fractions not differ among varieties, on the lowest level of N, the traditional variety, showed higher productivity. Therefore, these results indicate greater efficiency in the use of N by the variety Piau? under conditions of low availability of this nutrient. |

(tradicional do Estado do Maranh?o) e IAC-47 (melhorada por institui??es de pesquisa). O experimento foi conduzido em casa de vegeta??o da UFRuralRJ no per?odo de Agosto de 2006 a Fevereiro de 2007, com delineamento experimental inteiramente casualizado com arranjo fatorial 2x2x4, constitu?do por duas variedades, duas doses de N-NO3-, 0 e 150 Kg N.ha-1, e quatro ?pocas de coleta, aos 35 dias ap?s o transplantio (DAT), 15 e 30 dias ap?s a antese (DAA), e uma coleta final dos gr?os e da mat?ria seca, com tr?s repeti??es. A cada coleta, as plantas foram cortadas rente ao solo e separadas em folha bandeira, folha 2, folhas inferiores e bainha+colmo. Em cada segmento foram analisadas as fra??es nitrogenadas (NO3-, NH4 + e N-amino), a??cares sol?veis, N-total e determinadas as atividades das Nitrato Redutase, P-H+-ATPase, V-H+-ATPase, H+-PPase e Glutamina Sintetase. Nos gr?os, determinou-se o peso de 1000 gr?os, n?mero de gr?os cheios e chochos por vaso, dimens?es (comprimento, largura e espessura) e o conte?do de N-total, prote?na bruta e suas fra??es prot?icas e a rela??o glutelina/prote?na bruta. A maior capacidade de ac?mulo e remobiliza??o do NO3 -, sob condi??es de menor disponibilidade de nitrog?nio, foi atribu?da a variedade Piau?, por apresentar um maior teor de nitrato em detrimento ao crescimento vegetativo, na fase inicial de crescimento e maior atividade das V-H+-ATPases encontradas no in?cio do per?odo reprodutivo e uma menor quantidade de nitrog?nio, tanto na forma sol?vel (NO3-), quanto estrutural (N-prot?ico e outros), no final do ciclo, utilizando de forma mais r?pida o N ap?s a antese, direcionando-o para forma??o e enchimento dos gr?os. Embora o teor de prote?na bruta e suas fra??es prot?icas n?o diferiram entre as variedades, sob a menor dose de N, a variedade tradicional, apresentou maior produtividade. Sendo assim, estes resultados indicam maior efici?ncia no uso de N pela variedade Piau? sob condi??es de menor disponibilidade deste nutriente.Made available in DSpace on 2016-04-28T14:58:35Z (GMT).
