| RESUMOO trigo na colheita está exposto a danos por chuva, que podem levar à alteração na qualidade e perda de valor comercial. O objetivo desse trabalho foi caracterizar as alterações de diferentes variedades de trigo da região Sul que sofreram danos por chuva, detectado pelo método de falling number. Treze amostras foram avaliadas quanto a peso hectolitro, peso de mil sementes, proteína, açúcares redutores, nitrogênio solúvel, nitrogênio de aminoácidos livres e atividade enzimática α e β-amilase, β-glucanase e protease). As alterações na fração de gliadina foram avaliadas por eletroforese SDS-PAGE. As variáveis açúcares redutores, nitrogênio solúvel, nitrogênio de aminoácidos livres, atividade de α-amilase, β-glucanase e protease apresentaram correlações... |

| Sprouting or germination in wheat takes place as a result of the rupture of the dormancy in grain, expressed in physiological terms as the increase of α-amylases and proteases activity, which has been associated with low values of falling number. Grain sprouting has been related with high moisture and temperature at harvest and it is a serious problem in the north of Argentina. The objectives of this study were to characterize introduced and local wheat cultivars for sprouting response through falling number and, tentatively, to identify adapted materials with good behavior for this trait. A set of thirty introduced and local late and early heading wheat varieties was tested through falling number in two experiments conducted at Marcos Juárez,... |

| Abstract:The objective of this work was to characterize the performance of elite wheat genotypes from different Brazilian breeding programs for traits associated with grain yield and preharvest sprouting. The study was conducted in 2010 and 2011 in the municipality of Capão do Leão, in the state of Rio Grande do Sul, Brazil, in a randomized complete block design with three replicates. Thirty-three wheat genotypes were evaluated for traits related to preharvest sprouting and grain yield. The estimate of genetic distance was used to predict potential combinations for selection of plants with high grain yield and tolerance to preharvest sprouting. The combined analysis of sprouted grains and falling number shows that the TBIO Alvorada, TBIO Mestre, Frontana,... |

| The change in quality of wheat grains in terms of physical parameters (moisture, test weight, 1000 grain weight and insect damage), chemical parameters (protein, fat, ash and starch) and flour quality tests (falling number, water absorption, dough development time and dough stability) were observed during storage in conventional structures (earthen bin, metal bin, bulk covered and room store) for 12 months. The results showed that test-weight (66.8 kg/hl), 1000 grain weight (39.67 g), protein (8.9%), fat (1.82%), ash (1.62%), starch (61.64%), falling number (285 s), water absorption (62.54%), dough development time (4.7 min) and dough stability (7.47 min) were recorded highest in grain samples collected from earthen bin followed by metal bin, bulk covered... |
