| Resumen: El objetivo de este estudio fue evaluar características agronómicas, rendimiento y calidad física de grano de genotipos de cebada maltera (Hordeum vulgare L.) cultivados con riego. El estudio se realizó en la región de El Bajío, México. Las variables evaluadas fueron número de macollos (NM), número de nudos del tallo principal (NN), altura de planta (AP), peso hectolítrico (PHL), peso de mil granos (PMG) y rendimiento de grano (REN).

| Durante la temporada 1999/2000, se evaluó la productividad y calidad de cebada (Hordeum vulgare L.) sembrada sola y en asociación con especies forrajeras para ensilaje. El ensayo se realizó en un suelo Ultisol en el secano de la IX Región, en el Centro Regional de Investigación Carillanca del Instituto de Investigaciones Agropecuarias (INIA), 38º41 lat. Sur, 72º25long. Oeste, 200 m.s.n.m. Los tratamientos evaluados correspondieron a cebada sembrada sola (T1) y las asociaciones de cebada/trébol rosado (Trifolium pratense) (T2), cebada/ballica (Lolium multiflorum) de rotación (T3) y cebada/pradera ballica/trébol blanco (Lolium perenne/Trifolium repens) (T4). El diseño experimental fue de bloques completos al azar, con tres repeticiones, cortando cada... |

| There is a demand for barley cultivars that are suitable for the malt industry as well as genotypes that are stable and better adapted for irrigation in the Cerrado. This study aimed to estimate the genetic parameters by assessing 69 barley genotypes from different countries, from 2012 to 2014, under irrigation in the Cerrado. Six agronomic characteristics were assessed: grain yield, plumpness kernel, thousand seeds weight, plant height, degree of plant lodging and days to heading. Analysis of variance, cluster test and phenotypic, genotypic and environmental correlations were performed. Significant effects were observed for genotypes, years and the G x E interaction. High values of broad-sense heritability (> 86%) were found for all the... |

| ABSTRACT Recently, researches have shown that the Brazilian savannah has a great potential to supply the demand for barley grains. The purpose of this study was to assess the genetic variability in 39 elite barley (Hordeum vulgare L.) genotypes based on the agro-morphological traits of a crop irrigated in the savannah system. An irrigation experiment in the design of complete randomized block with four replicates was conducted at Federal District - Brazil. The evaluated traits were: distance from the last knot to the rachis, distance from the flag leaf to rachis, spike length, number of grains by ear, flag leaf area, plant height, silking, lodging, grain yield, thousand-seed weight, protein content and grain commercial classification. After using analysis... |

| O trabalho teve como objetivos avaliar o acúmulo de matéria seca (MS) e de nitrogênio (N) da parte aérea de plantas de cevada e a taxa de sobrevivência de colmos em função da época de aplicação de N. Um experimento foi realizado em Eldorado do Sul, RS, em 2000, testando seis épocas de aplicação de N (emergência das plântulas, emissão da 3ª folha, 5ª folha, 7ª folha, 9ª folha do colmo principal (CP) e no emborrachamento) e duas doses de N (40 e 80kg ha-1). Foram determinados os acúmulos de MS e N da parte aérea no período entre o início do alongamento dos colmos e o florescimento e a taxa de sobrevivência de colmos. As aplicações de N entre a emergência das plântulas e a emissão da 9ª folha do CP resultaram nas maiores taxas de acúmulo de MS. Entretanto, as... |

| ABSTRACT The aim of this study was to investigate anatomical characteristics of barley (Hordeum vulgare L.) internodes and to reveal the connection with activity of guaiacol-peroxidases, their isoenzyme profiles, lignin, and cellulose content. Three lower internodes were sampled at elongation stage and differed in their anatomical features by showing that lignin deposition follows developmental pattern. Epidermis and hypodermis in the first internode were characterized by continuous layer of the lignified cells while in the second and third internode thin walled parenchyma cells could be observed in the hypodermis. These observations were in accordance with increment of peroxidase activity from the first to the third internode. Two acidic and 2 basic... |

| ABSTRACT High winter cereal yields depend on an adequate supply of nitrogen (N). We developed a system for indicating N rates for wheat and barley in the South-Central region of the state of Paraná, Brazil, using results of 72 field experiments conducted from 2007 to 2012. The N rates recommended for winter cereals were estimated to supply the amounts of N fertilizer needed to obtain increasing yields (<3.5, 3.5-4.5, 4.5-5.5, and >5.5 Mg ha-1) of crops grown after soybean and corn on soils with a variable organic matter content (<40, 40-60, and >60 g dm-3). The apparent mineralization rate of soil N was estimated to be 1 % and the N fertilization efficiency 50 %. The N rates recommended for wheat ranged from 30 to 150 kg ha-1 when cultivated... |

| ABSTRACT This study aimed to evaluate the performance of spray nozzles to control fusarium head blight (FHB) and mycotoxins in barley grains. The barley cultivar used in the test was ‘BRS Aliansa’, with a density of 300 plants m-2. Fungicide applications were performed using a mechanized set formed by a sprayer (Jacto, model Falcon Vortex) and a tractor (Massey Ferguson, Model 283). The spray volume used was 150 L ha-1. The nozzles used were single fan, single fan with air induction, hollow cone and double fan. The assay was performed in strips, totaling an area of 350 m2 and the variables yield and concentration of mycotoxin in the grains were determined along the strips. The data were submitted to descriptive statistics; the results were compared by F... |

| As causas da ausência e/ou baixa sobrevivência dos perfilhos foram estudadas pela conexão vascular entre os perfilhos e o resto da planta. Foram conduzidos ensaios em telado e câmara de crescimento com genótipos de trigo, IPF-49865 (unicolmo), EMBRAPA-16 e BR-23 (multicolmo), de aveia, UFRGS-10 e UFRGS-15 e de cevada, FM-519. Avaliou-se o desenvolvimento foliar do colmo principal e dos perfilhos primários, o número de perfilhos primários e secundários, o número de perfilhos férteis e a vascularização e conexão vascular dos perfilhos com o resto da planta. A conexão vascular poderia explicar a inibição dos perfilhos pois, todos estavam conectados vascularmente com o resto da planta. |
