RESUMO: A utilização de sementes de alta qualidade é indispensável para o sucesso da produção agrícola. Assim, o objetivo deste trabalho foi avaliar o efeito da inoculação com Azospirillum brasilense e doses de adubação nitrogenada em cobertura na qualidade fisiológica e sanitária de sementes de trigo. Foram avaliadas separadamente sementes das cultivares BRS 220 e BRS Tangará, cultivadas com e sem inoculação de Azospirillum e cinco doses de nitrogênio em cobertura (0, 30, 60, 90 e 120 kg ha?1). Posteriormente, foi instalado o experimento de laboratório, em delineamento inteiramente causalizado em esquema fatorial 2 x 5 (com e sem inoculante × doses), com quatro repetições. Além da qualidade sanitária, determinada pelo método de papel filtro, foi avaliada a qualidade fisiológica das sementes pelos testes de germinação, envelhecimento acelerado, frio, condutividade elétrica, emergência de plântulas em areia, comprimento e massa seca de parte aérea e raiz. Os dados foram submetidos à análise de variância, com comparação de médias para inoculação e regressão para doses de nitrogênio. A qualidade sanitária das sementes de trigo não é influenciada pelas doses de nitrogênio e a inoculação com Azospirillum brasilense. A inoculação das sementes de trigo com Azospirillum brasilense favorece o vigor (envelhecimento acelerado) para a cultivar BRS 220 e massa de parte aérea de plântulas para a BRS Tangará. As cultivares apresentam respostas diferenciadas à adubação nitrogenada para as características de qualidade de sementes. O aumento nas doses de nitrogênio até 120 kg ha?1 melhora a qualidade fisiológica das sementes da cultivar BRS Tangará. ABSTRACT: The use of high quality seeds is essential for successful agricultural production. The aim of this study was to evaluate the effect of inoculation with Azospirillum brasilense and nitrogen fertilization on the physiological and sanitary quality of wheat seeds. Seeds of BRS 220 and BRS Tangará cultivars were evaluated separately, grown with and without inoculation of Azospirillum brasilense and five levels of nitrogen (0, 30, 60, 90 and 120 kg ha?1). Subsequently, a laboratory experiment was conducted in a completely randomized design with factorial arrangement of 2 x 5 (with and without inoculation x doses) and four replications. Besides the sanitary quality, determined by the blotter spot test, seed physiological quality was evaluated by the following tests: germination, accelerated aging, cold, electrical conductivity, seedling emergence in sand, and length and dry mass of shoots and roots. Data were submitted to analysis of variance with comparison of means for inoculation and regression for nitrogen doses. Sanitary quality was not influenced by nitrogen application and inoculation with Azospirillum. The inoculation of wheat seeds with Azospirillum brasilense favors increase in vigor (accelerated aging) for BRS 220 cultivar and seedling shoot mass for BRS Tangará cultivar. The cultivars presented differentiated responses to nitrogen fertilization regarding seed quality. The increase in doses up to 120 kg N ha?1 improves the physiological quality of BRS Tangará cultivar seeds.

The coffee leaf-miner (CLM) (Leucoptera coffeella Guérin-Mèneville; Lepidoptera: Lyonetiidae), the main pest of coffee plants, occurs widely throughout the Neotropics where it has a significant, negative economic and quantitative impact on coffee production. This study was conducted in a rubber tree/coffee plant interface that was influenced by the trees to a varying degrees depending on the location of the coffee plants, i.e. from beneath the rubber trees, extending through a range of distances from the edge of the tree plantation to end in a coffee monocrop field. The most severe damage inflicted on coffee plants by the CLM (number of mined leaves) from April, which marks the start of the water deficit period, until September 2003 was in the zone close to the rubber trees, whereas the damage inflicted on plants in the monocropped field was comparable to that on coffee plants grown directly beneath the rubber trees, which received about 25-40 % of the available irradiance (Ir-available irradiation at a certain position divided by the irradiation received in full sunlight, i.e. in the monocrop). From May until July damage caused by the CLM nearly doubled in each month. In midwinter (July), the damage decreased perceptibly from the tree edge toward the open field. From September onward, with the rising air temperatures CLM damage in the coffee monocrop started to increase. Based on these results, we conclude that coffee plants grown in the full sun incurred the most damage only at the end of winter, with warming air temperatures. Coffee plants grown in shadier locations (25-40 % Ir) were less damaged by the CLM, although a higher proportion of their leaves were mined. The rubber trees probably acted as a shelter during the cold autumn and winter seasons, leading to greater CLM damage over a distance outside the rubber tree plantation that was about equal to the height of the trees. Future studies should attempt to relate leaf hydric potential to pest attack in field conditions. More rigorous measurements of shade conditions could improve our understanding of the relationship of this factor to CLM attack.
