RESUMO - Sementes de feijoeiro (Phaseolus vulgaris L.), cv. Aroana e Carioca, foram submetidas a classificação pelo tamanho, utilizando-se uma serie de peneiras manuais com crivos oblongos. Em seguida, cada fração foi armazenada, sob condições normais de ambiente, e submetida a testes periódicos de germinação e de vigor (primeira contagem, velocidade de germinação e envelhecimento acelerado) durante seis meses, conduziu-se, também, um ensaio de campo durante a época "das águas". Concluindo-se que a classificação das sementes por diferenças de espessura corresponde a uma separação de níveis de qualidade fisiológica; no entanto, a decisão final quanto a classificação depende da proporção com que as sementes menores participam do lote. ABSTRACT - The effects of bean seed size on germination, vigor and yield of bean plant (Phaseolus vulgaris L.) cv. Aroana and Carioca were studied under laboratory and field conditions. The seeds were sized into classes differing by 0.4 mm in thickness. Physiological quality of seeds from size classes was evaluated using standard germination and vigor tests (first counting, speed of germination and accelerated aging test), during six months. The results showed that seed of the rnean and larger size classes were better in physiological quality than those of smallest classes. |

Abstract Laboratory and greenhouse studies were conducted with the Neotropical brown stink bug, Euschistus heros (F.), to evaluate and compare adult damage at two infestation levels (2 and 4 adults/plant) and feeding behavior on seeds of three resistant soybean cultivars bearing the Block technology (?BRS 1003 IPRO?, ?BRS 543 RR?, and ?BRS 391?) compared to a susceptible cultivar (?BRS 5601 RR?). No difference in number or weight of damaged seeds (as percentages) was found among the cultivars at either infestation level. Differences were only observed between infestation levels within cultivar; higher values were reported with 4 adults/plant, except for ?BRS 543 RR?. At 2 adults/plant, total seed area damaged (mm2) and percentage of seed area damaged were signifcantly lower only on ?BRS 1003 IPRO?; signifcant differences among cultivars were found in damage to internal but not external seed surfaces. At 4 adults/plant, all Block cultivars differed from ?BRS 5601 RR? in overall seed damage, and greater percent damage occurred on both seed surfaces on ?BRS 5601 RR?. Electropenetrography (EPG) demonstrated that adults reached and fed in the seeds of all soybean cultivars. However, the feeding event duration in seeds of Block cultivars was much shorter than on ?BRS 5601 RR?, which likely explains differences between internal and external seed damage. Furthermore, the total duration of feeding activities on seeds of Block cultivars was ca. 4?6 times shorter than on the susceptible cultivar; these two EPG feeding variables account for the lower seed damage observed for the Block cultivars. These cultivars represent an important new strategy for pest control on soybean.
