This work was carried out at the Fazenda Experimental Lageado, at Botucatu, SP, to evaluate the physiological quality of cucumber (Cucumis sativus L.), seeds harvested at different fruit maturity stages and post-harvest resting periods. Fruits of cultivar Pérola were harvested at 6 ages (20, 25, 30, 35, 40 and 45 days after anthesis) and they were stored at room temperature for 0, 5, 10 or 15 days before seed extraction. After this, seeds were fermented for 2 days, washed and dried. External visual characteristics of fruits and seeds were observed at harvest. Seed quality was evaluated as for moisture, dry matter content, dimensions, germination, and vigour. Results showed that seed germination and vigour increased in fruits aging from 20 to 40 days. Post-harvest periods improved seed quality of 20-day old fruits not reaching the seed quality levels observed in 40 or 45-day old fruits, without post-harvest resting period. Seeds from fruits at 25, 30 and 35 days of age, with 10 or 15 days of post-harvest resting period reached the same quality levels of seeds from fruits with 40-45 days old.

The objective of this work was to evaluate the agronomic performance and grain quality, especially the grain technological characteristics in the common bean genotypes, cultivated in winter-spring season. The experiment was carried out in Jaboticabal-SP, in a Rhodic Hapludox. The experimental design was a randomized block with 17 treatments (genotypes) with three replications. The plots had been composed for 17 carioca common bean group genotypes (Pérola, BRS Cometa, BRS Pontal, IPR Juriti, CNFC 10703, CNFC 10713, CNFC 10716, CNFC 10721, CNFC 10729, CNFC 10733, CNFC 10742, CNFC 10753, CNFC 10757, CNFC 10758, CNFC 10762, CNFC 10763 and CNFC 10813). BRS Pontal and CNFC 10716 showed simultaneously the higher number of per plant and grain yield. The technological characteristics more expressive was verified in CNFC 10703, CNFC 10713, CNFC 10758, CNFC 10813 and CNFC 10716 genotypes, principally about the protein content, cooking time and grain hydration capacity. The CNFC 10716 genotype detached as promissory, because their elevated agronomic performance and satisfactory technological characteristics.
