To reach the standards of seed certification systems several quality parameters should be followed: genetic and physical purities, physiological quality and seed health. Genetic purity is the basis to reach high cultivar quality in seed production. The fundamental steps to produce soybean breeder seed are the selection of typical plants of the required cultivar, threshing each plant individually, multiplication of plant per line and line per block, and genetic analysis of each generation based on seed morphological genetic descriptors. Nowadays, application of molecular markers, originating from seed biotechnology, can be used alongside the above procedures to ensure genetic purity throughout seed production under the certification system. The use of measurements of physiological quality (germination and vigour) at several stages in seed production will be illustrated by reference to soybean seed production in Brazil. Categories of tetrazolium staining (TZ) have been developed to indicate seed vigour as well as germination. Experience in the use of TZ to monitor and maintain quality during harvesting, drying, processing, storage and delivery will be described. Seed health is assured through seed pathology tests, such as the blotter test, which, along with the results of the tetrazolium test offers a complete diagnosis of soybean seed quality, supporting the correct decision for seed treatment. High vigour, healthy and genetically pure soybean seeds produce seedlings and plants of high agronomic performance which can result in productivity increases. The considerations above lead us to understand how seed science and seed technology are closely linked and underline the importance of the scientific work within ISTA for quality evaluation in seed production.

Due to its high productivity, bovine confnement systems generate high volumes of waste that, when handled poorly, cause numerous environmental problems. One way to avoid such problems is anaerobic biodigestion, an efcient process used in manure treatment, resulting in biogas and biofertilizer as by-products. In this context, this study aimed to evaluate the efects of the application of a biofertilizer originated from the biodigestion of wastewater from dairy cattle activities to produce the forage grass Pennisetum purpureum (elephant grass?BRS Capiaçu). The experiments were carried out in an experimental feld belonging to Embrapa?Gado de Leite, located in the municipality of Coronel Pacheco, in the state of Minas Gerais, Brazil, from March to October 2018. Diferent biofertilizer doses (0, 24, 48 and 72 mm layers) were applied to the elephant grass crop and mean plant height, green and dry mass, productivity, dry matter content, lignin, neutral detergent fbers and acid detergent fbers were determined. Changes in soil fertility at the end of the second cycle after the biofertilizer application were observed. When the biofertilizer was applied at the highest dose, increased forage grass productivity and CO2 fxation were noted, although no signifcant efect on the assessed nutritional variables was observed. |
