• Abstract

  Seed testing is an important component of seed production systems. It is a dynamic activity as shown by the improvement of the available procedures and the development of new approaches and modem methodology. These tools comprise relatively new techniques such as seed and seedling imaging analysis that have indicated consistent potential to be used in basic and applied research. This prop…

• Abstract

  Maize crop (Zea mays L.), when compared to others, has much more possibility of producing seeds with high physiological potential, given its morphological and chemical constitution and the advent of hybrid maize. In addition, harvesting and drying are key steps in preserving the quality of seed. Several changes may occur in seeds during desiccation, such as changes in membrane lipids comp…

• Abstract

  The occurrence of soybean diseases is considered one of the causes of the reduction of grain yield. Besides affecting productivity, the disease can also cause damage to seed quality. Soybean seeds are an important vehicle for the dissemination and survival of many pathogens, which can interfere with germination and vigor. For this reason, shows the importance of using healthy seeds and vi…

• Abstract

  The corn (Zea mays L.) crop, when compared to other crops, has a much greater possibility of producing seeds with high physiological potential given its morphological and chemical constitution and the advent of hybrid corn. However, to guarantee that hybrid seeds have high quality it is essential to use compatible parental lineages. In corn seeds, physiological potential problems are usua…

• Abstract

  The main challenge of studies on seed vigor is the identification of parameters related to seed deterioration, which precede loss of germination capacity. The protein electrophoresis technique may enable the detection of the deterioration initial stages by the evaluation of enzyme activities associated with degradation and oxidation processes of reserve substances as well as with biosynth…
