Seventeen were selected. DNA extracted polymerase chain reaction amplifications...

The aimed to correlate the micronutrients content in soybean seeds with their physiological potential. work was developed Federal University of Pelotas, facilities Seed Science and Technology Graduate Program. experimental design randomized blocks arranged four replicates. measured were: B, Cu, Fe, Mn, Mo, Zn, Al Na. magnitudes are dependent on genetic constitutions cultivars. Higher variations expressed for boron, copper, manganese, zinc, molybdenum, sodium aluminum content, while iron is...

The objective of this research is to define which soybean phenological stage adequate promote pre-harvest desiccation and measure the effects procedure on physical physiological attributes seeds throughout storage. experiment was carried out at Fazenda Santa Bárbara da Boa Vista located in municipality Cabeceiras, Goiás, Brazil. experimental design randomized blocks arranged a factorial scheme being five stages development where desiccant applied (R5.5, R6.0, R7.1, R7.3 R8.3) × post-harvest...

Rice (Oryza sativa L.) presents a strategic role in social and economic levels. The aim of this study was to elucidate the presence genetic variability for genus Oryza, possibility using genotypes with wild characteristics rice breeding programs.
