Factors Affecting Tocopherol Concentrations in Soybean Seeds
(American Chemical Society, 2016-10-31)Soybean seeds contain several health-beneficial compounds, including tocopherols, which are used by the nutraceutical and functional food industries. Soybean tocopherol concentrations are, however, highly variable. Large ... -
Fast classification system for drought tolerance in peanut and soybean
(Sociedade Brasileira de Fisiologia Vegetal (SBFV), 2022-09-06)Drought is one of the major limitations for agriculture. The direct selection of tolerant genotypes on the fields is time consuming due to the unpredictability of the environmental conditions. Our group use a physiological ... -
