“…Rotundo et al (2016) determined that the spatial variation occurs at scales lower than politically defined regional and state lines. Many underlying weather and environmental factors have been suggested to explain this variation, including differences in temperature throughout the growing season (Gibson and Mullen, 1996;Howell and Cartter, 1958;Thomas et al, 2003;Wilson, 2004;Wolf et al, 1982;Yaklich and Vinyard, 2004). The effect of temperature, specifically during seed fill, has been heavily credited with altering seed composition and was found to be consistent across six varieties in a Kentucky study (Kane et al, 1997).…”

Core Ideas Planting date and maturity group decisions can greatly affect yield and composition. Temperature had a significant effect on seed yield and composition. Planting date × maturity group should be chosen based on the product's end use. Soybean [Glycine max (L.) Merr.] production has greatly increased in the upper U.S. Midwest over the last decade, but little information exists regarding the interactive effects of environment and spring management decisions on soybean seed yield and composition. Our objective was to assess the effect of four planting dates (PDs), four cultivar maturity groups (MGs), and ambient temperature between R5 to R8 (T5–T8) on soybean seed yield and composition. Field studies were established between 2014 and 2016 at three locations in Wisconsin and one in Minnesota. Across environmental conditions and management decisions, greater seed yield was positively correlated with protein and oil contents but negatively correlated with linoleic, linolenic, and sucrose contents. Multivariate data analysis showed positive synergies between early planting (late April–early May) and MG 2 for yield, oil, and oleic acid across the examined region. A MG 2 was the highest yielding and a ∼1200 kg ha−1 yield difference was observed between early and late PDs. These results underline the complexity of the soybean yield‐composition relationships. Additionally, the large variability in the responses of constituents to management decisions and temperature variations highlights the importance of a producer knowing the product's end use (e.g., high yield vs. high protein) and accordingly modifying the growing environment by selecting an appropriate PD and MG for the respective region. To provide more accurate recommendations to a broader range of producers, multi‐environment studies are imperative to capture large environmental variability in important soybean production areas across the United States.

“…A correlação inversa entre óleo e proteína nas sementes de soja foi estudada por vários autores (HYMOWITZ et al, 1972;HOWELL;CARTTER, 1953;FARACO et al, 1981) O trabalho foi conduzido no laboratório de Fitotecnia da Universidade Estadual de Londrina, Paraná. As cultivares utilizadas foram a BRS 184 (FT Guaíra x IAC 13 c), grupo de maturação (GM) 6.7, de ciclo semiprecoce com 24,2% de óleo e a BRS 282 (Embrapa 48 x BR94-23316), grupo de maturação (GM) 6.9, de ciclo semiprecoce com 18,6% de óleo (EMBRAPA, 2011).…”

Acúmulo de óleo em sementes de soja cultivadas in vitro e in vivo

A semente de soja apresenta, cerca de 20% da sua massa seca em óleo e 40% em proteína. Esse teor de óleo pode sofrer influência perante as condições ambientais durante o enchimento das sementes, produzindo modificações na sua composição bioquímica. Em condições de cultivo in vivo é difícil controlar esse fator. Nesse sentido, o cultivo in vitro vem auxiliar a pesquisa, pois a semente fica isolada da planta mãe em ambiente controlado. O objetivo deste trabalho foi avaliar os teores de óleo das cultivares BRS 184 e BRS 282 cultivadas in vitro e in vivo. O cultivo in vivo ocorreu em casa de vegetação em vasos com a coleta de sementes no estádio R8, e o cultivo in vitro, em laboratório, utilizando sementes imaturas removidas da planta mãe no estádio R5 e cultivadas em meio de cultura líquido contendo 20 mM, 40 mM e 60 mM de glutamina, e concentração de sacarose de 204,5 mM, com agitação constante por oito dias à temperatura de 25 ± 0,2 ºC. Decorrido o tempo para o cultivo in vitro foi avaliado o ganho de massa de matéria fresca das sementes, e após, em ambos os experimentos, foi determinado o teor de óleo para o cultivo em R5, e para R8. O acúmulo de óleo nas sementes de soja apresenta interações complexas, variando entre genótipo e condições ambientais tanto no cultivo in vivo quanto in vitro. Há correlação positiva entre ganho de massa e teor de óleo nas sementes.

“…Piper and Boote (6) evaluated regression models of oil concentrations vs. temperature and found that oil concentration increased with temperature and approached a maximum at a mean of 28°C. Others (7,11) have shown that increased temperature increases the oil concentration of the seed. However, none of the methods in these publications attempted to use monthly weather variables to classify a set of oil concentration data.…”

Temperature and precipitation variables during linear seed fill are known to be environmental determinants of protein and oil composition of the soybean [Glycine max (L.) Merr.] seed. However, the contribution of other precipitation and temperature events during the growing season and a method that would determine the precipitation and temperature variables most related to protein and oil concentration values of the seed has not been fully explored. The former was evaluated by comparing monthly temperature and precipitation variables of the growing seasons to protein and oil data for the years 1959 to 1996 from three locations listed in the Uniform Soybean Tests, Northern Region. The data set comprised locations from Maturity Groups II and III and consisted of 186 location‐years. Classification and regression “tree‐based” analysis were conducted to determine the month, environmental variable, and “splitting” points that correctly classified most of the 186 location‐years for below‐vs.‐above‐median protein or oil composition. The protein concentrations from the location‐years were separated into these two median‐boundary categories most readily by temperature variables from the months of April and August. The oil concentrations from the location‐years were classified best by August and September temperature variables and precipitation in May and September. The sum of protein and oil concentrations from the location‐years were best separated by August and July temperature variables and precipitation in May and July. The protein‐to‐oil ratios from the location‐years were best separated by September precipitation and July and June temperature variables. These data demonstrate that tree‐based models can use monthly temperature and precipitation variables during linear seed fill and other specific months of the crop year and relate them to the final protein and oil concentration in the seed. These results could be used by the processing industry to estimate seed composition before harvest.
