A produção de soja tem elevada importância no cenário nacional e do Rio Grande Sul, estando presente em parte dos estabelecimentos da agricultura familiar. O processo mercantilização intensificado a presença impérios alimentares subordinação agricultores sua lógica, promovendo concentração exclusão campo, resultando na diferenciação agricultores. estudo, caráter longitudinal, por objetivo anali...

Soybean (Glycine soja var Beeson) formate dehydrogenase has been isolated, purified, and partially characterized by affinity chromatography. The enzyme is a dimer having a total molecular weight of 100,000 and a subunit weight of 47,000. It has activity over a broad pH range, is stable for months at 4 degrees C, and has K(m) values of 0.6 millimolar and 5.7 micromolar for formate and NAD, respe...

Poder calorífico de misturas de biodiesel dos ésteres metílicos de colza (RME) e soja (SME) foram determinados usando um calorímetro de combustão de alta precisão. A dependência dos valores calóricos com a temperatura e pressão no intervalo (273-373) K e (1 a 200) bar foram derivados para misturas de RME e SME de biodiesel B100. Foram propostas equações práticas para o cálculo da correção da te...

Knowledge of the spatial patterns of genetic variation in wild populations has significant implications for in situ conservation and the determination of conservation order. To study the levels of genetic diversity, spatial genetic structures, and genetic distances in Glycine soja, 11 natural populations in northern China were analyzed by estimating genetic coefficients using inter-simple seque...

The objective of this work was to evaluate the genetic variation of trypsin inhibitor in cultivated (Glycine max L.) and wild (Glycine soja Siebold & Zucc.) soybean varieties. Genetic variations of the Kunitz trypsin inhibitor, represented by a 21‐kD protein (KTI), and of the Bowman‐Birk trypsin–chymotrypsin inhibitor (BBI) were evaluated in cultivated (G. max) and wild (G. soja) soybean variet...

Tolerant soybean (Glycine max [L.] Merr.) cultivars aid in reducing salt damage in problem fields. New genes are important to reduce losses from salt injury. Objectives of this study were to determine inheritance of salt tolerance in wild soybean (Glycine soja Sieb. and Zucc.) PI483463 and to test allelism of tolerance genes from genotypes PI483463 and S-100, a common ancestor of southern in US...

Soybean [Glycine max (L.) Merr.] is an important crop rich in vegetable protein and oil, and is a staple food for human and animals worldwide. However, soybean plants have been challenged by soybean cyst nematode (SCN, Heterodera glycines), one of the most damaging pests found in soybean fields. Applying SCN-resistant cultivars is the most efficient and environmentally friendly strategy to mana...

Resumo Introdução A dessecação de pré-colheita tornou-se comum no cultivo soja, principalmente pela necessidade antecipação da colheita para grãos ou sementes. Contudo, existem poucos herbicidas registrados esta prática, podendo ainda apresentar efeitos distintos conforme a região cultura. Objetivo Diante disto, este trabalho teve o objetivo avaliar os nas características agronômicas e na quali...
