MATERIALS AND METHODS Sulfate translocation in soybean (Glycine max L. Merr) was investigated. More than 90% of the sulfate entering the shoot system was recoverable in one or two developing trifoliate leaves. In young plants, the first trifoliate leaf contained between 10 to 20 times as much sulfate as the primary leaves, even though both types of leaf had similar rates of transpiration and ph...

In soybean (Glycine max [L.] Merr.), maintaining favorable growth conditions (e.g., water, solar radiation, and nutrients) during the seed filling period is crucial to avoid limitations that could reduce weight ultimately constrain yield. The objective of this study was explore potential effects identify if “late-season” management practices can contribute increasing yield in soybeans.

Salinity stress restricts growth of soybean plant [Glycine max (L.) Merr.]. Glycine betaine (GB) is among osmoprotectant compounds that are produced in tolerant plant species in response to environmental stresses. Soybean is sensitive to soil salinity and is classified as a low-ccumulator of glycine betaine. Therefore, this study was performed to evaluate the salinity tolerance of two contrasti...

Soybean (Glycine max [L.] Merr.) is a major crop species and, therefore, a major target of genomic and genetic research. However, in contrast to other plant species, relatively few chromosomal aberrations have been identified and characterized in soybean. This is due in part to the difficulty of cytogenetic analysis of its small, morphologically homogeneous chromosomes. The recent development o...
