Summary
Nitrate assimilation in the first trifoliate leaf of vegetative soybean plants (Glycine max L. Merr, cv Hodgson) was studied in relation to nodulation. Nodulated and non-nodulated plants were grown in a nitrate medium (4mM). As a control nodulated plants were grown in a nutrient medium without combined nitrogen. This study included measurements of the acetylene reduction activity of the whole plant and of the in vitro nitrate reductase, glutamine synthetase and glutamate dehydrogenase activities in the first leaf and of the nitrate concentration. Nitrate accumulation and nitrate reductase activity were depressed in nodulated plants; root growth was decreased in the presence of nitrate. The relationships between nitrate assimilation and nodulation are discussed.
