Journal ArticleDOI
The Acetylene-Ethylene Assay for N2 Fixation: Laboratory and Field Evaluation
TL;DR: This assay was successfully applied to measurements of N(2) fixation by other symbionts and by free living soil microorganisms, and was also used to assess the effects of light and temperature on the N( 2) fixing activity of soybeans.
Journal ArticleDOI
Applications of the acetylene-ethylene assay for measurement of nitrogen fixation
TL;DR: The biochemical basis of the assay is described along with relevant characteristics including Km, C2H2/N2 conversion factor, and specific N2[C2H 2]-fixing activities obtained with various systems, and methods of measurement of N2 fixation are compared.
Book
Nitrogen Fixation in Bacteria and Higher Plants
TL;DR: The role of Diazotrophs in Global Nitrogen Economy and the relationship of ATP, Enzyme Concentration and Concentration, and Nitrogenase: The Catalysis are studied.
Journal ArticleDOI
Enhanced Mineral Uptake by Zea mays and Sorghum bicolor Roots Inoculated with Azospirillum brasilense.
TL;DR: Corn and sorghum plants grown to maturity on limiting nutrients in the greenhouse showed improved growth from inoculation approaching that of plants grown on normal nutrient concentrations.
Journal ArticleDOI
Role of Amides, Amino Acids, and Ureides in the Nutrition of Developing Soybean Seeds
TL;DR: The various nitrogenous solutes important to embryo development in symbiotic soybean plants were determined during the midpodfilling stage, and glutamine was the principal form of nitrogen, contributing 55% of the embryo nitrogen requirement.
