Effect of Nitrate on Nodulation and Nitrogen Fixation of Soybean
1.1 Biological nitrogen fixation and nitrogen nutrition in soybean plants Biological nitrogen fixation is one of the most important processes for ecosystem to access available N for all living organisms. Although N2 consists 78% of atmosphere, but the triple bond between two N atoms is very stable, and only a few group of prokaryotes can fix N2 to ammonia by the enzyme nitrogenase. Annual rate ...
متن کاملInhibition of N2 fixation in soybean is associated with elevated ureides and amino acids.
Decreased N2 fixation in soybean (Glycine max) L. Merr. during water deficits has been associated with increases in ureides and free amino acids in plant tissues, indicating a potential feedback inhibition by these compounds in response to drought. We evaluated concentrations of ureides and amino acids in leaf and nodule tissue and the concurrent change in N2 fixation in response to exogenous u...

متن کاملEffects of Solar Radiation Regimes on Growth and N2 Fixation of Soybean, Cowpea, and Bushbean
Legumes are commonly grown in the tropics under reduced solar radiation due to dense cloud cover and shading from plantation or tall intercrops. This paper examines the growth and N2 fixation of several grain legumes common to the tropics on an Oxic Haplustoll in Hawaii. Plantings were made in April (warm season) and November (cool season) of soybean (Glycine max L. Merr.) ‘Kahala’; Cowpea (Vig...
متن کاملSoybean N2 Fixation Estimates, Ureide Concentration, and Yield Responses to Drought
al., 1998) experiments have shown that N2 fixation in soybean is especially sensitive to water deficits and deIncreasing N2 fixation tolerance to drought has been hindered by creases before transpiration or photosynthesis. Furtherthe labor and costs of quantifying N2 fixation using 15N methodologies. The relative abundance of ureides (RAU) in plant tissues has been more, soybean grain yield und...
