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 کاملInvolvement of ureides in nitrogen fixation inhibition in soybean
The sensitivity of N2 fixation to drought stress in soybean (Glycine max Merr.) has been shown to be associated with high ureide accumulation in the shoots, which has led to the hypothesis that N2 fixation during drought is decreased by a feedback mechanism. The ureide feedback hypothesis was tested directly by measuring the effect of 10 mM ureide applied by stem infusion or in the nutrient sol...
متن کاملEffects of Meloidogyne incognita on Nitrogen Fixation in Soybean.
The effects of a North Carolina population of Meloidogyne incognita on N fixation on root-knot-susceptible 'Lee 68' and moderately resistant 'Forrest' soybean were evaluated 50, 75, I00, and 135 days after inoculation with nematodes. Nematodes stimulated N fixation in Lee 68 by 50 days and in Forrest by 75 days. At all other intervals, N fixation was either depressed or unaffected by nematodes....
متن کاملWithin-Leaf Nitrogen Allocation in Adaptation to Low Nitrogen Supply in Maize during Grain-Filling Stage
Nitrogen (N) plays a vital role in photosynthesis and crop productivity. Maize plants may be able to increase physiological N utilization efficiency (NUtE) under low-N stress by increasing photosynthetic rate (P n) per unit leaf N, that is, photosynthetic N-use efficiency (PNUE). In this study, we analyzed the relationship between PNUE and N allocation in maize ear-leaves during the grain-filli...
متن کاملA study on evaluation of nitrogen fixation potential in soybean cultivar using commercial and indigenous strains
Earthen pots experiments were conducted for the evaluation of nitrogen fixing potential of three indigenous Bradyrhizobium japonicum isolates and one commercial inoculum (Narmada biofertilizer) in three commonly grown soybean cultivars viz., JS-335, JS-9305 and JS-7322. Nitrogen fixation was assessed in terms of root nodules number, root and shoot length and their dry weight. Results indicate t...
