Comparative study of nitrogen fixation and carbon metabolism in two chick-pea (Cicer arietinum L.) cultivars under salt stress
salinity is one of the major environmental constraints on agriculture in many regions of the world (Boyer, 1982; Two cultivars of Cicer arietinum with differential tolerSerrano and Gaxiola, 1994). Chick-pea (Cicer arietinum ance to salinity have been compared by analysing L.) nodules are indeterminate (Hirsch, 1992) and export growth, photosynthesis, nodulation, nitrogenase activfixed N as amid...
متن کاملCarbon metabolism and bacteroid respiration in nodules of chick-pea (Cicer arietinum L.) plants grown under saline conditions
The present work investigates the relationships between nitrogen fixation, carbon metabolism and oxygen consumption by bacteroids of Mesorhizobium ciceriin root nodules of chick-pea plants. Its aim was to establish whether some of the compounds which accumulate under salt stress may be used as respiratory substrates by bacteroids to fuel their own metabolism and nitrogenase activity. Plants wer...
متن کاملThe effects of salinity and sodicity upon nodulation and nitrogen fixation in chickpea (Cicer arietinum).
Production of grain legumes is severely reduced in salt-affected soils because their ability to form and maintain nitrogen-fixing nodules is impaired by both salinity and sodicity (alkalinity). Genotypes of chickpea, Cicer arietinum, with high nodulation capacity under stress were identified by field screening in a sodic soil in India and subsequently evaluated quantitatively for nitrogen fixat...

Research Article Stability analysis for grain yield and yield components in chick pea (Cicer arietinum l.) Abstract: Twenty one advanced breeding lines selected from All India Coordinated trials and one local popular variety " annegiri' were studied over three years to identify high yielding stable genotypes. Genotype , environment and G x E interaction variance found to be significant. Genotyp...
متن کاملChanges in the Nodular Metabolism in Desi and Kabuli Genotypes of Chickpea (cicer Arietinum L.) under Salt Stress
Experiments were conducted to study the nodular metabolism, in order to draw comparisons between nitrogen fixation, carbon fixation and ammonia assimilation in nodule cytosol of desi (CSG 8962, DCP 92-3) and kabuli (CSG 9651, BG 267) genotypes of chickpea. Maximum acetylene reduction activity (ARA) was observed in CSG 9651 and minimum in DCP 92-3.The specific activity of ammonia assimilating en...
