Chemotaxis of salt-tolerant and sensitive Rhizobium strains to root exudates of lentil (Lens culinaris L.) genotypes and symbiotic N-fixation, proline content and grain yield in saline calcareous soil
Published online by Cambridge University Press: 27 March 2009
Summary
Two Rhizobium strains and five lentil genotypes were most salt-tolerant under various salt stress conditions and strain LC 6 was the most sensitive. Salt-tolerant strains were more antibiotic-resistant and showed higher relative rates of oxidation of carbohydrates and tricarboxilic acid intermediates. The content and concentrations of root exudates of lentil genotypes were different and found to be attractants for the Rhizobium strains. Under salt stress, significant interactions between salt-tolerant strains and genotypes resulted in different responses of nodulation and host plant growth measurements.
