| Abstract | We analyzed the effects of NaCl stress on nine lines of Medicago truncatula, including four lines from southern Tunisia, three from the north, and two references lines. Plants were cultivated in two treatments (0 and 45 mM NaCl) for a period of 45 days. At harvest, we measured seven quantitative traits of the shoot and root growth. The analysis of variance showed that responses of lines to NaCl stress depended on the effects of line, treatment, and their interaction. Treatment had the largest effect. All measured traits showed high broad-sense heritability (H $^{2}$) under both treatments. While the leaf area was the less affected trait, the length of stems was the most affected regarding the sensitivity index (SI) parameter. Estimated SI for total plant biomass showed that TN13.11 and TN11.0 were the most contrasting lines with the lowest and the highest values, respectively. Established correlations between measured traits and the hierarchical cluster relationships among lines depended on the treatment effect. The site-of-origin environmental factor that influenced more the response of lines to NaCl stress was the relative humidity. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
