| Abstract | Preconditioning by hypoxic condition would contribute higher tolerance to anoxic condition in physiological and metabolic aspects of various plant species. In expectation of improvement of salinity tolerance, effects of preconditioning with soil flooding on growth responses and photosynthetic activity in relation to Na$^{+}$ content in leaves and roots were studied using 2-year-old Taxodium distichum saplings. A submergence experiment was performed at three salt concentrations (0, 4000, and 8000 ppm NaCl), and preconditioning was started 2 months prior to the beginning of submergence treatments. Continuous soil flooding with freshwater as a control did not inhibit growth in height and stimulated diameter increment of the saplings. Saplings submerged in saltwater and freshwater also showed no morphological changes during submergence treatments. However, leaf injury and shoot dieback were observed in drained saplings that had been submerged in saltwater. Na$^{+}$ and K$^{+}$ ion contents increased with increases in salt concentration in both preconditioned and unconditioned saplings, whereas ion contents in preconditioned saplings tended to be higher than those of unconditioned saplings. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
