| Abstract | Seedlings of Chinese pine (Pinus tabulaeformis Carr.) were grown in a growth chamber using a sterilized soil/sand/vermiculite mixture, and were inoculated with the ectomycorrhizal fungus Cenococcum graniforme (Sow.) Ferd. and Winge. The function of external mycelium of ectomycorrhiza for uptake and transport of N from 15N-labeled NH4 + and NO3 – for plant nutrition was evaluated under well-watered conditions and water stress. The pots comprised two-compartments, whereby the penetration of roots was prevented by a nylon mesh bag which the mycorrhizal hyphae were allowed to pass in order to colonize the rest of the pot. 15N-labeled NH4 + or NO3 – was applied to the area of the pot to which the root had no access. At harvest, the 15NH4 + concentration in plant tissues was significantly promoted by the formation of mycorrhizae both under well-watered conditions and water stress. The 15NO3 – concentration was reduced by water stress and increased by mycorrhizal formation. The enhancement of 15NO3 – uptake caused by mycorrhizal formation was more evident under water stress than under well-watered conditions. The external mycelia of the ectomycorrhizae took up and transported NH4 + and NO3 – from the soil to the plant, thereby improving plant nutrition and growth, in addition to helping the plants to avoid the effects of water stress. |

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.
