| Abstract | A method for efficient in vitro regeneration of Leucaena leucocephala cv. K636 was developed using immature zygotic embryos as the explant. Multiple shoot induction was achieved by culturing the explants on half-strength Murashige and Skoog (MS) medium supplemented with thidiazuron (TDZ) (0.03 to 1.5 μM). The maximum number of shoots per explants was achieved in 0.26 μM TDZ-supplemented media. TDZ concentration significantly influenced the induction of multiple shoots as well as the shoot-length. TDZ at 0.35 μM or higher concentrations resulted in abnormal stunted shoots. Full-strength MS media devoid of any plant growth regulator were used for shoot elongation. In vitro root induction was achieved in half-strength MS media supplemented either with 0.54 μM 1-naphthaleneacetic acid (NAA) or with 14.76 μM indole-3-butyric acid (IBA) in combination with 0.23 μM kinetin (Kn). Media supplemented with 14.76 μM IBA in combination with 0.23 μM Kn induced twofold–threefold more roots than media supplemented with 0.54 μM NAA. However, the average root length was lower in 14.76 μM IBA in combination with 0.23 μM Kn than in 0.54 μM NAA. Regenerated plants were maintained under normal condition after hardening. Plants, which were rooted on media supplemented with 14.76 μM IBA in combination with 0.23 μM Kn showed higher survival rate during hardening than those rooted on 0.54 μM NAA supplemented media. |

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.
