| Abstract | An efficient plantlet regeneration system for Citrus hystrix DC has been developed in this study. N $^{6}$-benzyladenine (BA) was most commonly used plant growth regulator in micropropagation of Citrus spp. However, our study demonstrated that BA alone was insufficient to induce normal in vitro shoot regeneration of C. hystrix due to the occurrence of leaf senescence on the regenerated shoots. The inclusion of silver nitrate (AgNO$_{3}$) at 10.0 µM into Murashige and Skoog (MS) medium containing 2.22 µM BA could effectively overcome the leaf senescence and improved shoot regeneration from different explants (cotyledonary node, cotyledon, hypocotyl and primary root) of C. hystrix. In the rooting experiment, the application of continuous indole-3-butyric acid (IBA) and naphthaleneacetic acid (NAA) treatment of 4.92, 9.84, 14.76, and 19.69 µM IBA or 1.34, 2.69, and 5.37 µM NAA in combination with 20.0 µM AgNO$_{3}$ resulted in poor rooting of C. hystrix shoots. Rooting was significantly improved upon exposure of shoots to IBA pulse treatment of 9,840 µM for 16 h prior to their transfer on MS medium supplemented with 20.0 µM AgNO$_{3}$. Assessment of various potting mixtures for acclimatization showed medium containing loamy soil: Peatgro: sand (1:1:1; v/v/v) produced high percentage (83.3 %) of plantlet survival. |

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.
