| Abstract | An experiment was conducted to evaluate the effects of synthesis silver nanoparticles (AgNPs), on the seed germination, germination percentage (GP), seedlings vigor index (VI), germination index (GI), tolerance index (TI), root and shoot length (RL and SL) and silver content in seven varieties of Lycopersicon esculentum Mill (tomato) plants. AgNPs in 50 nm size in five different concentrations, viz, 0, 25, 50, 75 and 100 mg l$^{−1}$ were synthesized by chemical reduction of metal salt precursor silver nitrate. In the first few days of testing, AgNPs treated seeds sprouted within first 3 days, whereas the control seeds (deionized water) took longer time to sprout, that resulted in the increase in GI, in Early urbanay VF, Super strain B and Primo early varieties. AgNPs caused a significant decreased in GP of Super strain B, and Super stone varieties at 75 and 100 mg l$^{−1}$ concentrations. We detected no significant differences in GP in other varieties. AgNPs application to tomato varieties seeds also caused a drastic decrease in VI, TI, RL and SL in all varieties seedlings. The measurement of Ag content, showed a linear increase with the increase in AgNPs concentrations. Finally, phytotoxicity effect of AgNPs was revealed in seven varieties. |

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.
