| Abstract | We have investigated the effect of storage conditions (duration: 1, 8 or 15 days; temperature: 4°C or 10°C) and root coverage [bare root (BR) or soil-plugged root (PR)] on the water status, electrolyte leakage and root growth potential (number of new roots and new root length) of radiata pine (Pinus radiata D. Don) seedlings. We have also examined the effects that storage causes on plant quality and initial survival potential and their usefulness for detecting physiological damage to seedlings. We observed a gradual decrease of seedling water status and an increase in electrolyte leakage, both in root and shoot, with duration of storage, the latter indicating damage to membranes. Both storage temperature and duration influenced the ability of radiata pine seedlings to initiate and elongate new roots. The effect was more pronounced in BR than in container seedlings, suggesting that the rooting-plug medium provides protection against desiccation. The close relationship (r=0.923, P<0.05) between root growth potential and predawn xylem water potential before transplanting shows that water potential at the time of transplanting is a reliable predictor of the ability to generate new roots. Finally, we have observed a close relationship between survival and parameters such as electrolyte conductivity, post-storage water potential, new root length and root growth potential. |

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.
