| Abstract | Seed transfer regulation in forest trees is to prevent the plantation of maladapted trees in non-local sites. Seed transfer from southern to northern Japan is prohibited in Japanese red pine (Pinus densiflora). To evaluate the current regulation of seed transfer, a reciprocal transplant trial was conducted in P. densiflora trees originating from two provenances in southern (S) and northern (N) Japan and planted in sites S and N near these provenances. We observed survival rate at 0–15 years old before a thinning and at 15–30 and 15–40 years old after the thinning and measured diameter, per-planted-area cross-sectional area, and shape of stems of 30-year-old trees. The survival rate before the thinning was lower in provenance S than in provenance N and in site S than in site N. The survival rates after the thinning were lower in non-home sites, in particular, provenance S in site N. The stem diameter was largest in provenance S in site S, smallest in the both provenances in site N, and intermediate in provenance N in site S. Thus, trees were fewer and larger in provenance S than in provenance N in their home sites. As a result, the per-planted-area stem cross-sectional area of 30-year-old trees was smallest in provenance S in site N, suggesting a disadvantage of northward transplantation. Proportions of trees with broken and/or crooked stems were higher in site N than in site S, suggesting that a northern environment is more stressful. These findings support the current regulation of seed transfer directions in Japanese P. densiflora. |

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.
