Agri-Biotechnology Research LaboratoryAfforestation technology
Nippon Paper's Overseas Plantations
Nippon Paper promotes afforestation in four oversea countries for the purpose of the use of the wood resources not only as pulp and paper but also as energy or biochemical purposes.
Technological development to improve plantation productivity
Agri-biotechnology Research Laboratory dispatches staff to overseas and conducts technology development to increase biomass productivity of plantations.
Among Nippon Paper's plantations, AMCEL in Brazil has 133,000 ha (including 62,000 ha of already planted area) of land available for plantation.
Fast improvement of plantation tree growth
For the purpose of stable procurement of wood resources and environmental conservation, We, together with local staff at AMCEL, engage in the following initiatives to improve MAI (Mean Annual Increment) plantation trees.
(1)Genetic improvement of plantation tree
(2)Development of fast analytical methods for tree components
(3)Improvement of growth environments
Genetic improvement of plantation tree
We have begun developing superior trees by clonal propagation by cuttings with selected elite trees from experimental plantations (selection breeding) or cross-breed those elite trees (hybridization breeding). We also apply genome analysis and DNA marker information to achieve more efficient breeding utilizing gene tracking and DNA marker breeding.

Development of analytical methods for forest wood
We are developing forest mensuration technique to evaluate plantation tree more rapidly. Moreover, to further expedite wood quality evaluation, we are working on the development of analytical methods for forest wood, including microscopy-based observation, basic density analysis using Pylodin method, and analysis of wood components with near infrared-spectroscopy (NIRS).

Improvement of growth environments
We conduct soil investigation and growth examination to develop monitoring method such as, large-scale soil sensing, for sound growth of elite trees. With cooperation from local staff, we aim to improve the growth environment for afforested trees.
