Elevated CO 2 enhances the photosynthesis and growth of hybrid larch F 1 seedlings. However, elevated CO 2 -induced change of tree shape may have risk to the other environmental stresses. The hybrid larch F1 (Larix gmelinii var. japonica × L. kaempferi) is one of the most promising species for timber production as well as absorption of atmospheric CO2. To(More)
The hybrid between Kuril larch (Larix gmelinii var. japonica) and Japanese larch (L. kaempferi) is an important afforestation tree species in Hokkaido, Japan, because of its rapid juvenile growth, straight stem, and resistance to bark gnawing by voles. To produce desirable hybrid seedlings, precise seedling discrimination is essential. However, continuous(More)
A recently developed hybrid larch F1 (F1: Larix gmelinii var. japonica × L. kaempferi) is being planted widely in re- and afforestation projects in northeast Asia. Nitrogen (N) deposition to forest ecosystems has been rapidly increasing in this region, due mainly to industrialization and overuse of N fertilizer. Together with excess N, phosphorus (P) is(More)
