Key messageSeedlings of two birch species were grown in serpentine soil, withBetula ermaniishowing high tolerance. Abstract Betula ermanii and Betula platyphylla var. japonica, two typical light-demanding-deciduous trees in northern Japan, usually invade disturbed areas. B. ermanii can invade serpentine soil and grow in it, whereas B. platyphylla var. japonica can hardly regenerate in...
Japanese larch (Larix kaempferi) grows at a relatively high rate in northern Japan, even in serpentine soil. Serpentine soil has high concentrations of heavy metals (Ni, Cr), excessive Mg, and is nutrient deficient. These factors often suppress plant growth. We examined the mechanisms of Japanese larch’s tolerance to serpentine soil. We compared growth, photosynthetic capacity, and concentrations...
Sakhalin spruce (Picea glehnii), a native species typically found in northern Japan, has been used in reforestation on hillsides exposed to strong winds. In the reforestation areas, there are south-facing (S-slope) and northwest-facing slopes (NW-slope). Climatic conditions are contrasting between the two slopes, with shallower snow cover on the S-slopes. We compared growth responses of the spruce...
Picea glehnii is distributed widely on serpentine soils in northern Japan. Serpentine soil is characterised by the presence of heavy metals (Ni, Cr) and excessive Mg; these elements often suppress plant growth. We have examined the tolerance to serpentine soil and its effects on growth of P. glehnii, P. jezoensis (distributed in the same region) and P. abies (planted for timber production). The dry...
