Abstract
To seek for proper regeneration methods with under-planting, Photosynthetic rate and chlorophyll contents of three broad-leaved species seedlings, Kalopanax pictum, Fraxinus rhynchophylla and Cornus controversa, were measured and compared between growing sites, below the canopy of Larix kaemferi and open land in the forest. Nursery stocks was planted in open nurs- ery in the forest in late April, 1997, and under-planting below the canopy of Larix kaemferi was conducted in late April, 1998. This experiment examined the relationships between shade-tolerance and physiological response to different light environment by tree species. To adapt the shade environment, leaves of Kalopanax pictum might be increased the more chlorophyll con- tents and photosynthetic ability than other species. From these results, shade-tolerance of the tree might be ordered Kalopanax pictum, Fraxinus rhynchophylla, and Cornus controversa.
