Abstract
Effects of flooding and following dry condition on growth and stomatal conductance were studied for 5 Salix species distributed in Kinki district. Adventitious roots were formed earlier in lower river distribution than that in mountainous and upper river distribution. Salix species distributed in lower river floodplain had high stomatal conductance in flooding condition, so these species seemed to have resistance for flooding. These species died in relative higher water content than in mountainous and upper river distribution in the following dry condition.
