Outline of Final Research Achievements

This study was conducted to reveal the relationship between the loss of hydraulic conductivity in xylem after transplants and the mortality ratio among species. The vulnerability curve was drawn to explain the relationship between water stress and the loss of hydraulic conductivity among species. Dead saplings with increasing the amount of pruned roots were detected in ring-porous species forming long vessels and in species that was more vulnerable to water-stress-induced embolisms, and the conductivity in these species significantly decreased with the treatment of root pruning. On the other hand, in Japanese cedar of high resistance to water-stress-induced embolisms, the loss of hydraulic conductivity was induced regardless the amount of pruned roots. This result suggests that the water in xylem may be used to form the new roots after transplants.
