Outline of Final Research Achievements |
To reveal the factor affecting the physiological trait of evergreen conifer Picea jezoensis var. hondoensis trees, sap flux density was investigated for several spruce trees inside the deer-proof fence on Mt. Ohdaigahara where forest decline is outstanding caused by debarking by deer. Among some climate factors, radiation and vapor pressure deficit (VPD) affected sap flow. Diurnal pattern of sap flow showed similarity with those of radiation and VPD. Among some ecological traits of spruce, tree height, debarked ratio, and sap wood area showed positive effect on sap flow. Survived spruce trees may compensate their debarked area of trunk by sap flow rate.
