Induced Response of the Siebold's Beech (Fagus crenata Blume) to Manual Defoliation

Abstract. The 1995 Mw 7.2 Kobe earthquake produced an ~ 18 km-long surface rupture zone with a maximum right-lateral displacement of ~ 1.8 m along the pre-existing active Nojima Fault in southwest Japan. Field investigations showed that the co-seismic surface ruptures caused severe damage to trees, some of which survived the disaster during the past twenty years along the co-seismic fault scarp. Analysis of tree-rings from the trunk of a 46-year-old Beech tree (Fagus crenata Blume) revealed that the tree was cracked by earthquake-induced damage and that the tree-rings grown during the five-year period after the 1995 earthquake become sharply narrower in width compared to those grown before the earthquake. Our findings indicate that the earthquake damaged trees along the co-seismic fault scarp and hindered the growth of tree-rings by severing the roots. Thus, the results support the idea that older trees growing along or around fault zones can be used for identifying seismic fault events and for dendrochronological studies related to geomorphological processes.

Elemental Maps

Micro-beam scanning PIXE and scanning transmission ion microscopy (STIM) were applied to measurement of Siebold's beech (Fagus crenata Blume) leaves. The beech leaf samples were collected from selected beech trees at Tsugaru Pass near the Shirakami-Sanchi World Heritage Area, in the 1999 growing season. We focused our interest on the influence of the atmospheric environment (acidic deposition, aerosol and gaseous substances, etc.) on the forest ecosystem. Our approach to real images of the deposition of airborne particulate on leaves led to the elucidation of the process of elemental absorption from air and plant metabolism. As a result, it is suggested that 1) overlapping STIM images and elemental maps demonstrate the patterns of the elemental absorption into plants, 2) comparison of the elemental maps of leaves taken at the different growth stages may provide useful clues to the elemental accumulation mechanism in leaves, and 3) silicon distribution in leaves is indicative of airborne particulate deposition on them.

Fagus Crenata Blume

Pollen-mediated gene flow was analyzed in a small, fragmented, natural population of Fagus crenata Blume by surveying five microsatellite markers in seedlings derived from open-pollinated crosses. Paternity of 162 seedlings derived from two maternal trees was assigned by the maximum-likelihood method using CERVUS 2.0, and pollen dispersal patterns within the study site were determined. Most of the trees within the site sired seeds, although we found evidence of limited pollen-mediated gene flow from outside the stand; 92% of the matings that generated the seedlings occurred between trees within the population, and 8% of the matings were mediated by pollen derived from trees located outside the study site. Although the pollen-mediated gene flow within the site was not strongly limited, mating frequencies of paternal trees were found to be weakly negatively correlated with their distance from the mother trees, positively correlated with their stem diameter at breast height, and uncorrelated with their relatedness to the mother trees.
