Outline of Final Research Achievements

We invested changes during 35 years in xylem structure and widths of annual ring, earlywood and latewood of tree stems of Quercus crispula in Furano, Tomakomai and Ehime. As a result, we found that (1) the earlywood widths changed via the numbers rather than the sizes of earlywood vessels, (2) the widths of annual ring, earlywood and latewood of the tree stems changed during the 35 years, and (3) the changes of the widths depends on the habitats, in the way that it decreased in the southern area (Ehime) while it increased in the northern areas (Tomakomai and Furano). Global warming may enhanced the stem growth of Q. crispula in northern habitats, while it reduces the growth in southern habitats through summer drought.
