| Research Abstract |
The object of this report is to consider the dendrochronology on the cell-arrangement patterns of Coniferous-Wood. The results are summarized as follows; (1) On the sample wood (SUGI,HINOKI,KUROMATU) , the trend of cell-arrangement patterns is given by regression equation from annual age and ring-width. (2) In a stem of SUGI (Pref.MIE, 46 age) , the cell-arrangement patterns are found a correlation between two grand-height (1m and 11m). (3) In a same growth place (Pref.GIFU), the cell-patterns of HINOKI are found a correlation between two sample wood (same 232 age). But, in a difference area not found a correlation (Pref.NAGANO, 244 age). (4) In a stem of KUROMATU (Pref.MIE, 46 age), the cell wall-thickness patterns are found a influence by meteorological phenomena.
