Vessel diameter and area fraction was measured by the digitizor with a personal computer and the dot-grid eyepiece. Vessel diameter and area fractions of elements in early and late wood were disscused and distinction of the measured values was drawn between early and late wood. Vessel diameter of examined diffuse porous woods were varried at the position of a growth ring and had some variation patterns of vessel diameter in one growth ring. Vessel diameter and area fraction of elements were different early wood and late wood in statistically and both values were greater in early wood than late wood. It was drawn from the relation between vessel diameter and area fraction of vessels as follows : vessels of KUSUNOKI, SHIBANIKKEI and YABUNIKKEI wood had a tendency to scatter in some area fraction and vessels of ISUNOKI wood had a tendency to scatter in some vessel diameter. Area fraction of vessels was greater than fraction of fibers in KATSURA wood and area fraction of fibers was over 0.50 in other six woods.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学農学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/3883"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0370-4246"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250548"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学農学部学術報告"},{"subitem_1522650068558":"en","subitem_1522650091861":"The Science Bulletin of the Faculty of Agriculture.
