The shoot length was measured at vigorous branches in the upper crown and the samples for observation of cambial activity were taken at the breast height, at monthly interval respectively. The shoot of Sugi elongated from March to September and that of Hinoki from April to October. In Sugi, the cambial activity began in early March and continued until October. The number of cells in the primary wall zone increased in March and was approximately constant from March to August and then decreased until November. The formation of secondary wall initiated in late March and ended in late November. It was therefore proved that wood formation of Sugi initiated in early March and ended in late November. In Hinoki, the division of cambial cells initiated in middle April and stopped in November. The number of cells in the primary wall zone increased in April and was approximately constant from May to September and then decreased until December. The formation of secondary wall began in early May and ended in December except several xylem cells near the cambial zone. As their secondary wall may be formed in next season, it was proved that wood formation of Hinoki initiated in middle April and ended in December. The formation of latewood began in middle July in Sugi and in middle October in Hinoki. In both Sugi and Hinoki, elongation growth and cambial activity initiated almost simultaneously, and cambial activity stopped about one month after elongation growth ended.","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/20.500.12000/4072"}]},"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.
