Length of shoots and leaves were measured and sampling for microscope observation was done, at vigorous branches in the upper whorls, at monthly intervals respectively. Formation of the new bud began in February and continued until January in the next year and there was no clear period of bud dormancy. During the period from February to June, cataphylls which subtend no axillary buds were formed, and formation of cataphylls which subtend axillary buds initiated in July. Primordia of short-shoot were formed during the period from July to either late December or early January, and primordia of long-shoot in January. The ratio of height to diameter of the shoot apex (shape of the shoot apex) varied with correlation to the each stage of new bud formation. The phase of bud expansion was from September to October and from late February to early May. During the period from September to October, the sterile cataphyll region of the new bud elongated and the bud developed into the candle shoot. The region of cataphylls which subtend axillary buds elongated during the period from late February to early May.","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/20.500.12000/4115"}]},"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.
