The results obtained were as follows; 1 Starch was prepared from the leaves of Kuwazu-imo by the yeild of 0.34% of the fresh tissues. Amylose and amylopectin were prepared from 1.00g of the starch by the yield of 22% and 74%, respectively. 2 The iodine coloration spectrum of starch, amylose and amylopectin showed the characteristics of their own. The content of starch in the leaves of Kuwazu-imo was constant in the day time and kept high value, however it showed low value in the night time. The amylopectin/amylose ratio of Kuwazu-imo showed high value in the night time but showed low value in the day time. Quantitative determinations of starch in the leaves of Kuwazu-imo were carried out throughout five months. The content of starch reached the maximum value in October, and the value gradually decreased from November till January.","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/20.500.12000/4026"}]},"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.
