Macaranga tanarius (L.) MUELL.-ARG. has same situation in the sub-tropical forest of the Ryukyu Islands. Size and chlorophyll content of the leaves of Macaranga tanarius were studied in the southern part of Okinawa Island from November, 1989 to February 1990. Average values of length and width of the blades were 189mm and 127mm. respectively. Average fresh weight of the blades was 3.5g and dry weight ratio of it was 0.3477 in average. Relationship between fresh weight of the petiole and area of the leaves showed high correlation (r=0.9208). Correlation coeficient between lenghth or width of the blades and area of the leaves was high (r=0.9369 and 0.9719), accordingly. leaf area can be estimated by using the length or width of blade. Estimation values of the chlorophyll content of the leaves and the count of chlorophyll meter showed high statistical level in between. Leaf arrangement of a shoot of Macaranga tanarius was mainly desided by the behavior of petiole which is continuing elongation growth after that of blade.","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/20.500.12000/3840"}]},"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.
