In the light\\nof the basic principle of self-thinning that the relative growth rate of mean phytomass\\n(l/u>) (dw/dt) is given by the sum of the relative growth rate of yield (1/y) (dy/dt) and\\nthe relative mortality (-1/P) (dP/dt), the first assumption brings to the conclusion that the\\nfinal yield Y(t) is not prescribed by W{t) P , but is prescribed by(l-tn/A (t))W(t) P\\n(ro, relative mortality; A (f), coefficient of growth), whose value depends on density P\\nexcept for the special case where both Wit) P and m are independent of P. This inevitable\\nconsequence is in conflict with the prescription referring to the final yield Y(t) in the\\nsecond assumption of the logistic theory of plant growth. As a result, it is suggested\\nthat an alternative theory for the density effect in self-thinning populations should be\\nnewly constructed to harmonize the assumption referring to the growth of mean phytomass\\nwith the assumption referring to the law of constant final yield.","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":"琉球大学理学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/11819"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0286-9640"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250774"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学理学部紀要"},{"subitem_1522650068558":"en","subitem_1522650091861":"Bulletin of the College of Science.
