In the light\\nof the basic principle of self-thinning that the relative growth rate of mean phytomass\\n(l/u\u003e) (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.
