The resultant equation takes the same reciprocal form as the reciprocal equation derived from Shinozaki-Kira\u0027s theory, i.e., the\\nlogistic theory of the C-D effect, which deals with the density effect occurring in nonself-thinning populations. It is, however, recognized that one of the two coefficients is quite different in mathematical interpretation between the two reciprocal\\nequations based on the present theory and the logistic theory of the C-D effect, respectively. The present conclusion is consistent with the empirical facts that the reciprocal relationship between yield (or mean phytomass) and density is discernible\\nin not only nonself-thinning populations, but also self-thinning populations. The\\npresent model is expected to systematically interpret underlying mechanisms be\\ntween the density effect, which is observed at a time constant among populations\\nvarying in initial density, and self-thinning, which is observed along a time continuum in any given population.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u7406\u5b66\u90e8"}]}, "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/20.500.12000/11817"}]}, "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": "\u7409\u7403\u5927\u5b66\u7406\u5b66\u90e8\u7d00\u8981"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "Bulletin of the College of Science.
