A possible reason for this phenomenon is descussed in relation to the different elevations of the plants and the respective temperature changes. Investigations were carried out by dividing 10 grades on flowering and leaf expanding aspects. The outline of results obtained are as follows. 1. Along the road side at Yaedake mountain, earliest flowerings were observed at higher places than 290m elevation and followed at lower places below 100m elavation. On the middle places between 100 and 290m, the flowering time was delayed and differences by each trees was great. 2. The general tendency of flowering time, including all trees at the mountain road, showed that they flowered as early as elevation goes up, however it showed minimum significant difference. 3. Locational difference between the northern and southern areas with flowering time, the former area was earlier compared to the lower places in Yaedake area, however it was not a significant difference compared with those of middle places. 4. Higher temperature than lowest winter temperature in Okinawa is needed to flowering of P. campanulata. Due to this reason, trees at higher places or colder places which encounter the low temperature in December or January can open flowers at an earlier time.", "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/20.500.12000/3786"}]}, "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.
