CGRは1期作, 2期作ともに出穂直前頃に最大値を示し, 出穂後は急速に減少した。また, CGRは2期作よりも1期作が高い値を示した。7. 2期作の精籾収量は1期作に比べてかなり低くかった。これは1株穂数, 1穂粒数等のほとんど収量構成要素において, 1期作よりも2期作が劣ったことによると思われる。","subitem_description_type":"Other"},{"subitem_description":"An expriment was carried out to study the characteristics of dry matter production of rice plant in the 1st and 2nd cropping seasons in Okinawa prefecture. Rice variety used in the experiment was Taichung 65,which is a leading variety cultivated in Okinawa prefecture more than 50 years since it was introduced from Taiwan in 1930. The results obtained are as follows. 1. The vegetative stage in the 1st cropping season was about 35 days longer than that in the 2nd cropping season. On the other hand, the ripening period in the 2nd cropping season was about 15 days longer than that in the 1st cropping season. 2. Plant height in both the 1st and 2nd cropping seasons kept growing until the full heading time, but after that, the height did not grow. 3. Throughout the full growing period, the number of stalks was much larger in the 1st cropping season than in the 2nd cropping season. 4. Total dry matter weight, stalk dry matter weight, and panicle dry matter weight increased more rapidly in the 1st cropping season than in the 2nd cropping season. 5. Percentage of panicle dry matter weight to total dry matter weight increased rapidly in the 1st cropping season, and it reached above 50 Percent at harvest time. In the 2nd cropping season, however, it was under 50 percent at harvest time, since it increased slowly. 6. CGR in both the 1st and 2nd cropping seasons showed a maximum value just before the heading time, but after that it decreased rapidly. On the other hand, CGR was higher in the 1st cropping season than in the 2nd cropping season. 7. Winnowed paddy yield in the 2nd cropping season was very lower than that in the 1st cropping season. It is regarded that this is due to the fact that almost all the yield component characters, namely, panicle number per plant, spikelet number per panicle, and percentage of ripening showed lower values in the 2nd cropping season than in the 1st cropping season.","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/20.500.12000/3986"}]},"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.
