Abstract :本研究は沖縄地域におけるセミノールの生態について調査を行なったもので, 次の諸点が明らかとなった。1.開花期は3月下旬から4月上旬で比較的安定している。2.糖は2月中旬に12.5∿13.5度に達し次第に減少する。3.酸は経時的に減少し, 3月の上旬までに1.2∿1.5度まで低下する。4.1月中旬で完全着色となり3月上旬から次第に退色する。5.葉果比は35枚内外で300g以上となり, 30枚以下でも隔年結果性は認められず, 多肥, 多収の性質を有している。
This paper is to study on the ecology of Seminole tangelo in Okinawa district. The result obtained are briefly summarized as follows; 1. The blooming time of Seminole tangelo is every which during the end of March to first of April. 2. The highest sugar content of Seminole tangelo is 12.2 to 13.5 percent in the middle of Febrary. The content reducing slightly after that. 3. The acid content becomes reduced starting early December. It is less than 1.2 to 1.5 percent by early March. 4. The fruit complete coloring falls in the middl of January and begins lesscoloring at early March. 5. Therty five leaves are needed to make one fruit of more than 300g.
