This experiment was carried out in order to clarify the physiological and ecological aspects of the growth of Ceratobium - Phalaenanthe group of Dendrobium which is cultivated as cut flowers. It also was done that comparison on the growth characteristics and changing of growth cycle from budding to flowering related with cultivars. The outline of obtained results are as follows.1. Under the subtropical climate such as Okinawa, flowering time is restricted in around October that is firmly regulated by budding time of new sprout which means maturity of shoot is more dominant factor for flowering. 2. There are considerable differences among cultivars not only on the duration of vegetative growth but also on the various characteristics related with flower. 3. As the result of the culture under the controlled environment by using phytotron, this group of Dendrobium is recognized as a plant having strong resistance for high temperature more than 40 C in day time. 4. With the style of photosynthesis, it was clarified that this group of Dendrobium belong to CAM plant because CO_2 was fixed in night time. 5. With the phenomenon of the dropping of flower bud happened before flowering, it was affected by high moisture and a sudden change of temperature, as same as with amount of ethylene produced from flower bud.

本试验是为了阐明切花石斛属的Ceratobium-Phalaenann群生长的生理生态特性。并对不同品种间的生长特性及从现蕾到开花的生长周期变化进行了比较。取得的成果概要如下：1.在冲绳等亚热带气候条件下，花期受新芽萌发时间的制约，主要集中在10月份左右，说明枝条成熟度是影响开花的主要因素。2.品种间不仅在营养生长历时上存在较大差异，而且在与花相关的各种性状上也存在较大差异。3.通过人工气候室在人工气候室的控制环境下进行培养，初步认为该菌是一种对白天40℃以上高温有较强抵抗力的植物。4.结合光合作用方式，明确了这类石斛属植物属于CAM植物，因为CO_2是在夜间固定的。5.花芽脱落现象发生在开花前，受高水分和温度突变的影响，花蕾产生的乙烯量也受到影响。
