FLORICULTURE
To promote the flower industry and to increase the profit of flower growers, the major achievements and directions of floriculture research are:
1. Selection of cultivars easily grown under local conditions: Eustoma, Limonium, Matthola, Phalaenopsis, and Oncidium have been selected for characteristics of adaptability to the climate in southern Taiwan. The new cultivars of Eustoma Tainan #1~6 were not easy rosette after planting. Limonium Tainan #1 and #2 are early-flowering with low vernalization requirement. Matthola Tainan #1 and #2 can distinguish the double flower seedling by leaf green color or shape, which are the most heat-tolerate varieties in Taiwan. New cultivars and 24 single Phalaenopsis plants were transferred to industry for commercial production. For promoting breeding efficiency, the station developed heat tolerance indexing techniques to select plants with high temperature adaptation at the seedling stage.
2. Promoting the management techniques of protected horticulture, such as the development of a summer vegetable/winter flower year-round production system, and the development of drip irrigation and fertigation system. The station has been developed a Phalaenopsis spike-forcing system combining energy conservation, high spatial efficiency, and automation for stable production of cut flowers. This system will be tested for other cut flowers in the future. The Station also will focus on the development of new cultural media, energy and water-saving integrated management to ease the difficulties of farmers.
3. Providing assistance to the export flower market, such as developing new varieties and cultivation techniques and providing a standard postharvest handling procedure for Anthurium and Eutosma. We also will keep providing consultation on cultivation techniques for flowering crops destined for export to increase the competitiveness of Taiwan’s flower industry.

<> <> <> Yuinlin Branch Station’s research efforts include: development of low temperature treatment techniques of Eustoma to break dormancy and improve flower quality for export; decentralization of Oncidium flowering for year-round production; germplasm collection and cross breeding of buttercup orchids; basic studies on the growth and development of Canterbury bell and slipper orchids as potential new flower crops in Taiwan; germplasm collection and selection, and in vitro seedling propagation of slipper orchids. Oncidium Tainan #1 and buttercup orchids Tainan #1 and # 2 were released in 2001 and 2002, respectively.
