In order to extend the business, Taiwan Sugar Corporation has invested nurseries for forcing flower in Canada and in America, and seedling production nursery in Costa Rica. Please visit the following websites for detailed information.
Breeding program: Taiwan Sugar owns over 20 native species and 500 superior varieties/lines for breeding purposes. More than 200 crosses are made every year. Seedlings from selected crosses are not only evaluated in our nurseries in Taiwan, but also evaluated in our nurseries overseas.We have a virus-free greenhouse which provides warm and cool climates so that crossing can be made all year round.? Parent plants are screened with ELISA and RT-PCR techniques for virus on a regularly basis to guarantee virus-free seedlings.
Mericlone mass production: We produce 2 millions of mericlone plants in 2007, about 40% of the total production. The percentage will increase 12% every year, and eventually reach the goal of 90% mericlones and 10% seedlings. Our mericlones are propagated with shoot-by-shoot tissue culture. Protocorm-like-bodies (PLB) method is still developing and used on some specific varieties only.
Virus-free seedling: We use a very strict method to guarantee our mericlone plants virus-free. Chosen plants have to pass the virus screen (ELISA and RT-PCR) before putting into the production pipeline. More virus screen was conducted from mother flask to the last stage flask. These are to ensure every mericlone phalaenopsis from Taiwan Sugar virus-free.
Forcing Flower:64 oF night temperature and 77 °F day temperature are ideal temperature settings for forcing flower of most Phalaenopsis varieties. Uniform spike initiation can be expected in 4-6 weeks, and plants will be ready for sale in another 3 months with one to two flowers open. Time required may vary, depending on variety and plant conditions.
After spike initiation, the time needed to the first flower open can be manipulated, either push it by increase the temperature or slow it down by low the temperature, depending on when market need it. Increasing the temperature will run a risk of getting fewer bud counts and definitely high energy cost. Low the temperature might run a risk of bud drop caused by the cold.
Light is also an important factor in forcing flower process. Higher light intensity will give better flowering quality, only if the light does not reach the level of burning the leaves or increasing the temperature in the greenhouse too much.
Orchid Care: Phalaenopsis (fah-lay-NOP-sis), commonly referred to as the "Moth Orchid," are considered one of the easiest orchids to grow in the home. The long lasting flowers bloom in perfection for up to three months. While the flowering season may vary, the plant can bloom more than once during the year. Phalaenopsis have become one of the most popular varieties of orchids due to their easy care and delicately poised vibrant floral formations.
Temperature: Day 70 -90 °F, Night 60 -70 °F.Water: Every 5-7 days if growing in bark or every 10 days if growing in sphagnum moss. Keep evenly moist. Avoid wet foliage at night.
Light: Moderate indirect light. No direct sun.
Fertilizer: Twice a month, less in winter.
Humidity: Phalaenopsis enjoy moist air. 55-75% humidity is ideal. Humidity can be increased by placing plant over a tray of water with some pebbles or rocks etc. to raise the pot above the water.
Repotting: Plants should be repotted every other year. Since Phalaenopsis grow upwards, they can be repotted into the same sized pot. A medium grade fir bark works well with the base of the bottom leaf at the surface of the medium. Water sparingly until new roots have established.
