Family Scientific Name: Clusiaceae
Family Common Name: Mangosteen Family
Scientific Name: Calophyllum inophyllum
Common Name: Biyococh
Species Code: CALINO
Ecotype: Yap
General Distribution: Native from east Africa to Australia and Malesia, now widely planted and naturalized throughout its range, including the south and central Pacific and the Caribbean Islands.
Known Invasiveness: This species is widely introduced throughout other tropical regions of the world where it may be invasive in some areas and invasiveness outside its naturally occurring range is unknown.
Propagation Goal: plants
Propagation Method: seed
ProductType: Container (plug)
Stock Type: 3L (1 gal) polybags
Time To Grow: 1 Years
Target Specifications: Height: 20 cm<br> Caliper: N/A<br> Root System: Firm Root Plug in container.
Propagule Collection: The fruit is 2-4 cm in diameter and contains a single seed. The fruits are ripe when flesh is yellow or brown and wrinkled (not green and smooth). Fruits may be collected from the ground as late as a few weeks after maturing and dropping and still maintain viability.
Pre-Planting Treatments: Seeds are soaked in water to remove any inhibitors and to allow full imbibition of seeds prior to sowing. Seeds are sown into deep flats (1X2') and covered with composted leaf mold. We transplant viable germinants into containers as soon as the radicle emerges. Flats are checked for new germinants daily.
Growing Area Preparation/
Annual Practices for Perennial Crops:
The Yap Agroforestry nursery a year round growing season with periods of high rainfall.
The facility is comprised of one large greenhouse, shade structures, and mist propagation beds, and an outdoor growing compound. All propagation environments are utilized at different stages of seedling growth to protect seedlings from heavy rains, and provide to temperature and shading variance during production. We irrigate all containers by hand, but are investigating a sub-irrigation system for the nursery. We use fertilizers if when they are available.
Establishment Phase: Seedlings are germinated in a greenhouse were they remain for 4 weeks. Flats and containers are watered by hand.
After seedlings are well established and have at least 2 true leaves, they are transplanted into 3 L (1 gallon) polybags filled with a growing medium of 2:1:1 (v:v:v) sand, seaweed compost, and topsoil.
Length of Establishment Phase: 2 months
Active Growth Phase: Seedlings are ready for transplanting into larger containers at 4 weeks.
Approximately 4 weeks after transplanting, seedlings are grown under a shadecloth during summer months. During months of intense summer heat, containers are watered daily with occasional deep irrigation to leach out accumulated salts.
Length of Active Growth Phase: 8-9 months
Hardening Phase: Irrigation frequency and duration is gradually reduced for 4 to 8 weeks prior to outplanting. Nursery stock is top pruned at this stage.
Length of Hardening Phase: 1-2 months
Harvesting, Storage and Shipping: Containerized seedlings are stored in the open growing compound until moved to outplanting site.
Length of Storage: Variable; depends on outplanting date.
