| Family Scientific Name: | Goodeniaceae | ||
|---|---|---|---|
| Family Common Name: | Goodenia Family | ||
| Scientific Name: | Scaveola taccada | ||
| Common Name: | Thoth | ||
| Species Code: | SCATAC | ||
| Ecotype: | coastal strand, Yap | ||
| General Distribution: | Found throughout the central and southern Pacific.It is one of the most common littoral shrubs, often forming dense thickets on rocky and sandy coasts throughout the area. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | 3L (1 gal) polybags | ||
| Time To Grow: | 6 Months | ||
| Target Specifications: | Height: 20 cm<br> Caliper: N/A<br> Root System: Firm Root Plug in container. | ||
| Propagule Collection: | Seeds are hand collected when fruits are white and begin to drop from the plant. Plants produce seeds throughout the year. | ||
| Propagule Processing: | Fruit is a fleshy white berry containing a single seed. Fruits are mashed against screens and washed to remove pulp and extract seeds. | ||
| 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: | 4-6 weeks | ||
| Active Growth Phase: | 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: | 4 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 month | ||
| 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. | ||
