| General Distribution: | Randia carolinensis is a small endemic tree found in the Caroline islands. Pohnpei and Kosrae have the only remaining patches of montane cloud forest in Micronesia. These forests are also unusual because they are among the lower elevation cloud forests in the world, starting bit higher than 450 meters (Raynor 1993). Endemism is high, in part because the islands are relatively close to the floristically rich regions of Southeast Asia and in part because of their isolation and great age. | ||
| Propagation Goal: | plants | ||
| Propagation Method: | seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | 390 to 550 ml(4 to 5 in. )container | ||
| Time To Grow: | 4 Months | ||
| Target Specifications: | Height: 15 cm<br> Firm root plug | ||
| Propagule Collection: | Seeds are hand collected when fruits have matured and begin to drop from trees. Fruits are usually available all year. | ||
| Propagule Processing: | Fruits are mashed against a screen and washed with water to extract seeds. Seeds are planted after cleaning. | ||
| 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 flats 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 Chuuk State nursery has a year round growing season with periods of high rainfall (up to 6400 mm annually). The facility is comprised of a greenhouse, shade structures, 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. We only use organic fertilizers and pest control products and pratices at our nursery. |
||
| 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(v:v:v) sand and compost. |
||
| Length of Establishment Phase: | 4 weeks | ||
| Active Growth Phase: |
Seedlings are ready for transplanting into larger containers at 4 weeks. Following transplanting, seedlings are moved to a larger greenhouse with more temperature variance where they remain for another 4 weeks. Approximately 4 weeks old after transplanting, they are moved to the open growing compound that is covered with a shadecloth during the 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: | 2 months | ||
| Hardening Phase: | Irrigation frequency and duration is gradually reduced for 4 to 8 weeks prior to outplanting. Nursery stock is top pruned as needed. | ||
| 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. | ||
