| Species Code: | DILI | ||
| Ecotype: | Puʻu Pia trail, Honolulu, Hawaiʻi, U.S.A. | ||
| General Distribution: | Mesic to wet forests. Hawaiʻi, all major islands. Tropical Africa, Asia, Australia, New Zealand, Polynesia, and Indonesia. | ||
| Propagation Goal: | Plants | ||
| Propagation Method: | Seed | ||
| ProductType: | Container (plug) | ||
| Stock Type: | Spore | ||
| Time To Grow: | 5 months | ||
| Target Specifications: | Sporophyte development of immature fronds. Hight: 5cm | ||
| Propagule Collection: | Mature fertile fronds were collected when sporangia begin to change from green to yellow. Spores likely dispersed if sporangia are brown and frond is beginning to senesce. | ||
| Propagule Processing: | Collected fertile fronds were washed for removal of foreign spores and left to dry for 1-2 hours. The fronds were then placed into folded paper packets for one week, ensuring the dehiscence of the sporangia (Romanchak, et al., 2005). After spore dissemination, the packets were opened and the loose spores were transferred to a 53 μm sieve (Cole-Parmer®, No. 270) in order to remove any debris. | ||
| Pre-Planting Treatments: | Individual 5.0 mg packets of D. linearis spores were portioned using an analytical balance (Mettler AE100). A fine paintbrush was used to disperse spores onto the medium. The brush was held approximately 5 cm above the medium’s surface and spores were sown by lightly tapping the brush. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Sphagnum moss (Spagmoss, New Zealand) was dampened and microwaved for 5 minutes for sterilization. The moss was then placed in clear plastic container (15x7.5x2.5cm). closed and allowed time to cool. Containers were placed in an air-conditioned room (20°C), on metal shelving, covered in plastic sheeting, under cool white fluorescent lights (~50 μmol⁻²s⁻¹ ) (14/24 hr). Medium should be wetted with deionized water once a month or if no condensation is visible on the container. Gametophytes were sprayed with fertilizer (Organics Rx, Sea-kelp 100 (1tbs/gal)) 30-40 days after sowing. | ||
| Establishment Phase: | Spores to gametophyte. | ||
| Length of Establishment Phase: | 1 month | ||
| Active Growth Phase: | Gametophytes to sporophyte. | ||
| Length of Active Growth Phase: | 5 months | ||
| Length of Storage: | Spores can be stored in fridge. Loss of spore viability after 1 year | ||
