| ProductType: | Container (plug) | ||
| Stock Type: | 172 ml conetainers | ||
| Time To Grow: | 6 Months | ||
| Target Specifications: | Height: 4 cm, 6 to 10 true leaves<br> Caliper: n/a<br> Root System: firm plug in 172 ml conetainer. | ||
| Propagule Collection: |
Seeds are hand collected in late August when achenes turn gray and are easily removed from the disc. Seeds are collected in paper bags and kept in a well ventilated drying shed prio to cleaning. |
||
| Propagule Processing: |
Seeds are hand cleaned using screens. Seed longevity is estimated at 5 to 7 years. Seed dormancy is classified as non deep physiological dormancy. Seeds/Kg:1,200,000/kg % Purity: 100% % Germination: 50% |
||
| Pre-Planting Treatments: | Dry storage of seed for 5 months. | ||
| Growing Area Preparation/ Annual Practices for Perennial Crops: |
Greenhouse; 22C/13C day/night temperature cycle. Sowing Method: Direct Seeding. Seeds are covered with media. Growing media used is 6:1:1 milled spaghnum peat, perlite, and vermiculite with Osmocote controlled release fertilizer (13N:13P2O5:13K2O; 8 to 9 month release rate at 21C) and Micromax fertilizer (12%S, 0.1%B, 0.5%Cu, 12%Fe, 2.5%Mn, 0.05%Mo, 1%Zn) at the rate of 1 gram of Osmocote and 0.20 gram of Micromax per 172 ml conetainer. |
||
| Establishment Phase: | Media is kept slightly moist during germination. Initial germination appeared uniform. Do not over water seedlings. | ||
| Length of Establishment Phase: | 4 weeks | ||
| Active Growth Phase: | Root and shoot development occurs rapidly following germination. Plants were fertilized with 20-10-20 liquid NPK fertilizer at 100 ppm during the growing season. | ||
| Length of Active Growth Phase: | 16 weeks | ||
| Hardening Phase: | Irrigation is gradually reduced in September and October. Plants are leached with clear water and fertilized with 10-20-20 liquid NPK fertilizer at 200 ppm. | ||
| Length of Hardening Phase: | 4 weeks | ||
| Harvesting, Storage and Shipping: |
Total Time To Harvest:6 months Harvest Date: July Storage Conditions: Overwinter in outdoor nursery under insulating foam cover and snow. |
||
| Length of Storage: | 5 months | ||
