|Family Scientific Name:
|Family Common Name:
||Amelanchier alnifolia Nutt.
||Forest margin, Middle Fork Flathead River, 1100m elev. Glacier National Park, Flathead Co., MT
||A. alnifolia occurs from southern Alaska to California, east across Canada to western Ontario, south through the Rocky Mountains to New Mexico, and east to the Dakotas and Nebraska, in open forests, canyons, and hillsides from near sea level to the subalpine zone.
||172 ml conetainer
|Time To Grow:
||Stock Type: Container seedling
Height: 10 cm
Caliper: 7 mm
Root System: Firm plug in conetainer.
||Seeds are hand collected in late summer when fruit turns dark purple. Seeds are brown at maturity. Fruits are collected in plastic bags and kept under refrigeration prior to cleaning.
||Seeds are cleaned by maceration using a Dyb-vig seed cleaner followed by screening. Seeds are cleaned at NRCS.
Seed longevity is 5 to 7 years at 3 to 5C in sealed containers.
Seed dormancy is classified as physiological dormancy.
% Purity: 100%
% Germination: 15 to 100%
||Seeds are placed into a 3:1 water/3% hydrogen peroxide rinse for 10 minutes followed by a 48 hour running water rinse.
Seeds are placed into a 120 day cold, moist stratification. Seeds are placed in fine mesh bags and buried in milled sphagnum peat moss in a ventilated container under refrigeration at 1 to 3C.
It is very important to wash stratified seeds weekly. Remove net bags from artificial stratification and rinse well to remove mucilaginous material.
Lower germination percentages were noted with seed lots that did not receive the hydrogen peroxide: water rinse prior to stratification. This pretreatment of seeds appears to significantly improve germination percentages.
|Growing Area Preparation/
Annual Practices for Perennial Crops:
Greenhouse and outdoor nursery growing facility.
Sowing Method: Direct Seeding. Seeds are lightly covered with medium.
Growing medium used is 6:1:1 milled sphagnum 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.
Greenhouse temperatures are maintained at 21 to 25C during the day and 16 to 18C at night. Seedlings are hand watered and remain in greenhouse until mid May. Seedlings are then moved to outdoor nursery for the remainder of the growing season.
Seedlings are irrigated with Rainbird automatic irrigation system in early morning until containers are thoroughly leached.
Average growing season of nursery is from late April after snowmelt until October 15th.
||Germination is uniform and is usually complete in 3 weeks. True leaves appear 2 weeks after germination. Seedlings are thinned at this stage.
|Length of Establishment Phase:
|Active Growth Phase:
||Seedlings grow at a rapid rate after establishment. Plants are fertilized with 20-20-20 liquid NPK at 100 ppm during the growing season. Plants average 10 cm in height/7 mm caliper in 4 months.
|Length of Active Growth Phase:
||Plants are fertilized with 10-20-20 liquid NPK at 200 ppm during August and September. Irrigation is gradually reduced in September and October. Plants were given one final irrigation prior to winterization.
|Length of Hardening Phase:
|Harvesting, Storage and Shipping:
||Total Time To Harvest: 11 months
Harvest Date: September
Storage Conditions: Overwinter in outdoor nursery under insulating foam cover and snow.
|Length of Storage:
|Outplanting performance on typical sites:
||Outplanting Site: Saint Mary, Glacier National Park, MT.
Outplanting Date: Spring or Fall
Outplanting Survival at 4 years: 86%
