Family Scientific Name:	Grossulariaceae
Family Common Name:	Gooseberry family
Scientific Name:	Ribes lacustre (Pers.) Poir.
Common Name:	Black Gooseberry
Species Code:	RIBLAC
Ecotype:	Subalpine Forest, Logan Pass, 2032m elev.
General Distribution:	R. lacustre occurs from Alaska to California,east across Canada to Newfoundland, south to Pennsylvania, Michigan, the Dakotas, and south through the Rocky Mountains to Colorado.
Propagation Goal:	plants
Propagation Method:	seed
ProductType:	Container (plug)
Stock Type:	800 ml containers
Time To Grow:	9 Months
Target Specifications:	Stock Type: Container seedling<br> Height: 10 cm<br> Caliper: 9 mm<br> Root System: firm plug in 800 ml container.
Propagule Collection:	Seeds are collected when fruit turns black in late August. Seeds are tan at maturity. Fruit is collected in plastic bags and kept under refrigeration prior to cleaning.
Propagule Processing:	Seeds are cleaned by maceration using a Dyb-vig seed cleaner followed by screening. Seed longevity is unknown. Seed dormancy is classified as physiological dormancy. Seeds/Kg: 1,200,000/kg % Purity: 100% % Germination: 80 to 100%
Pre-Planting Treatments:	Seeds were fall sown in containers to undergo a 5 month outdoor cold, moist stratification.
Growing Area Preparation/ Annual Practices for Perennial Crops:	Outdoor nursery growing facility. Sowing Method: Direct Seeding. Seeds are 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 2 grams of Osmocote and 0.75 gram of Micromax per 800 ml container. Containers are filled and sown in late fall and irrigated thoroughly prior to winter stratification. Seedlings germinate in spring under fluctuating outdoor temperatures and are grown under full sun exposure. Seedlings are irrigated with Rainbird automatic irrigation system in early morning until containers are thoroughlyleached. Average growing season of nursery is from late April after snowmelt until October 15th.
Establishment Phase:	Seeds germinate evenly over a 2 week period. Initial growth of the seedlings is rapid. Seedlings are thinned at 2 to 4 true leaf stage.
Length of Establishment Phase:	4 weeks
Active Growth Phase:	Plants grow rapidly following establishment, and are regularly fertilized with 20-20-20 liquid NPK at 100 ppm. Plants are root tight in conetainers in 1 month. Plants are potted into 800 ml pots. Seedlings reach root-tightness in 3 months.
Length of Active Growth Phase:	16 weeks
Hardening 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:	4 weeks
Harvesting, Storage and Shipping:	Total Time to Harvest: 9 months Harvest Date: July and August Storage Conditions: Overwinter in outdoor nursery under insulating foam and snow.
Length of Storage:	5 months
Other Comments:	This species grows rapidly and 3L (1 gallon) container plants can be produced from seeds in 1 year.
