Description

The Alberta Tree Improvement & Seed Centre (ATISC) conducted a trial with the purpose of determining approximately how long lodgepole pine, jack pine and white spruce seeds need to be in contact with a moist substrate for full imbibition to occur. These results will assist nursery schedule managers in choosing whether or not to skip long soak times due to staffing, imminent holidays, high workloads, last-minute orders, etc. without the worry of sacrificing germination speed, seedling quantity or quality when producing reforestation seedlings for Alberta public land.

Description

Seed testing is done to assess seedlot attributes and determine overall quality and value for seedling production and storage. Seed testing standards are based on scientific evidence and provide set procedures for facilities to conduct tests in a uniform manner and ensure comparable results for seed owners. The seed testing standards described are closely aligned with the International Rules for Seed Testing 2015 (ISTA 2015) and follow these procedures for sampling, moisture content determination, purity analysis, and seed weight determination.
