Description: Safe storage guidelines are a common tool used to guide farmers to store grain at right temperatures and moisture contents in order to avoid any quantity and quality loss. In Manitoba, Canada, approximately 9% of stored hemp seeds are lost during harvest, handling, and post storage. Therefore, guidelines for hemp seed storage are required. This study determined the effect of temperature (20, 25, 30, 35 and 40?), seed moisture content (relative humidity: 90, 80, 70 and 60%), and storage time (stored for 24 wk) on germination of hemp seeds (variety Finola). Moisture content and germination of the hemp seeds were determined every week. It was found that all the measured variables (relative humidity, temperature, and time) had a significant effect on the germination. Relative humidity and temperature proportionately increased moisture content as well as the faster decrease of germination. There was 85% decrease in germination for samples at ?80% RH stored at ?25? as well as 95% decrease for ?35? at ?70% RH in 7 wk. Hemp seeds with lower relative humidity (70% & 60%) can be stored at temperatures ?25? with higher than 70% seed germination for 24 wk. Based on the 20% initial germination loss, safe storage guideline of hemp seeds was developed.

Keywords: Hemp seed germination, storage guideline, temperature, moisture content, relative humidity.
