Presowing, Stratifying Spruce and Pine Seed in Plastic Containers Proves Best in Alberta, Canada, Test

The Provincial Tree Nursery, Edmonton, Alberta, Canada, recently tested two methods of handling white spruce and lodgepole pine seed to obtain highest germination and survival when sown in cardboard and plastic containers. The trial consisted of the following treatments with 50 plastic and 50 cardboard containers each, replicated three times for each species for a total of 4,800 individual seed tests: (a) A check with untreated seed. (b) Seed presown in containers and stratified for 90, 60, and 30 days at 34°F. (c) Seed cold-soaked for 30, 20, and 10 days, and sown in containers. (d) Pregerminated seed, sown after 4 days in blotters at greenhouse temperature. Cardboard and plastic containers, both 21/2 inches long and 3/ inch in diameter, were used; One seed was sown in each. The soil mix was one part sand to two parts loam. Seed was from the Hinton area. Seed was germinated under mist in the greenhouse-the mist was on seconds every 10 minutes in daylight hours only. Greenhouse temperature was held at 65°F., and good air circulation was provided. A gallo drench was applied the soil after germination.
