Buried seed populations in the subarctic forest east of Great Slave Lake, Northwest Territories
Buried seeds were studied in the subarctic forest east of Great Slave Lake, N.W.T., where 62 surface samples were collected in upland vegetation of different ages and compositions. No seeds germinated from any of the samples after cold treatment and exposure to warm, moist environment. Seeds were pr...
