Description:
The response of 10 open-pollinated tamarack (Larixlaricina (Du Roi) K. Koch) families to three soil types and three phosphorus fertilizer levels was investigated in a greenhouse for 26 weeks. Characters assessed included height, root collar diameter, dry weights, and phosphorus concentration and accumulation. Estimates of variance components and stability parameters were made. Variation due to soil types, phosphorus treatments, and families was significant for all characters. The family × soil interaction was not significant for any character. The family × phosphorus interaction was significant in some cases, but its magnitude was relatively small. In comparison to earlier studies with nitrogen, genetic differentiation in response to phosphorus is less pronounced.
