Copper-Treated Containers Influence Root Development of Longleaf Pine SeedlingsThis article is part of a larger document. View the larger document here.
Development of longleaf pine (Pinus palustris Mill.) seedlings grown in CopperblockTM containers and BC/ CFC First ChoiceTM Styrofoam blocks, with applications of Spin Out® root growth regulator, were compared to control seedlings. The copper treatments significantly changed seedling morphology; at outplanting, dry weights of both roots and tops were greater than for control stock. Evaluations made 30 days after planting seedlings in a sand stress-bed environment showed that root egress from the treated containers was greater than from the control.
