Abstract
Containerized Pinus densiflora seedlings are regularly produced in South Korea. In this study, we identified differences between the root architecture and spatial development of naturally regenerated and artificially planted P. densiflora for. erecta. saplings at 2 sites in northeastern South Korea. The total taproot length was significantly longer in naturally regenerated stands than in planted stands (P < 0.01); the taproots of naturally regenerated saplings grew to a soil depth of 50 cm, but those of planted saplings grew to a soil depth of only 30 cm. The lateral roots of naturally regenerated saplings consistently developed straight and horizontally, tending to decrease in number and length as the soil depth increased; however, the lateral roots of planted trees developed irregularly, and most roots tended to spiral. The root characteristics of the saplings in planted stands were a factor causing deteriorating stability. Continuous monitoring of the root development of older planted P. densiflora for. erecta in various areas and advanced silvi cultural techniques are required to ensure effective growth of these trees.
