Abstract

The effects of defoliation level and timing on growth and survival of young loblolly (Pinus taeda L) and slash (P. elliottii Engelm.) pines were studied in pine plantations in 1986. Five defoliation levels (100, 95, 66, 33, or 0 percent) and four defoliation times (January, April, July or October) were replicated at four Coastal Plain locations (two in Georgia and one each in Florida and South Carolina). Needles were manually removed from the ground up through the crown to simulate scorch effects on foliage. Ninety-three percent of the loblolly pines defoliated 100% in October and 40% of the slash pines defoliated 100% in October were killed. Diameter and height growth of trees defoliated at the three most severe levels were reduced.
