Effect of cultural intensity and planting density on wood properties of loblolly pine (Pinus taeda L.)

The effects of cultural intensity (operational and intensive) and planting densities (741, 1483, 2224, and 2965 ha-1) on modulus of elasticity (MOE), modulus of rupture (MOR) and specific gravity (SG) of small clear samples obtained from 15 and 16 year-old loblolly pi...
