Flexural properties of Pinus patula planted at different initial spacing

We present a dataset of wood and lumber properties collected from an 18- and 19-year-old <i>Pinus patula</i> Schiede ex Schltdl. &amp; Cham. spacing experiment with four levels of initial tree spacing (1.83 m × 1.83 m, 2.35 m × 2.35 m, 3.02 m × 3.02 m and 4.98 m × 4.98 m). The effect of initial tree spacing was evaluated on radial strips of wood, which were collected from both experimental sites, and lumber that was sawn from logs harvested from one of the plantations.
