Pinus elliottii var. elliottii x Pinus caribaea var. hondurensis has gained importance since the nineties in the province of Misiones, both for its growth and its technological aptitude. The aim of this work was to evaluate the variations in the light environment from different thinning schemes, which combined 3 intensities with 3 frequencies of intervention. Coverage, total incident radiation, leaf area index (LAI) and bunching factor were evaluated. The methodology proposed by Macfarlane et al. for the estimation of LAI from flat photographs was validated. The thinning applied had a…mehr

Pinus elliottii var. elliottii x Pinus caribaea var. hondurensis has gained importance since the nineties in the province of Misiones, both for its growth and its technological aptitude. The aim of this work was to evaluate the variations in the light environment from different thinning schemes, which combined 3 intensities with 3 frequencies of intervention. Coverage, total incident radiation, leaf area index (LAI) and bunching factor were evaluated. The methodology proposed by Macfarlane et al. for the estimation of LAI from flat photographs was validated. The thinning applied had a differential influence on the canopy characterization variables analyzed. The IAF obtained by the methodology proposed by Macfarlane et al. showed similar values to those obtained by allometry.
