Abstract

The objective of this study was to evaluate the performance of different spectral indices - MCARI705, R750/R700, R750/R550 and MTCI - in the description of chlorophyll seasonal dynamics in detached leaves of Eucalyptus grandis in four seasons. The study was conducted in three plots of 600 m2, in a 20 months old stand. We collected 15 leaves from three layers of canopy, totalizing 45 leaves for each season. It was used a spectroradiometer FieldSpec®3, which covers the spectral range from 350 to 2,500 nm. Variance analysis (ANOVA) and Tukey test at 5% significance level were carried out. For all spectral indices, values observed in spring were different from those from summer; the same occurred between fall and winter.
