abstract = "The study aims to analyze the spectral behavior of leaves of
Eucalyptus globulus attacked in four different severity levels by
Mycosphaerella spp. in different positions in the canopy of the
tree in the four seasons, considering two regions of the
electromagnetic spectrum: visible and near infrared. The plant
material was collected in all seasons, in different positions in
the tree (base, middle and top of the canopy extract). In the
laboratory, leaves were classified into four levels of severity
(healthy, little, medium and heavy fire) and then made
measurements of spectral reflectance measured with a
spectroradiometer. The spectral behavior of Eucalyptus globules
leaves is characteristic according to the severity degree of the
disease, differing primarily in the other high levels of infection
by Mycosphaerella spp. and differ mainly of healthy leaves and
leaves which are little attacked, in both regions of the
electromagnetic spectrum, this behavior occurs for different
treetop positions and climate seasons, varying the amount of
reflected energy. It is concluded that the reflectance of the
Eucalyptus globules leaves attacked by Mycosphaerella spp. differs
according to the position in the tree crown and the weather
station when they were collected and to the advanced levels of
disease severity.",
