- Abstract
Hesperozygis ringens is a species that stands out for the production of essential oil. No reports on the leaf spectral characterization of the species have been found. This study aimed to determine the reflectance pattern of Hesperozygis ringens leaves with the aid of Remote Sensing. Therefore, a spectroradiometer that operates in the continuous spectral range from 400 to 900 nm of the electromagnetic spectrum was used, with a resampled precision of 1 nm. The reflectance measurement was collected in situ. Four records were obtained. A spectral curve was created from the means of measurements in each sample. In the blue region, reflectance values between 0.0116696 and 0.0399550 were found. In the red region, the reflectance oscillated between 0.0438487 and 0.1095826. In the green region, the reflectance values ranged between 0.0405677 and 0.1001319. In the near-infrared region, the oscillation of reflectance values occurred between 0.1163483 and 0.4655269. The results indicate the effectiveness of the use of geotechnologies to carry out the spectral characterization of the H. ringens leaf. Further studies are expected to identify and monitor plant populations with Remote Sensing.
