Abstract
To create consistent spectral data for evaluating geographical, chrono logical, and environmental differences or events in main Scots pine po pulations in Finland and Sweden, reflectance spectra from randomly sam pled single pine individuals (N = 2069) were measured. The spectra wer e recorded in 1991-1993 during and after the growing season by using a mobile spectroradiometer working in the 390-1070 nm wavelength range. The spectral data was processed by using three independent statistica l pattern recognition methods. Typical spectral shape differences betw een the growing seasons were observed due to the obvious phenological phase shift from year to year. This was verified by the observed diffe rences inside the growing season. Longitudinal distinguishing characte ristics of the pine spectra were greater than latitudinal ones. We are also able to classify pines growing in polluted and less polluted env ironments to the corresponding classes.
