Spectral reflectance relationships to leaf water stress

摘要: Spectral reflectance data were collected from detached snapbean leaves in the laboratory with a multiband radiometer. Four experiments designed to study spectral response resulting changes leaf cover, relative water content of leaves, and potential. regions included analysis red (630-690 nm), NIR (760-900 mid-IR (2.08-2.35 microns). The bands showed sensitivity both cover leaves. was only highly sensitive cover. Results provided evidence that governed primarily by moisture content, although soil an important factor when less than 100 percent. High correlations between potentials attributed covariances
