Description
Plant Senescence Reflectance Index (PSRI) is designed to detect plant stress and senescence by measuring the ratio of carotenoid to chlorophyll pigments. It is sensitive to changes in leaf pigments that occur during plant aging, stress, or fruit ripening, making it useful for monitoring crop maturity and health status.
