ABSTRACT- We have examined UV light induced fluorescence (LIF) as a method for detecting salinity and water stress for Scheonoplectus robustus, S. californicus, Phragmites australis and Distichlis spicata. Plants were grown under controlled conditions in a greenhouse and fluoresced immediately after harvest. Fluorescence responses were measured at four different wavelengths for all treatments and compared. UV laser induced fluorescence, a remote sensing form of the technology, is a promising avenue for remotely assessing the health status of vegetation.
KEY WORDS: light induced flourescence, salt marsh, emergent vegetation, plant physiology
