Abstract 2831 The Impact of Short Wavelength UV-B Radiation on Texas Native Grasses B. curtipendula and C. latifolium

Two Texas grasses, B. curtipendula (sideoats) and C. latifolium (seaoats), exhibit unique responses when exposed to different ranges of UVB (280-320 nm) radiation: full spectrum UVB radiation, long wavelength UVB (>300 nm) radiation, or no UVB. Once matured in the Trinity University greenhouse, plants were exposed to these different ranges of the UV spectrum through three chambers with differing excluding or transmitting filters to administer specified ranges of radiation - aclar (AC, UVB transparent), cellulose acetate (CA, blocks <300 nm), and polyester (P, blocks >320 nm).
