The effects of the ultraviolet absorbing substance palythine from the red alga Chondrus yendoi were investigated. Glass slides on which the spores of Palmaria palmata had been placed were immersed into seawater containing a various concentration of palythine, and these experimental sets were irradiated with UV and then incubated at 10℃, 10L : 14D in a culture medium without palythine. The results obtained show that seawater containing dissolved palythine protected the young sporophytes of P. palmata from UV-B (280〜320 nm), allowing them to develop. The protective rates on 0.1,0.3 and 0.5 kJ/m^2 Damaging-UV (DUV) from the UV irradiation were measured for 0.01,0.03,0.05,0.07 mM palythine respectively. The protective rates for 0.1 kJ/m^2 DUV were about 16.84%, 32.15%, 54.20%, 83.48% respectively. For 0.3 kJ/m^2 DUV, the protective rates were about 3.50%, 18.48%, 50.31%, 61.42% respectively, while those for 0.5 kJ/m^2 DUV were about 0.40%, 5.98%, 9.30%, 16.70% respectively. Palythine appears to have the ability to protect spores of P. palmata from UV radiation.
