摘　　要：1AA 3-Indolylacetic acid, NAA a-Naphthylacetic acid and cytokinins in PESI culture medium were used in a study on the effects of plant hormones on the growth of free-living conchocelis of Porphyra yezoensis which showed that its growth in medium with cytokinins, 1AA and NAA was more rapid than that in medium with non-phytohormones; that the optimal concentrations for promoting growth were 10μg/L for IAA and ZA (Zeatin), and 0.1 μg/L for BA 6-Benzyl amino purine and KIN 6-Furfurylamino- purine. Mix use of NAA, 1AA and cytokinins, NAA/ZA 1-1000/1μg/L, NAA/BA 10/1-1000 μg/L, NAA/KIN 1/1-1000 μg/L promoted growth. 1AA/ZA 0.1-1/0.1-1μg/L; 1AA/BA 0.1-1/0.1-10 μg/L IAA/KIN 1/0.1-1000μg/L also promoted growth.IAA 3-Indolylaceic acid, NAA a-Naphthylacetic acid and Cytokinins in PESI culture mediumwere used in a study on the effects of plant hormones on the growth of free-living conchocelis ofPorphyra yezoensis which showed that its growth in medium with cytokinins, IAA and NAA was morerapid than that in medium with non-phytohormones, that the optimal concentrations for promotinggrowth were 10μg/L for IAA and ZA (Zeatin), and 0.1 μg/L for BA 6-Benzyl amino purine and KIN6-Furfurylamino- purine.
