摘　　要：报道了生态因子对条斑紫菜自由丝状体生长的影响，结果表明，条斑紫菜自由丝状体生长的最适宜盐度范围为２０～３０，低于１０的盐度不能生长，最适宜温度范围为１５℃～２５℃，高限为３０℃，适宜光辐照度１５μＥｍ－２Ｓ－１～６０μＥｍ－２Ｓ－１。添加的适宜Ｎ浓度２０ｇ／ｍ３～６０ｇ／ｍ３，Ｐ为１５ｇ／ｍ３～５ｇ／ｍ３。This paper introduced the experimental ecological tests of growth of freeliving conchocelis of Porphyra yezoensis Ueda indoor in ZhejiangThe effects of ecological factors,such as temperature,irradiance,salinity were discussedThe results observed were that the optimal salinity was 2030,it cant grow below salinity of 10The suitable temperature was 1525,the high line was 30The optimum of irradiance was 15Em-2S-160Em-2S-1The optimum supplement concentration to medium was 20g/m360g/m3 of nitrogenous and 15g/m35g/m3 of phosphate
