摘　　要：为了探索适合长紫菜（Pyropia dentata）壳孢子的放散、附着和萌发的环境条件,为生产实践提供技术依据和参考,分别比较了不同温度（14℃,18℃,22℃,26℃）、盐度（15,20,25,30,35）和光照强度（0 lx,3 000 lx,6 000 lx,9 000 lx）对壳孢子的放散、附着及萌发的影响。结果表明,适合长紫菜壳孢子放散温度为14~26℃,盐度为25~30,光照强度为0~3 000 lx;适合壳孢子附着的温度为14~22℃,盐度为25~30,光照强度为6 000~9 000 lx;适合壳孢子萌发的温度为22~26℃,盐度为25~35,光照强度为3 000~9 000 lx。To explore the suitable environmental conditions for conchospore releasing, attachment and germination in Pyropia dentata, and to provide references for production, we compared the effects of different temperatures （ 14 ℃, 18 ℃, 22 ℃, 26 ℃ ） , salini- ties （15, 20, 25, 30, 35） and light intensities （0 Ix, 3 000 lx, 6 000 lx, 9 000 lx） on the conchospores releasing, attachment and germination. The results show that the suitable conditions for conchospores releasing were temperature of 14 - 26 ℃ , salinity of 25 ~ 30 and light intensity of 0 -3 000 Ix; the suitable conditions for conchospores attachment were temperature of 14 ~ 22 ℃, salinity of 25 ~ 30 and light intensity of 6 000 - 9 000 lx ; the suitable conditions for conchospore germination were temperature of 22 ~ 26 ℃ , salinity of 25 - 35 and light intensity of 3 000 ~ 9 000 Ix.
