摘要
盐度对条斑紫菜体细胞的生长发育有明显的影响。盐度在19.6—32.8‰之间,体细胞生长发育正常;但超过32.8或低于19.6‰,体细胞成活率均下降,发育速度明显减慢。适当剂量的紫外线能促进体细胞苗生长,且可提高体细胞后代对高盐度和低盐度的忍耐力,同时获得少量能在低盐度下生长的变异体。刚酶解出的体细胞在高盐度下培养1天,然后逐渐降低盐度,可获得较高的成活率。
The growth and development of somatic cells isolated from thalli ofPorphyra yezoensis Ueda were affected greatly by salinity The growth and developmentof offspring were fast, culturing between the salinity from 19.6 to 32.8‰, but theirgrowth rate and development speed became slower, culturing at higher over 32.8‰ orlower to 19.6‰, The higher survival rate of somatic cells was obtained when they werecultured at 45.8‰ for one day. A few of variants which grow fast and having normalcolor were obtained when they were cultured at lower salinity after being irradiated byUV.
