摘　　要：通过室内试验和数理统计的方法,研究了光棘球海胆受精卵发育的生物学零度及有效积温。试验结果表明:光棘球海胆受精卵发育的生物学零度为4.66℃;受精卵发育至棱柱幼体的有效积温为482℃.h;受精卵发育至初期稚胆的有效积温为350℃.d。The biological zero temperature and effective accumulated temperature in sea urchin Strongylocentrous nudus were determined by constant temperature experimentation in a laboratory. The results showed that the biological zero temperature for development of the sea urchin zygotes was 4.66 ℃ and the effective accumulated temperature 482 ℃· h. The effective accumulated temperature at which the zygotes will developed into early juveniles was 350 ℃· d.
