摘要

Abstract

The light demands of seaweeds is an interesting and rather complex phenomenon because they depend not only on the species but also on their different development stages. Even different parts of the same plant sometimes have different light demands. Light control is an important procedure at large scaleLaminaria nursery stations in China. Technicians and scientists have different viewpoints on the best method to regulate light. A culture study onLaminaria japonica starting from zoospores to several centimeter sporophytes to find the optimal and critical irradiance ranges for juvenileLaminaria at different development stages added more knowledge on this aspect. Experiment results show gametophytes can not tolerate irradiance of more than 150 μE m−2s−1 while sporophytes can tolerate more than 519 μE m−2s−1. This big difference starts from the very early stage of 1-to 2-celled sporophytes. The biological basis and mechanism of this phenomenon need further research.
