In order to understand the influence of UV-B radiation on the young sporophytes of Laminaria japonica,we tested the growth and physiology of the young sporophytes under three different doses of UV-B radiation(11.

The impacts of temperature on growth and photosynthesis of Laminaria japonica juvenile sporophytes;

I n this paper,Photosynthesis properties of female and male gametophytes as well as juvenile sporophytes of Undariap innatifida were investigated.

The effects of attachment and growth of kelp spores on the surface of various anionic, cationic and nonionic hydrogels were studied.

Experiments in this study on the effect of water temperature upon the development of pelagospheric larvae of peanut worm Sipunculus nudus were conducted over larvae from swimming period to setting stage,in which,parents worms used for larvae-producing were collected from native sea waters,and larvae were obtained by man-made induction to spawning and hatching.
