鹿児島湾に生育する海産顕花植物アマモZostera marinaの分布南限個体群の光合成における温度や光の影響に関する論文が刊行されました。

Please take a look at our new article featuring the interactive effects of temperature and irradiance including spectral light quality on the photosynthesis of a brown alga Saccharina japonica (Laminariales) from Hokkaido, Japan. This alga is known to be found in subtidal waters up to 20m deep in Hokkaido Island. As the red light that is essential to chlorophyll-a photosynthesis is quickly absorbed in shallow waters, the light spectral availability for photosynthesis is limited in such depth. In fact, the result of the present study revealed that this alga can be well photosynthesized under blue light that penetrates into subtidal waters.
