• 論文の詳細を見る

• Positive phototropism in the thallus of the marine coenocytic green alga Bryopsis plumosa was investigated in terms of the mode of bending, the photosensitive zone and the effectiveness spectrum. The bending occurred as a consequence of a difference in growth rate between the illuminated and the shaded sides of the thallus. Elongation on the shaded side was stimulated while that on the illuminated side was inhibited. However, the overall elongation rate was barely affected. Illumination with a fine beam revealed that a zone from approximately 80 to 120 μm below the tip was the most photosensitive. The effectiveness spectrum showed that blue light ( < 550 nm) was most effective, with light at 467 nm having maximal effectiveness.
