Results above show that when cells are exposed to blue,
green or red light, the growth conditions of Skeletonema
costatum are greatly influence by different light wavelength.
For three kinds of monochromatic light, the growth
rates of Skeletonema costatum are significantly different.
The growth rate under blue light is larger than under green
and red light until it reaches saturation light intensity. In
blue light condition, the saturation light intensity is about
40 μmol·m–2·s–1, which below the value of saturation
light intensity of the green (50 μmol·m–2·s–1) and red light
(45 μmol·m–2·s–1)
