The growth rates of
Skeletonema costatum increase with the increasing light
intensity from 20 to 45 μmol·m–2·s–1. When exceeds this
light intensity range, the growth rates gradually decrease.
The maximum and minimum growth rates of Skeletonema
costatum are 0.1953 at 20 μmol·m–2·s–1 and 0.3212
at 45 μmol·m–2·s–1, respectively. The saturated light intensity
of Skeletonema costatum under red light is about
45 μmol·m–2·s–1.
