Mean speed of crossing in black and transparent tubes. The mean speed increased significantly in the transparent tube according to a light intensity-dependent relationship but remained constant in the black tube. a1,b1– significant differences for the mean speed in the transparent tube between light treatments; ***—significant differences (p < 0.001) for the mean speed of crossing between the black tube and the transparent tube. The mean speed of crossing was significantly higher through the transparent tube compared to the black tube in the 20 lx and the 51.5 lx treatments. Sb = mean speed in the black tube; St = mean speed in the transparent tube.
