Table 5.

The extinction coefficient (K) and minimum light intensity (Imin) of some investigated plant communities. The plants on which the extinction coefficient was mainly determined are marked by *. F* = fresh weight of the photosynthetic tissue in g per 50 × 50 cm2, C = fresh weight of the non-photosynthetic tissue in g per the same area. F = leaf area index
