Seedlings of Cinnamomum camphora L. were experimentally grown under different levels of light intensity including lower intensity below the compensation point, and their growth were pursued with time. The relationship between mean leaf area(u) and relative illuminance(f) was shown by the similar equation to the relationship between mean plant weight(w) and relative illuminance(f). The response curves of relative growth rate (RGR), net assimilation rate (NAR) and leaf area ratio (LAR) to common logarithm of relative illuminance were derived from the equations for u-f relation and w-f relation. The obtained curves approximately showed the change of experimental values of RGR, NAR and LAR to common logarithm of relative illuminance. The results are different from that of BLACKMAN & WILSON (1951b). The response of NAR or LAR to common logarithm of relative illuminance was not shown by a linear line. Until the sixth harvesting, the curve of NAR to common logarithm of relative illuminance showed a sigmoid curve, and LAR showed an optimum curve with a maximum value of LAR.
