Endl. were investigated by using the point quadrat method. Long needles, or point quadrats, were placed vertically through the seedling canopy. The leaves were clumped in layers excluding the uppermost layer where they were distributed at random. the proportion of quadrats making no contacts to the total number of quadrats can be considered to correspond to the proportion of light penetrating through the canopy, on the supposition that the sunlight ray is vertically incident on the canopy and its diffusion and transmission by leaves are ignored. The proprotion p(z) decreased with the mean number of increasing contacts per quadrat f(z) from the canopy surface down to a depth z, which followed an exponential function, viz. p(z) = exp(\uff0dk\uff65f(z)). The constant k was estimated to be 0.47 in November 1981, 0.54 in June, and 0.61 in September 1982.
