Oker-Blom, P. and Kellom~iki, S., 1982. Effect of angular distribution of foliage on light absorption and photosynthesis in the plant canopy: theoretical computations. Agric. Meteorol., 26: 105--116.
Light absorption and photosynthesis, as affected by the angular distribution of leaves and needles were studied mainly on the basis of theoretical computations. It was apparent that the mean flux density of the light falling on the foliage during the growing period, April 15--October 15, was only slightly affected by the inclination of the foliage as far as O , . , northern latitudes (60 N) are concerned. Photosynthesis m horizontal leaves was found to be greater than that in vertical ones when lower values of leaf area index (~2) were evaluated during June 15 and August 15. In the case of larger values of leaf area index (~6), vertical leaves were somewhat more effective than horizontal leaves in June, but in August the result was quite the opposite. At northern latitudes (~>60°N) the efficiency of vertically inclined foliage seems to be greater only during a rather short period around midsummer.
