supports south-southeasterly winds, however prevailing either during a limited period of leaf and fruit fall or it affected first of all the upper part of the leafy crown, thus transporting a low number of leaves and fruits to longer distances. Quadrats having the highest number of leaves and fruits are situated first of all below the leafy crown. In some of the quadrats situated in south-east, northeast direction below the leafy crown even more than 500 leaves were found, whereas in quadrats of the southwest transection situated just the same distance away from the tree trunk less than 100 leaves per quadrat were found. According to the wind direction the contour lines of leaves and fruits are shifted more to the north-northwest direction as compared to the tree trunk and the leafy crown. The contour lines of fruits (Figs 6-7) are much more distorted (to the north-northwest direction) than those of leaves. Thus, the distributions of leaves and fruits show remarkable différencies (it is also demonstrated by a comparison of distributions, Figs 11-14). The winged fruits of Acer platanoides seem to be much more sensitive to the effect of wind Figs 6-7. 6 = Contour figure of the number of Acer platanoides leaves along the transections. The bold line represents the extension of the leafy crown. Due to the south-southeasterly winds the pattern of the distributions is distorted to the north, northwest 7 = Contour figure of the number of Acer platanoides fruits along the transections. The bold line represents the extension of the leafy crown. The pattern of the distribution of fruits is more distorted to the north, northwest than that of the leaves which may be due to the joint effect of several factors
