Abstract

The annual ring width of three 85-120-year-old Quercus cerris trees, three 105-116-year-old Betula platyphylla trees, one 91-year-old Carpinus betulus tree, three 172-183-year-old Larix sibirica trees, and three 135-208-year-old Pinus silvestris trees originating from different sites (Hungary, Mongolia) was compared with cycles of sunspot activity. The effect of sunspot activity on the annual ring formation process of the tree species examined was not unequivocally provable.
