The way of measurement of dynamics of growth of leaves of a tree from the beginning of blooming of kidneys until the end of the vegetative period includes such actions. The chosen leaf do not cut off, and mark with a label in the form of the label with number on the white thread adhered to the base by the petiole. Each sheet is measured. Therefore the way of measurement is individual, and revealing of laws - group on not less than 10 leaves allocated for surfaces of a crone of a tree with one light exposure. At th...

Wave equations for the dynamics of the ontogeny of linden leaves growing near a highway with intensive movement are given. The way of the analysis of parameters (lengths, width, perimeter and the area) for engineering biology and bioindication of the surrounding air environment is shown by oscillatory indignations of leaves. On the roadside, choose a tree and measure the distance from the middle of the root neck to the curb perpendicular to the road. In each zone a group of not less than 5 leaves is selected, mark...
