Paper Abstract

In the given work the results of research of concentration dependence of fluorescence for leaves of a birch are resulted. The change of parameter F682/F734 in process of vegetation is described by two parabolas. One parabola describes the period when the increase of chlorophylls concentration to the maximal meaning is observed, and second-period of aging of a leaf. The minimum of the first parabola is observed at chlorophyll concentration in leaves during flowering of a birch, and second - before the beginning of leaves colouring. The indexes, which reflect potential photosynthetic activity in two lengths of waves - 682 and 734 nm, are most informative parameters of red and far-red fluorescence of leaves of a birch and an early harbinger of morphological changes leaves of trees.
