Отражательная способность листовой поверхности как оценочная характеристика адаптивности интродуцентов

Abstract

The reflective capacity of the bottom and top lamina surface was evaluated for invasive plants of the Rosaceae family in conditions of the Botanic Garden at the Samara University. The assessment was carried out for the following species: Armeniaca vulgaris Lam., A. sibirica (L.) Lam., Cerasus fruticosa (Pall.) Woronow, C. mahaleb (L.) Mill., C. sachalinensis Fr. Schidt Kom., C. japonica (Thunb.) Loisel., Amygdalus ledebouriana Schlecht., Amygdalus nana × Amygdalus persica Hort., Prunus divaricata Ledeb., Prinsepia sinensis (Oliv.) Oliv. ex Bean, Padus virginiana (L.) Mill., P. grayana Schneid., P. serotina (Ehrh.) Borkh., and Padus avium Mill. Analysis of leafs reflective capacity at wavelengths values of 660 and 430 nm during the 2016 vegetative season is carried out in the paper. The effect of the Botanic Garden habitat and natural biotopes of the Krasnosamarskiy Forest on the lamina reflection value is considered. The reflective capacity values typical of the studied species are presented.
