Биоэкологические особенности и перспективы использования некоторых видов рода Juglans L. в качестве компонента антропогенных насаждений

Abstract

For the low-forest Samara region, where representatives of the Juglandaceae DC ex Perleb.do not exist in natural ecosystems, a study of their introductory prospects is characterized by the great practical and theoretical importance. At present, the following species of the Juglans genus are preserved in the collection of the Botanical Garden: J. ailanthifolia Carr., J. ailanthifolia f. cordiformis (Maxim.) Rehd .; J. cinerea L.; J. mandshurika Maxim., J. microcarpa Berland. J. nigra L., J. regia L., and J. regia f. fertilis Petz et Kirch., which are represented by trees of 1–3 generations of local generation). The article presents information about the features of their resistance in relation to droughts and extremely frosty winters. Peculiarities of phenology, fruiting, allelopathic activity of litter, as well as perspectives of independent introduction into the natural communities of the region, are also considered.
