The results of the study of phytotoxic effects of water extracts from Pinus sylvestris L., Betula pendula Roth, Quercus robur L., Picea abies (L.) Karst. P. excelsa Link, Carpinus betulus L., Robinia pseudoacacia L., Populus tremula L., Crataegus submollis L. are presented. For а comparison of the phytotoxic activity of the investigated plants was used to measure the change in the intensity of the mitotic division, depending on the concentration of aqueous extraction of plant material (tangent trend curve of cytostatic activity). According to this parameter, the following row of phytotoxic activity of wood species can be ordered: Populus tremula, Betula pendula, Robinia pseudoacacia, Carpinus betulus, Acer platanoides, Tilia cordata, Pinus sylvestris. Water extract Quercus robur and Picea abies have discovered a phyto-stimulating effect. The results of the study allow us to discuss the possibility of introducing the parameter of the phytotoxicity coefficient to determine the allelopathic effect in the tree-tree system.
