2006
Т. І. Yusypiva
Histological characteristics of a stem’s central cylinder of introduced species Fraxinus lanceolata Borkh. and F. pennsylvanica Marsh., and aboriginal species F. excelsior L. under emissions of by-product coke plants are described. Phytotoxicants cause changes in proportions of histological elements of the stele: the timber and soft bast thickness increase in the F. excelsior , the timber and medulla thickness developing, but the soft bast decreasing in the F. lanceolata, and the decrease of timber and hard bast in the F. pennsylvanica.
