Background: Parasitic nematodes are very destructive to crops, ornamental plants and woody plants as well which cause most severe diseases in plants and feed on the roots of these plants.Objective: Main aim of this study is to identify different species o... see more

Water deficiency is one of the most important abiotic factors limiting the growth and productivity of plants. Under conditions of water deficiency, plants can synthesize osmoprotectors, in particular proline. The aim of our work was to estimate the accumu... see more

Soil salinization is an important abiotic factor negatively affecting plant growth, development and productivity. Fast-growing poplar and willow trees are important plants for bioenergy production demonstrating varying degrees of adaptation to differ... see more

The paper shows the results of monitoring studies of leafminer moth distribution on poplar trees in Kiev in 2012-2013. Trophic preferences of leafminer moth are determined depending on the damage degree of poplar leaves. Trophic polyphenism of leafminer m... see more

In the face of global climate changes, studies of bud burst and bud set phenology in trees are necessary to determine the duration of the growing season of plants, the optimal planting period, and seasonal works to achieve high productivity. The purpose o... see more

The study presents the results of chemical composition and microbiological activity of chloroform extract obtained from vegetative buds of Italian poplar (Populus nigra var. italica Du Roi). The content of lipophilic substances are extracted by chloroform... see more
