SUMMARYMedicinal and aromatic plants are expressed by roots, rhizomes, leaves, flowers or fruitsand the scientific interest for natural medicine and traditional practice of treatment increasemore and more.The purpose of research are related with the theor... see more

We examined the vital condition of the common oak (Quercus robur L.) in plantations of different categories in Dnipro-city. In the investigated plantations, differences in the individual resistance of plants were recorded. The patterns of changes in the p... see more

Aim of the study: to analyze, within a Pinus contorta plantation, the effects of artificially created small rectangular and small medium circular canopy gaps on: i) photosynthetic active radiation (PAR), and soil temperature and moisture, and ii) survival... see more

Preparations for protecting plants, particularly those with fungicidal activity, continue to be relevant in agricultural production. They are used to effectively combat phytopathogens and ensure high yield of cultivated plants. However, they are among the... see more

A distinctive feature of legumes is the ability to combine two most important processes: photosynthesis and nitrogen fixation. However, the course of those processes, and therefore seed potential of those crops depend on a number of biotic and abiotic fac... see more
