Abstract

Over the past three decades, trends of climate change are becoming more expressive. For example, today the amount of heat and duration of the warm period of the year in the Volyn region corresponds to the same level of the Northern Steppe 30 years ago. There is a tendency of expansion of areas of numerous weed species, including A. artemisiifolia - Ambrosia artemisiifolia L. adventive that arrived almost a century ago. Areas of bindweed - bindweed arvensis L., kirkason normal - Aristolochia clematitis L, Molokai Tatar - Lactuca tatarica (L.) C. A. M., and others are spreading Northward. Climate change will affect cultural crops and weeds. Nowadays, plant responses to induced distresses of the most common weed species have been studied insufficiently. Previous studies of these issues show the ambiguity of physiological responses of juvenile plants, such as field mustard - Sinapis arvensis L. on induced dis-stress (mechanical damage of the aboveground parts in different phases of development). An overview of topical issues of researches on the physiological responses of weed plants to climate change and induced distresses indicates the prospects and feasibility of establishing effective system of weed control.
