DuchovskisSummaryThe aim of work was to present ecophysiological investigations under conditions ofchanging environment carried out at the Laboratory of Plant Physiology, LIH. From 2000 till2008 laboratory with such institutions as Vytautas Magnus University, Lithuanian University ofAgriculture, Lithuanian Forest Research Institute, Lithuanian Institute of Agriculture, Instituteof Botany, Institute of Chemistry and Institute of Geology and Geography participated in theseprojects, which were supported by Lithuanian State Science and Studies Foundation: “Integratedinfluence of natural and anthropogenic factors on plants in the level of different individualsand populations”, “Integrated influence of anthropogenic, climate and environment changeson the forest and agro-ecosystem vegetation”, “Physiological and biochemical response ofwoody plants to natural and anthropogenic stressors” and “Productivity and stability of agroecosystems under climate change”. During investigations were obtained important results aboutresistance, adaptivity and competitive ability of various plants under effect of complex naturaland anthropogenic factors. Data of investigations were published in scientific publications,present in international scientific conferences. It was defended PhD thesis.Key words: abiotic stress, growth, ecophysiology, productivity.276
