The estimation of drought hardiness of sea buckthorn varieties of different environmental and geographical origin was made in the field and laboratory conditions. In late August the drought hardiness was estimated according to leaf injures and abscission in the field conditions. In the laboratory conditions were determined the main characteristics of water regime: tissue water saturation, water deficit, leaf water retaining ability. As a consequence, the studied varieties were divided into groups with different drought hardiness degree.

В полевых условиях была оценена устойчивость к засухе в конце августа по повреждению и осыпанию листьев. В лабораторных условиях определены основные показатели водного режима: оводненность тканей, водный дефицит, водоудерживающая способность листьев. В результате исследований изученные сорта распределены на группы с различной степенью устойчивости к засухе. | Проведена оцінка засухостійкості сортів обліпихи крушиноподібноїрізного еколого-географічного походження в польових і лабораторних умовах. У польових умовах оцінювали стійкість до засухи на кінець серпня за ушкодженням і осипанням листків. У лабораторних умовах визначали основні показники водного режиму: оводненість тканин, дефіцит води, водоутримувальну здатність листків. За результатами досліджень вивчені сорти поділили на групи за ступенем стійкості до засухи.

The article offers results of research on morphological characteristics and biological properties of blackberry, their inheritance, as well as stability and variability under the influence of agro-ecological conditions and stress factors of the environment with a view of recognizing, describing and identifying varieties undergoing official research and technical examination on DUS, which also could be used in the breeding process.

On the basis of literary sources history of origin and development of agriculture is rotined in Ancient. The first Civilizations arose up on fat streamside lands of the large rivers: Nile, Euphrates, tiger, Inda, Ganga and other Earths and plenty of water are fertile during an overflow, a warm climate allowed to Ancient civilizations to grow 2-3 harvests in a year. For the receipt of high harvests, a man had to study the modes of overflow of the rivers, look after heavenly bodies, determine the areas of scopes and terms of leadthrough of the field works. The decision of these questions resulted in the origin of agronomics, astronomy, mathematics. Large harvests were instrumental in the origin of peculiar, enriching of the states, to development of trade and culture on the whole. Riches of country and overpopulation resulted in the origin of wars which one states perished as a result of, second – blossomed. Scientists consider that a high culture, intensive exploitation of soils and aggressiveness of man, brought the most Ancient Civilizations over to the ecological crisis and their elimination.
