Abstract
Abstract The authors consider Carthamus tinctorius L. development and productivity under the influence of geographical zone conditions defining that plant vigor and reproductive sphere development are greatly influenced by climatic and ecological conditions starting from the virgin stage. A reduction in the duration of plant vegetation period in the conditions of Voronezh Oblast as an adaptation mechanism of the species was established. At the same time, the seed productivity of safflower did not depend much on geographical conditions. The authors present the results of studying the morphogenetic characteristics of species and starting date of each phenophase. The data obtained show the presence of high adaptive potential of the crop under study and the possibility of its cultivation in the conditions of the Central Chernozem Region
