Askerova, L. (Azerbaijan State Agrarian University)
The environmental factors of the places of natural growth of 4 species of rhizome irises were evaluated. The method of amplitude scales of D. Tsyganov was used, the coefficient of environmental efficiency for each factor was calculated, and the index of tolerance was determined by the method of L. Zhukova. According to climatic scales: 3 species of irises are stenobionts, and 1 species (Iris acutiloba C. A. Mey.) is hemistenobiont. According to soil scales: 2 species (Iris carthaliniae Fomin, I. paradoxa Steven) — stenobionts, 2 species (Iris imbricata Lindl., I. acutiloba C. A. Mey.) — hemistenobionts. On a scale of illumination: 3 species — mesobionts, 1 species (Iris imbricata Lindl.) — hemieurybiont. As a result of the work, it was revealed that most species belong to the stenovalent fraction.
