The other two populations (LD64 significantlyrust, gray mold, and powdery mildew had been identified, but this does not significantly impact the population size and structure. The other two populations (LD64 and and LD6) are situated at the same altitude of 1925 m above sea level. LD6 is in Western LD6) are positioned in the exact same altitude towards the m above sea level. LD6 is in Western Altai, Altai, though population LD64 is locatedof 1925south, in the South Altai territory. On the other hand, while population LD64 is positioned for the south, the species Altai territory. Nonetheless, difdifferences in soil and climatic conditions affect in the Southcomposition of phytocenoses and, accordingly,and climatic circumstances impact the populations. The LD6 population is ferences in soil the structure of A. ledebourianum species composition of phytocenoses beneath accordingly, the structure of A. ledebourianum populations. The LD6 population is and, conditions of excessive moisture, along with the plants are scattered, mostly on hummocks. This can be largely since the soil freezes to a plus the plants are scattered, mainly oncover beneath situations of excessive moisture, depth of 35 cm before snowfall. Snow humheight can reach 150 cm through the soil freezes tosnowmelt for that reason happens only in April, mocks. This is largely due to the fact some years, in addition to a depth of 35 cm before snowfall. Snow but theheight can attain 150 cmto long stagnation of and melt watertherefore occurs only i.
