Abstract.The article considers the condition of formed from Ligustraim vulgare L. seedlings L. seedlings plantings in the Saratov region, the definitions of their survival rate are given with the help of annual increments. The research topic is relevant due to the fact that there are a lot of saline soils in the region (in the Left Bank) or partially saline (in the Right Bank). This factor negatively affects the growth of green plantations, including shrubs. The novelty of the study lies in the shrub Ligustraim vulgare L. seedlings L. seedlings growth dynamics on saline soils analysis. The material was taken from a mother bush in Saratov, which grew in an aggressive urban environment. The seedlings were planted in the open ground in the Dergachi village, Saratov region. The introduction was evaluated, which amounted to more than 100 points, and the average germination rate of 83% of the total was established. It was revealed that in the second year the seedlings successfully grew, and 76% of the total planted material developed. It was found that seedlings did not sprout or did not develop well from seeds purchased in the store. Collected from the mother shrub seeds successfully germinated and were planted at the end of April in the open ground. The annual increase in height in seedlings of the second year increased 2-7 times, the number of leaflets in 75% increased three times, and in single specimens five times. The maximum number of branches and foliage was revealed in the second year Ligustraim vulgare L. seedlings L. A method of growing Ligustraim vulgare L. seedlings Ligustraim vulgare L. is proposed in soil salinization conditions, which is suitable for quickly obtaining the planting material from a growing in an urban environment mother shrub, resistant to its aggressive conditions. This makes it likely that the planting material will adapt immediately and will be in demand for the various types of plantings forming in the Saratov region.
