Virginal period. 
Grass stage - 65% of the seeds sown in fall on October 2, 2017 in an 
experimental field in Boysun district germinated on February 25, 2018. Seed leaves are 
narrowly lanceolate, 0.5 cm long and 1.2 mm wide in a 10-day-old seedling. The grass 
stage in the plant was 8-12 days. 
Juvenile stage. 
In the middle of March 12.03.2018, a 
true leaf was formed, the height of the plant was 1.2 cm. After a few days, the growth of 
the plant accelerated, the height of the plant was 2.9 cm, and the width was 2.6 mm. In 
the second ten days of March, the height of the plant reached 5 cm, the number of 
leaves reached 6, and their size was 0.4-0.5 cm. At this time, the root depth reached 9 
cm. It was observed that the height of the plant is 9-10 cm, the number of leaves reaches 
6-7, and their length is 0.7 cm and width is 0.4 cm. At this time, the sparsest joint 
spacing of the branch was 0.4 cm, and the leaf helve was 0.2-0.3 cm long. By the end of 
March (30.03.), the height of the plant reached 11-12 cm, the number of leaves reached 
8, and their size was 0.9 cm, width 0.5 cm. Thus, Ajuga turkestanica (Regel) Brig in the 
juvenile state of the plant, up to 8 leaves were formed on the stem, and this stage of 
sprout development lasted 15-20 days. 
Immature stage. 
In the first ten days of April 
(5.04), the height of the plant reaches 13 cm. The number of leaves reached 9, and their 
length was 0.6-0.7 cm. At this time, the root depth reached 22 cm. By the middle of 
April (15.04.), the growth of branches became active with the increase in air 
temperature. It was observed that the height of the plant is 19-20 cm, the number of 
leaves reaches 9-11, the length is 0.9 cm, the width is 0.4 cm. By the end of April 
(30.04.) the height of the plant was 21-25 cm. The number of leaves reached 14, and 
their length was 1.1 cm, width 0.5 cm. This stage of development of 
A. turkestanica 
Brig seedlings lasts 25-27 days. According to the observations, the third-year plant in 
the experimental field in Boysun district entered the generative period on April 25, 
2022. By this time, it was found that its height was 39-42 cm, the number of stems was 
3-4, the number of leaves was 23-31, and the depth of the root was 75-82 cm.
