Observations on the ontogeny of 
A. turkestanica 
(Regel) Brig. were carried out in an 
experimental field in Boysun district. We divided the growth and development of the 
plant into latent, virginal and generative periods. The virginal period, in turn, was 
divided into three stages: grass, juvenile, immature. 
Latent period. 
The seeds of 
A. 
turkestanica
ripen in early July. The fruit is 4, nutlet form, dry, unopened, bean, covered 
with 20-30 toothed fluffs. In the seed, the endosperm is developed, the ridge is located 
correctly. Seed germinability is preserved for up to 5 years. To determine this issue, we 
conducted experiments in laboratory conditions during the years 2018-2022 to 
determine the germination of seeds stored for different periods of time and at different 
temperatures. Seeds stored in laboratory conditions at 20-22°C for 1 year had a 
maximum germinability of 71.3%, and after 5 years, this indicator decreased three times 
to 21.2%. The average value of the germinability of freshly harvested seeds in 
laboratory and field conditions during 2018-2022 was 67.7±41.7 and 33.4±3.2. The 
favorable temperature for seed germination was 20-22°С, and the germination rate was 
58.8±3.3%. Thus, the level of germination was high at a temperature of 20-22°С.
