ONTOGENY OF SOME MEDICINAL PLANTS IN THE CONDITIONS OF THE CITY OF BUKHARA

For the first time, the growth, development and ontogenesis of some medicinal plants from the Asteraceae family – Silybum marianum (L.), Cota altissima (L.) J. Gay; Fabaceae family – Cassia tora L. in the soil and climatic conditions of Bukhara were studied. The germination of seeds in laboratory and field conditions was determined. The seeds were sown in autumn (in November). Autumn crops in the first year of vegetation reached the generative period of ontogenesis (bloomed and bore fruit). All the above-mentioned species studied adapt well in unfavorable soil and climatic conditions of Bukhara.
