摘要

The large life cycle Rhaponticum integrifolium in natural populations (Qashqadaryo, Uzbekistan) was studied. Duration of before generative, generative and senile periods of Rhaponticum integrifolium is 2 - 5, 8 - 10 and 2 - 4 years respectively. The beginning of phenophases depends on the height of the terrain above sea level: raising the terrain from 400 to 1500 m leads to a delay in the onset of phenophases. Age states of Rhaponticum integrifolium in different ecological and phytogenetic conditions were revealed. Updated distribution of detected participation of vegetation and the raw Rhaponticum integrifolium in Uzbekistan, describes the dynamics of the contents ecdysteroids in the periods of vegetation. At the same time, a map of the species area in Central Asia was made and the term of its phytomass recovery under different operating modes of thickets was determined.
