Dynamics of the demographic structure and variability of some morphological parameters of Calophaca wolgarica (Fabaceae) during reintroduction to the Saratov region
Preliminary results of studies on the reintroduction of Calophaca wolgarica to the territory of the Saratov region are presented. In the period from 2018 to 2020, the age structure of artificial plantings and changes in the morphological parameters of individuals within them were studied. It is shown that on the territory of the Saratov region, artificial plantings of this species are best located near the protected area “Tulip Steppe near the village of Maksyutovo”. They marked the transition of plants from one ontogenetic state to another, the first generative plants appeared, which gave fruit. The habitat conditions of artificial plantings near the protected area “Ivanovo Field Tract” can be assessed as satisfactory – plant growth is slower, and the number of individuals that have passed from one age state to another is insignificant. Individuals of artificial plantings of C. wolgarica on one of the terraces of the Stepan Razin cliff mostly died, the remaining ones show general stagnation and extremely insignificant growth without transition to later age states.
