Calophaca wolgarica

Optimization of conditions for preserving the gene pool of endemic Calophaca wolgarica in a collection of sterile in vitro cultures

The article presents the results of the successful creation of an in vitro gene bank of Calophaca wolgarica (L. f.) Pall. ex Fisch., a rare shrub of the Fabaceae family, paleoendemic to southern Eastern Europe, comprising samples with contrasting genotypes from across the species’ range. Samples for explantation were selected based on the results of monitoring morphological variability and molecular genetic polymorphism in populations of this species.

Оптимизация условий сохранения генофонда эндемичного Calophaca wolgarica в коллекции стерильных культур in vitro

Приведены результаты успешного создания генетического банка in vitro Calophaca wolgarica (L. f.) Pall. ex Fisch., – редкого кустарника семейства Fabaceae, палеоэндемика юга Восточной Европы, представляющего собой совокупность образцов с контрастными генотипами со всего ареала этого вида. Образцы для эксплантации отобраны по результатам мониторинга морфологической изменчивости и молекулярно-генетического полиморфизма в популяциях данного вида. Эксплантирован семенной материал, собранный в 2024 г.

The Variability of Some Morphological Parameters Calophaca Wolgarica in the Populations of the Volgograd Region

It is shown that habitat conditions have a strong influence on the shape and vitality of the state of the individual Calophaca wolgarica. The most favorable conditions for the growth of Calophaca wolgarica in the Volgograd region are aligned sites with non-light-chestnut fairly rich soils in shrub-grass and couch-grass communities on the edges of the belts, on which there is no mowing and minimal grazing.

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”.
