Preservation and restoration of the biological diversity of the world's flora is an
important task in the field of nature protection. This is due
to the growing impact of
anthropogenic factors and changing climatic conditions. Medicinal plants are a category
that is especially vulnerable due to intensive, irrational procurement of raw materials.
Particularly vulnerable species are endemic and rare plant species. One of the real and
effective and long-term ways to conserve biodiversity can be the breeding of endemic
and rare species under controlled conditions. An effective approach to solving this issue
should be based on a deep knowledge of the biological characteristics and ecological
properties of endemic species.
Astragalus babatagi
-
is an endemic of Central Asia, Southern Pamir - Alai. It is
distributed mainly in the Surkhandarya region, on the slopes of northern
exposures on
gypsum-bearing variegated flowers.
The work aims to establish the distribution areas of
Astragalus babatagi
M.Pop. in
the south of Uzbekistan and study plant growth features in Tashkent.
Studies of the distribution area of the plant showed
that the species is mainly
distributed in the middle part of Mount Babatag, in the vicinity of the village. Zarkamar,
Chagam, in the tract Kyndik-kutan. The plant is rare or so scattered, single specimens,
do not form plant groups. This suggests that its harvesting is completely unprofitable.
Seeds of plants of the species
A. babatagi
for research
were collected in the
Surkhandarya region, in the middle part of the Babatag mountain (near the village of
Zarkamar) at an altitude of 1700 m above sea level. The sowing was carried out on
February 25, 2022. sulfuric acid showed that in seeds with 5 and 10
minutes of
treatment, germination was 32.8% and 34.5%, respectively, in those treated for 20
minutes - 62.3%, and in the control variant only 12.4%. Carrying out scarification had a
positive effect on the further development of plants, the appearance
of the first leaves
was observed on April 8, the beginning of the branching of rosettes on April 22, the
beginning of flowering on June 3, the fruiting stage on June 27 and the mass ripening of
fruits was completed by mid-July. In the control variant, the plants lagged in
development stages by a month did not reach the flowering stage, and by the end of July
began to die off.
The experimental accumulated material will serve as the basis for solving
the issue of
preserving these species and their successful cultivation in the future.
