“…Hence, the introduced coenopopulation of C. reticulatus from the NBG is completely framed within these wide ranges. The natural population of C. reticulatus with the similar small area, number, and average density of individuals was reported from Voronezh region (Shilova et al, 2019). However, if compared with original natural populations from the Kyiv Plateau and Donetsk Upland, the introduced coenopopulation at the NBG is characterized by significantly lower area, number, and average density of individuals (Table 1).…”

“…The parameters of the introduced coenopopulation of C. reticulatus were compared with the corresponding parameters of the natural populations of this species. Natural populations of C. reticulatus are characterized by wide ranges of the covering area (from thousands of a hectare up to dozens of hectares), the number of individuals (from tens to hundreds of thousands of individuals), and the average density of individuals (from 0.1 to tens of individuals per 1 m 2 ) (Gritsenko, 2004;Peregrym, 2004;Korotchenko & Peregrym, 2009;Shynder, 2009Shynder, , 2010Melnyk et al, 2010;Shilova et al, 2019;Cherniavskih & Glubscheva, 2020;Vladimirov et al, 2020).

The research was carried out during Crocus reticulatus flowering time in 2002–2020 at the botanical-geographical plot “Steppes of Ukraine” of the M.M. Gryshko National Botanical Garden, National Academy of Sciences of Ukraine (NBG). Crocus reticulatus was introduced to the NBG from the natural habitats in 2002–2003. Ten generative individuals were planted in an area of 2 m2. The area of coenopopulation and the number of individuals increased gradually until 2018. In 2019–2020, there was a rapid increase in the covered area and number of individuals. However, the average density of individuals decreased. The percentage of pregenerative plants (juvenile, immature, and virginal) increased, and the percentage of generative individuals decreased. As of 2020, the area of introduced coenopopulation of C. reticulatus at the NBG reached 195 m2. It consists of 175 individuals (38 juvenile, 21 immature, 23 virginal, and 93 generative). The average density is 0.9 individuals per 1 m2. The spatial distribution of individuals is characterized as random and in groups. This is due to the predominance of the myrmecochoric and barochoric propagation. Indicators of the area, number, and average density of the introduced coenopopulation are within the normal ranges of the natural populations; however, they are smaller than those in maternal populations. The number of individuals of different age states and the number of individuals with one and two or three flowers in the introduced coenopopulation is close to such parameters of the natural population from Kyiv Plateau. Flowers of different colors were observed both in the introduced coenopopulation and in natural populations of C. reticulatus. As of 2020, the introduced coenopopulation of C. reticulatus is in the phase of logistic growth.

“…The fraction of hard seeds in the seed material of G. uralensis can reach 70-90 % [5,9]. To significantly increase the laboratory and field germination of the seeds, various methods were used, including scarification of seeds with sandpaper, serial immersions of seeds in boiling and cold water, and treatment with concentrated sulfuric acid [4,10,11]. But agronomic practice is needed to further searching for optimal variants of pre-sowing treatment of licorice seeds.…”

Development of new methods for increasing the germination of licorice (Glycyrrhiza uralensis Fisch.) seeds: preliminary data

2020

The licorice (Glycyrrhiza uralensis Fisch.) is cultivated as a valuable medicinal plant. It is grown from seeds, but 70-90% of its seeds are in deep physical dormancy (hard seeds) – do not swell and do not germinate without special treatment (scarification). We are searching for the most effective methods of such processing. We have studied the effect of hydrostatic pressure from 10 to 40 MPa (pressure treatment) on the licorice seeds to improve the swelling and germination of them, which belong to a pair of visually distinguished groups by the color of the seed coat. For the first time, it was found that olive-colored seeds do not germinate after pressure treatment (the number of hard seeds is 80% or more). At the same time, very high content (up to 90%) of swollen but non-viable seeds was detected in the group with a light brown color of the seed coat. Hydrostatic pressure levels used did not significantly reduce hard seeds proportion in studied licorice seed material. A weak positive effect of hydrostatic pressure treatment was found. Further search for optimal pressure treatment modes for licorice seeds germination increasing looks promising.
