“…Flower clusters of different shapes were observed on the species we studied: sparse, simple cluster In subsequent years, flowering and fruiting are passed on to the part that was the growth zone of the previous year. Single clusters and short branches form in the second year in place of the flower group formed in the first year in the first main axis zone [1,8,9,14]. The initial bush grows monopodially; in parallel, axillary shoots increase and form.…”

Recently, climate change, reduction of species diversity, and food problems are among the problems that worry the whole world. Plants play an important role in solving these problems. For this purpose, we introduce various food, medical, and industrial plants. One of the plants with different fields of application is the species belonging to the genus Berberis L. For this purpose, the bioecology of Berberis L. species was studied to regulate the ecological balance. To study the introduction and adaptation of Berberis L. species to the Absheron conditions on a scientific basis, it is important to evaluate the biological and morphological features of these species at individual stages of development.During the introduction of barberry species, it is a very important issue to study the biology of individual development of each species. Ontogeny - the individual development of the species - covers the period from the zygote to the natural death of the species. Information about the morphological characteristics of the species is obtained in the developmental stages of ontogenesis.

“…In Finland, 10 variations of corolla coloration were observed in invasive populations (Table 3 and Figure 3). In Russian invasive populations, individuals are represented only by three color forms: violet, pink, and white in the ratio 23:16:7 [22]. In the Veps forest, only the form with the violet corolla is naturalized.…”

Initial Stage of Formation of Spontaneous Invasive Populations of Garden Lupine (Lupinus polyphyllus Lindl.) at the Northern Limit of Its Secondary Distribution Range in the Veps Forest Nature Park

et al. 2022

A weed plant of the species Lupinus polyphyllus was found in settlements located on the territory of the natural park “Vepssky forest” of the Leningrad region. The plant is known as a transforming species in the southern regions of Russia. The distribution of L. polyphyllus within the Vepsian forest occurs not due to the migration of the species to the north along transport routes, as one might assume, but due to flight from gardens and the formation of spontaneous invasive populations. The goal of the study was to identify the molecular and biochemical characteristics of garden lupine at the northern borders of its secondary range. To interpret the obtained data, the task of the study also included a comparison of intraspecific variability between the “old” invasive populations (in Finland and Central Russia, studied by us earlier) and the “new” naturalizing population of L. polyphyllus in the Vepsian forest. The search for L. polyphyllus localities in the territory of the Vepssky Les natural park was carried out by the route method with geobotanical descriptions of experimental sites (5 m × 5 m). DNA was isolated from eight herbarium specimens of L. polyphyllus (MHA, LE) and fifteen specimens collected in the territory of the natural park “Vepssky Les”. To reveal the internal structure and phylogenetic relationships in lupine populations, networks of nuclear and chloroplast haplotypes and cluster analysis (UPGMA) with the SplitsTree program were used. The total content of polyphenols and flavonoids in the leaves was determined spectrophotometrically. The low inter-locality variability of ITS indicates that the populations of L. polyphyllus in Central Russia and in the North of Russia (St. Petersburg and Vepsskaya Pushcha) have the same origin. Analysis of the chloroplast intergenic spacer (rpl32–trnL) indicates intrapopulation diversity and suggests the presence of microevolutionary processes near the northern limits of the secondary distribution range of L. polyphyllus. The high content of polyphenols and flavonoids in the leaves reveals the adaptive capabilities of lupine in the studied area. Evidence suggests that a neglected species may soon become invasive, as has already happened in other regions.

“…The long-established cultivation of species which have now become invasive indicates that they have valuable properties. We have collected data on the medicinal, melliferous, food, silage, and fodder benefits offered by invasive species, summarizing the global experience of using invasive alien plants [ 205 , 206 ]. Our findings suggest collecting invasive species in wild-growing invasive populations (not cultivated ones!)…”

This paper represents a review of comprehensive research into invasion biology done by Russian scholars for four decades. Invasion biology is a relatively new field of research focused on the study of alien plants, their behavior in new habitats and risks they pose to indigenous species. It is shown that over 40 years, single finds of alien plant species have transformed into a check-list of invasive species in Russia. The most significant invasion pathways were identified, and the rate of microevolutional changes in plant species in their secondary distribution range was determined. Since the most active alien species disperse without regard to national borders, international cooperation is crucial in joint studies of invasive species.
