The article provides data on the results of monitoring rare and endangered vascular plants in the Biosphere Reserve “Lower Prut”, in the southwestern part of the Republic of Moldova. The new information on the presence of five rare species (Schoenoplectiella supina (L.) Lye, Cyperus odoratus subsp. transcaucasicus (Kük.) Kükkonen, Valerianella pumila (L.) DC., Valerianella turgida (Steven) Betcke and Veronica scutellata L.), bioecological, distributional, sozological and some populational features are presented. Schoenoplectiella supina is listed and collected for the southwestern region for the first time.

In provenance cultures, studies were conducted on diameter growth dynamics in pedunculated oak (Quercus robur L.) trees and the height-diameter relationship was evaluated based on three data approximation models. The studies highlighted a signifi cant variation of the trunk diameter in trees of different origins and a similar growth reaction of oaks from four provenances (Hârjauca, Plaiul Fagului, Zloti, and Baimaclia) in relation to the environmental conditions of the common stand. In all the years of observation, the trees from Edineț had a rapid growth in diameter, thus demonstrating their ability to adapt through phenotypic plasticity. An uneven distribution of tree diameters was observed by provenance, indicating that dominant trees have an advantage in competition for light, slowing the growth of those with smaller diameters and causing a positive skew towards oaks with larger diameters. With the advancing age of the oaks, a tendency to decrease the values of the heritability coefficients for the trunk diameter was observed. At the age of 5 years, studies show a strong genetic control over the growth in diameter, a fact highlighted by the heritability coefficient value of 0,53 for this character. As the trees age, non-genetic factors such as environmental conditions become increasingly important in determining tree diameter growth. The comparative analysis of three statistical fitting models for data on pedunculate oak trees from different provenances, showed that the logarithmic model is the most appropriate to explain the relationship between their height and diameter.

A review is made of the work carried out over the course of 50 years in creating the „Vegetation of Moldova” Exhibition at the National Botanical Garden „Alexandru Ciubotaru”. From the initial plantings in 1972 until the year 2023, design, planting, and mobilization of the gene pool have been undertaken. Currently, the Moldavian present Vegetation Exhibition includes 12 micro-exhibitions of forest vegetation, 2 micro-exhibitions of meadow vegetation, 1 micro-exhibition of steppe vegetation, and 1 microexhibition of aquatic and marsh vegetation. In 2020, the exhibition area was settled, parcel divisions were elaborated, boundary markers were installed, and borders were delineated. The article presents the results of inventorying trees, tree seedlings, shrubs, and herbs for each micro-exhibition and sub-plot. Flora of the „Vegetation of Moldova” Exhibition at the National Botanical Garden „Alexandru Ciubotaru” includes 560 species of vascular plants, of which 258 species grow in 12 forest micro-exhibitions, 152 species grow in the micro-exhibition with steppe vegetation and 150 species of plants grow in meadows vegetation. For each sub-plot within the forest micro-exhibitions, data is provided on the number of specimens for each tree species, the composition of the shrub layer, and the herb layer. 61 species of rare plants are preserved ex situ, in the „Vegetation of Moldova” Exhibition in the Botanical Garden „Alexandru Ciubotaru”, of which 32 species are included in the Red Book of the Republic of Moldova.

In the comparative forest cultures of the "Plaiul Fagului” Scientific Reserve, an evaluation of the chlorophyll index and dry mass in the leaves of pedunculate oak descendants from the northern, central, and southern regions of the Republic of Moldova was carried out. The obtained data showed significant variations within trees in terms of minimum and maximum values, as well as the position of the median value relative to the mean in the distribution of the chlorophyll index in the investigated provenances. The analysis of the variation indicates significant differences in the distribution of the chlorophyll index of the leaves of trees originating from different ecological zones. Within this variation, two trends can be observed. The first trend refers to the fact that descendants from more distant areas (in the north and south) have a higher chlorophyll index than those from the central area (including local provenance). This difference due to the fact that descendants from ,,foreign” zones are exposed to different environmental conditions than optimal ones, which makes adaptation processes more pronounced compared to descendants from the central zone with similar conditions to the cultivation area. The second tendency consists of the uniformity in the response of different genotypes of non-locally provenance descendants from remote areas in the north and south, in relation to the specific environmental conditions of the common arboretum. This uniformity is indicated by lower coefficients of variation in the chlorophyll index of descendants from ,,foreign” zones compared to local provenance ones. Therefore, descendants of non-local provenance developed adaptation processes in new environmental conditions reflected by differences in the distribution of chlorophyll content. In descendants of northern and southern origin, these differences are lower than those characteristic of local provenance descendants. This view is supported by the fact that the dry mass rate of the leaves of local provenance descendants tends to be lower compared to those from the northern and southern parts of the Republic of Moldova.

For the first time, the phytocoenological study of the populations of the critically endangered species [Critically Endangered (CR)], included in the Red Book of the Republic of Moldova, Centaurea thirkei Sch.Bip, was carried out from the Forest Reserve “Hîrtopul Moisei”. As a result of the phytocoenological research carried out in the reserve, out of the 13 geobotanical reliefs made, only 2 of them could be grouped at the association level (in Iridio variegatae-Quercetum pubescentis Pînzaru, Cantemir et Belous 2022), the others remain to be described at the level of phytocoenoses, not reaching the required number of descriptions to be grouped into associations. The population study included the estimation of population characteristics, such as: the population (number of individuals), their density, age composition, dimensional structure, etc. We propose expanding the area of the reservation by including plot no. 15 which contains natural sectors with Q. pubescens and small groups of Centaurea thirkei Sch.Bip.
