Resumen
Hedysarum alpinum L. var. americanum Michx. (American hedysarum) is indigenous to parts of Saskatchewan. Plants grown from seeds collected at five locations in central Saskatchewan were transplanted into a nursery at Saskatoon, Saskatchewan and a study of the nutritive value of individual plants was undertaken to determine the potential value of American hedysarum as a forage legume for the northern Canadian prairies. Leaves and stems (analyzed separately) showed marked differences in chemical composition. However, they did not differ in the in vitro organic matter digestibility (OMD). American hedysarum plants had a much higher tannin content than alfalfa or birdsfoot trefoil plants grown at the same location. This may account for the relatively low OMD of this species. The protein and fiber fractions (of H. alpinum) compared favorably with those of alfalfa. Improvement by breeding for reduced tannin content would be necessary before American hedysarum would be acceptable as a forage crop.Key words: Hedysarum alpinum L. var. americanum Michx., American hedysarum, forage, tannin, in vitro digestibility, early growth

Resumen
At the moment, a relevant objective in pharmacognosy, is the use of all kinds of the DNA analysis methods for identifying plant materials, detecting counterfeits, genetically modified crops and products.The aim of the research is to study the possibility of using molecular genetic research methods in the analysis of the genus Hedysarum L., for the identification of medicinal plant materials. This article presents the results of the application of molecular genetic research methods in the analysis of the genus Hedysarum L. in the flora of the North Caucasus.Materials and methods. The study material was the samples of the genus Hedysarum L. species collected in the North Caucasus: Hedysarum caucasicum M. Bieb. (in the fruiting phase in the territory of the Karachay-Cherkess Republic); Hedysarum grandiflorum Pall. (in the fruiting phase in the Volgograd region); Hedysarum daghestanicum Rupr. ex Boiss. (in the flowering phase in the Republic of Dagestan). Sequencing of the ITS1-5.8S-ITS2 marker region of gene 5.8S by the RNA ribosome was carried out according to the Sanger method on the AbiPrism 3130 genetic analyzer at the laboratory of biosystematics and cytology of Komarov Botanical Institute of the Russian Academy of Sciences.Results. Based on a comparative study of the marker region of the nuclear ribosomal gene 5.8S rRNA, marker nucleotide substitutions of Hedysarum caucasicum M. Bieb., Hedysarum daghestanicum Rupr. ex Boiss., Hedysarum grandiflorum Pall, have been identified. The most probable secondary structure of 5.8S rRNA has been constructed. It has been shown that based on the analysis performed, it is possible to predict additional raw material sources of mangiferin and other groups of xanthones using the molecular data exemplified by the Obscura section.Conclusion. Based on the data obtained, it can be concluded that the morphological classification of the genus Hedysarum L. can be confirmed within the Obscura section.

Resumen
Introduction. The species of the genus Hedysarum L. of the Fabaceae family are of significant interest in connection with the accumulation of a group of biologically active substances with antibacterial and antiviral activity against DNA-containing viruses.Aim. The purpose of the work is to develop a method for the quantitative determination of mangiferin in the aboveground part of species of the genus Hedysarum L., Hedysarum caucasicum M.Bieb., Hedysarum grandiflorum Pall., Hedysarum daghestanicum Rupr. ex. Boiss. collected in the North Caucasus by zonal capillary electrophoresis.Materials and methods. The objects of the study were species of the genus Hedysarum L., namely Hedysarum caucasicum M.Bieb., Hedysarum grandiflorum Pall., Hedysarum daghestanicum Rupr. ex. Boiss. collected in the North Caucasus. Registration of electronic spectra was carried out on capillary electrophoresis "KAPEL'®-105m" (OJSC "Lumex-marketing", Russia) with quartz capillary Leff./Ltol. = 50/60 cm, ID = 75 μm. As a standard sample, mangiferin (substance-powder, mangiferin content ≥98 %, Sigma-Aldrich, Lot SLBP4044V) was used.Results and discussion. As a result of comprehensive pharmacognostic studies of species of the kopecki genus growing in the North Caucasus under natural conditions, as well as under the conditions of introduction on the territory of the Botanical Garden of the Pyatigorsk Medical and Pharmaceutical Institute and the Mountain Botanical Garden of the Dagestan Federal Research Center of the Russian Academy of Sciences, we developed a method for the isolation and quantitative determination of mangiferin by capillary electrophoresis.Conclusion. Studies show that the use of the zonal capillary electrophoresis method in the analysis of xanthones, including the determination of the quantitative content of mangiferin, is promising. The largest content of mangiferin (0.25 %) is distinguished by Hedysarum caucasicum M.Bieb., which confirms the assumption based on molecular genetic studies, since it is this species that belongs to the Obscura section, as well as the alpine penny used to produce mangiferin. Therefore, it is possible to provide this technique for analysis of mangiferin xanthone glycoside along with spectrophotometry and high performance liquid chromatography.

Resumen
Preparing of the antiviral and antibacterial medicinal plants is a promising task of native pharmacy. In this regard, it is interesting to study species of the genus penny, namely Hedysarum caucasicum M.Bieb., Hedysarum grandiflorum Pall., Hedysarum daghestanicum Rupr. ex. Boiss., the regions of distribution, chemical composition and known pharmacological properties will allow to justify directions of their rational use, as well as creation of new phytopreparations of antiviral action on the basis of medicinal raw materials. During the complex pharmacognostic studies of three species of Hedysarum L. we have developed the method for isolation and quantitative determination of the sum of xanthones in terms of mangiferin by UV spectrophotometry. The technique takes into account the basic physical and chemical properties of xanthones, is characterized by reproducibility, high accuracy, simplicity of implementation, allows to carry out both screening evaluation of various raw objects containing mangiferin derivatives, as well as standardization of the prepared medicinal plant raw material of the penny. The developed methods are tested on the aerian organs of Hedysarum L. species, collected and dried taking into account the rules and requirements of drug raw material procurement. As a result, Hedysarum caucasicum M.Bieb herb (0.624%) was found to be the highest quantitative amount of xanthone sum in terms of mangiferin. The obtained results show the prospect of further research of the aerian part of the Hedysarum caucasicum M.Bieb. as an additional source of mangiferin. The method of quantitative determination of xanthone sum in the list for mangiferin in the above-ground part of Hedysarum caucasicum M.Bieb; Based on the obtained data, it has been found that the proposed technique is highly sensitive, reproducible and usable.

Resumen
A new species, Hedysarum dazkiriense, in the genus Hedysarum (Fabaceae) was described and illustrated here and is only known from Dazkırı district in Afyonkarahisar Province in Türkiye. The species belongs to sect. Multicaulia and it is closely related to H. syriacum, but it is distinguished from it by having 5–8 pairs and smaller leaflets (3–7 × 1–2 mm, not 4–6 pairs and 15–22 × 5–12 mm); calyx 2–3 mm long (not 8–9 mm), standard 14–16 mm long (not 18–22 (–24) mm). Also, it is similar to H. pestalozzae, but distinctly different from it by having smaller leaflets (3–7 × 1–2 mm, not 5–14 × 2.5–4 mm), smaller calyx (2–3 mm long not 4–6 mm), lomentum sparsely hirsute and without setae (not densely tomentose, with or without setae). Taxonomic descriptions, images, the identification key, phenology, palinology and the IUCN threat category of the new species were presented. In addition, the geographical distribution of H. dazkiriense, H. syriacum and H. pestalozzae were mapped.

Resumen
Hedysarum (Hedysarum spp.) roots are a primary food of grizzly bears (Ursus arctos) in the Front Ranges of the Canadian Rocky Mountains. I studied the effects of recent forest fire on yellow hedysarum (H. sulphurescens) habitat by comparing root density, mass, fibre content, ease of digging, and use by grizzly bears in and adjacent to two prescribed burns that were conducted in Banff National Park, Alberta, in 1986 (Cascade Valley) and 1990 (Panther Valley). Digging was 12-14% easier in burned than in forested habitat. In the Cascade burn, yellow hedysarum roots were significantly more abundant and heavier than in the adjacent forest. This burn was intensively dug by grizzly bears between 1995 and 1997, but no diggings were found in the adjacent forest. In the Panther burn, no significant differences in root quality or mass were found. Bears dug few roots in the burn and did not dig in the adjacent forest. Their use of these two burns demonstrates prescribed fire's potential to create important yellow hedysarum digging habitat for grizzly bears in Banff National Park.

Resumen
During field surveys in Damghan (Semnan Province, N Iran) I collected Hedysarum damghanicum Rechinger (1979: 237) of section Crinifera Boissier (1872: 512). In order to confirm the identity of the specimens, I examined the protologue and realized that the name Hedysarum damghanicum was not validly published, because, contrary to Art. 40.2 of ICN (Turland et al. 2018), two gatherings were designated as types: Rechinger 55373 (as “fl. Typus”) and Rechinger 56498 (as “fruct. Typus”). Therefore, the name Hedysarum damghanicum is validated here by choosing one gathering as the type.

Resumen
In this paper, the shrub windbreak and sand-fixing sand barrier of Bairin Youqi in Chifeng in the east of Horqin Sandy Land is the research object, three different types of plant barriers including hedysarum laeve grid sand barrier, Salix gordejevii and hedysarum laeve grid sand barrier and caragana and hedysarum laeve patch sand barrier are respectively selected, and the shifting sandy land is selected as a contrast at the same time to study its influence on the soil moisture of sandy land in the method of field locating observation method from early May to late September of 2005. Except for the contrasted sandy land, the monthly average soil moisture in each layer of plant sand barrier presents a fluctuation trend. The monthly change trend of soil moisture in the 10~20cm soil layer of hedysarum laeve grid sand barrier is the same as that of caragana and hedysarum laeve patch sand barrier. The soil moisture in 20~40cm soil layer of the three plant barriers in every month shows a big change, with the fluctuation range larger than the contrasted sandy land. The 20~60 cm soil layer is the area where the roots of sand barrier plant are centralized, therefore, the soil moisture in the root intensive area is reduced. The monthly change trend of soil moisture in 60~80cm soil layer of hedysarum laeve grid sand barrier, caragana and hedysarum laeve patch sand barrier is the same as that of the contrasted sandy land. The monthly change trend of soil moisture in the 80~100 soil layers is basically same. The minimum value of monthly average soil moisture of all kinds of plant sand barriers appears when the contrasted sandy land is 1.40%, and the maximum value appears when caragana and hedysarum laeve patch sand barrier is 4.79%, 3.4 times higher than the contrasted sandy land. The annual dynamic condition of soil moisture can be divided into: consumption period from April to June, supply period from July to August, stable period in September, which shows that the plant sand barrier is favorable for increasing the soil moisture.

Resumen
The main active component of species of the genus Hedysarum are xanthones, the main of them is C-glycoside-mangiferin, which was found in the aerial part of 17 species of Hedysarum. Mangiferin is contained in plants of the genus Hedysarum can serve as a chemotaxonomic marker of this section, it has antiviral activity against DNA-containing viruses: Herpes simplex virus, Varicella zoster, Cytomegalovirus, also has immunostimulatory properties (stimulates cellular and humoral immunity). We have prepared the phytochemical investigations of xanthones. The quantitative maintenance of the sum of xanthones in terms of a specific indicator of a mangiferin is established. The technology of a liquid extract by means of 80% of ethanol is developed, technological parameters of raw materials have been determined: content of extractive substances in raw materials (26.59%); finished product removal factor (2.48); feed absorption coefficient (3.00); Internal juice formation rate (3.37); coefficient of volume increase at dissolution of extractive substances (2,013); bulk density (0.21); dry feed filling ratio (3.7); Swollen feed filling ratio (1.3); Displacement factor (1.7). Extract of Hedysarum caucasicum is obtained with ratio of phases 1:2 in a battery of 6 diffusers. It is established that extract of Hedysarum caucasicum shows the antimicrobial activity concerning Shigella sonnei, Bacillus subtilis and B. anthracoides.

Resumen
L'autotétraploi͏̈die induite expérimentalement a été utilisée dans ce travail pour étudier les répercussions du doublement chromosomique sur le développement, les potentialités reproductives et les aptitudes à l'hybridation de quelques populations de cinq espèces du genre Hedysarum. Les informations fournies par des analyses multivariées convergent toutes vers une séparation nette de populations et des espèces aux deux niveaux de ploi͏̈die 2x et 4x. Il en ressort que la réponse au doublement chromosomique est plus nette pour les caractères liés au gigantisme et à la reproduction que pour les caractères d'architecture ou de la croissance. La multiplication numérique des chromosomes s'accompagne d'irrégularites mei͏̈otiques, de modifications profondes de l'architecture des grains de pollen et une baisse des potentialités reproductives. L'analyse de divers résultats obtenus a permis de mieux comprendre l'incidence de l'autotétraploi͏̈disation et d'émettre des hypothèses relatives aux critères de regroupements et de divergences au sein du genre Hedysarum.

Resumen
Les fortes teneurs en éléments traces métalliques (ETMs) présents dans les déblais miniers entraînent généralement une forte réduction de la diversité végétale et microbienne. Selon les caractéristiques physico-chimiques des sols, la nature des métaux, leur concentration et leur spéciation, seules certaines espèces végétales et microbiennes ont développé des mécanismes particuliers et se sont adaptées à la présence d'ETMs. C'est le cas d'Anthyllis vulneraria et d'Hedysarum coronarium, deux Fabacées qui sont présentes sur d'anciennes mines de Zn/ Pb respectivement au sud de la France et au nord de la Tunisie. L'étude de l'absorption du Zn chez quatre sous-espèces d'A. vulneraria a montré que seule la sous-espèce carpatica présente sur l'ancienne mine Zn/Pb des Avinières, peut croître en présence de teneurs élevées en Zn et accumule des quantités élevées de ce métal sans montrer de symptômes de toxicité. Les données obtenues ont révélé qu'A. vulneraria sous espèce carpatica est une plante hypertolérante et accumulatrice de Zn. L'inoculation d'A. vulneraria avec ses bactéries symbiotiques fixatrices d'azote, Mesorhizobium metallidurans STM2683 (souche métallicole) et Mesorhizobium sp. STM2682 (souche non métallicole), a induit une diminution très significative de la teneur en Zn dans la plante. Par contre, seule la souche métallicole a montré un effet protecteur vis-à-vis des sous espèces sensibles d'A. vulneraria lorsque celles-ci sont exposées à une concentration modérée en Zn. La diversité phylogénétique et phénotypique des bactéries symbiotiques fixatrices d'azote associées à H. coronarium isolées du substrat de l'ancienne mine de Zn/Pb de Fej El Hdoum et du sol d'une parcelle agricole à El Krib a mis en évidence (i) l'appartenance de tous les isolats étudiés au genre Rhizobium, (ii) l'existence de différents niveaux de tolérance au Cd et l'absence de tolérance au Zn pour les isolats issus du substrat de Fej El Hdoum (iii) le lien étroit entre la présence de la plante hôte, H. coronarium et de sa bactérie symbiotique fixatrice d'azote sur un site donné. Ainsi, compte tenu des contraintes imposées par la présence des ETMs, l'utilisation de Fabacées en première séquence de végétation pour favoriser l'entrée d'azote et faciliter l'installation d'une couverture végétale stable et pérenne à même de phytostabliser les déblais miniers, rend indispensable la sélection des associations les mieux adaptées aux conditions environnementales locales
High contents of trace metals present in waste rock mining causes a significant reduction in plant and microbial diversity. According to soil physico-chemical characteristics, metal nature, concentration and speciation, only some plant and strain species have developed specific mechanisms to cope with trace metal toxicity. This is the case of Anthyllis vulneraria and Hedysarum coronarium, two Fabaceae that are present on Zn / Pb ancient mines respectively in southern France and northern Tunisia. The Zn absorption study in four subspecies of A. vulneraria showed that only the carpatica subspecies, present on the Zn / Pb ancient mine of Les Avinières, can grow with high Zn concentrations and accumulate high levels of this metal without showing toxicity symptoms. Thus, A. vulneraria subsp. carpatica should be considered as a Zn-hypertolerant and accumulator plant. Inoculation of A. vulneraria with a nitrogen-fixing symbiotic bacterium, Mesorhizobium metallidurans STM2683 (metallicolous strain) or Mesorhizobium sp. STM2682 (non- metallicolous strain), induced a significant decrease of Zn content in the plant. However, only the metallicolous strain showed a protective effect for sensitive A. vulneraria subspecies when symbiotic plants were exposed to a moderate Zn concentration. Phenotypic and phylogenetic diversity of nitrogen-fixing symbiotic bacteria associated with H. coronarium isolated from the Zn / Pb ancient mine of Fej El Hdoum and an agricultural parcel of El Krib highlighted (i) that all studied isolates belong to the genus of Rhizobium, (ii) the existence of different Cd tolerance levels and the absence of Zn tolerance for isolates from the Fej El Hdoum substrate (iii) the close link between the presence of the host plant, H. coronarium and their symbiotic nitrogen-fixing bacteria on a given site. Thus, given the constraints imposed by heavy metals, the use of Fabaceae in a first sequence of vegetation to promote nitrogen entrance and facilitate the installation of a sustainable plant cover able to phytostabilise waste rock mining, necessitates the selection of the best adapted associations to local environmental conditions

Le complexe h. Spinosissimum comprend les deux sous-especes h. Spinosissimum ssp capitatum et ssp euspinosissimum. Elles sont morphologiquement voisines et poussent spontanement dans l'ensemble du bassin mediterraneen. Les diverses prospections et les differentes analyses realisees montrent d'une part que ces sous-especes se repartissent dans des regions bien distinctes avec la possibilite de se retrouver en melange dans les zones limitrophes situees le long de la barriere geographique qui separe leurs aires de distribution naturelles et que d'autre part elles different fondamentalement par leur mode de reproduction: la ssp h. Capitatum est preferentiellement allogame et la ssp h. Euspinosissimum est a autogamie predominante. Dans le present travail, nous avons compare la variation genetique des populations naturelles en nous basant sur deux approches: une approche biometrique, pour etudier la variabilite morphologique des caracteres quantitatifs et une biochimique, pour analyser le polymorphisme de 11 systemes enzymatiques et etudier le rflp des adn cytoplasmiques. Sur la base de ces donnees, les relations phylogenetiques entre les deux sous-especes ont ete elucidees. L'analyse globale de la diversite genetique etudiee par les differentes approches a permis de mettre en evidence une structure genetique differente d'une sous-espece a l'autre: 1) une variabilite genetique des populations appreciable aux niveaux morphologique et enzymatique; 2) des differences significatives entre populations plus importantes chez h. Euspinosissimum que chez h.

Resumen
L'etude de l'action de l'antimoine sur la vegetation d'une zone miniere (djebel hamimat, algerie) a mis en evidence une selection severe sur les divers groupements vegetaux et des comportements differents des especes vegetales en presence du toxique: toxicophobes, indifferentes ou toxicophytes. Le dosage de l'antimoine dans les feuilles de quelques plantes fait apparaitre, en comparaison avec les teneurs en antimoine des sols, differents modes de tolerance vis-a-vis du metal: exclusion, accumulation ou meme concentration. Les teneurs en antimoine determinees pour certaines especes vegetales sont exceptionnellement elevees par rapport aux teneurs normales. Des tests experimentaux in vitro, sur milieu gelose, realises avec un premier lot de germinations issues des semences de deux populations d'une espece indifferente et accumulatrice, hedysarum pallidum desf. , montrent que la population se developpant sur des deblais de mine est plus adaptee a la presence d'antimoine dans le milieu que la population provenant d'un sol normal. La presence d'antimoine dans le milieu semble etre a l'origine de l'apparition de neoformations sur les cotyledons de plusieurs germinations. Des analyses enzymatiques realisees sur un second lot de germinations provenant des memes populations mettent en evidence une importante variation electrophoretique et des differences entre les deux populations, dans la distribution et les frequences de certaines bandes isoenzymatiques. Les resultats des tests experimentaux et des analyses enzymatiques laissent supposer une evolution de races tolerantes ou ecotypes parmi les populations d'hedysarum pallidum desf.

L'analyse de caracteres morphologiques a revele une forte variabilite phenotypique liee, au moins en partie, a leur origine geographique et dans le maintien de laquelle le regime de reproduction allogame de l'espece joue un role determinant. Les plantes, produites a partir de cals de cotyledons, folioles et hypocotyl cultives in vitro, derivent soit de bourgeons neoformes, soit d'embryons somatiques. Elles sont en majorite diploides et presentent une faible variabilite morphologique. Toutefois, leur aptitude a la reproduction sexuee et leur vigeur sont plus faibles que celles des plantes dont elles sont issues. Cette baisse de performance se retrouve chez leur descendance issue de graines

Resumen
Germination strategies and early seedling development of selected Medicago and Hedysarum species were evaluated to identify plants with high potential for range rehabilitation in central Tunisia. Temperature (5°C to 25°C) and water stress (0 MPa to -0.8 MPa) affected the germination percentage of all Medicago and Hedysarum species. Water stress had a greater effect on percent germination than did temperature, however, the nature of the effect of water potential depended on temperature. Australian medics were more depressed by temperature extremes and low water potential than were Tunisian accessions. Optimum germination of Medicago polvmorpha var. Circle Valley and Medicago trucatula var. Jemalong was at 15 °C and 0 MPa. Germination was highly reduced at higher temperatures and water stress. Tunisian Medicago truncatula germinated better at lower temperatures (5 °C to 15 °C). Hedysarum carnosum germinated more completely at high temperatures. (15°C to 20°C). Medicago laciniata germinated well across a wide range of temperature but germination decreased as water stress increased. Rapid rates of root elongation are beneficial to plants in semiarid environments. High temperature accelerated rates of root elongation and low temperature retarded the rates. The degree of retardation varied with the species and the temperature range. Maximum root elongation occurred at 15°C and minimum root elongation occurred at 5°C. Medicago laciniata had the fastest root elongation rate at 5°C and 15°C . Medicago truncatula was equal to Medicago laciniata at 5°C. Hedysarum carnosum had rapid root elongation at 10°C and 15°C compared to 5°C. A Tunisian accession Medicago polymorpha had the slowest root elongation at all temperatures. A quantitative growth analysis was used to assess the effect of environmental conditions on the species performance over a period of 49 days. Mean relative growth rate (mRGR) varied among species. This variation suggested size hierarchies in relative performance among species. The largest plant, Tunisian Medicago truncatula had the largest mRGR and the smallest plant, The Tunisian Medicago polvmorpha had the lowest mRGR. The derived parameters, leaf area ratio (LAR) and unit leaf ratio (ULR), were not consistent with the size hierarchies obtained by mRGR. The Root to shoot ratio (R/S) varied among the species. The Tunisan Medicago truncatula had high root to shoot ratios at low temperature and its R/S ratio decreased at higher temperature. Slow growing species had high R/S ratio. Medicago laciniata was an exception, it produced low R/S ratio because of its long, and thin root system.

Resumen
The results of the study of rare communities in the middle reaches of the Lena river valley, one of the most floristically rich regions of Yakutia, are presented. There are grow populations of 81 species of vascular plants listed in the regional Red Book. Populations of 35 species are covered by various types of protection. Five populations of endemic plants of the North-East of Russia, 13 species living on the northern limit of their ranges, and 3 endemic plants of the Central Yakutia were not included in protected areas (PAs). The relict steppe communities with Artemisia martjanovii Krasch. ex Poljak., Krascheninnikovia ceratoides (L.) Gueldenst., Hedysarum gmelinii Ledeb., Astragalus lenensis Shemetova, Schaulo et Lomon. are under threat of complete extinction.
