The objectives of the present study were to determine salt tolerance levels of 12 different common vetch (Vicia sativa L.) cultivars at germination stage in the presence of 250 mM NaCl and to reveal genetic relationships based on gene targeted functional markers (GTFMs) associated with salt tolerance. The results revealed the presence of a significant genetic variation among the cultivars although s alt stress significantly reduced all germination parameters tested. The cultivar Ozveren was the most salt tolerant with 20.1% reduction in final germination percentage compared to control seeds while cultivars Alınoglu, Ayaz and Bakir did not germinate. The maximum delays in germination rate (G50 = 3.78 days) and synchrony (G10-90 = 3.45 days) were obtained from the cultivars Urkmez and Ozveren, respectively. The GTFMs provided a total of 53.1% polymorphism. The primers of MtSOS2 gene gave the highest numbers of alleles per primer pair while the highest polymorphism rate (77.8%) was obtained from the MtP5CS gene. The first three components of principal component analysis explained 57.63% of total variation. This study concluded that the cultivars determined to be salt tolerant and sensitive at germination stage distributed into three main clades determined by UPGMA analysis while the GTFMs associated with salt tolerance successfully determined the genetic relationships of common vetch cultivars.
本研究的目的是测定12个不同品种紫薇(Vicia sativa L.)在250 mM NaCl存在下萌发期的耐盐水平，并基于基因靶向功能标记(GTFMs)揭示与耐盐相关的遗传关系。结果表明，尽管胁迫显著降低了所有的发芽参数，但品种间存在显著的遗传变异。品种Ozveren耐盐性最强，最终发芽率比对照降低20.1%，而品种Alınoglu、Ayaz和Bakir均未发芽。乌尔克梅兹和欧兹芬的萌发延迟时间最长，分别为G50 =3.78 d和G10-90 =3.45 d。gtfms的多态性为53.1%。mtsos2基因引物的等位基因数量最多，而MtP5CS基因的多态性率最高，为77.8%。主成分分析的前三个分量解释了57.63%的总变异。本研究认为，通过UPGMA分析确定的萌发期耐盐敏感品种分布在3个主要分支，而与耐盐相关的GTFMs则成功地确定了普通豌豆品种的亲缘关系。

Our phytosociological study in Montenegro (Ćemovsko polje) deals with the syntaxonomy of arid grasslands in the Adriatic region and, in particular, different interpretations of plant communities dominated by Asphodelus ramosus. The main aims of this study were to contribute to knowledge of the composition of dry grasslands dominated by Asphodelus ramosus in Montenegro and to compare instances of Asphodelus ramosus dominated vegetation along the Adriatic. Our vegetation dataset included 82 phytosociological relevés: 17 from our recent field work and 72 relevés of South European Asphodelus ramosus communities. Ordination analysis (NMDS) was used for comparison of Asphodelus ramosus dominated communities in the Adriatic region. The Asphodelus ramosus community from Montenegro was classified into Bromo erecti-Chrysopogonetum grylli. The analysis revealed two distinct vegetation groups: grassland communities of the vegetation class Festuco-Brometea from Montenegro, Croatia and Albania, and edge vegetation of the new class Charybdido pancratii-Asphodeletea ramosi from Italy. Comparison with similar vegetation types shows high similarity with associations on the eastern Adriatic coast, where they are treated as grassland communities belonging to the alliance Chrysopogono grylli-Koelerion splendentis, order Scorzoneretalia villosae, class Festuco-Brometea.

A new species of Festuca from the Western Taurus Mountains (Antalya, Turkey) is described here and named F. albomontana. The new species can clearly be distinguished from the other species included in the F. alpina group by its leaf anatomical features. It has a geographically isolated position in the Western Tauruses whereas a closely related species, F. sommieri, is very local in the Black Sea Region of Turkey. It is suggested that it should be in the “critically endangered” threat category according to the International Union for Conservation of Nature (IUCN) criteria. Observations on the ecology of the population are noted.

Lepidium oblongum, of American origin is a new member of the European adventive flora, only detected in Romania so far. The first Hungarian stand was discovered in 2018, and others in 2020. Based on our studies, we detail its morphological characteristics in comparison with other Lepidium species. We present a new drawing and a table to help identify the species. Lepidium oblongum is easily identifiable by its divided (lobed or lobed-dentated) upper stem leaves. By analyzing selected climatic parameters we show that the new European habitats are found in the drier and cooler summer subtype of the humid continental climate belt. In Hungary, it spreads directly along the railways. The establishment of individual populations can be influenced by the location of cargo unloading and the movement of railway workers. Lepidium oblongum occupies gravelly, sun-exposed habitats along Hungarian railway tracks such as loading platforms, guardhouses and goods stations. Based on its high stress and climatic tolerance and initial spread-rate, it is consider to be a naturalized member of the European adventive flora, that could be potentially invasive along the European railways

Aethionema lepidioides Hub.-Mor. is an endangered endemic species in Turkey with a very narrow natural distribution area. The present study aims to reveal the structural features of this species. For this purpose, its unknown morphological features – such as leaf, petal, sepal dimensions and shapes, filament and anther lengths, as well as seed dimensions, shape, colour and micromorphology – have been studied for the first time. To reveal the pollen characteristics of Ae. lepidioides, light microscope and SEM studies were conducted. Additionally, in the present study the anatomical features of Ae. lepidioides were also studied for the first time. The Ae. lepidioides leaves were found to be linear-oblanceolate, with an entire margin and a subacute to obtuse apex. The seeds were found to be dark brown and oval-shaped, with reticulated surface ornamentation. Anatomical studies found roots in the secondary growth stage, with xylem-filled pith. The stem was in the primary growth stage, featuring a multi-layer cortex under its outermost single-layered epidermis, a pronounced endodermis and a central cylinder beneath. The leaves were thick, amphistomatic and covered with a prominent wax layer. Their mesophyll was equifacial, and their stoma type was anisocytic. A stomatal index of 26 was found for the upper epidermis, while a corresponding index of 28.4 was found for the lower epidermis. The pollens were monad, radially symmetrical and isopolar. The pollen type was colpate, and the pollen shape was found to be prolate-spheroidal with a P/E ratio of 1.08.

Class Polygono-Poetea annuae Rivas-Mart. 1975 includes therophyte-rich vegetation on trampled habitats. The study presents the first analysis of the syntaxonomy of this class and its ecology in Bulgaria. One hundred seventy-five relevés from this class were collected and stored in the Balkan Vegetation Database during 2017–2020. Numerical classification (hierarchical divisive) and ordination were performed by JUICE and CANOCO software packages. Diagnostic species were determined by calculating the Phi-coefficient. Four associations, Sclerochloo durae-Polygonetum arenastri, Polygonetum arenastri, Lolio-Polygonetum arenastri and Poëtum annuae, were recognized. Their floristic composition has been shaped mainly by climatic and soil conditions. Sclerochloo durae-Polygonetum arenastri association has been found at lower altitudes, occurring in fully lighted habitats with high radiation, whereas Poëtum annuae has been found at higher altitudes in wetter and cooler areas. On the other hand, stands of Polygonetum arenastri have been found on nutrient-rich soils, whereas communities of Lolio-Polygonetum arenastri were distributed in warmer and nutrient-poor areas. The Polygono-Poetea annuae class is still poorly studied in Bulgaria and much more information from all regions of the country needs to be collected and analyzed.

Floristic investigations on the eastern part of Adriatic coast in Montenegro and Bosnia and Herzegovina led to the discovery of three glasswort taxa new for the area: Arthrocaulon macrostachyum (Moric.) Piirainen et G. Kadereit and Salicornia procumbens Sm. subsp. procumbens and S. perennis Mill. All three taxa were recorded in the abandoned basins of Tivat Saline in Montenegro, while S. perennis was also found in the Klek Peninsula in Bosnia and Hercegovina. According to the IUCN criteria, the status of the newly reported taxa was classified as “critically endangered” (CR) in both countries.

In this study, the micromorphology of the vegetative and reproductive structures of the endemic Centaurea glaberrima Tausch subsp. divergens (Vis.) Hayek (Asteraceae), using scanning electron microscope (SEM), is presented for the first time. Uniseriate whip-like non-glandular and biseriate glandular trichomes are found on the surface of all aboveground parts (stem, leaves, peduncles, involucral bract). On the adaxial leaf epidermis ribbed thickenings (striation pattern) of outer periclinal cell walls, slightly curved anticlinal cell walls and anomocytic stomata are noticed. Rugose abaxial surface with thorny protuberances of the involucral bract is documented. Corolla is glabrous with longitudinally parallel epidermal cells with distinct straight outline. Isopolar, radially symmetric and tricolporate microechinate pollen grains are seen. Short stylar hairs, without cuticular striations, are present along the outer sides of the style, while the inner sides (abaxial surface) constitute the papillate stigmatic surface. Microcharacters found in cypsela are as follows: slightly ribbed body; rotund base; lateral and concave insertion; short, unicellular curly acute trichomes; smooth epidermis; fine-sulcate ornamentation; rod shaped epidermal cells with short, obtuse end walls and straight anticlinal walls; poorly developed minutely dentate pericarp rim; and dimorphic pappus with bristles of different length and morphology, with pinnules restricted to the margins of the bristles. The results obtained contribute to knowledge about the micromorphology of the studied endemic species and provide features for its better identification. The taxonomic significance of the analyzed characters is discussed. Some well defined microcharacters of the studied species might have taxonomic value

The salinity of the soil and irrigation water is one of the great challenges of agriculture. Salinity can have harmful effects on physiological processes and plant growth, including Tropaeolum majus L. (Tropaeolaceae). The application of phytohormones can be a strategy to mitigate these effects. The aim of this study was to evaluate the application of jasmonic acid, salicylic acid, cytokinin and polyamine as attenuators of salt stress in T. majus. Three levels of salt stress were used: 0 mM NaCl (no stress), 50 mM NaCl (moderate stress) and 100 mM NaCl (severe stress). Four phytohormones and a control treatment were used: control (deionized water), jasmonic acid (200 µM), salicylic acid (2 mM), cytokinin (6-benzylaminopurine – 10 µM) and polyamine (spermine – 1 mM). Growth and gas exchange parameters were evaluated. Applied in conditions of moderate salt stress, all the phytohormones were efficient in improving plant height and leaf area (except salicylic acid); cytokinin and polyamine improved the number of flowers as well as gs, A and iCE; jasmonic acid improved the stem dry mass and total dry mass. In relation to severe salt stress, applications of jasmonic acid and polyamine were efficient in improving plant height; cytokinin improved leaf dry mass as well as gs, A, E, WUE, iWUE and iCE. The application of cytokinin, polyamine and jasmonic acid can be used to mitigate moderate salt stress in T. majus.
土壤和灌溉用水的盐度是农业面临的巨大挑战之一。盐度会对植物的生理过程和生长产生有害的影响，其中包括Tropaeolum majus L. (Tropaeolaceae)。植物激素的应用可能是减轻这些影响的一种策略。本研究旨在探讨茉莉酸、水杨酸、细胞分裂素和多胺作为盐胁迫衰减剂的应用价值。采用0 mM NaCl(无胁迫)、50 mM NaCl(中度胁迫)和100 mM NaCl(重度胁迫)三个盐胁迫水平。采用四种植物激素和对照处理:对照(去离子水)、茉莉酸(200µM)、水杨酸(2 mM)、细胞分裂素(6-苄基氨基嘌呤- 10µM)和多胺(精胺- 1 mM)。对生长和气体交换参数进行了评价。在中等盐胁迫条件下，除水杨酸外，其余激素均能有效提高植株高度和叶面积;细胞分裂素和多胺提高了花数，提高了gs、A和iCE;茉莉酸提高了茎干质量和总干质量。在重度盐胁迫下，施用茉莉酸和多胺能有效提高株高;细胞分裂素提高了叶片干质量、gs、A、E、WUE、iWUE和iCE。细胞分裂素、多胺和茉莉酸的应用可以缓解大叶参的中度盐胁迫。
