Salt habitats are extreme and unique environments found from Austria through Hungary to the Vojvodina Province in Serbia. In our study, we investigated eight saline habitats (channeled salt marshes, moist salt meadows and saline ponds), from which we collected plankton, epipelic and epiphytic diatoms. Seventeen diatom taxa new for the Serbian diatom flora were recorded. In addition, the genus Haslea, with one species (H. spicula), was recorded for the first time in Serbia. The identified taxa were sporadic or rare in the samples.
从奥地利到匈牙利,再到塞尔维亚的伏伊伏丁那省,盐的栖息地是极端而独特的环境。在本研究中,我们调查了8个盐沼生境(通道盐沼、湿盐草甸和盐沼),收集了浮游生物、浮游硅藻和附生硅藻。记录了塞尔维亚硅藻区系新发现的17个硅藻类群。此外,在塞尔维亚首次记录到Haslea属,其中有1种(H. spicula)。所鉴定的分类群在样品中是零星的或罕见的。

In this study, we report genome size (C-values) estimated using flow cytometry for 18 taxa of Asteraceae from Turkey, 17 of which are here assessed for the first time. The studied taxa belong to the genera Achillea (one species), Anthemis (one subspecies), Tanacetum (four taxa) and Crepis (12 taxa). Additionally, chromosome numbers of nine taxa of Crepis are provided, four counts being new reports and the remainder confirming previous data. The 2C-values of the studied taxa range from 2.08 to 11.06 pg, which represent more than fivefold variation. The systematic and evolutionary significance of genome size is discussed within the framework of the results obtained in this study.

Melampsora epitea, known to cause rust on the complex of Salix retusa prostrate willows distributed in the subalpine and alpine belt of the mountains of Central Europe, is here documented for the first time in Montenegro and North Macedonia growing at six localities. It is not new for Serbia, but the records come from a newly reported host, namely Salix serpyllifolia. The pathogen?s distribution presumably is wider than initially believed, and further surveys need to be conducted.
Melampsora epitea,已知会导致分布在中欧山脉亚高山和高山带的柳柳(Salix retusa)匍匐柳树上的锈病,在黑山和北马其顿的六个地方首次被记录下来。这对塞尔维亚来说并不新鲜,但这些记录来自一种新报道的宿主,即Salix serpyllifolia。病原体?S的分布可能比最初认为的要宽,需要进行进一步的调查。

Arbutus unedo is a species mainly used for landscaping purposes and lately for honey production. Its antioxidant characteristics have also been a subject of of research interest. The germination of pollen grains freshly collected from flowers was tested in vitro, and 30% sucrose gave the highest pollen germination. Subsequently, three growth regulators belonging to the categories of gibberellins and brassinosteroids [24-epibrassinolide (Ebl) and 22S,23S-homobrassinolide (Hbl)] were added to the growth medium singly or in double combinations (gibberellin + brassinosteroid), and the petri dishes were kept for 24 hours at 26?1?C. The results showed that the highest germination rates were obtained from treatments with 0.01 ppm Hbl (45.47%) and 0.001 ppm Hbl (26.74%). They were followed by treatments with 0.001 ppm Ebl, 25 ppm GA3 and 0.1 ppm Ebl. As the concentration of GA3 increased, the germination rate declined considerably. Statistical analysis of the combined treatments showed that combinations of growth regulators lowered the germination rates compared to their individual application. Moreover, action of the lowest GA3 concentration (25 ppm) best matched the effects of brassinosteroids, and increasing the GA3 concentration in combined treatments did not improve germination. The highest germination was obtained with 0.1 ppm Hbl, followed by all Ebl treatments. Brassinosteroids might be an inducer of pollen germination in plants depending on their type and concentrations. When individually included in the growth medium, the extent of this induction was greater with the homobrassinolide than with the epibrassinolide. Their interactions with gibberellins are shown to be mostly dependent on the concentration of gibberellic acid used. The tested epibrassinolide was more consistent than the homobrassinolide in maintaining higher germination levels. The findings of this study indicate that gathering more information from studies involving other plant species is needed to clarify the role of brassinosteroids in in vitro and in vivo germination.
杨梅是一种主要用于园林绿化的树种,最近用于蜂蜜生产。其抗氧化特性也一直是研究的热点。在离体条件下,对鲜花新鲜采集的花粉粒进行了萌发试验,30%蔗糖的花粉萌发率最高。随后,在生长培养基中分别加入3种生长调节剂[24-表油菜素内酯(Ebl)和22S、23s -同油菜素内酯(Hbl)]或双组合(赤霉素+油菜素内酯),在26℃下培养24小时。结果表明,0.01 ppm Hbl和0.001 ppm Hbl处理的发芽率最高,分别为45.47%和26.74%。随后分别用0.001 ppm Ebl、25 ppm GA3和0.1 ppm Ebl处理。随着GA3浓度的增加,发芽率明显下降。组合处理的统计分析表明,与单独施用相比,组合施用生长调节剂降低了发芽率。此外,最低GA3浓度(25 ppm)的效果与油菜素内酯的效果最匹配,而增加GA3浓度的联合处理并没有提高发芽率。以0.1 ppm Hbl处理的发芽率最高,所有Ebl处理次之。油菜素内酯可能是植物花粉萌发的诱导剂,这取决于它们的类型和浓度。当单独加入生长培养基时,高油菜素内酯的诱导程度大于表油菜素内酯。它们与赤霉素的相互作用主要取决于所用赤霉素酸的浓度。表油菜素内酯比高油菜素内酯在保持较高的萌发水平方面更一致。本研究结果表明,需要从其他植物物种的研究中收集更多的信息来阐明油菜素内酯在体外和体内萌发中的作用。

The composition of charophyte taxa and their habitat preferences in water bodies of the Artabel Lakes Nature Park were investigated on 15 August 2013 and 13 August 2016. A total of 73 taxa belonging to Conjugatophyceae (Zygnematophyceae) and Klebsormidiophyceae were recorded. The genera Cosmarium (37), Staurastrum (10) and Closterium (7) were most abundant. The partly unexpected presence of certain desmid taxa, i.e., taxa characteristic of eutrophic water, was recorded. Filamentous charophytes were represented by three taxa. The Willis curve for the distribution of species to genera had a trend line of R2 = 0.9123. Bioindication, statistical methods and comparative floristic results show that water in all of the studied lakes was fresh, of low-conductivity, circum-neutral and with little organic pollution. Four groups of lakes were identified as a result of statistical comparison of their environmental and biological variables. Bioindication results can be used as references for future monitoring of the lakes in protection of the species found in the Artabel Lakes Nature Park and can also be included in the National Water Quality Standard System of Turkey.

Bryophytes inhabit all ecosystems on the Earth except seas. Thus, it is commonly accepted to ask are there real halophytes among bryophytes? However, some species do inhabit salty grassland or even brackish waters. Not much research has been done on the physiological reaction of moss species to salt stress. In order to study these responses, we selected three moss species, two of which are considered to be halophytes?Entosthodon hungaricus (Funariaceae), Hennediella heimii (Pottiaceae) and the non-halophytic model moss Physcomitrella patens (Funariaceae) and tested salt effects on them in controlled conditions. The idea was to show if there is tolerance to salt in the selected moss species and to document it if there is a difference in salt tolerance among them. Established in vitro moss cultures of gametophores were used to test various developmental parameters for the selected moss species. Morpho-developmental parameters (secondary protonema diameter and the index of multiplication) and biochemical parameters (pigment content and antioxidative capacity) were analysed in relation to salt concentration and time of exposure. All of the tested moss species tolerated salt stress to some extent and during some time of exposure to it. Recovery after salt stress depended both on the concentration of salt and duration of the stress. The three tested moss species did not show similar patterns of response to salt stress.
苔藓植物栖息在地球上除了海洋以外的所有生态系统中。因此,人们普遍认为苔藓植物中是否存在真正的盐生植物?然而,有些物种确实栖息在咸草地甚至微咸水域。关于苔藓类植物对盐胁迫的生理反应的研究还不多。为了研究这些反应,我们选择了三种苔藓,其中两种被认为是盐生植物。在对照条件下,研究了盐对拟生模式苔藓(拟生蕨科)、拟生蕨(拟生蕨科)和拟生模式苔藓(拟生蕨科)的盐效应。这个想法是为了证明在选定的苔藓物种中是否有耐盐性,并记录它们之间的耐盐性是否存在差异。利用已建立的苔藓配子体离体培养物,对所选苔藓物种的各种发育参数进行了测试。分析了形态发育参数(次生原丝体直径和增殖指数)和生化参数(色素含量和抗氧化能力)与盐浓度和暴露时间的关系。所有被测试的苔藓物种都在一定程度上和在一段时间内耐受盐胁迫。盐胁迫后的恢复取决于盐浓度和胁迫时间。三种苔藓对盐胁迫的反应模式不相似。

The behaviour of carbohydrate metabolism in a plant, particularly its total starch content, total soluble sugar (TSS) content and their utilisation, is of great importance in coping with abiotic stress conditions. With this in mind, we studied total starch and TSS contents, survival, growth, biomass accumulation and stomatal conductance in Rhizophora mucronata under conditions of prolonged submergence and water stress for a period of 11 months. The experiment was designed in such a way as to include three replicates per each treatment level, about 1600 young mangrove plants being subjected to study in the process. Under conditions of prolonged submergence and high levels of water stress, a small number of mangrove plants survived and they were promptly exhausted due to higher starch utilisation rates (0.75-1.05% dry mass/month). Although TSS content was increased under these intense stress conditions, it was not matched by increased seedling growth or biomass production; instead, a significant reduction in growth (i.e., ~78%) and dry matter content was observed in stressed seedlings as compared to young plants in the respective controls. It follows that the intense increase of TSS content might be due to the direct conversion of starch to soluble sugars in order to produce metabolic energy for tolerance mechanisms like osmoregulation and root anatomical adaptations under stress conditions. This indicates that more energy is allocated for plant maintenance than for growth and biomass production under stress conditions, which might be a good acclimatory strategy to rescue young mangrove plants at the early phase. However, stomatal closure under stress conditions may have caused restricted photosynthesis. Therefore, stress-induced starch degradation may upsurge, which in turn might lead in the long-run to carbon starvation, a condition lethal to mangrove seedlings.
植物的碳水化合物代谢行为,特别是其总淀粉含量、总可溶性糖(TSS)含量及其利用,在应对非生物胁迫条件下具有重要意义。为此,研究了长时间浸没和水分胁迫11个月条件下毛根霉总淀粉和TSS含量、存活、生长、生物量积累和气孔导度。实验的设计是这样的,每个处理水平包括三个重复,在这个过程中,大约1600棵年轻的红树林被研究。在长时间淹没和高度缺水的条件下,少数红树林植物存活下来,但由于较高的淀粉利用率(0.75-1.05%干质量/月),它们迅速耗尽。在这些强胁迫条件下,虽然TSS含量增加,但幼苗生长和生物量的增加并不匹配;相反,与相应对照的幼苗相比,胁迫幼苗的生长(即~78%)和干物质含量显著降低。因此,TSS含量的急剧增加可能是由于淀粉直接转化为可溶性糖,以产生代谢能量,以适应胁迫条件下的渗透调节和根系解剖适应等耐受机制。这表明在胁迫条件下,分配给植物维持的能量比分配给生长和生物量生产的能量要多,这可能是一种较好的适应策略,可以在早期挽救红树林幼树。然而,在逆境条件下,气孔关闭可能导致光合作用受限。因此,应力诱导的淀粉降解可能会增加,这反过来可能导致长期的碳饥饿,这是一种对红树林幼苗致命的条件。

A detailed examination of the phenolic profile, ascorbic acid content and antioxidant and antimicrobial capacities of extracts and jams of the fruits of two traditionally used Sorbus species, viz., S. domestica and S. intermedia, was carried out in the present study. Use of the LC-MS/MS technique revealed the presence and content of 44 phenolics, the most dominant compounds being amentoflavone in S. domestica and chlorogenic acid in S. intermedia extracts. Jam of both species showed the highest content of ?scorbic acid. In comparison with BHT (butylated hydroxytoluene) and PG (propyl gallate) antioxidant standards, both Sorbus species exhibited moderate antioxidant action. Some extracts of S. domestica and S. intermedia inhibited the growth of two clinically relevant bacterial strains. The presented results support the belief that Sorbus fruits are food with health-promoting properties.
本研究对两种传统使用的Sorbus属植物,即S. domestica和S. intermedia的果实提取物和果酱的酚类成分、抗坏血酸含量、抗氧化和抗菌能力进行了详细的研究。采用LC-MS/MS技术鉴定了44种酚类化合物的存在和含量,其中家参提取物中主要化合物为氨基黄酮,中间提取物中主要化合物为绿原酸。两种果酱中-坏血酸含量最高。与BHT(丁基羟基甲苯)和PG(没食子酸丙酯)抗氧化标准相比,这两种Sorbus都表现出中等的抗氧化作用。家蝇和中间链球菌的部分提取物抑制了两种临床相关菌株的生长。本研究结果支持sorsors果实是具有促进健康特性的食物的观点。
