Bosnia and Herzegovina has a long history of bryophyte flora research. However, it is still considered insufficiently investigated, and until recently the bryophyte investigations were completely neglected. Hence new records for the country are expected with novel exploration. Here, we report one liverwort (Porella obtusata) and four moss species (Bryum klinggraeffii, Cinclidotus danubicus, Habrodon perpusillus and Imbribryum subapiculatum) new for the country bryophyte flora. With these new records bryoflora of Bosnia and Herzegovina numbers 673 taxa (no hornworts, 134 liverworts and 539 mosses).
波斯尼亚和黑塞哥维那有着悠久的苔藓植物区系研究历史。然而,人们仍然认为对其研究不足,直到最近,苔藓植物的研究才被完全忽视。因此,随着新的探索,该国有望出现新的记录。在此,我们报道了一种苔草(Porella obtusata)和四种苔藓(Bryum klinggraeffii、Cinclidotus danubicus、Habrodon perpusilus和Imbribrium subapiculatum),它们是国家苔藓植物区系的新物种。根据这些新记录,波斯尼亚和黑塞哥维那苔藓植物区系共有673个分类群(无角类、134个苔类和539个苔藓)。

With the scarcity of good quality water, plants like tomatoes will be more susceptible to excess boron (EB) in Mediterranean regions. The effects of EB on the growth, free, semi-bound, and bound boron (B) concentrations, and macromolecules of the Solanum lycopersicum L. cultivar Castle Rock, were investigated in this study. Seedlings were exposed to four levels of EB using boric acid. The results manifested that EB inhibited tomato growth, total water content, and photosynthetic pigments. EB harmed the membrane stability, as seen by increased potassium (K) leakage, UV absorbance metabolites, and electrolyte conductivity (EC) in leaf disc solution. EB raised concentrations of free, semi-bound, and bound forms of B in seedlings. Fourier transform infrared spectroscopy (FTIR) data revealed that EB induced uneven wax deposition, altered the shape of cell walls, and lowered cellulose synthesis in seedlings. EB affected the amide I and amide II indicating damage to the protein pools. These results provide new insights into understanding the specific effects of EB on the functional groups of different macromolecules of tomato seedlings.
由于缺乏优质水,像西红柿这样的植物在地中海地区更容易受到过量硼的影响。研究了EB对番茄品种Castle Rock生长、游离硼、半结合硼和结合硼浓度以及大分子的影响。使用硼酸将幼苗暴露在四个水平的EB中。结果表明,EB对番茄生长、总含水量和光合色素均有抑制作用。EB损害了膜的稳定性,表现为叶盘溶液中钾(K)渗漏、紫外线吸收代谢物和电解质电导率(EC)增加。EB提高了幼苗中游离、半结合和结合形式的B的浓度。傅立叶变换红外光谱(FTIR)数据显示,EB诱导了蜡的不均匀沉积,改变了细胞壁的形状,降低了幼苗中纤维素的合成。EB影响酰胺I和酰胺II,表明蛋白质库受损。这些结果为理解EB对番茄幼苗不同大分子官能团的特异性影响提供了新的见解。

Pollination patterns i.e. the proportions of entomophilous, anemophilous, autogamous and hydrophilous plant species and those useful for the European honey bee (Apis mellifera L.) in the flora and vegetation of northern Croatia have been determined. The survey included 507 plant taxa, belonging to 95 plant families. The results show that most plant species depend on insect pollination (73.6%), followed by self-pollination (30%), wind (25%) and water pollination (0.6%). For some plant species there are one, two or more modes of pollination; the largest group consists of pure insect pollination (43%), followed by both insect and self-pollination (27%), pure wind pollination (22%), insect and wind pollination (2.6%), and so on. Overall, 54% of plant species useful to European honey bees were found, of which 51% provide pollen and 47% nectar. These results suggest that A. mellifera could be a potential pollinator for about half of the flora. Analysis shows significant differences in pollination patterns among habitat types and that most entomophilous plant taxa are found in grassland, forest and ruderal sites, indicating that these habitats are most important for pollinators. Other characteristics of plant species, such as flowering time, plant family, life form and origin, were also analysed to determine a possible relationship with pollination.
已经确定了授粉模式,即在克罗地亚北部的植物区系和植被中,昆虫性、海葵性、自花性和亲水性植物物种以及对欧洲蜜蜂有用的植物物种的比例。调查包括507个植物分类群,隶属于95个植物科。结果表明,大多数植物物种依赖昆虫授粉(73.6%),其次是自花授粉(30%)、风花授粉(25%)和水花授粉(0.6%);最大的一组包括纯昆虫授粉(43%),其次是昆虫和自授粉(27%)、纯风授粉(22%)、昆虫和风授粉(2.6%)等。总体而言,发现了54%对欧洲蜜蜂有用的植物物种,其中51%提供花粉,47%提供花蜜。这些结果表明,A.mellifera可能是大约一半植物群的潜在传粉昆虫。分析表明,不同生境类型的授粉模式存在显著差异,大多数昆虫学植物类群分布在草地、森林和荒地,表明这些生境对传粉昆虫最为重要。还分析了植物物种的其他特征,如开花时间、植物科、生命形式和起源,以确定与授粉的可能关系。

The first occurrence of Sporobolus indicus in Hungary is reported. The neotropical S. indicus is one of the oldest introduced neophytes to Europe. From the middle of the 19th century until the last decade of the 20th century, apart from a few occasional occurrences, it expanded only in the Mediterranean area. However, the number of observations has dramatically increased in the past two decades, even outside the Mediterranean region. Its recent rapid spreading is evident along roads, in lawns, trampled tourist places (e.g., campsites). Tourism certainly contributes to the very successful recent spreading of the species. Still, global warming, the increasingly mild winters in continental Europe, can certainly enhance the establishment and further dispersal of this cold sensitive species.
报道了印度孢子虫在匈牙利的首次出现。印度新热带S.indicus是欧洲最古老的新植物之一。从19世纪中期到20世纪最后十年,除了偶尔发生的事件外,它只在地中海地区扩张。然而,在过去二十年中,即使在地中海地区以外,观测次数也急剧增加。它最近的快速传播在道路、草坪、被践踏的旅游场所(如露营地)都很明显。旅游业无疑有助于该物种最近的成功传播。尽管如此,全球变暖,欧洲大陆日益温和的冬天,肯定会加强这种对寒冷敏感的物种的建立和进一步扩散。

The effects of foliar application of 5 mM arginine (Arg) on the growth and control of salinity-induced osmotic and oxidative stresses (0, 200, 400 and 600 mM NaCl) in Salicornia europaea seedlings were investigated. Despite higher levels of lipid peroxidation, lower membrane stability index (MSI), decreased pigment content and phenolic compounds, and reduced activity of antioxidant enzymes observed under salinity, seedling growth indices, including plant height and biomass, increased significantly, and some protective and antioxidant molecules such as proline and flavonoids accumulated. Soluble protein level increased at the low salt concentration (200 mM) but decreased at other doses. Exogenous Arg treatment alone had less or no effect on plant biomass and other metabolites, but in combination with salt, further enhanced growth parameters, MSI and accumulation of soluble protein, phenolic compounds and proline. Arg-induced changes under salinity were associated with decreased lipid peroxidation, flavonoids content and antioxidant enzymes activity. These results show that S. europaea seedlings are well tolerant to applied salt doses. The treatment with exogenous Arg alone affects plant growth slightly, but in combination with salt, synergistically increases growth and salt tolerance of these plants by enhancing the accumulation of proline and antioxidant molecules instead of enzymatic antioxidant.
研究了叶面施用5 mM精氨酸(Arg)对海蓬子幼苗生长和控制盐度诱导的渗透和氧化胁迫(0、200、400和600 mM NaCl)的影响。尽管在盐度下观察到脂质过氧化水平较高,膜稳定性指数(MSI)较低,色素含量和酚类化合物降低,抗氧化酶活性降低,但幼苗生长指数(包括株高和生物量)显著增加,一些保护性和抗氧化分子如脯氨酸和类黄酮积累。可溶性蛋白水平在低盐浓度(200mM)下增加,但在其他剂量下降低。外源Arg单独处理对植物生物量和其他代谢产物的影响较小或没有影响,但与盐联合处理,进一步提高了生长参数、MSI和可溶性蛋白、酚类化合物和脯氨酸的积累。Arg在盐度下引起的变化与脂质过氧化、黄酮含量和抗氧化酶活性降低有关。这些结果表明,S.europaea幼苗对施用的盐剂量具有良好的耐受性。单独用外源精氨酸处理对植物生长略有影响,但与盐结合,通过增强脯氨酸和抗氧化分子的积累而不是酶促抗氧化剂,协同提高这些植物的生长和耐盐性。

Research into the floristic and ecological characteristics of grasslands in the Zagreb area was conducted in June and July 2020. Eight localities were processed, each containing two 1m2 plots. The floristic composition of each quadrat was analysed and the presence of two vegetation communities, Festuco-Brometea and Molinio-Arrhenatheretea, was determined. Although indigenous taxa dominate, two invasive plants: Echinocystis lobata (Michx.) Torr. et A. Gray and Erigeron annuus (L.) Desf. have been recorded. Based on the functional traits of taxa, the functional diversity of plots was calculated and compared with the number of taxa and the weight of plant biomass collected within the plots. Functional diversity values ranged from 1.121 to 2.060 and dry biomass from 251.4 to 586.8 g m-2 per quadrat. Correlation analyses linked a decrease in the number of taxa and functional diversity with an increase in biomass and specific leaf area. Functional diversity is positively correlated with the number of taxa, plant dry matter content and leaf dry matter content. It is necessary to conduct this type of research in other grassland communities in Croatia to obtain more detailed insights into the relations of these parameters.
2020年6月和7月对萨格勒布地区草原的植物区系和生态特征进行了研究。八个地点被处理,每个地点包含两个1m2的地块。分析了各样方的区系组成,确定了Festuco-Brometea和Molinio-Arrhenatheretea两个植被群落的存在。尽管本地分类群占主导地位,但两种入侵植物:棘囊藻(Echinocystis lobata)。托。et A. Gray和Erigeron annuus (L.)Desf。都有记录。根据分类群的功能特征,计算样地的功能多样性,并与样地内的分类群数量和植物生物量生物量进行比较。功能多样性值为1.121 ~ 2.060,干生物量值为251.4 ~ 586.8 g m-2 /样方。相关分析表明,类群数量和功能多样性的减少与生物量和比叶面积的增加有关。功能多样性与类群数量、植物干物质含量和叶片干物质含量呈正相关。有必要在克罗地亚的其他草原群落中进行此类研究,以更详细地了解这些参数之间的关系。

A new species, Blitum venetum Iamonico, Argenti, Sciuto & Wolf is described from the Dolomites Massif (North-Eastern Italy) on the basis of molecular analyses (nuclear ITS and plastid trnL-F regions) and morphological investigation. The new species is similar to B. bonus-henricus and B. californicum, but it differs from these taxa by characters of leaves (width, pubescence, and margins), inflorescence (presence of bracts), perianth segments (colour), and seeds (diameter, colour, and seed testa ornamentation). Moreover, in phylogenetic reconstructions B. venetum results as clearly separated from the other species of the genus; this finding was further strengthened by the nucleotide divergences calculated between the sequence of the type specimen and other Blitum taxa, which are comparable with the interspecific divergences calculated inside this genus.
在分子分析(核ITS和质体trnL-F区)和形态学研究的基础上,描述了意大利东北部多洛米蒂地块的一个新种,即Blitum venetum Iamonico、Argenti、Sciuto和Wolf。该新种与B.bonus henricus和B.californicum相似,但在叶(宽度、短柔毛和边缘)、花序(存在苞片)、花被片(颜色)和种子(直径、颜色和种皮装饰)的特征上与这些分类群不同。此外,在系统发育重建中,B.venetum与该属的其他物种明显分离;模式标本序列和其他Blitum分类群之间计算的核苷酸差异进一步加强了这一发现,这些差异与本属内部计算的种间差异相当。

Morphological and nomenclatural investigations for two critical Mediterranean species of Elatine, i.e., E. macropoda and E. gussonei, aswell as their correct distribution in Sicily, are discussed. These two names are lectotypified on herbarium specimens kept, respectively, at NAP and FI. The morphological investigations carried out on both the types, as well as on several living and dried material collected in southern Sicily, Lampedusa, and Malta (loci classici included), allowed to individuate reliable diagnostic characters that can be used for a correct identification of the two species. The most relevant differential features are: ratio petal/sepal, size and shape of the seedtesta pits, and their arrangement in row number. According to our results, only E. macropoda occurs in the Hyblaean territory (Sicily), which is the locus classicus, whereas E. gussonei occurs on Lampedusa and Maltese islands only. However, further and in-depth morphological research is necessary to clarify their overall distribution in the Mediterranean area. Finally, an analytic key to the Mediterranean Elatine is provided.
本文讨论了地中海两个重要的类人猿种——巨足猿和古索奈猿的形态和命名研究,以及它们在西西里岛的正确分布。这两个名字分别在NAP和FI保存的植物标本室标本上进行了选型。对这两种类型进行的形态学调查,以及在西西里岛南部、兰佩杜萨岛和马耳他(包括经典位点)收集的几种活的和干燥的材料,允许对可靠的诊断特征进行个性化,可以用于正确识别这两个物种。最相关的差异特征是:花瓣/萼片比、种皮坑的大小和形状以及它们在行数上的排列。结果表明,大足鄂鼠只分布在西西里岛的海布拉海地区,是典型地,而古索内鄂鼠只分布在兰佩杜萨岛和马耳他岛。然而,需要进一步深入的形态学研究来阐明它们在地中海地区的总体分布。最后,给出了分析地中海拉丁语的关键。

Some Dianthus specimens collected from Sakarya and Bolu Provinces (Turkey) provinces are proposed as a new species. Dianthus nezahatiae Hamzaoğlu (Caryophyllaceae) is naturally distributed in subalpine meadowhabitats between the altitude range of 1450 and 1620 m a.s.l. Dianthus nezahatiae is differed from D. akdaghensis Gemici et Leblebici in respect to its inner bracts are 1.7−2.1 mm wide, the apex of the epicalyx scales is attenuate–rounded, the petal collar is almost half ofthe claw width, and the capsule is longer than calyx. In this paper description of the species, comparison with its close taxon, photographs, the distribution map, and its habitat preference are given.
