Developmental Performance

Although salep orchids are annual plants, each new generation emerges larger than their parents. There are no data on the developmental performance of these species that cannot be cultivated due to production difficulties. This study discusses Salep vomeracea (Burm. f.) Briq., one of the most common species in temperate climate regions. Tubers obtained from natural flora were divided into seven groups according to their size. Morphological characteristics of the seedlings developed from these tubers were determined and observed up to the harvest stage. The study was carried out in a randomized plot design with three replications and for two years. As a result of statistical analysis, all parameters were found to be significant. The canonical correlation between the first pair of canonical variables was 0.995 (p<0.01). The data obtained from the length of the planted tuber made the biggest contribution to the explanatory power of the canonical variables. Additionally, the mathematical relationship between width, height and area values of salep leaves was determined.

Abstract: The objective of this work was to evaluate the biometry of fruit and seed, and the diversity of paradise nut (Lecythis pisonis) genotypes. Fruit of 12 paradise nut genotypes were collected from plants in the northern region of the state of Espírito Santo and in the eastern region of the state of Minas Gerais, Brazil. Data were subjected to the analysis of variance, and means of the different genotypes were compared by Scott-Knott’s mean clustering test. The phenotypic diversity was analyzed using Mahalanobis’ generalized distance, and clustering, by Tocher’s optimization method and the graphical dispersion of canonical variables. The relative contribution of the characters to diversity was assessed by Singh’s method. The paradise nut genotypes differed regarding the morphological characteristics of fruit and seed. Genotype 1 produced the largest number of seed per fruit, and genotypes 2 and 7 produced the largest seed. These genotypes were clustered into different groups, which is indicative of their potential combination for use in genetic breeding programs.

AbstractBlood parasites of Apodemus agrarius were investigated in Eastern Slovakia during 1998–2005. The following parasitic species were detected: Trypanosoma grosi, Babesia microti-like piroplasms and Bartonella sp. Trypanosoma grosi was the most common species, with an infection prevalence of 12.7%. Trypanosomes were morphologically typical of the lewisi group, however, they were bigger than T. grosi described in A. flavicollis and A. sylvaticus. The differences analysed by nested analysis of variance were statistically significant. Pleomorphism was not observed. Infections with piroplasms were detected only at two sites, with an intensity of infection not exceeding 0.1%. The morphology of the piroplasms was different from those typical of B. microti. Bartonella occurred at two sites in 0.81% of the animals sampled. The prevalence of infection had a seasonal pattern throughout the study years. Trypanosomes occurred from July to November, with a peak in September, piroplasms occurred in May and June, and Bartonella sp. from May to July.

The aim of this study was to assess the prevalence of denture-related stomatitis (DRS) in different attachment-retained overdenture wearers and its association with particular colonizing Candida species. Thirty-seven edentulous patients with implant-supported maxillary or mandibular overdentures were enrolled. A full clinical history was obtained, including details of patients' oral hygiene practices and the levels of erythema based on Newton's classification scale. Swabs were taken from the palate and investigated mycologically to identify the yeast colonies. Quantitative and qualitative microbiological assessments were performed, which included recording the total numbers of colonies (cfu), their color, and their morphological characteristics. Significant differences were found in cfu values between the attachment and inner surfaces of locator- and bar-retained overdentures (P &lt; .05). Candida albicans was the most common species in both evaluations, being isolated from 81.3% of bar-retained overdentures and 38.1% of locator-retained overdentures. DRS developed in all patients using bar-retained overdentures but in only 71.4% of those using locator-retained overdentures. No statistically significant relationship was found between bar and locator attachments according to smoking habit, overnight removal, or plaque and gingival indices (P &gt; .05).

Cinnamomum kanehirae, a native tree of Taiwan, is an important tree that hosts popular medicinal fungi. In the winter of 2011, zonate leaf spots were observed at a nursery garden in Wu-Lai, Taiwan. Initial symptoms included small brown lesions on leaves that became larger leaf spots after expanding or fusing together, causing a leaf blight and eventually defoliation. Sporophores on the host were generally hypophyllous but sometimes amphigenous, solitary, erect, easily detachable. The upper portion of the sporophore was considered an individual conidium and consisted of a pyramidal head that was fusiform to ventricose, 320 to 580 μm long and 100 to 130 μm wide at the broadest point. Branches within the pyramidal head were short and compact, and dichotomously or trichotomously branched. The sporophore initials were hyaline, broad, septate, tapering toward an acute apex, and sometimes constricted at the basal septum. Sclerotia were observed in older lesions, grey or black, spherical, and 1 to 2.5 mm in diameter. The fungus was isolated from infected tissue and sporophores, maintained on potato dextrose agar (PDA) at 20°C in darkness. Sclerotia were produced on PDA after 4 to 5 weeks and were irregular or spherical, but sporophores didn't develop on agar medium. The fungus was identified as Hinomyces moricola on the basis of morphological characteristics (1). Koch's postulates were performed by inoculating four 1-year-old, asymptomatic, potted C. kanehirae plants; every plant was inoculated with sporophores from infected leaves on each of five leaves. Four noninoculated plants were kept in separate pots and served as controls. All plants were covered with transparent plastic bags individually and incubated in a growth chamber at 18 to 20°C. Symptoms were observed after 2 to 4 days on every inoculated plant but not on uninoculated plants. The leaf spots were similar to those originally observed. The pathogen was reisolated from spots of inoculated plants. The pathogenicity test was repeated once. H. moricola is known to cause severe defoliation on woody and annual plants, including at least 73 host species and 36 families distributed in the eastern United States and Japan (2).

This study was carried out in order to investigate the natural occurrence of toxigenic fungi and levels of zearalenone (ZEA), deoxynivalenol (DON) and aflatoxin B1 (AFB1) in the maize stored immediately after harvesting in 2016 and used for animal feed in Serbia. A total of 22 maize samples were collected from four different districts across the country: City of Belgrade (nine samples), Sumadija (eight samples), Podunavlje (four samples) and Kolubara (one sample). Toxigenic fungi were identified according to the morphological characteristics whereas the mycotoxins contamination were detected using biochemistry enzyme-linked immuno-sorbent (ELISA) assay. The tested samples were mostly infected with Aspergillus, Fusarium and Penicillium spp., except that one sample originated from Kolubara was not contaminated with Aspergillus species. Fusarium graminearum was the most common species in the maize sample from Kolubara district (60%), F. verticillioides in the maize samples from Podunavlje (43.75%) and City of Belgrade (22.4%) districts, and Penicillium spp. in the maize samples from Sumadija district (26.38%). In the analysed maize samples the presence of Aspergillus species was low (0-1.78%). Mycotoxicological analysis revealed the presence of zearalenone (ZEA), deoxynivalenol (DON) and aflatoxin B1 (AFB1) in all the investigated samples, except that DON and AFB1 were not recorded in the samples from Podunavlje and Kolubara districts, respectively. The investigated samples were highly contaminated with ZEA, with incidence of 100% for the samples from Sumadija, Podunavlje and Kolubara districts and 88.89% for the samples from City of Belgrade district. In addition, the samples contamination with DON was 100% and 22.2% for the samples from Sumadija, Kolubara and City of Belgrade, districts, respectively. The highest number of AFB1 positive samples was found in Sumadija district (87.5%), while in the City of Belgrade and Podunavlje districts, 55.56% and 50% AFB1 positive samples were established, respectively. Generally, remarkable infection of all the tested samples with toxigenic fungal species from Aspergillus, Fusarium and Penicillium genera were recorded. In addition, high contamination with mycotoxins ZEA, DON and AFB1 were also recorded; nevertheless, only in one sample the level of DON exceeded the allowed legal limit (1750 ?g kg-1) according to Regulation for unprocessed maize. Therefore, permanent mycological and mycotoxicological analyses of maize grain are necessary for risk assessment of fungal and mycotoxin contamination throughout the food chain.

Introduction: Atopic dermatitis is a chronic, recurrent inflammatory skin disease that is characterized by an eczematous reaction. Few studies have investigated fungi in the pathogenesis of atopic dermatitis, however, there are different about distribution of Malassezia species. Objectives: To indentificate of Malassezia species and its asociation with clinical manifestations in Vietnamese atopic dermatitis patient. Methods: 178 patients who were diagnosed with atopic dermatitis and had a postitive direct examination of Malassezia at the National hospital of dermatology and venereology between July 2019 and June 2020.  Specimens were taken with cellotape, then stained in 20% of potassium hydroxit combined with ParkerTM blue black ink.  All patient who had postive test were cultured on SDA and mDixon. For fungal samples, we selected pure colonies with morphological characteristics of yeast as follows about 1cm in diameter, round, cream or milky in color, smooth and glossy to detect the species. Results: From the samples of atopic dermatitis patients, we cultured and idenfified 41 cases. 5 species were found, in which M. globosa was the most common species, accounting for 39%, followed by M. restricta (19.5%), M. dermatis (17.1%),  M. furfur (17.1%) and M. sympodialis (2.4%). Conclusion: On the skin lesions of Vietnamese patients with atopic dermatitis, M. globosa was the most common species with 39.0%.

The Relationship

In this study, we use canonical correlation analysis to interpret the relationship between water quality parameters (T, Alk, Cl, EC, TN, TP, UV-254, pH, HPC, DO) and primary productivity parameters (algae and chlorophyll-a). In these two sets of constructed canonical variables, the water quality parameters can account for 39.25% of the total variance of primary productivity. The majority of the explanatory power is from the first set of canonical variables, which has a correlation coefficient of 0.84. The main factors that control chlorophyll-a are HPC, Alk, T, TN, and pH.

New Generation

In the early 1990s a new generation of scholars has tackled matters of feminist perspectives on war, peace, and specifically the academic discipline of international relations. A similar confrontation between traditional scholarly themes and gender-sensitive analyses within critical geopolitics is now obviously necessary. Although authors such as Cynthia Enloc have written about global politics and the role of women in international relations in ways that are sensitive to the geographic dimension, many theoretical and practical implications of a gender-sensitive approach to geopolitics remain to be worked out. In this paper I argue that, among other issues, investigating the gendered assumptions in the study of international relations and foreign policy-making, in addition to more explicitly geopolitical reasoning, shows how political spatialisations render women vulnerable. In addition, examining the implications of militarised definitions of (territorial) citizenship, the use of masculinist notions of power, space, and security, and the representation of women in global conflicts, sheds light on the ‘taken-for-granted’ spatial aspects of the routine operation of power. By enlarging the scope of critical geopolitical analysis, greater attention to gender issues enhances the explanatory power of ‘big picture’ political geography, not least by focusing on the practical everyday implications of geopolitics for those who are so often written out of its scripts.

<p>Anatomical-morphological characteristics of leaves and stems of plants of succulent type <em>Crassula perforata</em> Thunbg., <em>C. socialis</em> Schonland (Crassulaceae), <em>Senecio rowleyanus</em> Jacods, and <em>S. herreianus </em>Moritz Kurt Din. (Asteraceae) from extreme habitats were studied. Basic quantitative parameters of anatomical indices were presented. The comparative analysis of the structure of vegetative organs of succulents was carried out. Several common features, which result from adaptation to such conditions of growth (characteristic peculiarities of the external structure, weak differentiation of mesophyll, considerable development of the water-bearing tissue) and features, which distinguish the studied species (the type of leaf mesophyll, presence of trichomes, type of the stomata apparatus, the degree of the conductive system development) were registered. The species which we studied is mainly spread in arid regions with warm climate and is capable of special САМ – type of photosynthesis, which enables it to survive under conditions of water deficiency and high temperature stress. In addition, arrangement of leaves in rosette makes it possible for the latter to shadow the other ones and condense moisture near the stem base. However, it can be seen from our research that under conditions of temperate climate plants, studied by us, preserved the anatomical structure, typical of tropical representatives from xeric habitats and have similar survival strategy, which is manifested at all levels of organisation: morphological, anatomical and physiological.</p>

The study was carried out with the objective of verifying the effect of the bacterium Azospirillum brasilense in the behavior of the morphological characteristics of cultivars soybean submitted to drought stress. Two experiments were carried in randomized blocks with a split-split plot design, with four replications. We evaluated the cultivars TMG 132 and ANTA 82. The treatments were subjected to two irrigation depths: total irrigation (100% of crop evapotranspiration) and irrigation with drought stress (25% of crop evapotranspiration) and co-inoculated with Azospirillum brasilense and inoculated whit only Bradyrhizobium japonicum. The coefficients of the correlation between the characteristics: leaf area, plant height, root length, number of nodules, shoot dry matter, root dry matter and nodule dry matter were analyzed, as well as the effects over the productivity through the path analisys. The drought stress did not alter the correlations between the studied characteristics; however the alteration happened due to the inoculation method. The path analysis showed that the root length was the only variable that had a direct effect on soybean grain yield, and this occurred only inoculation. In the co-inoculated treatments with Azospirillum brasilense, there were greater indirect effects in grain yield due the root dry matter and shoot dry matter.
