Opis:
Heavy metals are some of the environmental pollutants that have a serious impact on the environment. The analysis of hydromacrophytes growing in small rivers of the south of Kazakhstan with different contents of heavy metal salts revealed that the morphometric indicators of the same plant species differ significantly, depending on the level of total mineralization of the aquatic environment in different rivers of the Turkestan region. It has been established that two plant species can be used to bioindicate the content of lead ions in the aquatic environment: Azolla caroliniana Willd. and Veronica beccabunga L., which must be introduced into the tested aqueous solutions in the amount of 1.0 kg/m3 and 1.5–2.0 kg/m3, respectively, to fully cover the water column at different depths. The first morphological changes in plants, in the form of destruction of the structure of chloroplasts along the edges of unfolded leaves in A. caroliniana Willd. and slight withering of the lower underwater leaves in V. beccabunga L., occur already at a 1.5 mg/l Pb2+ content in water, and a further increase in the content of lead ions in water to 600.0–800.0 mg/l leads to the death of plants.

Opis:
The establishment of certain morphological, physical and physiological criteria was considered and this might allow us to determine more precisely the maturation degree as well as the optimum harvest and sowing period of seeds. The criteria for assessing the maturation degree of seeds presented earlier (the completely formed embryo, the prominent endosperm with a normal consistency) can now be completed with a new criterion, namely the one referring to the slight tendency of the seesds tegument to get yellow. This is due to the fact that the seed completes its growing sooner than the pericarp. The fact was proved both by the greater decrease the fresh mass of the pericarp than that of the seed and by the greater decrease of the moisture content of the seed than that of the pericarp during the four examined ripening phases.

Opis:
In this study, we present investigations of morphological changes in the inflorescence of bolting Allium sativum L., which forms umbel-like inflorescences with small, inconspicuous flowers, bulbils, and leaf-like membranous bracts. Particular attention was focused on the architecture of a single flower, and the full sequence of developmental events and the differentiation of flower elements and inflorescence were traced. During the several-year long investigations of the garlic species, we observed that all inflorescence elements emerged chaotically, taking a completely random place in the inflorescence receptacle and it was impossible to identify the sequence of formation of the individual inflorescence elements. The absence of regular phyllotaxis and the specific sequence of formation of inflorescence elements are characteristic for inflorescence reversion. Since domesticated garlic has lost the capacity for sexual reproduction, it has probably evolved alternative reproduction modes in its developmental strategy, which is reflected by the formation of numerous bulbils (vegetative buds, topsets) in the inflorescence. This is one of the forms of reproductive strategy of the species, which through domestication progresses from sexual to asexual reproduction.

Opis:
Background and Aims: Leaf morphology, anatomy, degree of lignification, and tensile strength were studied during vegetative phase change in an inbred line of Zea mays (OH43 x W23) to determine factors that influence mechanical properties during development. Methods: Tensometer, light microscopy, histochemistry. Key results: Mature leaf length increased linearly with plant development, peaked at leaves 7 and 8 (corresponding to the onset of the adult phase) and then declined. Leaf width was stable for leaves 1 through 3, increased to leaf 7, remained stable to leaf 10, and then declined through leaf 13. Lamina thickness was highest for leaf 1 and decreased throughout development. Leaf failure load to width ratio and failure load to thickness ratio increased with development suggesting that changes in leaf morphology during development do not entirely account for increases in failure load. Histochemical analyses revealed that leaf tensile strength correlates with percent lignification and the onset of anatomical adult features at various developmental stages. Conclusions: These data demonstrate that in Zea mays lignification of the midrib parenchyma and epidermis may be directly correlated with increased tensile strength associated with phase change from juvenility to adulthood. Failure load and resultant tensile strength values are primarily determined by the percent tissue lignification and the appearance of leaf architectural characters that are associated with the transition from the juvenile to the adult phase. Increased mechanical stability that occurs during the phase transition from juvenility to adulthood may signify a fundamental change in strategy for an individual plant from rapid growth (survival) to reproduction.

This article presents a review of the research conducted to date into the coexistence of malocclusions and phonation disorders, as well as the results of research conducted by the authors of the article. It is an attempt at providing answers to the following questions: are phonation disorders related to specific malocclusions, what specific phonation disorders accompany specific occlusal problems, does a single problem condition another occlusal problem?Detailed study of this subject will provide a concise compilation of knowledge for experts in many areas, including speech-language pathology, orthodontics, paediatrics, otolaryngology and phoniatrics. The article presents a specific approach to occlusion, namely from the speech-language pathology point of view. The authors have associated phonation disorders with specific malocclusions.Numerous clinical trials are necessary to investigate this phenomenon, to research the above mentioned dependence and identifying the relations between malocclusions and phonation disorders. The article presents the results of the research carried out by the authors together with results of surveys undertaken by professionals dealing with the impact of malocclusions on phonation disorders over the years.

Opis:
Thrips nigropilosus Uzel is a polyphagous species occurring mainly in temperate climates. Its life cycle depends on photoperiodic and temperature conditions. T. nigropilosus feeds on different plant species, but it is considered one of the most serious pests of pyrethrum plants causing serious economic problems. However, several additional agricultural host plants have been affected by T. nigropilosus, including spearmint, cucumber, and lettuce, indicating that this insect can significantly widen its habitats and occurs especially frequently in greenhouses. We report that T. nigropilosus massively attacked Mentha × piperita L. cultivated in greenhouses in central Poland and destroyed the entire mint crops within a short time. The study provided insight into the harmful effect of the thrips and showed that the length of the thrips developmental cycle was reduced with temperature increases from 18 to 26.6°C. The lower threshold temperatures were 13.7, 10.2, 5.0, and 10.1 for eggs, larvae, pupae, and total development, respectively, and the thermal constant for the same developmental stages was 65.9, 90, 132.5, and 284.9-degree days. Both parameters were estimated by linear regression analysis. During our experiment, T. nigropilosus developed by thelytokous parthenogenesis. The morphological and anatomical changes in damaged plants were associated with the fact that the insect began feeding on the lower lamina surface close to the leaf midribs, but no damage to vascular bundles and glandular cells was observed.

Introduction: In order to prevent increased bacterial resistance, it is important to use herbal medicines with less side effects. Objective: In this study, the chemical composition, antimicrobial, antioxidant activities and SEM images of Lavandula officinalis and Origanum onites oils obtained in two different ways were determined. Methods: The antimicrobial activity of the oils was determined against reference and multiple strains of foodborne and pathogenic bacteria. The each essential oil sample were analyzed by GC–MS. Antioxidant activities of the samples were examined through DPPH• and ABTS•+ radical scavenging and FRAP assays. Results: The results indicate that the oils of obtained from Origanum onites and Lavandula officinalis exhibited relatively strong antibacterial and antifungal activity. In addition, the antioxidant activities detected were remarkable. Morphological changes in bacterial cells treated with essential oil samples were demonstrated with SEM images. In addition, the chemical components of the oil samples obtained by both water steam and cold press were revealed by GC-MS analysis and compared. Conclusion: When all the obtained results are evaluated together; these plants could be suitable for using as antimicrobial and antioxidative agents in several industries such as food, cosmetic, etc.
