The article presents the results of a long-term of study of biological features of 54 sorts of Clematis L. genus of collection of the SouthUral Botanical Garden-Institute of UFRC RAS. The aim of the work was to summarize the introduction studies for the possibility of successful use of clematis sorts in vertical gardening in the Bashkir Cis-Urals and adjacent territories. During the period 2007 and 2015, the seasonal rhythm of growth and development and vegetative reproduction were studied, and the prospects of introduction and introduction resistance under the culture were assessed. The length of the clematis growing period varies from 156 to 168 days. The duration of flowering of sorts is 24–111 days. Rooting of clematis sorts using root-forming stimulators is 33 to 100%. The largest number of rooted cuttings was obtained using the preparation “Circon”. According to the results of the introduction success assessment, all the studied sorts have high resistance to local climatic conditions.

Обґрунтовано необхідність всебічного вивчення та вирощування енергетичних культур на маргінальних землях в умовах України для отримання біопалива. Наведено біолого-морфологічну характеристику та ілюстративний матеріал енергетичних культур з родини тонконогових. Розуміння морфолого-біологічних особливостей та відношення енергетичних культур до умов навколишнього середовище дасть змогу раціонально розміщувати їх у певних ґрунтово-кліматичних зонах України, підбирати оптимальні елементи технології вирощування. Це забезпечить умови, близькі до сприятливих для росту і розвитку рослин, та дозволить отримувати велику, енергоємну фітомасу. Визначено, що найбільшу врожайність сухої маси формує арундо тростинний та міскантус гігантський, меншу – сорго багаторічне та просо прутоподібне за багаторічного циклу вирощування в ґрунтово-кліматичних умовах, що відповідають їх біологічним особливостям. Урожай фітосировини енергетичних культур доцільно використати для виробництва біопалив та отримання енергії. The article substantiates the necessity of comprehensive study and cultivation of energy crops on marginal lands in the conditions of Ukraine for obtaining biofuel. Biological and morphological characteristics and illustrative material of energy cultures from the family of fine-toned ones are presented. Understanding the morphological and biological features and the ratio of energy crops to environmental conditions will allow them to be placed rationally in certain soil and climatic zones of Ukraine, and to select the optimal elements of growing technology. This will ensure conditions close to those favorable for the growth and development of plants, and will allow obtaining a large, energy-intensive phytomass. The harvest of the phytocoagulants of energy crops is expedient for use in the production of biofuel and energy production.

It is established that milk mares of the Kazakh horse of the Aday breed have on average live weight of 389.2 kg, height at the withers of 139.2 cm, an oblique body length of 142.1 cm, a chest girth of 167.6 cm and a metacarpus girth of 17.5 cm. Mares of the Kazakh breed of the Mangystau population surpass in the live weight and body measurements the peers of Aday offspring. Namely, the live weight was 415.3 kg, the height at withers – 140.9 cm, the oblique body length – 143.4 cm, the chest girth – 170.5 cm and the metacarpus girth - 18.3 cm. In general, mares of the Kazakh horse of the Aday offspring are inferior to the minimum requirements for animals of the elite class in height at withers, the chest and metacarpus girths. At the same time, 90% of mares correspond to the 1 quality class. In stallions – producers of the Kazakh horses of the Aday offspring, the live weight averaged 438.7 kg, and in stud horses the Mangystau population – 449,8 kg. Body measurements in Aday horses were 145.2-147.5-169.8-18.5 cm, in the Mangystau population – 145.6-148.1-172.2-18.5 cm, respectively. Some regularities of growth and development of foals from birth to 30 months of age are established. A scale for the development of young Aday horses has been developed.

Cell and tissue interactions are a basic aspect of eukaryotic growth and development. While cell-to-cell interactions involving recognition and incompatibility have been studied extensively in animals, there is no known antigen-antibody reaction in plants and the recognition mechanisms operating in plant grafts have been virtually neglected.An ultrastructural study of the Sedum telephoides/Solanum pennellii graft was undertaken to define possible mechanisms of plant graft incompatibility. Grafts were surgically dissected from greenhouse grown plants at various times over 1-4 weeks and prepared for EM employing variations in the standard fixation and embedding procedure. Stock and scion adhere within 6 days after grafting. Following progressive cell senescence in both Sedum and Solanum, the graft interface appears as a band of 8-11 crushed cells after 2 weeks (Fig. 1, I). Trapped between the buckled cell walls are densely staining cytoplasmic remnants and residual starch grains, an initial product of wound reactions in plants.

Calcium is an important element in the growth and development of plants and one form of calcium is calcium oxalate. Calcium oxalate has been found in leaf seed, stem material plant tissue culture, fungi and lichen using one or more of the following methods—polarized light microscopy (PLM), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and x-ray diffraction.Two methods are presented here for qualitatively estimating calcium oxalate in dried or fixed tobacco (Nicotiana) leaf from different stalk positions using PLM. SEM, coupled with energy dispersive x-ray spectrometry (EDS), and powder x-ray diffraction were used to verify that the crystals observed in the dried leaf with PLM were calcium oxalate.

Cytokinins are plant hormones that play a large and incompletely understood role in the life-cycle of plants. The goal of this study was to determine what roles cytokinins play in the morphological development of wheat. To achieve any real success in altering the development and growth of wheat, the cytokinins must be applied directly to the apical meristem, or spike of the plant. It is in this region that the plant cells are actively undergoing mitosis. Kinetin and Zeatin were the two cytokinins chosen for this experiment. Kinetin is an artificial hormone that was originally extracted from old or heated DNA. Kinetin is easily made from the reaction of adenine and furfuryl alcohol. Zeatin is a naturally occurring hormone found in corn, wheat, and many other plants.Chinese Spring Wheat (Triticum aestivum L.) was used for this experiment. Prior to planting, the seeds were germinated in a moist environment for 72 hours.

Ethylene Signalling

Ethylene is the simplest unsaturated hydrocarbon, yet it has profound effects on plant growth and development, including many agriculturally important phenomena. Analysis of the mechanisms underlying ethylene biosynthesis and signalling have resulted in the elucidation of multistep mechanisms which at first glance appear simple, but in fact represent several levels of control to tightly regulate the level of production and response. Ethylene biosynthesis represents a two-step process that is regulated at both the transcriptional and post-translational levels, thus enabling plants to control the amount of ethylene produced with regard to promotion of responses such as climacteric flower senescence and fruit ripening. Ethylene production subsequently results in activation of the ethylene response, as ethylene accumulation will trigger the ethylene signalling pathway to activate ethylene-dependent transcription for promotion of the response and for resetting the pathway. A more detailed knowledge of the mechanisms underlying biosynthesis and the ethylene response will ultimately enable new approaches to be developed for control of the initiation and progression of ethylene-dependent developmental processes, many of which are of horticultural significance.

The Clinical Fellowship Experience is described by the American Speech-Hearing-Language Association (ASHA) as the transition period from constant supervision to independent practitioner. It is typically the first paid professional experience for the new graduate, and may be in a setting with which the new clinician has little or even no significant practical experience. The mentor of a clinical fellow (CF) plays an important role in supporting the growth and development of this new professional in areas that extend beyond application of clinical skills and knowledge. This article discusses how the mentor may provide this support within a framework that facilitates the path to clinical independence.
