The results of research on the effect of crop protection agents on tomato and soybean crops under Primorye conditions are presented. The study of preparations was carried out on zoned varieties of tomato Novichok and soybean Primorskaya 86. The effectiveness of different combinations of biological preparations based on Bacillus subtilis strains Bactophyt, Gamair and growth regulators Zircon, Mival-Agro was evaluated. The preparations were used for seed treatment and spraying of vegetative plants. Complex treatment with Bactofit provided a 3.9% reduction of septoriosis manifestation on tomato, the biological efficiency was 22.1%. Growth regulator Mival-Agro (seed and plant treatment) provided 36.8% effectiveness against late blight. The highest tomato yield was observed with the treatment of seeds and plants with Gamair (20.0 t/ha) with an increase of 4.9 t/ha compared to the control. The maximum efficiency (29.7%) against septoriosis on soybeans was recorded in the variant Gamair + Mival-Agro. The biological efficacy against peronosporosis ranged from 21% (Gamair complex treatment) to 25.4% (Bactofit + Mival-Agro). The application of all preparations had a positive effect on the growth and development of soybean plants. The largest increase in plant height in the phase of full ripeness was noted in the variant with the use of Bactofit and Mival-Agro (73.1 cm), in the control - 61.8 cm. Thousand-kernel weight increased with certainty by 13.5 – 22.0% in comparison with the control (176.2 g) after the usage of biopreparations and growth-regulating chemicals. High yield was achieved in the Bachtophit + Mival Agro variant (2.7 t/ha), in comparison the control was 1.8 t/ha, the addition amounted to 0.9 t/ha.

Introduction. Degenerative-dystrophic changes in the spine are the most common chronic human diseases. Pronounced clinical manifestations of vertebrogenic diseases are observed during active labor activity and represent one of the most frequent causes of temporary disability. It is also known that any pain syndromes are accompanied by the development of psychovegetative disorders, which reduces the effectiveness of treatment. In recent years, there has been a reasonable increase in the interest of the medical community to the non-drug treatment methods. It is caused by the polypharmacotherapy side effects, an increased numbers of allergic reactions, problems with polypragmasia, and a low level of compliance. At the same time, the question of the possibility of various non-drug treatment methods combining is quite acute.The goal of research is to substantiate the clinical effectiveness of the combined application of osteopathic correction and reflexotherapy in the complex treatment of patients with dorsopathy at the cervical-thoracic level.Materials and methods. A prospective controlled randomized study was conducted on the basis of the medical clinics of LLC «Family Health» (Kazan) and ANO «Center for SEB assistance» (Kazan) from April 2018 to May 2019. The study involved 52 people with dorsopathy at the cervical-thoracic level, aged from 25 to 45 years. In accordance with the exclusion criteria, 7 people dropped out of the study. The remaining patients (45 people), depending on the used treatment method, were divided by a simple randomization method using a random number generator into three groups of 15 people. The first group (main group) received osteopathic correction and reflexotherapyon the background of standard drug therapy; the second and the third groups (control groups) received only osteopathic correction orreflexotherapy, respectively, on the background of standard drug therapy. The osteopathic examination was performed for all patients regardless of the group, before and after the course of therapy, with the formation of an osteopathic conclusion.Also there was the estimation of the degree of pain syndrome severity,the asthenia, and the degree of accumulated emotional and energy charge that does not get out in a person.Results. It was found in the course of the study that the inclusion of osteopathic correction and reflexotherapy in the complex therapy of patients with dorsopathy at the cervical-thoracic level is clinically more effective than the isolated use of these methods. Such complex therapy allows to achieve a more significant reduction in the severity of the pain syndrome by VAS (p<0,05), relief of internal emotional tension (p<0,05), and increase the effectiveness of correction of dominant somatic dysfunction. Based on the obtained data, it could be assumed that reflexotherapy potentiates the effects of osteopathic correction.Conclusion. Based on the study, it can be concluded that the combination of osteopathic correction and reflexotherapy in the treatment of patients with dorsopathy at the cervical-thoracic level increases the clinical effectiveness of the standard drug therapy. At the same time, it is worth noting the potentiating effect of the combined use of two non-medicinal methods. The question of combining of various non-drug treatment methods is quite acute today, so this study will be continued.

A soja, Glycine max (L.) Merril, é uma das culturas de maior importância econômica para o Brasil, considerada uma commodity nacional devido à sua alta produtividade e participação nas exportações no mercado internacional. Dentre os insetos-pragas que causam danos para essa cultura, nos últimos anos agrícolas têm merecido destaque as lagartas de Spodoptera eridania (Cramer), as quais podem se alimentar tanto de folhas quanto das vagens das plantas de soja, causando prejuízos econômicos para os sojicultores, principalmente nas áreas do Cerrado localizadas na região Centro-Oeste do país. O objetivo da presente revisão é disponibilizar informações sobre os aspectos bionômicos de S. eridania, a fim de dar subsídios para futuras pesquisas sobre o manejo dessa praga.Bionomic Aspects of Spodoptera eridania (Cramer): A Pest in Expansion on Soybean Crop in the Region of Brazilian CerradoAbstract. Soybean, Glycine max (L.) Merril, represents one of the major economically important crops to Brazil, and is considered a national commodity because of its high yield and participation in international trade exportations. Among the insect pests that cause damage to this crop, Spodoptera eridania (Cramer) larvae highlighted in the last agricultural seasons by feeding on leaves and pods of soybean plants, and hence causing economical losses to soybean growers, especially in the Cerrado areas located in the Midwest region of the country. We aimed with this review to provide information about bionomical aspects of S. eridania in order to give subsides for further researches on the management of this pest.

Plant genetic diversity is the fundamental of plant-breeding programs to improve desirable characteristics. Hence, evaluation of genetic diversity is the first step in fruit-breeding programs. Accordingly, the current study was carried out to evaluate 25 superior walnut genotypes in respect of phenotypic and cytological characteristics. For this purpose, 560 walnut genotypes in southwest of Iran were evaluated based on UPOV and International Plant Genetic Resources Institute (IPGRI) descriptor. After a 2-year primary evaluation, 25 superior genotypes were selected for future phenotypic and genome size assessment. Flow cytometry was used to estimate genome size of the selected superior genotypes. A high genetic diversity was found in walnut population collected from the southwest of Iran. The selected superior genotypes had high yield, lateral bearing, thin-shell thickness (0.90–1.64 mm), high nut (12.54–19.80 g) and kernel (7.02–9.91 g) weight with light (L) to extra light (EL) kernel color which easily can be removed from the shell. Also, FaBaCh2 genotype turned out to be protogynous being important as a pollinizer cultivar. In addition to extensive phenotypic analysis, genome size was determined. The studied genotypes were diploid (2n = 2x = 32) and varied in genome size from 1.29 (FaBaAv2) to 1.40 pg (FaBaNs12). Correlation analysis showed that lateral bearing, budbreak date, nut size, and weight were the main variables contributing to walnut production. A linear relationship was found between genome size and nut weight (r = 0.527**), kernel weight (r = 0.551**), and nut size index (NSI) (r = 0.487**). Therefore, genome size can be considered as a strong and valuable tool to predict nut and kernel weight and nut size.

High Yield Potential

In Chile, durum wheat is cultivated in high-yielding Mediterranean environments, therefore breeding programs have selected cultivars with high yield potential in addition to grain quality. The genetic progress in grain yield (GY) between 1964 and 2010 was 72.8 kg ha−1 per year. GY showed a positive and significant correlation with days to heading, kernels per unit ground area and thousand kernel weight. The gluten and protein content tended to decrease with the year of cultivar release. The correlation between the δ13C of kernels and GY was negative and significant (−0.62, p < 0.05, for all cultivars; and −0.97, p < 0.001, excluding the two oldest cultivars). The yield progress (genetic plus agronomic improvements) of a set of 40–46 advanced lines evaluated between 2006 and 2015 was 569 kg ha−1 per year. Unlike other Mediterranean agro-environments, a longer growing cycle together with taller plants seems to be related to the increase in the GY of Chilean durum wheat during recent decades.

Abstract Background Ecological environments shape plant architecture and alter the growing season, which provides the basis for wheat genetic improvement. Therefore, understanding the genetic basis of grain yield and yield-related traits in specific ecological environments is important. Results A structured panel of 96 elite wheat cultivars grown in the High-yield zone of Henan province in China was genotyped using an Illumina iSelect 90 K SNP assay. Selection pressure derived from ecological environments of mountain front and plain region provided the initial impetus for population divergence. This determined the dominant traits in two subpopulations (spike number and spike percentage were dominance in subpopulation 2:1; thousand-kernel weight, grain filling rate (GFR), maturity date (MD), and fertility period (FP) were dominance in subpopulation 2:2), which was also consistent with their inheritance from the donor parents. Genome wide association studies identified 107 significant SNPs for 12 yield-related traits and 10 regions were pleiotropic to multiple traits. Especially, GY was co-located with MD/FP, GFR and HD at QTL-ple5A, QTL-ple7A.1 and QTL-ple7B.1 region. Further selective sweep analysis revealled that regions under selection were around QTLs for these traits. Especially, grain yield (GY) is positively correlated with MD/FP and they were co-located at the VRN-1A locus. Besides, a selective sweep signal was detected at VRN-1B locus which was only significance to MD/FP. Conclusions The results indicated that extensive differential in allele frequency driven by ecological selection has shaped plant architecture and growing season during yield improvement. The QTLs for yield and yield components detected in this study probably be selectively applied in molecular breeding.

Allelopathy is a common biological miracle by which one organism produces biochemicals that affect the growth, existence, development, and reproduction of other organisms. These biochemicals are known as allelochemicals and have advantageous, as well as, harmful effects on target organisms. Lichens produce over a thousand different extracellular biochemical terms as secondary metabolites. The lichen secondary metabolites may show either positive effects, such as, in weed control, crop protection, or crop re-establishment or negative effects, e.g., autotoxicity, biological invasion, competition, deterioration, and eutrophic soil sickness. However, several lichen secondary metabolites can potentially be used as growth regulators, insecticidal, and antimicrobial since dated back. Here, we discuss the application of lichen allelopathy in various agricultural prospects in the near future.

Purpose of the study is to assess the efficiency use of oxytocin and titanium aquacomplex glycerosol-vate in the treatment of soft tissue wounds. The study was carried out on 72 white mongrel male rats weighing 210 ± 10 g with simulated aseptic wounds. The sampling was carried out for 1, 3, 5 and 7 days from the beginning of the experiment. To assess the course of wound process in the clinical study, planimetric and histological methods were applied. The comparison of obtained results has allowed to reveal the high efficacy of combined use of oxytocin and glycerosolvate titanium. On the basis of clinical and planimetric methods of investigation it was established that reduction of the area of the wound is significantly faster in animals treated with the use of oxytocin and glycerosolvate titanium. This treatment has a stimulating effect on the activity of connective tissue - accelerates the appearance and maturation of granulation tissue, occur earlier replacement of a number of inflammatory cells into cells, which provide proliferation; earlier appearance of collagen fibers and the prevalence among them horizontally. The use of oxytocin and titanium aquacomplex glycerosolvate in laboratory animals with aseptic wounds influences positively on the dynamic of wounded process, allows to accelerate the appearance of granulation tissue and epithelialization.
