Objective. To study the effect of mycorrhizal preparation "Rizomax" on the basis of an endomycorrhizal fungus Glomus sp. on the growth and development of the root system of the grape plant.Methods. The studies were conducted from 2016 to 2018. The influence and aftereffect of mycorrhizal drug on the root system and growth of the grape bush were studied in the Eastern viticultural district of the South Coast zone of the Crimea. The studies were carried out according to the generally accepted methods used in viticulture.Results. The advantage of introducing mycorrhizal preparation when planting in the zone of the root system is established, in this regard, more intensive growth and root formation occurs, as well as the growth and development of the grape bush improves. The influence of the aftereffect of the studied preparation on grape plants is estimated, it is established that in experimental variants the development of plants occurs more intensively. Due to symbiosis, the grape plant more effectively uses moisture and nutrients accumulated in the mycelium, which is reflected in the improvement of phytometric indicators and high aging of the vine.Conclusions. When conducting studies in 2017-2018, to study the aftereffect of the mycorrhizal preparaion "Rizomax", in the experimental version, a stable excess of growth processes by 38.3% 43.8% and the leaf surface of the bush by 34.5% 41.7% over the control version was established. The ratio of different fractions of roots in the experimental version compared to the control is more favorable. The fouling part of the root system is 2.53 m according to the measurements of the roots, you can see how much soil the roots of the grape bush covered, that is, in the experimental version, the absorption capacity is higher. Well-developed root system and leaf surface provide further, high productivity of grape bushes. Therefore, for good plant nutrition, it is important to maintain a correlation between the root system and the leaf surface.

Lateral Root Development

Abstract Lateral roots are important to forage for nutrients due to their ability to increase the uptake area of a root system. Hence, it comes as no surprise that lateral root formation is affected by nutrients or nutrient starvation, and as such contributes to the root system plasticity. Understanding the molecular mechanisms regulating root adaptation dynamics towards nutrient availability is useful to optimize plant nutrient use efficiency. There is at present a profound, though still evolving, knowledge on lateral root pathways. Here, we aimed to review the intersection with nutrient signaling pathways to give an update on the regulation of lateral root development by nutrients, with a particular focus on nitrogen. Remarkably, it is for most nutrients not clear how lateral root formation is controlled. Only for nitrogen, one of the most dominant nutrients in the control of lateral root formation, the crosstalk with multiple key signals determining lateral root development is clearly shown. In this update, we first present a general overview of the current knowledge of how nutrients affect lateral root formation, followed by a deeper discussion on how nitrogen signaling pathways act on different lateral root-mediating mechanisms for which multiple recent studies yield insights.

The objective of this work was to evaluate root and nodule soybean lipoxygenases in Doko cultivar and in a near isogenic line lacking seed lipoxygenases, inoculated and uninoculated with Bradyrhizobium elkanii. The lipoxygenase activities from roots collected at 3, 5, 9, 13, 18 and 28 days post-inoculation and from nodules collected at 13, 18 and 28 days post-inoculation were measured. The pH-activity profiles from root and nodules suggested that the lipoxygenases pool expressed in these organs from Doko cultivar and triple-null near isogenic lines are similar. The root lipoxygenase activity of Doko and triple-null lines, inoculated and uninoculated, reduced over time. The highest lipoxygenase activity observed at the beginning of root formation suggests the involvement of this enzyme in growth and development of this organ. However, for nodules an expressive increase of lipoxygenase activity was noticed 28 days post-inoculation. Root and nodule showed, at least, two mobility groups for lipoxygenases in immunoblottings, with approximately 94 and 97 kDa.

This article presents data on the rooting of green cuttings of the studied species of ornamental trees and shrubs in a greenhouse with a misting system. We accounted the number of days from planting to the root formation and the number of rooted cuttings for each replication during our performance. We studied the influence of root formation stimulants on the rooting rate of various types of ornamental deciduous, flowering and coniferous plants. The effect of application of root formation stimulants is confirmed by the formation of a high-quality root system that is superior in length to those that were vegetated without “Kornevin”. However, the use of root formation stimulants is not advisable on shrubby cinquefoil, common privet and common lilac “Mademoiselle Casimir Perier”, because there is practically no increase in the rooting rate of cuttings in these plant species, compared to the control plants.

  A study was made of the stimulating effect of benzolinone (3-benzyloxycarbonyl-methyl)-2-benzothiazolinone in powder form (P) and its mixture with indole butyric acid (IBA), the biofungicide Supresivit and fungicide Captan 50 WP on the root formation of 17 species of ornamental plants, park and fruit woody species. Under the action of benzolinone, the yield of rooted cuttings in the category of ornamental plants amounted to 44.5% (in the Dianthus sp.) up to 83.7% (in Rosa canina), in the category of park woody species it was from l6.7 (in Magnolia stellata) to 100% (in Forsythia intermedia). In fruit trees represented by two species, viz. Actinidia arguta and cherry rootstocks, the yield was between 20 and 86.7%, and in two allochthonous species Cotoneaster horizontalis and Philadelphus coronarius it was from 96.7 to 100% in rooted cuttings. In the case of herbaceous and semi-lignified cuttings, lower concentrations of benzolinone below 0.1% were more effective, while on the contrary, higher concentrations of 0.1–0.2% proved more effective with lignified cuttings. In the species with difficult root formation, such as Magnolia stellata, Viburnum farreri and Actinidia arguta, benzolinone demonstrably stimulated both the rhizogenesis, and thereby the overall yield of rooted cuttings, and the quality of the root system. In the case of the species with naturally high rooting ability, the positive effect of benzolinone was manifest mainly in the quality of the root system. The synergistic action of the above stimulants on root formation was achieved in two and three-component benzolinone mixtures with IBA and fungicides on the basis of the active ingredients captan and Trichoderma harzianum. The most evident stimulating effects on the rooting of cuttings in Dianthus sp., Ficus schlechteri and the deciduous species Acer saccharinum Pyramidale, Prunus padus Colorata and Prunus kurilensis Brilliant was obtained in three-component mixtures.

AbstractPopulation change in Myzus persicae (Sulz.) overwintering on spring cabbage in south-eastern England was studied in relation to meteorological and biological factors. Leaf surface wetness and temperature were correlated significantly with rate of population change, but rainfall and wind were not. Growth and development continued slowly throughout the winter, and the relationship with temperature is shown. Hymenopterous parasites, the fungus Entomophthora and predatory spiders did not affect winter survival.

The aim of the study was to evaluate the ef-fect of salicylic acid on the processes of re-generation and root formation in vine grafts during the stratification period. The efficiency of treatment of copulation sections on root-stock cuttings of vines with Salicylic acid (SC) solution was studied) (10-2, 10-4, 10-6, 10-8) during the production of grafted grapevine seedlings. For setting up the experiment, we used the grafted grapevine variety Cabernet Sauvignon, the rootstock - Kober 5BB. In some variants of the experiment, a reduction in the period of vaccination stratification was noted, due to the activation of the process of wound tissue formation. At the same time, the use of salicylic acid stimulated the budding of the scion, the growth of shoots and the devel-opment of the root system. With an increase in the concentration of the solution to 10-2, a slowdown in the growth of shoots was noted. The present results indicate that salicylic acid, being an endogenous stimulator of growth processes, can be used in nursery production.

The article gives brief statistics of state poultry industry in Ukraine, its importance in the market of the country and problematics. The most common pathologies of non-contagious etiology in poultry associated with impaired metabolism are examined in the article. The data on age features of metabolism, level of metabolic processes and critical physiological and technological periods in laying hen sis shown. The greatest load takes over the liver, which is directly or indirectly involved in all metabolic and functional changes of hepatocytes cause a breach in the systems of organs and in organism as a whole. The analysis of scientific literature and numerous studies in recent years shows that the disease of the liver (hepatosis or dystrophy of hepatocytes, hepatitis and cirrhosis) are very common among poultry and are composed from 5.0 to 50.8% of all non-communicable diseases. A feature of these diseases is hidden (subclinical) course, which complicates their timely diagnosis and effective prevention. One direction solution to the problem is to normalize metabolic processes in the body and morpho-functional state of the liver is to use hepatoprotectors. It is established that the group of these medications in recent years, acquired widespread adoption due to the intensive rearing of poultry and for protection their organism against unfavorable external and internal environment. Hepatoprotectors, improving metabolism in the liver, provide intensive growth, development and high productivity of poultry. The selection studies of physiological period of laying hens for using hepatoprotectors in the prevention of liver diseases is required, in particular hepatosis for conducting clinical examination of how the system measures to prevent metabolic diseases of poultry. It is necessary to improve methods of early diagnosis the dysfunction of the liver and use effective methods of correction of metabolic processes.
