Abstract The objectives of this study were to determine the efficacy, range of activity and effective concentrations (EC50 and EC80) of abamectin as a seed treatment of tomato against Meloidogyne incognita, M. arenaria and M. javanica. The study revealed that abamectin seed treatment at concentrations ranging between 0.3 and 1 mg a.s. seed−1 is highly effective against the three species of root-knot nematodes, retaining its efficacy in the soil for 8 weeks. The highest EC50 found was reached at 0.2 mg a.s. seed−1. The highest EC80 for the number of egg masses per g root in the three Meloidogyne species was attained at 0.51 mg a.s. seed−1. Abamectin as a seed treatment is promising for the control of root-knot nematodes in the field since only low amounts of active ingredient are required to give adequate protection in the most sensitive stages of tomato root growth and development.

The article is devoted to the study of the effect of foliar treatment of Tomatillo plants with the use of drugs of bacterial origin. The paper scientifically substantiates the influence of biologicals on the morphological and biometric parameters of the plant. It was investigated that the emergence of seedlings in varieties Lichtaryk and Pineapple was observed for 7-8 days. After diving and two treatments of plants with drugs, their positive effect on the growth and development of Tomatillo, especially in the phase of budding, flowering and fruiting. A short period of bud formation on the plant was characterized by a variety of Tomatillo Lantern from the use of Biomag. Thus, the beginning of the formation of buds occurred on 66 days on the Lantern variety. A similar effect of the biological product was found during the flowering phase and fruit set. As a result of the activity of Azotobacter chorococum bacteria, the growth and development phases of the Lantern variety are accelerated by 1-3 days compared to the control variant. The use of biological products has had a positive effect on the biometric parameters of the plant. When using bacteria p. Saccharomyces, Azotobacter chroococcum, Paenibacillus polymyxa, Enterobacter nimipressuralis, plant height and stem diameter depended on the type of biological product used. The height of the plant ranged from 82,8 cm to 89,6 cm in the variety Lantern and from 86,8 cm to 91,3 cm in the variety Pineapple. As a result of spraying the plants with Azotobacterin or Rostmoment, the height of the Tomatillo plant exceeded the height of the plant of the variant where biological products were not used. In these variants, the excess of plant height relative to the control was 8,2% for the variety Lantern and 4,3 % for the variety Pineapple, respectively. The diameter of the stem was in the range of 1,9-2,0 cm. Due to the activity of the bacteria Azotobacter chroococcum, Paenibacillus polymyxa, Enterobacter nimipressuralis or yeast p. Saccharomyces and products of their metabolism, revealed a positive effect of biologicals on the increase in leaf area and dry matter content of the leaf. As a result of cultivation of the cultivar Lichtarik and application of Rostmoment or Biopolitsid the area of leaves was at the level of 79,5 thousand м2/ha and 77,6 thousand м2/ha. Growth moment, for the cultivation of the variety Lantern, helped to increase the dry matter content of the leaf by 16,4 %. Treatment of Lantern plants with liquid humus-based concentrate Humisol provided the highest weight of Tomatillo fruit, which was at the level of 8,4 g, and the use of Humisol or Rostmoment for growing varieties Lantern and Pineapple increases the diameter of Tomatillo fruit by 6,9-10,3 %. Humisol, due to humic and fulvic acids, natural phytohormones affects the growth processes of the plant more intensively, which provided in the formation of the largest mass of fruits and their diameter. High yield is characterized by the Tomatillo variety Lantern with five applications of Humisol or Biopolicide, where its value is 33,3 t/ha and 32,0 t/ha. Key words: morphological features, biometric indicators, tomatillo, fruit yield, marketability.

The soybean (Glycine max) is one of the most important food plants of the world, and seems to be growing in importance. It is an annual crop, fairly easy to grow, that produces more protein and oil per unit of land than almost any other crop. It is a versatile food plant that, used in its various forms, is capable of supplying most nutrients. It can substitute for meat and to some extent for milk. It is a crop capable of reducing protein malnutrition. In addition, soybeans are a source of high value animal feed. Nevertheless, the soybean is adapted primarily to the Temperate Zone. Each improved variety has an adaptation determined in large part by latitude. Soybean requires careful home processing to bring out its best qualities, and if not well prepared, it has an off-flavor that is seldom appreciated Soybeans need to be inoculated with a particular strain of Rhizobium fungus before planting. This fungus fixes nitrogen (i. e. takes elemental nitrogen from the air and adds it to the soil in a form that the soybean plant can use). However, if soybeans are planted in a field that contained soybeans as a previous crop, they may not require inoculation because the Rhizobium will still be in the soil. If soybeans are not grown in association with Rhizobium, they will grow more slowly, require nitrogen fertilizer, and yield less. Rhizobium inoculum must be fresh (viable) and is usually purchased with the seed. If Rhizobium inoculum is not available in a particular area, and soybeans are not now being grown, it may be difficult to produce this crop. Soybeans need fertilizer, including both the macronutrients phosphorous and potassium (P and K) and sometimes micronutrients. Nitrogen is not required if soybeans are properly inoculated. Soybeans need rather large amounts of phosphorous, calcium, magnesium, and sulfur. Minor elements are sometimes required. Soybeans cannot be recommended for unfertilized soils. For optimum soybean yield, it is necessary to use both biological N2-fixation and nitrogen uptake by soybean roots. Nitrogen fertilizer applied to soybean is based on the plant nitrogen needs during seedling development prior to nodule formation that is crucial to the growth and development of soybean As with all crops, soybean yield is the result of the net accumulation of organic compounds assimilated through photosynthesis. Research on soybean photosynthesis conducted during the 1950’s and 1960’s found that several cultivars grown at that time became light saturated. However, much of those data were collected from plants grown in a greenhouse or other artificial environment. Much of the information on the response of soybean photosynthesis to changing light levels however is dated, having been published prior to 1985, with cultivars that are no longer in production, using less portable and sophisticated instrumentation than is now available. In the article are presented results of researching peculiarities of growth development and formation of soybean photosynthetic productivity depending on weather conditions, level of mineral fertilization and different application methods of biological product on the chelate form under conditions of the Right-bank Forest-Steppe. It is established that a systematic approach to soybean nutrition, namely its cultivation on the background of optimal doses of mineral fertilizers N30P45K45 and the use of biological product Organic-Balance for seed treatment in combination with foliar feeding creates the best conditions for growth, development and preservation of maximum plants full ripeness, which is the basis for obtaining high grain yields.

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.
