Field Germination

A characteristic property of legumes is the formation of hard-stone seeds. To use such seeds for sowing, it is necessary to carry out measures to increase their seeding indicators. The article provides an overview of methods of pre-sowing preparation of seeds, priming (Seed Priming). The harvest of Birdsfoot trefoil (Lotus corniculatus L.) can contain up to 90% or more hard-stone seeds. Mechanical priming of hard-stone seeds of Birdsfoot trefoil increases their germination energy and field germination.

A study was conducted to determine the response of five pea varieties (Pisum sativumL.) to damage degree ofBruchus pisorum: Glyans, Modus, Kamerton, and Svit (Ukrainian cultivars) and Pleven 4 (Bulgarian cultivar). The seeds were classified into three types: healthy seeds (type 1), damaged seeds with parasitoid emergence hole (type 2), and damaged seeds with bruchid emergence hole (type 3) and they were sown. It was found that the weight of 1000 seeds did not affect the field germination of the pea varieties. Healthy and damaged seeds with parasitoid emergence holes (first and second seed types) provide a very good opportunity for growth and development while plants from damaged seeds with bruchid emergence holes had poor germination and vigor and low productivity. These seeds cannot provide the creation of well-garnished seeding and stable crop yields. Among tested varieties, the Ukrainian variety Glyans had considerably higher seed weight, field germination, and index germination and weak egg-laying activity ofB. pisorumcompared to others. Use of spring pea cultivars that are weakly preferred by the pea weevil in breeding programs would reduce losses due to pea weevil and provide an environmentally safer option to its control.

The article examines the indicators of the structure of yields of spring wheat plants, depending on the variety in the conditions of the Chuvash Republic. The density of shoots is the first indicator of the structure of yield, which can be assessed visually. On its basis, it is possible to conduct a survey of crops, paying attention to the uniformity and amicability of emergence. According to the data (Makarova VM, 1995), in the conditions of the Non-Chernozem Zone, the optimum density of seedlings of grain crops should be considered no less than 400-500 plants per 1 m2 at the rate of sowing 6 million virgin grains per 1 hectare, while ensuring the field germination level 70 - 80%. It is known that not all seeded seeds are seedlings. Therefore, distinguish between laboratory and field germination. It should be noted that there is still a concept of the completeness of seedlings, which many people still understand as synonymous with field germination. During the vegetation the number of plants per unit area does not remain unchanged. Due to a number of reasons, attacks are observed in the crop, (Terekhov M.B., 2000). The survival rate of plants is the percentage of plants that have survived to harvest, or the ratio of the total or productive number of plants before harvesting to the number of shoots per m2.

The paper describes a method for creating new and increasing the yield of existing varieties based on analysis variability elements of rice varieties yield structure under influence of environmental conditions. Seeding rates are used as a source of variability. Following trait are analyzed: seeds field germination, survival plants before harvesting, total tillering of plants, realization of total tillering, graininess of panicle, fertility of spikelets, weight of 1000 grains. Based on analysis, through onnections conjugated elements, the optimal values of elements structure of yield are determined, at which it takes the maximum value. Based on a set of optimal values, theoretical model of studied rice variety is being developed. Then, according to panicles selected in variety, single-row plots are sown for further propagation, rows with parameters of the yield structure elements set same with model of variety are selected, which makes it possible to increase the yield of Mavr rice variety by 39.18 centners / ha or 45.61%.

Soft Winter Wheat

The yield potential of winter wheat (Triticum aestivum L.) is formed in changing weather conditions and depends on the proposed agro-technological measures, to which the response of a particular variety is different. The purpose of this study was to determine the influence of weather factors on the field germination of soft winter wheat seeds, the growth and development of plants in the autumn and wintering in the zone of the Western Forest-Steppe of Ukraine, by sowing high-quality basic seed, careful soil preparation and the presence of optimum environmental factors. A sufficient level of productive soil moisture, which protects young shoots from possible deficiency after germination and is a long-term source of moisture at the next stages of organogenesis, has a great influence on obtaining friendly and timely shoots. Often overwintering conditions, when plants suffer from low negative temperatures at the beginning and at the end of the winter period, ground ice crust, resumption of vegetation in winter are the causes of freezing, loss, and ultimately a decrease in yield and seed quality. It has been confirmed that an increase in the temperature regime in 244-247°C in the autumn-winter period and the optimal amount of precipitation contribute to sufficient (31.6-34.6 mm) productive soil moisture (0-20 cm), which positively influences the process of germination of soft winter wheat, provides a high percentage of field germination of seeds of varieties (93.8-94.5%), lengthens the autumn development of plants by 3-12 days, which causes 3.5-5.7% higher accumulation of sugar content in the tillering nodes and a high percentage of overwintering (up to 95.5-96.4%). Varieties of the forest-steppe ecological type of soft winter wheat have insignificant phenotypic variability of adaptive traits, therefore, in the production of grain and seed products, it is recommended to give preference to the plant varieties listed in the Register, suitable for distribution in Ukraine for the Forest-Steppe zone, Polissya. The recommendations set out in this scientific work will help agricultural producers of the studied soil and climatic zone to carry out an effective, more ecologically plastic, highly productive variety replacement

Halogeton Glomeratus

The longevity of brown and black forms of seed of halogeton (Halogeton glomeratus (M. Bieb.) C. A. Mey.), buried at four depths, was determined for a 10-year period in Nevada, Idaho, Utah, and Washington. The black form of seed had almost 100% field germination at all depths by the end of the first year and had completely germinated or was nonviable by the end of the second. Brown seed on the soil surface began field germination the first year at all locations and had germinated or become nonviable at the end of 6 years. Burial at 1, 3, and 6 inches delayed the peak of viability and tended to increase longevity of brown seed. Germination was less than 0.5% at the end of 10 years, and viability was near zero under both field and laboratory conditions. Seed germinated and lost viability most rapidly in Washington, the location where most favorable winter conditions for germination occurred.
