Лещук, Н. В
Purpose. Providing a scientific rationale for the practical application of analysis of variance elements to determine the range of morphological and value for cultivation and use (VCU) characteristics of Romaine lettuce ‘Skarb’ variety. Results. The Romaine lettuce ‘Skarb’ variety was identified by the type of display of quantitative (QN) identification characteristics. VCU characteristics of the var. longifolia L. varieties were determined and statistically processed. The author focused on practical application of histogram and variation curve of phenotype morphological characteristics when performing the uniformity test. The correlation between quantitative characteristics of lettuce leaf and head was observed when plant productivity was developing. Romaine lettuce yield value was verified statistically. Thresholds were established for the indices under study, confidence intervals were defined over the years of study. Conclusions. The use of Lewis stability factor (S.F. = Xmax/Xmin) allowed to establish the stability of each characteristic display. Practical application of the histogram and variation curve for determining code of display of quantitative morphological characters and the range of VCU characteristics of the Romaine lettuce ‘Skarb’ variety was scientifically grounded.

Духницький, Б. В | Сіліфонов, Т. В
Purpose. To analyze peculiarities of Ukrainian cereals and oilseeds trade, the situation on the world market, and determine future prospects of its development. Methods. Analysis and synthesis, comparative evaluation, graphic procedure. Results. The role and place of Ukraine in a total grain supply to the world market was determined. Ukraine is a world’s top ten grain producer. Among domestic agricultural products, cereals, oilseeds and sunflower oil are in the highest demand in the world. In recent years, our state has reinforced its status as one of the leading exporters of cereals. The commodity pattern of cereals and oilseeds export was analyzed with specifying most in-demand positions and the main countries purchasing these products. According to the results of 2015, Ukraine obtained the highest foreign currency revenue from export of corn, wheat and barley (in grain structure) including soybeans and rapeseed (among oil crops). Key domestic and multinational operators are the main exporters of cereals and oilseeds in Ukraine and still hold their leading position. It was found a significant excess of import price of seeds as compared with export price of crops grown in Ukraine. Assortment of maize and sunflower seeds offered by major companies-producers in Ukraine was studied. Main trends of the world grain market development are considered. Conclusions. It was established that Ukraine is one of the major exporters of cereals and oilseeds. However, volatility of their prices significantly affects the export revenue that was decreasing even with increasing export quantities in kind. The dependence of domestic grain industry development on high-quality imported seed of maize and sunflower hybrids was recorded. It is expected that in the years to come Ukraine will maintain its strong positions in the world’s grain market.

Purpose. Developing technology for clonal micropropagation of peppermint (Mentha piperita L.) plants of Ukrainian breeding based on the complex of methods of isolated tissue and organ culture in vitro. Methods. During the experiment, such methods as isolated tissue and organ culture in vitro, clonal micropropagation, detached scion grafting, chemotherapy with adding of virucide Ribavirin to the nutrient medium, biometric and statistical ones were used. Results. The stepped procedure of sterilization that we have developed allows to receive 88–100% of sterile explants. For M. piperita L. introduction into culture and clonal micropropagation, Murashige and Skoog (MS) nutrient medium appeared to be optimal supplemented with 6-benzylaminopurine (0.75 mg/l), adenine (0.05 mg/l), indole-3-acetic acid (IAA) (0.05 mg/l) and gibberellic acid (0.5 mg/l) on which the reproduction ratio on the 28th day ranged between 1:7 and 1:15. For recovery of plants from viral infection, virucide Ribavirin at concentration of 10 mg/l was added to the nutrient medium. The proposed nutrient medium for rhizogenesis, that contained IAA (0.5 mg/l) and indole butyric acid (IBA) (0.5 mg/l), allows to obtain the frequency of rhizogenesis up to 84–100%. Regenerated plants were adapted to the conditions in vivo on substrate peat : universal soil : perlite : sand in the ratio 2:1:1:1. The survival rate for peppermint varieties amounted to 96–100%. Conclusions. Biotechnological scheme was developed that permits to get healthy, purebred planting material and intensively propagate plants for supplying breeding programs of the Experimental Station for Medicinal Plants of the Institute of Agroecology and Environmental Management of the National Academy of Agrarian Sciences of Ukraine, among which such varieties as ‘Lebedyna pisnia’ and ‘Ukrainska pertseva’ were selected as the most promising for clonal micropropagation.

Purpose. Determination of sowing time effect on productivity of various fenugreek species in the Forest-Steppe zone of Ukraine. Methods. Field study, laboratory test, analytical approach and statistical evaluation. Results. Effect of sowing time on economic characters of common fenugreek (Trigonella foenum graecum L.) and blue fenugreek (Trigonella coerulea (Desr.) Ser.) was investigated. It was found that sowing time significantly influenced the individual productivity of plants and average yield of their fresh and dry matter. In particular, common and blue fenugreek plants formed not only the most developed vegetation but also higher productivity and fresh and dry matter yield, respectively, due to early-spring sowing. In case of summer sowing, the poorest yield of dry matter per unit was obtained for these species caused by a low fresh yield, though the moisture loss index was lower. Conclusions. Common fenugreek is promising for producing “mushroom grass” spices, and the conveyor supply of production in the Forest-Steep zone of Ukraine can be ensured by the first sowing time (the first or the second decades of April) and the second sowing time (the third decade of April) as during this period more developed vegetation is formed that favored the higher yield of dry matter (1,3–1,5 t/ha).

Определить влияние сроков сева на продуктивность разных видов пажитника в условиях Лесостепи Украины. Методы. Полевой, лабораторный, аналитический и статистический. Результаты. Исследовано влияние сроков сева на хозяйственно-ценные признаки пажитника сенного (Trigonella foenum graecum L.) и пажитника голубого (Trigonella coerulea (Desr.) Ser.). Установлено, что на индивидуальную продуктивность растений и среднюю урожайность их зеленой и сухой массы существенно влиял срок сева. В частности, более развитую вегетативную массу и продуктивность и, как следствие, большую урожайность зеленой и сухой массы имели растения пажитника голубого и сенного при ранневесенних сроках сева. Самый маленький выход сухой массы этих видов с единицы площади получено при летних сроках сева из-за небольшой урожайности зеленой массы, несмотря на более низкий показатель потери влажности. Выводы. Для получения пряности «грибная трава» перспективным является использование пажитника сенного, а для конвейерного поступления продукции в Лесостепи Украины – применение 1-го (I–II декады апреля) и 2-го (III декада апреля) сроков сева, при которых формируется более развитая вегетативная масса и установлена большая урожайность сухой массы (1,3–1,4 т/га). | Мета.

Встановлено, що на індивідуальну продуктивність рослин та середню врожайність їх зеленої та сухої маси істотно впливав строк сівби. Зокрема, розвиненішу вегетативну масу й продуктивність та, як наслідок, вищу врожайність зеленої та сухої маси мали рослини гуньби голубої та сінної за ранньовесняних строків сівби. Найменший вихід сухої маси цих видів з одиниці площі отримано за літніх строків сівби через невелику врожайність зеленої маси, незважаючи на нижчий показник втрати вологості. Висновки. Для отримання прянощів «грибна трава» перспективним є використання гуньби сінної, а для конвеєрного надходження продукції в Лісостепу України – застосування 1-го (I–II декади квітня) та 2-го (III декада квітня) строків сівби, за яких формується розвиненіша вегетативна маса та встановлено вищу врожайність сухої маси (1,3–1,4 т/га).

Purpose. Comparative studies of the photosynthetic apparatus of winter wheat varieties of modern and earlier breeding in the relation to their productivity. Methods. Field, pot experiment, biometrical, gas analysis, analytical and statistical ones. Results. It is found that the modern high-yielding winter wheat varieties have a higher rate of flag leaf photosynthesis during generative period of development, particularly at grain filling period, improved ability to store assimilates in stem and effectively use them later for grain growth. The modern varieties form crop canopy with greater leaf area and chlorophyll indexes and larger photosynthetic capacity and maintain functional activity of photosynthetic apparatus longer at the end of the growing season. Conclusions. The superiority for grain productivity of modern high-yielding wheat varieties, originated from the Institute of Plant Physiology and Genetics, NAS of Ukraine, over varieties released before the “green revolution”, results from increased capacity and durability of functioning the crop photosynthetic apparatus, higher CO2 assimilation rate and optimization of source-sink relations in whole plant.

Установлено, что новые высокоинтенсивные сорта озимой пшеницы имеют более высокую интенсивность фотосинтеза флагового листа в течение генеративного периода развития, особенно во время налива зерна, улучшенную способность запасать ассимиляты в стебле и эффективно использовать их в дальнейшем для налива колоса. Новые сорта формируют посевы с большими значениями хлорофильного индекса и хлорофильного фотосинтетического потенциала и более длительным сохранением функциональной активности фотосинтетического аппарата в конце вегетации. Выводы. Преимущество по зерновой продуктивностью новейших высокоинтенсивных сортов пшеницы, оригинатором которых является Институт физиологии растений и генетики НАН Украины, перед сортами, созданными до начала «зеленой революции», обеспечивается повышением мощности и продолжительности функционирования фотосинтетического аппарата посева, более высокой интенсивностью фотосинтеза и оптимизацией донорно-акцепторных отношений в системе целого растения. | Мета. Порівняльний аналіз показників фотосинтетичного апарату сортів озимої пшениці сучасної і більш ранньої селекції у зв’язку з їх продуктивністю. Методи. Польовий, вегетаційний, фітометричний, газометричний, аналітичний, статистичний. Результати. Встановлено, що нові високоінтенсивні сорти озимої пшениці мають вищу інтенсивність фотосинтезу прапорцевого листка протягом генеративного періоду розвитку, особливо під час наливу зерна, поліпшену здатність запасати асиміляти в стеблі та ефективно використовувати їх в подальшому для наливання колоса. Нові сорти формують посіви з більшими значеннями хлорофільного індексу й хлорофільного фотосинтетичного потенціалу та тривалішим збереженням функціональної активності фотосинтетичного апарату в кінці вегетації. Висновки. Перевага за зерновою продуктивністю новітніх високоінтенсивних сортів пшениці, оригінатором яких є Інститут фізіології рослин і генетики НАН України, порівняно з сортами, створеними до початку «зеленої революції», забезпечується підвищенням потужності й тривалості функціонування фотосинтетичного апарату посіву, вищою інтенсивністю фотосинтезу та оптимізацією донорно-акцепторних відносин у системі цілої рослини.

Purpose. Determination of the possibility to differentiate triticale samples by starch grain size and identify samples with a minimum size of granules that have a significant positive correlation with the efficiency of the starch transformation into ethanol. Methods. Light microscopy of grinded triticale grains. Results. Analysis of the starch granule size in triticale samples was performed. The minimum average granule size was observed in line Kc-270/14 (23.78 µm), maximum one – in line KR-110/14 (28.06 µm). The size of starch granules in a soft winter wheat variety ‘Tsvit Kalyny’ was 24.2 µm that was within the values typical for winter triticale varieties and lines. The size of the majority of granules ranged from 15 to 35 µm, but their distribution was uneven in the studied lines. Conclusions. Considerable polymorphism of winter triticale for the starch granule size was established. It was found that the minimum average size of starch granules was observed in the samples characterized by minimum maximum size of granules, low frequency of granules of more than 35 µm, and therefore, minimum dispersion. Based on this, assumption can be made about the possibility to evaluate a sample for the presence of granules larger than 35 µm that can significantly reduce the number of measurements and speed up analysis.

Определить возможность дифференциации образцов тритикале по размеру крахмальных зёрен и выявления образцов с минимальным размером гранул, что имеет значительную позитивную корреляцию с эффективностью трансформации крахмала в этанол. Методы. Световая микроскопия размолотых зерен тритикале. Результаты. Проведен анализ образцов тритикале по размеру гранул крахмала. Средний размер гранул был минимальным у линии Кс-270/14 (23,78 мкм), максимальным – у линии Кр-110/14 (28,06 мкм). Размер гранул крахмала у сорта пшеницы озимой мягкой ‘Цвит Калыны’ составлял 24,2 мкм, что было в границах значений, типичных для сортов и линий тритикале озимого. У преобладающего большинства гранул размер варьировал от 15 до 35 мкм, но распределение их по размеру было неравномерным у исследуемых линий. Выводы. Установлен значительный полиморфизм тритикале озимого по размеру гранул крахмала. Выявлено, что наименьший средний размер крахмальных зерен наблюдался у образцов с наименьшим максимальным размером гранул, низкой частотой гранул с размерами более 35 мкм и, соответственно, минимальной дисперсией. На основании этого можно сделать допущение о возможности оценивания образца по наличию гранул размером более 35 мкм, что значительно уменьшит количество измерений и ускорит анализ. | Мета. Визначити можливість диференціації зразків за розміром крохмальних зерен та виявлення зразків з мінімальним розміром гранул, що має значну позитивну кореляцію з ефективністю трансформації крохмалю в етанол. Методи. Світлова мікроскопія розмелених зерен тритикале. Результати. Проведено аналіз зразків тритикале за розміром гранул крохмалю. Середній розмір гранул був мінімальним у лінії Кс 270/14 (23,78 мкм), максимальним – у лінії Кр-110/14 (28,06 мкм). Розмір гранул крохмалю у сорту пшениці озимої м’якої ‘Цвіт Калини’ становив 24,2 мкм, що було в межах значень, типових для сортів та ліній тритикале озимого. У переважної більшості гранул розмір варіював від 15 до 35 мкм, але розподіл їх за розміром був нерівномірним у досліджуваних ліній. Висновки. Встановлено значний поліморфізм тритикале озимого за розміром гранул крохмалю. Виявлено, що найменший середній розмір крохмальних зерен спостерігався у зразків з найменшим максимальним розміром гранул, низькою частотою трапляння гранул з розмірами понад 35 мкм та, відповідно, мінімальною дисперсією. Це дає підставу зробити припущення про можливість оцінювання зразка за наявністю гранул розміром понад 35 мкм, що значно зменшить кількість вимірювань та прискорить аналіз.
