Abstract. This investigation was conducted during 2014, 2015 and 2016 in the field of the citrus experimental station in Ciano, the general corps of scientific agricultural researches. The growth and yield of orange trees (Washington navel 141) budded on seven citrus rootstocks (Sour orange, Troyer citrange, Carrizo citrange, Citrumelo 4475, Citrumelo 1452, Macrophylla and Cleopatra mandarin) and farmed since 1989 have been studied. The results for the average of yield showed that the trees grafted on Cleopatra mandarin (58.33 kg. tree-1) were significantly superior to those grafted on Macrophylla (34.17 kg. tree-1). Orange trees grafted on Citrumelo 4475 and Citrumelo 1452 were significantly superior to other treatments in trunk section area of the rootstock (922.41 and 841.02 cm2, respectively). The greatest fruit fresh weight was in trees grafted on Citrumelo 4475 (284.85 g. fruit-1) which were significantly superior to those grafted on Carrizo and Troyer citrange (232.49 and 236.06 g. fruit-1, respectively). The biggest total soluble solids (%) was in trees grafted on Carrizo and Troyer citrange (12.83% for both treatments) which were significantly superior to those grafted on Sour orangе and Macrophylla (11.5% for both treatments), while the greatest total acids (%) was by Sour orange (2.08%) without significant differences.

Quality of Carrots Grown for Processing as Affected by Nitrogen Fertilization and Harvest TermIn 2007-2008 the effect of nitrogen fertilization and harvest term on quality of two carrot cultivars was investigated. The field experiment was carried out in Żelazna Experimental Station of Warsaw University of Life Sciences. Karotan F1and Trafford F1cultivars, commonly grown for juice industry, were the objects of the experiment. Carrot seeds were sown at the beginning of May. Nitrogen fertilization was applied in five rates, ranged from 0 to 120 kg·ha-1and in two terms — before sowing and in the middle of growing season. Roots were harvested in three terms: mid-September, mid-October and the first decade of November. After harvest there were determined: nitrates (NO3) content in carrot roots and juice, soluble solids, colour parameters of juice in CIE L*a*b*system. The dose and the term of nitrogen fertilization influenced nitrates content in carrots, and the highest NO3concentration was found in carrots fertilized with 120 kg·ha-1of N before sowing. Karotan showed higher nitrates accumulation than Trafford. The content of nitrates in the roots was markedly higher than in carrot juice. Nitrates content in carrots decreased with delaying of harvest time, in opposite to soluble solids content. Soluble solids content and colour parameters of carrot juice were not affected by nitrogen fertilization, but the lowest L*, a*and b*values were observed at the last term of harvest.

Subject. The article analyzes the expected effect of a portfolio of projects in the face of risk and uncertainty, when using real options. Objectives. The purpose is to offer a more objective formula to assess the expected impact of a portfolio of projects for real investment objects under risk and uncertainty, using real options, and provide recommendations for improving the portfolio efficiency. Methods. The study draws on methods of real options and evaluation of investment projects through the real option value, the cash flow discounting method, synthesis, and mathematical modeling. Results. We systematized the main types of real options and developed a formula for calculating the expected effect of project portfolio implementation. The said formula shows that considering the additional long-term costs embedded in a portfolio of real options, which are associated with the use of these real options, and, therefore, reducing the overall risk of projects and the entire portfolio, permit to improve the objectivity of such calculations. Conclusions. When analyzing real options that have real assets as underlying instruments, it is often impossible to apply the computational formulae for financial options, as they differ significantly. The systematization of the main types of real options helps expand the range of application of management solutions. The offered formula enables to improve the efficiency of project insurance under risk and uncertainty and to use additional opportunities for effective development of the company.

Цель исследований: изучение влияния сортового и экологического факторов на изменчивость морфометрических (длина семени, эндосперма и зародыша) параметров семян моркови в системе двухфакторного опыта. Объекты для изучения – оригинальные семена сортов Шантенэ 2461 и Боярыня. Опыты были заложены в 2015–2017 годах на Западно-Сибирской овощной опытной станции ФГБНУ ВНИИО в южной части Первомайского района Алтайского края. Преобладающие почвы – черноземы выщелоченные и обыкновенные. Повторность опыта трехкратная, в каждой повторности не менее 20 семян. Измерение длины семени и эндосперма проводили штангенциркулем (ГОСТ 166-89), длину зародыша определяли с использованием микроскопа Микромед и видеоокуляра DCM 300 MD. Семена замачивали в 14%-ном водном растворе гипохлорита натрия в течение 1 ч, после чего измеряли длину семени, эндосперма и зародыша и рассчитывали соотношение длины зародыша (E) к длине эндосперма (S). Семена двух сортов моркови, за годы исследования существенно различались по длине семян (Р < 0,001). Длина эндосперма сорта Боярыня в среднем за годы исследований была меньше (Р < 0,001) по сравнению с Шантенэ 2461. Длина зародыша также существенно отличалась (Р < 0,001) в зависимости от сорта. Экологический фактор значительно влиял на длину семени (Р=0,005) и эндосперма (Р=0,003). На длину зародыша основное влияние оказывал фактор сорта (Р < 0,001). На отношение длины зародыша к длине эндосперма также в значительной степени влиял фактор сорта (Р = 0,006). Исследования показали, что изменчивость морфометрических параметров семян обусловлена как влиянием сорта, так и влиянием условий года репродукции. Длина зародыша по сравнению с другими элементами семени варьирует сильнее и в большей степени зависит от влияния наследственного фактора. Это позволяет сделать вывод о возможности селекционного изменения линейных, а также относительных размеров морфологических элементов семени.The article is devoted to the study of the effect of varietal and environmental factors on the variability of morphometric (seed length, endosperm and germ) parameters of carrot seeds. The objects for the study were the original seeds of different varieties grown in 2015, 2016 and 2017. Seeds obtained from two varieties of carrots over the years of research differed significantly in the length of the seeds (P <0.001). The length of the endosperm varieties Boyarynya on average over the years of research was less (P <0.001) compared with Shantane 2461. The experiments were conducted in 2015-2017 at the West Siberian Vegetable Experimental Station in the southern part of the Pervomaisky district of the Altai region. The prevailing soils are leached and ordinary chernozems. Experiment replication is 3, each repeatability consists at least 20 seeds. The measurement of the length of the seed and the endosperm was carried out with Vernier caliper (GOST 166-89), the length of the embryo was determined using microscope Mikromed and video-ocular DCM 300 MD. Seeds were soaked in 14% aqueous sodium hypochlorite solution for 1 h, and then measured the length of the seed, the endosperm and the embryo, and calculated the ratio of the length of the embryo (E) to the length of the endosperm (S). Embryo length was also significantly different (P <0.001) depending on the variety. The environmental factor had a significant impact on the length of the seed (P = 0.005) and endosperm (P = 0.003). The length of the embryo was mainly affected by the factor of the variety (P <0.001). The ratio of the embryo length to the endosperm length was largely influenced by the factor of the variety (P = 0.006). Our studies have shown that the variability of the morphometric parameters of seeds is due to both the influence of the variety and the conditions of the year of reproduction. In comparison with other elements of the seed, the embryo length varies more and depends more on the influence of the hereditary factor. This allows us to conclude about the possibility of a selection change in linear as well as relative sizes of the morphological elements of the seed.
