Key nutritional characteristics of the fruit flesh of 41 sour cherries growing in the region of Umbria in central Italy have been determined. Fruit size, flesh dry matter content, nonstructural carbohydrates, organic acids, and anthocyanins were the analyzed parameters. Both the growing environment and genotype were statistically significant for most of the characteristics. Morello sour cherries were characterized by a large amount of sorbitol (up to 44.2 mg·g−1 FW), which contributed significantly to the dry matter content of the flesh, malic acid content that was higher (up to 48.4 mg·g−1 FW) than any published values for cherry flesh, and high anthocyanin content (up to 383.4 mg per 100 g FW). Cyanidin 3-glucosyl rutinoside was the most abundant compound. The analyzed germplasm could be the basis for breeding programs and new industrial products with high nutritional value.

<p style="text-align: justify;">Three-year-old grapevines of four cultivars (Garnacha tinta (Grenache noir), Tempranillo, Chardonnay and Airén) were grown on 35 L container under full irrigation and restricted irrigation conditions in order to determine the effect of water stress on carbohydrate allocation. Total grapevine dry matter was measured at pruning, fruitset, veraison and harvest. Roots, wood, shoots, leaves and clusters were dried separately. Shoots were the most affected organs by water stress, while wood was the least affected. Vines under water stress partitioned more dry matter to wood and roots to the detriment of fruits and shoots. The period from fruitset to veraison was the most active for dry matter accumulation under conditions of stress, whereas non-water stressed vines accumulated more dry matter from veraison to harvest. Under both irrigation treatments, fruits competed with roots for dry matter partitioning. Irrigation treatment and cultivar determined fruit size. Fruit size determined dry matter partitioning between organs and the dry matter accumulation pattern.</p>

Cornelian cherry in Poland belongs to the alternative fruit species. The fruits are suitable for fresh consumption, however they can be used for processing: juice, jams, jellies, syrups, tinctures. Fruits are abundant in mineral elements, vitamin C, organic acids, iridoids, anthocyanins and due to that they have health-promoting significance. In this experiment, the fruit quality of several 16-year-old ecotypes in the Lublin region was compared. They were compared in terms of the beginning of fruit ripening and fruit size (length, diameter, mass), fruit shape index, share of stone in the fruit, SSC, TA, SSC/TA, reducing sugar, dry matter content and anthocyanins content. The color of fruit was evaluated in two dates, visually and using HanterLab spectrophotometer. Cornelian cherry fruits began to mature at the beginning of August and at the latest at the end of August. With the increase of the maturity degree, the SSC, reducing sugars, TA, dry matter and anthocyanins increased significantly. There was no difference in the taste of light red fruits and dark red fruits, which were characterized by similar ratio of SSC/TA. Ecotype No. 11, as the earliest maturing, with big round fruits, dark red colored with the highest content of anthocyanins, could be distinguished. As well as ecotypes No. 4 and 5, ripening in mid-August, and having a high ratio of SSC/TA, providing a good taste. Studied ecotypes could be used in breeding programs to incorporate a wide range of quality and agronomic characteristics into a final cornelian cherry cultivar.

The purpose of this study was to practice and improve the use of low volume crowns in a high-density system in order to obtain qualitative cherry production that would be competitive on the market and to make efficient use of the labor force. The research was carried out in the intensive cherry orchard planted in the autumn of 2011 with “Ferrovia”, “Kordia”, and “Regina” varieties, grafted on Gisela 6 (Prunus cerasus × Prunus canescens) rootstock interspaced at 4x2.5 m and managed according to the Ameliorated natural crown systems with low volume, Ameliorated Slender Spindle and Vase shaped crown. Harvest, diameter, firmness, dry matter content and fruit weight were determined. The trees started to yield in the third year after planting. The harvest in the second year of yielding was 4-5 kg/tree. The average harvest in the third year of yielding was 9640-13290 kg/ha. For all three varieties the harvested quantity and fruit size were correlated with the crown shape. The Ameliorated Slender Spindle crown provided the highest production per hectare, while the Flattened Vase Shaped crown provided the lowest yield but had the highest values of the fruit size (28.2-28.4 mm) and of the soluble dry matter in the fruit (17.9-18.6 Brix%).

Background. The main trend in melon breeding is the development of cultivars with good taste, high yield, and disease resistance. The task may be solved through a scientific search for new source material meeting these requirements.Materials and methods. The research was performed at Bykovsky Cucurbit Breeding Experiment Station. Melon accessions of various origin and F1 hybrids from the nursery of source material served as the research material. In total, during the period of 2015–2017, over 100 melon accessions were studied: 45 accessions from the VIR collection, 61 from various companies, and 12 developed at various research institutions. In the nursery of source material, the accessions were hybridized and the resulting hybrid combinations were tested, including tests against infections. All of them were evaluated for their economically useful traits, yield, taste qualities, and resistance to bio- and abiostressors. During the trials they were compared with the best released cultivars approved for dryland conditions according to the developed guidelines.Results. The purpose of this work was to study the genetic collections of melons and obtain new source forms for further breeding. As a result of the study of the collection material, 12 accessions were identified with the following economically useful traits: high yield (exceeding the reference by more than 20%), high dry matter content (from 14 to 19%), large fruit size (fruit weight higher than 4.0 kg), and other features. After hybridization and testing in F1, the following 5 hybrid combinations were distinguished: Ekler × Osen; Dyuna × Mayskaya, Sheker and No 323; Katyusha × Mestny (k-7459, Georgia); Harmony × Mestny (k7461, Georgia), characterized by a set of features important for breeding.Conclusion. Thus, for further improvement by breeding and release of new melon cultivars, source accessions were selected with a yield exceeding 15.0 t/ha, dry matter content of 13.0%, bright fruit color, and resistance to diseases.

Vegetative Organs

The dry matter and moisture contents of the aboveground vegetative organs and kernels of four maize hybrids were studied in Martonvásár at five harvest dates, with four replications per hybrid. The dry matter yield per hectare of the kernels and other plant organs were investigated in order to obtain data on the optimum date of harvest for the purposes of biogas and silage production.It was found that the dry mass of the aboveground vegetative organs, both individually and in total, did not increase after silking. During the last third of the ripening period, however, a significant reduction in the dry matter content was sometimes observed as a function of the length of the vegetation period. The data suggest that, with the exception of extreme weather conditions or an extremely long vegetation period, the maximum dry matter yield could be expected to range from 22–42%, depending on the vegetation period of the variety. The harvest date should be chosen to give a kernel moisture content of above 35% for biogas production and below 35% for silage production. In this phenophase most varieties mature when the stalks are still green, so it is unlikely that transport costs can be reduced by waiting for the vegetative mass to dry.

Цель исследований – дать оценку сохраняемости и болезнеустойчивости современных сортов и гибридов моркови столовой и определить корреляционные зависимости влияния биохимических показателей качества на сохраняемость и степень поражения моркови столовой различными видами болезней в процессе хранения. Исследования проводились в 2011–2016 годах во ВНИИО – филиале ФГБНУ ФНЦО по общепринятым методикам. В биохимической лаборатории отдела земледелия и агрохимии содержание сухого вещества определяли высушиванием до абсолютно сухого веса, общего сахара – по Бертрану, аскорбиновой кислоты – по Мурри, нитраты – ионоселективным методом. При характеристике моркови столовой важнейший показатель, определяющий его качество – количество сухого вещества и сахаров. В процессе хранения были выявлены следующие болезни моркови: серая гниль (Botrytis cinerea Pers. ex Fr.), белая гниль (Sclerotinia sclerotiorum (Lib.)), белая парша (Rhizoctonia carotae Rad.), альтернариоз (Alternaria radicina M., Dr. et E.). В большей степени сортообразцы моркови столовой поражались серой гнилью. Лучшими по сохраняемости сортообразцами были Корсар (94,6%), F1Берлин (94,5%), Берликум Роял (94,1%) и F1 Звезда (94%). Сохраняемость у зарубежных сортов и гибридов моркови столовой была немного выше, чем у отечественных (на 0,4%) как за счет меньшей величины убыли массы (6,3% против 6,4%), так и потерь от болезней (1,6% против 1,9%). Сохраняемость корнеплодов моркови находится в прямой корреляционной зависимости от содержания сухого вещества (r=+0,41), каротиноидов (r=+0,39), моносахаров (r­=+0,30) и суммы сахаров (r=+0,27). Проявление серой гнили находится в обратной корреляционной связи с содержанием сухого вещества и каротиноидов (r=-0,37 и r=-0,35 соответственно), белой парши – в прямой корреляции с содержанием сухого вещества , моносахаров и дисахаров (r= +0,21; r= +0,39; r= -0,41 соответственно), белой гнили в обратной корреляционной связи с содержанием сухого вещества, моносахаров и дисахаров. The purpose of the research is to assess the persistence and disease resistance of modern varieties and hybrids of carrots and to determine the correlation between the influence of biochemical quality indicators on the persistence and degree of damage to carrots by various types of diseases during storage. The research was conducted in 2011–2016 at ARRIVG – branch of FSBSI FSVC, according to generally accepted methods. In the biochemical laboratory of the Department of Agriculture and Agrochemistry, the dry matter content was determined by drying to absolutely dry weight, total sugar – by Bertran, ascorbic acid – by Murri, nitrates – by the ion-selective method. When describing carrots, the most important indicator that determines its quality is the amount of dry matter and sugars. During storage, the following diseases of carrots were detected: gray rot (Botrytis cinerea Pers. ex Fr.), white rot (Sclerotinia sclerotiorum (Lib.), white scab (Rhizoctonia carotae Rad.), alternariasis (Alternaria radicina M., Dr. et E.). To a greater extent, varieties of table carrots were affected by gray rot. The best preserved varieties were Corsar (94.6%), F1 Berlin (94.5%), Berlicum Royal (94.1%) and F1 Zvezda (94%). The persistence of foreign varieties and hybrids of table carrots was slightly higher than that of domestic ones by 0.4%. both due to a smaller amount of weight loss (6.3% vs. 6.4%) and losses from diseases (1.6% vs. 1.9%). The persistence of carrot root crops is directly correlated with the content of dry matter (r=+0.41), carotenoids (r=+0.39), monosaccharides (r=+0.30) and the amount of sugars (r=+0.27). The manifestation of gray rot is in inverse correlation with the content of dry matter and carotenoids (r=-0.37 and r=-0.35, respectively), white scab is in direct correlation with the content of dry matter (r= +0.21; r= +0.39; r= –0.41, respectively), white rot is in inverse correlation with the content of dry matter, monosaccharides and disaccharides.
