Consumption values of apple (Malus domestica Borhk) fruits subject to plantation construction
2013
В. В. Заморський
In the conditions of Forest Steppe Zone of Ukraine a long term (1977 to 2007) research were conducted over the construction of apple plantations of different pomology varieties using vegetative low height shoots and low height insertions. The analyzes of consumption values of Aidarder pomology variety yield throughout the entire fruit-bearing span certified that the major part of the harvest consisted of the fruits of the highest and the first commercial grades. Consumption qualities of Aidarder variety fruits over the early vegetation span significantly exceeded relevant indices registered for the period of 16 to 19 years of vegetation. That is, where the total of the highest and first grades ranged within 66% to 80% of the full harvest weight, two cuttings being grown, at the age of thirteen, then, as the age of the plantation was increasing the was decreasing, eventually to the range of 63% to 68% of the full weight of the fruits. Comparison of the data obtained on fruits marketability against the yield level over relevant period exposed a renowned in horticulture trend of marketability decrease due to high yield. As regards the planting constructions where the lo height insertions are used the Aidarder variety displayed higher marketability of fruits, however, the trend was not absolute. In some variants of the test (11 years old trees free of insertion, cutting in winter dates applied) the Rubinove Duky variety provided greater by 6,8% amount of higher quality fruits. The research over consumption value of the apple fruits has shown that these were changing irrespective of the construction and the age of the plantings. The augment of the first and the highest commercial grades is only possible with low height cuttings or insertions applied at summer dates for the procedure of cutting. The weight of apple fruits depended on the varietal properties and were increasing in the constructions of low height constructions as long as low height M.9 insertion was in use.

В. М. Горіна | О. О. Ріхтер | Б. О. Виноградов
In the component composition of volatile solutions determining fragrance of the flowers in apricot and cherry-plum varieties and Prunus brigantiaca Vill. x Armeniaca vulgaris Lam. hybrids there are 36 highest hydrocarbons and benzaldehyde that prevail. There are fewer amounts of the solutions which scare bees (benzaldehyde) in the fragrance of cherry-plum varieties as compared to the flowers of apricot and hybrids. At the same time, the content of tricosane, pentacosane, docosane, heneycosane, eicosane, nonadecan that probably attract bees is higher in the cherry-plum flowers than in the fragrance of apricot and hybrid flowers. The average three years yield of cherry-plum plants (Nikitska Zhovta 10,7 and Salgirskaya Rumjanaya 28,5 t/ ha) is higher than for apricot (Recolte de Schatene 0,3; Rodnik 2,9; Ananasniy Tsurupinsky 7,4 t/ha) and hybrids (8110 – 5,2; 8098 – 6,4 t/ha) that could be explained with better pollination of flowers and better fruit formation. Prevailing components of flower aroma of these plants and their possible link with yield of the objects in questions have been analyzed.

The article features results of studying suitability to processing for various varieties of onion as grown in the conditions of Ukrainian Forest-Steppe. A complex assessment has been completed for fresh products of onion for 9 different varieties by the content of basic biochemical, biological, economic, organoleptic characteristics with the view of determining the most suitable for drying. Varieties are singled out , which bulbs accumulate the biggest dry matter, sugar, C vitamin content and display the highest yield of consumable products. Assessment of dry products against the set of organoleptic and technological indicators has been completed. This revealed loss of basic biochemical components of onions during drying and long-term storage of dried products, as well as established increasing of the content of dry matters and acids and decreasing of that of sugars and vitamin C while storing the dried onion. The set of examined parameters

В. В. Поліщук
500 O-type lines of sugar beet hybrid components were studied according to their main economically valuable characteristics, namely, one-seed structure, germination readiness, productivity, sugar content and sugar yield. 13 best features were determined, herewith one-seed structure of most tested genotypes was observed at the level of 92-99% which appeared to be of nearly the same level during all the years of the research. On that ground they were included into the program for further research. The weight of seeds of the researched numbers ranged from 13,3 to 22,2 gr. The productivity of the researched O-type lines varied from 40,1 to 45,2 tons per hectare. Herewith, the highest productivity index was observed in 664bk 6 line with the average index 42,7 tons per hectare which ensured sugar yield 7,59 tons per hectare. The results of the research into the influence of low temperatures on seed germination readiness and capacity of O-type sugar beet lines were given. All the researched materials readily respond to conditions of germination and the seed germination readiness and germination capacity directly depend on the temperature. However, high indices of seed germination readiness and capacity under low temperatures is an essential feature of parent breeding materials in the breeding process while creating new hybrids which can be grown by means of intensive technologies. This will make it possible to sow heterosis sugar beet hybrids in earlier terms. It was suggested to use the best lines as parent components for development of heterosis hybrids which are able to ensure seed germination under low temperatures.

2013
Е. А. Козлова
The trend for development and spreading of diseases and pests of blackcurrant at Orel region in the conditions of extreme drought in 2010 has been detected. Abnormal weather conditions of the summer and the lack of precipitation limited both growth of host plant and disease spreading. At the background of extreme conditions of 2010 the crop phenophases shifted to earlier dates. The awakening of wintering pathogen structures began in the classic dates of the spring, although in summer their biological cycle went off rapidly. Due to the lack of moisture the disease pathogens failed to fully realize their potential of development and spreading. A favorable aspect of the extreme conditions of vegetation period, the reducing of the protective measures against diseases, is to be admitted. Abnormal weather conditions accelerated the pathogen biological cycles and reduced the stock of wintering infection; meanwhile they provoked colonization of the plants by pests. In extremely high air temperature and lasting lack of precipitation the pests number was intensively increasing, exceeding the maliciousness threshold. Due to the above some additional insecticide and acaricide treatments of berry crops were applied. Thus, the vegetation period of 2010 was described as most favorable for the development and spreading of pests and less favorable for disease pathogens.

В. О. Сіленко | П. М. Гав’юк
In the article the authors show outcome of three years observation of blackcurrant varieties bred by Study Horticulture Department NULES of Ukraine for their suitabi lity to machine harvesting. Blackcurrant is the most common berry crop in Ukraine. When establishing intensive industrial plantations the varieties suitable for machine harvesting should be used. During 2006-2008 limited and unlimited traits of varieties bred by NULES of Ukraine suitability to combine harvesting were studied. All parameters of the examined varieties were compared against the requirements of the «ideal variety”. Simultaneous ripening of berries was observed in varieties Dochka Vorskly – 93,6%, Hovtva, Pamyaty Leonida Myhalevskoho – 92,6%. The pick off effort required to collect berries out of their clusters for all varieties but Yarynka was within acceptable range of 67...129 g. By effort applied for berries crush only Yarynka has failed to meet the necessary requirements. All the varie ties but Yarynka have been found suitable by growth habit of their bush (upright and semi-spread). Insufficient number fruits (6-7 pc.) in clusters for varieties Narodna and Yarynka was noted. Berries weight for all studied varieties ranged within 1.27-1.84 g, their drop-off was 3-8%, duration of harvesting period ranged from 8 to 10 days, so all the parameters of varieties suggested they were suitable for picking berries by berry harvesters. Varieties Dochka Vorskly, Universitetska, Hovtva, Pamyatna, Premiera, Narodna, Leleka and Pamyaty Leonida Myhalevskoho were selected as suitable for combine harvesting by the complex of positive parameters.
