Authors: Wazir Zuber Angkasa , F Anwar Widya Fransiska 
Published: June 2020

Masyarakat Indonesia adalah masyarakat yang kolektif karena memandang kepentingan kelompok lebih penting daripada kepentingan pribadi. Walau demikian, karakter ini semakin berkurang seiring berkembangnya ekonomi. Hal ini semestinya ditunjukkan dari aspek adaptasi secara arsitektural rumah panggung. Penelitian ini memeriksa adaptasi ini pada sembilan rumah panggung yang ada di Kawasan 9 Ilir Kota Palembang. Rumah-rumah ini dibangun pada periode 1928 – 1964 dan terus bertahan hingga sekarang. Karenanya, kami juga berkesempatan menguji teori periodisasi adaptasi arsitektur dari Brand dan Schmidt et al. Berdasarkan periode perubahan material kolong dari segi tempat, struktur, dan bidang ruang, disimpulkan bahwa teori Brand lebih sesuai dengan konteks rumah panggung. Sementara itu, terkait penutupan dan pembangunan kolong, dapat disimpulkan bahwa telah terjadi perubahan fungsi kolektif menjadi individual namun kembali bergeser ke arah kolektif.

According to the results of the field researches, the state of the natural complexes of the territory (about 140 hectares) within the Yampil administrative district of Sumy region is characterized, the expediency of creation of a landscape reserve of the local value "Govorunovsky" in the studied territory is determined.
Based on the analysis of flora and vegetation, it has been established that most of the territory of the proposed reserve is occupied by peaty meadows dominated by Deschampsia caespitosa (L.) Beauv and a number of typical meadow and meadow-swamp species. They are also growing here Filipendula ulmaria (L.) Maxim., Lysimachia vulgaris L., Veratrum lobelianum Bernh., Cicuta virosa L., Alopecurus pratensis L., Festuca pratensis Huds., Juncus conglomeratus L., Carex hirta L., Ranunculus acris L., Achillea submillefolium Klok. et Krytzka, Epilobium palustre L., Geum urbanum L., Galium mollugo L., Stellaria graminea L., Potentilla anserina L., Humulus lupulus L. In the more dry areas which are strip-shaped along the northern boundary of the projected reserve and, accordingly, the pine forest, grassy groups formed with the dominance of Agrostis canina L. or Nardus stricta L.
It is noted that quite active natural restoration of tree species, such as Pinus sylvestris L., Betula pendula Roth, Pyrus communis L., occurs throughout the area of the proposed reserve.
It has been shown that the sozological value of the reserve lies in the presence of typical for the floodplains of small rivers of Polissya natural complexes, as well as the presence in the flora of the species of the Red Book of Ukraine ‒ Dactylorhiza fuchsii (Druce) Soo, a number of valuable medicinal plants (Valeriana exaltata J.

Studies were conducted during 2017‒2019 based on the training laboratory of horticulture and viticulture of the Sumy National Agrarian University in the conditions of the North-Eastern Forest-Steppe of Ukraine. It was found that the pear was massively affected by rust. This is a fungal disease that was rarely found in fruit orchards of the North-Eastern Forest-Steppe of Ukraine.
Rust infected pear trees very rarely in previous years. Only single spots were found on the leaves of the pear. Since 2015, the development of the disease has noticeably accelerated from year to year. There was a massive rust damage of the pear in the region in 2019. The prevalence of the disease reached 100 % in almost all varieties. Mostly the leaves were affected, not to a large extent the shoots of the pear. On the fruits of the external signs of the disease were not detected.
During the years of research, weather conditions were optimal for the spread of fungal diseases. Only the aecial stage of the fungus was observed on the pear. The aecial stage of the pathogen is the most harmful. Affected pear leaves fall prematurely. Studies were conducted on pear varieties Lymonka, Petrovska, Medova, Osinnia Yakovlieva, Chyzhovska, Noiabrska, Bere Desiatova, Uliublenytsia Klappa, which showed different degrees of rust damage. The disease manifested itself most significantly (5 points) on the varieties, Uliublenytsia Klappa and Bere Desiatova. Not one of the varieties did not show high resistance to the pathogen. The pear of the Chyzhovska variety was less affected, with a defeat score of 3 (18.8 %) in 2017 and 4 (32.3 % and 44.1 %) in 2018‒2019.
It is known that the life cycle of the rust pathogen Gymnosporangium sabinae (Dicks.) G. Winter occurs on two plants: pear and juniper. The pathogen from juniper goes on the pear and vice versa. Pear trees do not become infected from each other. On the territory adjacent to the fruit garden of Sumy National Agrarian University, a survey of plantings of different types of juniper was conducted. There were no visible signs of the disease on the juniper. At the same time, pear trees were highly infected with the pathogen. Perhaps the spores of the fungus can spread far through air currents. But at the same time, possible changes in the life cycle of the pathogen in the conditions of this region. Clarification of this circumstance requires deeper further research.

Published: June 2020

The problem of using alternative energy sources from renewable feedstock is becoming more and more of great current interest for modern society due to energy crisis and ecological situation which is getting worse. Among many high-yielding plants, perennial cereal miscanthus is an appreciable one for producing biofuel in the form of fuel granules.
Cultivating phytoenergetic cultures it is important to apply fertilizers as an important component of the technology, which is aimed at raising yielding capacity of vegetative mass.
Unlike other cereals, culm of miscanthus is partially or fully filled with white soft pith. Joints at the bottom of the culm are quite short, and on the top part of the culm they can be of a large length due to the division of intercalary meristem.
Thus, during the growing season the largest amount of joints on the culm was in the variant N60 – 7.1 pieces which is more comparing with the control on 1.3 pieces and with N30 - on 0.9 pieces. At the end of the growing season the amount of joints raised slightly. Thus, in the control variant the amount of joints was 6.4 pieces, N30 – 7.3 pieces and N60 – 8.0 which is more comparing with the growing season on 0.6 – 0.9 pieces on the culm.
As the result of the estimated indices we defined the greatest amount of leaves in the growing season by the variant N60 – 9.5 pieces per culm, and the least amount was on the control 7.8 pieces per culm, in the variant N30 – 8.7 pieces per culm. The same tendency was at the end of the growing season. Thus, the largest amount of leaves on the culm was in the variant N60 – 10.5 pieces, on the control – 8.5 pieces, N30 – 9.8. The difference in leaves amount on the culm between growing seasons varied from 0.7 to 1.0 pieces.
At the end of vegetation the weight of plants was 48.5–77.0 g. The least weight of plants was on the control – 48.5 g which is more on 20.5 g than in the variant N30, and on 28.5 g of the variant N60. So the maximal weight was 77.0 gr in the variant N60.
The weight of dry plant on the control was 25.1 g, N30 – 32.5 g, N60 – 37.1 g. The maximal weight of dry plant was in the variant N60 – 37.1 g, that is more on 4.6 g in the variant N30 and 12 g on the control.
Pre-harvest density of miskanthus plants by apllying different dozes of fertilizers varied. Thus, the greatest density was in the variant N60 – 42 pieces per m2. The less density was got in the variant N30 – 38 pieces per m2 and the least density was on the control – 37.0 pieces per m2.
According to the analysis of yield capacity indices of miscanthus during the years of research and different variants we pointed out that the maximal yielding capacity as for fertilizer dozes was in the variant N60 – 15.58 tons per ha, that is more on 20.7 % than in the variant N30 (12.35 tons per ha) and on 40.4 % that in the control variant (9.29 tons per ha).
Features of the ontogenetic structure of Helichrysum arenarium L. (Asteraceae) coenopopulations in the different phytocoenosis under the conditions of the Shostka district, Sumy region (Ukraine)
Authors: Penkovskа L.V. 
Published: June 2020

The paper contains the characteristics of Helichrysum arenarium L. plants of various ontogenic stages and their percentage in six cenopopulations. On the ground of obtained results, conclusions are made regarding considering the ontogenic structure of H. arenarium cenopopulations in the conditions of Shostka geobotanical district, Sumy region (Ukraine). Complex assessment of the ontogenic structure of populations using a specialized software and conventional methodologies, showed that the majority of populations are represented by plants of 4–8 ontogenic stages. Most constant are the generative and old individuals present in all investigated cenopopulations. Based on the ratio of the age index and the efficiency index (values of Δ / ω), it was determined that majority cenopopulations are ageing. The value of the age index (by the method of Kovalenko I. M. [9]) is bigger than 1 in all investigated cenopopulations, suggesting the prevalence of degradation processes. According to the classification of T. O. Rabotnov, all investigated populations belong to the category of “normal”. All main characteristics of populations indicate their potential for sustainable existence in the study region. However, their viability appears to be different, with the most evident imitations being faced by the populations under the pine forest canopy (populations are incomplete as to the presence of various ontogenetic states). In contrast the populations growing in Pineto (sylvestris)–Aceretum (platanoiditis) helichryosum (arenarium) and Helichrysetum (arenarium) phleosum (pratense), аs well as Achilletum (millefolium) helichryosum (arenarium) is community distinguished by the most complete ontogenic structure. As a result of radical changes in natural ecosystems, there is a decrease in the populations of many species, which prompts us to find directions and ways of regulating the mechanisms of development of natural phytocenoses. As a promising scientific direction, the application of the morphometric and vital analyzes to the investigated cenopopulations for evaluation of sustainability parameters of the H. arenarium individuals in the studied area.
Manifestation of the average mass of commercial tubers in interspecific hybrids of potatoes, their backсroses depending on the place and years of the test
Authors: Kravchenko N.V. 
Published: June 2020

The successes in the selection of potato in the direction of creating varieties with a large average weight of commercial tubers depends on the quality of the source material, very desirable with the combination of high manifestation of the sign and the stability of its expression, regardless of external conditions. The researches were carried out in 2015–2017 under the conditions of the Ustymovskaya Research Station Plant (URSP) and the Sumy National Agrarian University (SNAU) in accordance with generally accepted methods in potato-growing. The starting material used different methods of creation, origin, degree of backing complex intraspecific hybrids with the participation of Mexican wild species. Significant potential of individual backcrosses has been revealed at the sign of a sign that is up to 1.8 times more than in the best grades. At the same time, he realized, depending on the external conditions is far from complete. Only in the most favorable for the meteorological complex in 2017, under the conditions of the SNAU, the proportion of hybrids having an average mass of one commercial tubers of more than 100 g was 75.8 %, and in the URSP it was 2,3 times less. The favorable conditions of the growing season of potato in 2017 are also evidenced by the proportion of hybrids with the maximum manifestation of the trait. In SNAU it was 28.3 %, and URSP – 25.3 %. The variability of the expression of the indicator at the test site is evidenced by the magnitude of its coefficient of variation. In the conditions of SNAU and URSP, the proportion of hybrids with a coefficient of variation of 10 % or less was 9.1 %. At the same time, in some hybrids the value of the indicator turned out to be very high – 50–70 %. Allocated hybrids, in which in each year the difference in the manifestation of the trait does not exceed 10–11 g, depending on the test site, namely: 90.673/30, 08.194/23 and 08.194/25, and in the hybrid 08.194/122 it was observed during 2015 and 2016 years. A different reaction of sister forms to the influence of the external complex was revealed. Among the hybrids 88.1450s2 and 88.1450s3 only in the latter under the conditions of the SNAU meteorological conditions almost did not affect the manifestation of signs – the coefficient of variation was 8%. With a difference of 1 g, the average mass of commercial tubers in this hybrid in the SNAU and URSP in 2015 was revealed. As a result of the study, it was possible to identify hybrids with a stable expression of the indicator irrespective of the meteorological conditions (08.194/25), for trials for three years in the SNAU (88.1450s3), URSP (08.194/33,08.194/119) and experimental locations (90.673/30,08.194/23 and 08.194/25). They are recommended for use in the breeding process with high adaptability.
