The aim of this paper was to evaluated of some apricot genotypes grown in the Romanian North Eastern area conditions. During 2016-2018 studies were done at seven apricot cultivars (‘Mamaia’, ‘Ovidiu’, ‘Fortuna’, ‘Amiral’, ‘Goldrich’, ‘Traian’ and ‘Dacia’) which were in the experimental plot at RSFG Iaşi, Romania. Number of days and sum of the active temperature from swelling buds (51 BBCH stage) to the beginning of blooming (61 BBCH stage), trunk section area of the tree and also fruit’s weight were evaluated. Fruit weight of ‘Dacia’ registered 89.3 g but at ‘Amiral’ were 75.3 g as average for three years, but statistically there were no significant differences from the average. Regarding the period from the swelling of buds to blooming, the shortest period was of 10 days for the ‘Dacia’ and ‘Traian’ and the longest period was 14 days for the ‘Ovidiu’. The sum of the active temperatures above the biological limit has varied according to the climatic conditions of the studied years from 103°C to the ’Dacia’ and ‘Traian’ to 136°C for the ‘Ovidiu’.

Maculipennis Complex

AbstractThe members of the Anopheles maculipennis complex have been incriminated for the transmission of the malaria in Europe, which was endemic until the middle of the century. The global warming and the intensification of the intercontinental travel constitute a risk of the re-emergence of the malaria in Europe, given the presence of the Anopheles vectors. The study has attempted the identification by using the PCR (Polymerase Chain Reaction) of the members of the Anopheles maculipennis complex from the North-eastern area of Romania from the city of Iaşi. In total there have been identified by using the PCR amplifying the ITS2 sequence of the ribosomal DNA, 217 specimens belonging to the complex of A. maculipennis among which: 58 A. atroparvus, 18 A. melanoon, 2 A. labranchiae, 52 A. maculipennis and 87 A. messeae. The ITS2 sequences of the ribosomal DNA have been compared to those of the species belonging to the A. maculipennis available in GenBank. The Species A. labranchiae is reported for the first time in Romania, being identified in the larval stage IV. The adaptation of a new species to the climatic conditions present in the North-eastern Romania, confirms the phenomenon of global warming and also the intensification of the travelling. As a result of the analysis of the A. labranchiae sequence, this one corresponds to the extent of 96% to the species from Italy, registered in GenBank, given the fact that a high number of the inhabitants of the municipality of Iaşi are working in this country.

Growth Vigor

During 1999–2016, the performance of ‘Red Bartlett’, ‘Conference’ and ‘Beurré Alexander Lucas’ grafted on four pear (Pyrus) rootstocks OH × F 69, OH × F 87, OH × F 230, OH × F 333 and on quince (Cydonia) rootstock BA 29 was evaluated at the RBIP Holovousy Ltd. For each combination, trunk cross-section area, cumulative yield, yield efficiency and mean fruit weight were assessed. The growth vigour of the scion cultivars on OH × F rootstocks was similar or slightly higher comparing to the growth on BA 29. Throughout the years, the growth vigor and productivity of the rootstock combinations may change. Less vigorous combinations of rootstock/scion were linked with higher yields in young trees, but usually with just moderate yields in later seasons. By contrast, combinations with higher growth vigour had usually higher yields in the later seasons. This balance is genotype specific, where aside of rootstock an important role is played by the scion cultivar vigour. The bearing precocity may be influenced by the cultivar as well. The results can vary with different climatic conditions and orchard management.

Abstract Due to the lack of maintenance, abandoned cemeteries are often incorporated into the landscape. In many cases the information about the age of the cemetery is unavailable. To find out the approximate time of the formation of the cemetery the information recorded in the annual tree and shrub rings can be used. One of the most common tree species, planted for ornamental and symbolic purposes on the cemeteries, are Thuja orientalis and Thuja occidentalis. Alien to the Polish flora, these species adapted well to the local habitat and climatic conditions. The paper presents an attempt to apply dendrochronological dating to determine the age of the abandoned cemeteries in the region of the Great Masurian Lakes, part of the Masurian Lake District (north-eastern Poland). The study included five abandoned cemeteries. In total, 15 cores were taken from the trees. After applying the standard dendrochronological method, local chronologies for the studied species were established. The research indicated that the oldest found specimens - over 70 yrs old - are Thuja occidentalis individuals growing at the Słabowo cemetery. At the other sites the specimens of both Thuja species date back to the 1960s and early 1970s. Compared to the historical information regarding the age and origin of the studied objects, thujas growing there are much younger than the age of the cemeteries foundation. The presented method proved to be very helpful in understanding the time of Thuja occidentalis and Thuja orientalis introduction at the investigated cemeteries.

The primary objective of the paper was to characterize the climatic conditions in the winter season in Poland in the years 1966/67–2019/20. The study was based on daily values of minimum (Tmin) and maximum air temperature (Tmax), and daily values of snow cover depth. The study showed an increase in both Tmin and Tmax in winter. The most intensive changes were recorded in north-eastern and northern regions. The coldest winters were recorded in the first half of the analyzed multiannual period, exceptionally cold being winters 1969/70 and 1984/85. The warmest winters occurred in the second half of the analyzed period and among seasons with the highest mean Tmax, particularly winters 2019/20 and 1989/90 stood out. In the study period, a decrease in snow cover depth statistically significant in the majority of stations in Poland was determined, as well as its variability both within the winter season and multiannual.

Yield And Quality

The strawberry cultivation is an important economic activity in the Rio Grande do Sul State, Brazil, however the number of offered cultivars to the growers is reduced. The yield and quality of strawberry (Fragaria x ananassa Duch.) cultivars Camarosa, Galexia, Earlibrite, Festival, Plarionfre and Sabrosa was evaluated under the climatic conditions of Pelotas, Rio Grande do Sul State. We determined the number, mass, total soluble solids (TSS ºBrix), total titratable acidity (TTA), antocianin level and fresh fruits produced in an experimental unit. We also determined the production of fruits per hectare and per plant. The statistical design used in the experiment was of completely randomized blocks with 6 treatments (cultivars) and 4 replicates where the experimental unit was composed of 8 plants. The harvest began in the first half of August, extending to the second half of December, totalling 20 weeks. Plarionfre, Earlibrite and Festival cultivars showed higher production from the first half of October until the end of the first half of November. Camarosa reached higher productivity, mass of plants and fruit weight. There were no differences between the evaluated cultivars in the levels of TSS, antocianin, ATT and pH during the period of evaluation.

Abstract Subsurface sediments in Poland were deposited mainly in the Pleistocene, and have varying origins and, consequently, differing geological and engineering parameters. Fluvioglacial deposits were formed during both the glacial and interglacial periods, which differed from each other in climatic conditions. Based on the results of laboratory analysis and fieldwork, till and fluvioglacial sands were compared in Central and North-Eastern Poland. The research included consistency limits, relative density, plasticity index, constrained modulus of initial compressibility and modulus of initial deformation. Despite the existing view that there exists a large diversity of geological, engineering and geotechnical parameters of variously-aged deposits in Poland, no major differences in their properties were determined at the study sites.

Geographical Position

The Old Red Sandstone plane of Caithness, with the geologically associated Orkneys, forms a homogeneous region comparatively isolated from the rest of Scotland by its geographical position and structure and by climatic conditions. Neither the physical geography nor the geology of the region need description here, except to note the absence of metals or similar mineral resources and the influence a stone that breaks easily and naturally along its bedding planes into flat slabs must exercise upon the local architecture. A word must, however, be said about the climate, which has not remained constant in prehistoric times.
