“…Low emissions of e.g., nitrogen dioxide and sulfur dioxide, can favourably affect the annual radial increments in moderately and even in intensively contaminated zones [19]. However, the impact of industrial emissions on TRW may vary and depend on, among others, the stage of the life cycle of the described species or the distance and direction of the location of the onerous plant relative to the forest areas studied [27,29]. The most serious damage to the relict Scots pine forests located in the north-eastern part of the Czech Republic can be attributed to chemical synergism (SO 2 , NO x and O 3 ) and meteorological stress, especially in combination with the long-term occurrence of the drought period [25].…”

Changes in annual tree ring width (TRW) and its size depends not only on the changing climate and natural stress factors such as extreme air temperatures, shortages in rainfall and excess rainfall during the growing season, but also on anthropogenic stress, including chemical compounds emitted to the atmosphere or lowering of the groundwater table caused by the operations of plants with high environmental impact. The purpose of this article is to assess the impact of meteorological conditions and anthropogenic factors on the size of annual growth of Scots pine tree-stands in the conditions of the climate of central-eastern Poland. On the basis of five created site chronologies in the vicinity of Zakłady Azotowe Puławy (nitrogen factories in Puławy) and using the moving correlation analysis and multiple regression analysis, a significant influence of temperature and precipitation conditions on the TRW size is proved. A significant, positive influence of air temperature on TRW was proved for the majority of chronologies created in the period of January–March, as well as in June, while it remained negative in May. The wide rings of Scots pines were formed when the precipitation of October and January (prior to the resumption of cambium activity) was lower than the average, and higher in April and in June–August. After including the anthropopressure factors in the regression equations, the description of the variability of the annual tree ring width was corrected. The coefficient of determination ranged from approx. 29% to even above 45% and was higher, on average by 10%, for all studied chronologies of Scots pine compared to the one calculated for constructed equations considering only meteorological conditions. The strength and direction of the impact of the independent variables (SO2, NH3, NOx) analysed on TRW mainly depended on the distance from the plants, as well as on the direction of inflow of industrial pollution to the stands examined. In light of the proven climate changes in central and eastern Poland, the growth conditions of pine stands will most likely deteriorate.

“…If we class these changes as adaptive, then it is unclear why they manifested themselves precisely at the critical level of needles pollution, when the pollutants content in it is the highest, biochemical protective reactions are suppressed, although they occur even under heavy pollution (Kalugina et al 2018).…”

“…We have previously considered biochemical and physiological indicators and found out that technogenic pollutants cause metabolic disturbances showing in the development of oxidative stress as a result of excessive generation of reactive oxygen species (Kalugina et al 2018). The great importance of peroxidase and nonenzymatic antioxidants (ascorbic acid, glutathione, phenolic compounds, proline) in preventing oxidative damage to assimilation organs caused by pollutants was demonstrated (Kalugina et al 2021;2022).…”

Species-speci c anatomical and morphological changes of Scots pine and Siberian larch needles were studied at different levels pollution by aluminum smelter emissions. Anatomical parameters were found to change nonlinearly in polluted needles as a result of pathological exposure to pollutants. In pine, negative anatomical changes include the following: reduction of the cross-sectional area of needles, central cylinder and conductive bundles, reduction of the thickness of the external tissues and mesophyll, reduction of resin channels and a decrease in their diameter. At a critical level of pollution, when the content of pollutants in pine needles reaches maximum values, certain changes in anatomical parameters in the remaining green needles are presumably adaptive. In larch needles at low, moderate and high levels of needles pollution, the anatomical changes found can be classed as adaptive -this is an increase in needles mass, thickness and width, thickness of the epidermis, mesophyll, cross-sectional area of needles. Larch needles, even at a critical pollution level, show no signi cant anatomical abnormalities. Negative morphological changes of pine include a decrease in the size of needles and shoots, their mass and the number of needles on shoots, in larch -a decrease in the length of needles and shoots, the number of brachiblasts. The results obtained suggest that indicators of the development of pathological processes in both pine and larch exposed to pollution are changes in the number of visual and morphological parameters of tree needles and shoots. Both showed a high level of correlation with the content of pollutants in the needles.

“…light, temperature, humidity (Deng et al, 2018). In addition, vitamin C content in pine shoots, varies depending on the season of the year or the pollution level (Kalugina et al, 2018). Temperature and relative humidity are among the most important factors influencing the change of coloration and thus pigment degradation (Shahabi et al, 2014).…”

Scots pine (Pinus sylvestris L.) shoots have been increasingly commonly used as functional food or its component, the shoots contain various active components, unknown from other raw materials. The objective of the study was to assess the influence of the drying method on the content of bioactive compounds and antioxidative and antimicrobial activity of pine shoots. It was demonstrated that freeze drying (PSL), vacuum drying (PSP) and natural drying (PSN) have significant impact on the physicochemical properties, content of bioactive compounds and antioxidative activity of the prepared ethanol-water extracts. The content of the studied compounds varied significantly in the tested shoots. In spectrophotometric testing the highest total flavonoid content was demonstrated in the PSP sample, at 5.51 mg quercetin/g dw. On the other hand, the reducing capacity was as follows: PSN>PSP>PSL in the range from 13.4 to 5.73 mg gallic acid/g dw. However in assay conducted using HPLC methods the highest content of polyphenols characterized extract from freeze-dried raw material (9151.15 µg/g), followed by vacuum-dried (8264.57 µg/g), and the lowest content of phenolic compounds was found in convection-dried shoots (7621.76 µg/g). The studied extracts demonstrated antioxidative properties, both in ferric reducing antioxidant power assay (FRAP) as well as in free radical quenching measurement (DPPH). All of the studied extracts demonstrated antimicrobial and fungicidal properties, and they were particularly efficient in the case of gram-negative bacteria.
