“…The parameters of bioelectric potentials (bioelectric potential, moisture of needles and shoots, speed of water flow, osmotic potential, impedance of the cambial complex of tissues, stem temperature) can be meaningful indicators for determining the degree of stability of trees in a plantation. Using these traits even allows an early diagnosis of trees regarding their stability and productivity [128,129].…”

Heterobasidion annosum (Fr.) Bref. sensu lato (s.l.) is a dangerous forest pathogen causing root and butt rot disease in most conifers of the northern hemisphere. This pathogen is most widespread in the forests of Europe and North America. The economic impact on forestry related to tree mortality, reduction in timber yield, and wood rot is calculated in millions of dollars and euros. The genus Heterobasidion (Basidiomycota; Russulales) has been relatively recently separated into three genetically distinct groups (H. annosum, H. insulare and H. araucariae) comprising a total of 12 species and one newly described hybrid taxon. These species are the best studied in terms of the ecology, the physiology of control methods, and the tree’s resistance to the pathogen. The article gives an overview of the symptoms and the etiology of the disease and provides information on ways to recognize the disease and limit the economic damage.

“…Only temperatures exceeding 47 °C appear to be fatal in the wild, but such temperatures only stay for a few hours and the bark beetles survive this without loss. Karasev et al (2017) used semiconductor thermoresistors to detect trends in stem temperatures of Scots pine in different groups based on the physiological state of trees. The temperature was found to have a strong inverse correlation with the state of the trees, confirming that the method of assessing physiological state using temperature parameters allows early diagnosis of decreased viability of conifers.…”

Biogeosciences and ForestryBiogeosciences and Forestry Determination of differences in temperature regimes on healthy and bark-beetle colonised spruce trees using a handheld thermal camera Andrej Majdák (1) , Rastislav Jakuš (1-2) , Miroslav Blaženec (1) In this study, we compared the daily temperature regimes of healthy uninfected trees in the interior of a forest stand and at the fresh forest edge with infested trees at the forest edge in an area affected by a bark beetle outbreak. We estimated the potential of a handheld thermal camera for early identification of bark-beetle infested trees. We show that infested trees have significantly higher trunk temperatures than uninfested trees, which is more visible on the shine side of the trunk, and we report the differences in temperature between the shine and shadow sides. The differences are more noticeable on a warm, bright, and sunny day than on cold and cloudy day. The different intensity of solar radiation does not affect the distinction between infested and uninfested trees. The handheld thermal camera shows potential for identifying bark-beetle infested trees by scanning tree trunks on bright sunny days.

“…They are trying to use the electrical response of plants to changes in the environment to determine optimal growing conditions, increase plant productivity, and study reactions to external stimuli. Compared to labor-intensive methods for assessing the condition of plants based on morphological characteristics, which give a 50% error, monitoring the electrical activity of plants seems to be more accurate, efficient and effective [4]. Implemented in automated systems, such monitoring simplifies the solution of problems of operational diagnostics, warning and forecasting [5].…”

The subject of the study is the time series of the difference in electrical potentials along the trunk of a pine tree and the time series of meteorological and geomagnetic parameters consistent with them, measured by hardware and software complexes of the geophysical observatory "Petrozavodsk" and the Botanical Garden of Petrozavodsk State University in 2017-2022, as well as the time series of the K-index database global geomagnetic activity. The existence of characteristic regimes in the difference in electrical potentials of pine trees is shown, depending on the season, temperature, precipitation, humidity, determined by physical environmental factors and physiological processes in the tree. The reaction of the electrical potential difference of pine trees to meteorological parameters, thunderstorms, and space weather phenomena: magnetic storms and solar eclipses is analyzed. The results of these observations are qualitatively interpreted using known features of electric field of the Earth.
