“…Similar studies are known in 100-year-old pine cultures [4], in larch cultures [5], and in natural pine forests of different ages [6]. Several studies have been carried out abroad in different regions [7,8] and in tropical forests [9,10]. However, they have a slightly different, predominantly climatic orientation.…”

The purpose of the research is to identify trends in the change in radial growth, the width and structure of annual rings in forest-steppe and steppe pine ecotypes in 59-61-year-old geographical cultures. To achieve the intended goal, according to the methodology adopted in forest inventory, 32 trial plots were laid, on which the diameter of trees at a height of 1.3 m with an accuracy of 0.1 cm and the height with a Blume-Leiss altimeter with an accuracy of 0.1 m were measured with a measuring fork. area (PP) from 3 trees of average diameter and height, radial wood cores were taken with a Haglof-60 age borer at a height of 1.3 m. After dating the growth rings of wood, their width was measured at the Lintab-6 complex, divided into early and late. The obtained data were statistically processed using the programs Statistica 8.2 and Excel-10. In the forest-steppe and steppe ecotypes, the trends of radial growth were determined and their features with age were revealed. So, up to 10 years it increases, then sharply decreases and after 20 years it stabilizes.

“…As well, they helped in well recognition between density fluctuations if any, and ring boundaries. That was not the case in some Amazonian trees that were explored for their ring formation where microscopic sections did not help in well recognition of growth rings ( Rodriguez et al., 2022 ). A few samples (1-2 samples per species) had indistinct ring boundaries in one or two positions or had stain deposits in the wood that prevented the recognition of the ring borders properly.…”

“…Tropical and subtropical lands are the most biologically diverse, productive, and poorly studied environments in the world ( Corlett, 2018 ; Deharveng and Bedos, 2019 ). However, dendrochronologists have long shied away from them due to the frequently inconsistent growth patterns of tropical trees, challenging sampling conditions, complex wood anatomy, and/or a lack of physiological understanding of local wood species ( Pearl et al., 2020 ; Rodriguez et al., 2022 ). Recently, for tropical and sub-tropical tree species, studying tree growth by using the annual tree rings is becoming essential for more understanding of the ecological performance of trees ( Farahat and Gärtner, 2019 ; Quesada-Román et al., 2022 ).…”

In tropical and subtropical regions, much research is still required to explore the dendrochronological potential of their trees. This study aims to evaluate the anatomical structure and dendrochronological potential of three Mediterranean desert shrubs in Egypt (Lycium schweinfurthii var. schweinfurthii, L. europaeum, and Calligonum polygonoides subsp. comosum) supported by X-ray density. The results showed that the target species had distinct growth rings at macroscopic and microscopic levels. The vessel traits reflected the adaptability of each species with the prevailing arid climate conditions. After the exclusion of the non-correlated series, we obtained three site chronologies that cover the years 2013-2022 for L. schweinfurthii, 2012-2022 for L. europaeum, and 2011-2022 for C. comosum. The mean series intercorrelation was 0.746, 0.564, and 0.683 for L. schweinfurthii, L. europaeum, and C. comosum, respectively. The EPS (expressed population signal) values ranged from 0.72 to 0.80, while the SNR (species-to-noise ratio) ranged from 9.1 to 21.5. Compiling all series of L. schweinfurthii raised the EPS value to 0.86. The chronologies developed for the studied species were relatively short since we dealt with multi-stemmed shrubs. The average percentage difference between latewood density (LWD) and earlywood density (EWD) in C. comosum, L. europaeum, and L. schweinfurthii were 11.8% ± 5.5, 5.2%± 1.87, and 3.6% ± 1.86, respectively. X-ray densitometry helped in the precise determination of the ring borders of the studied species. The relationships between the radial growth of the studied species and the climate variables were weak to moderate but mostly not significant (i.e., r < 0.7). Generally, the radial growth of the target species had a weak to moderate positive correlation with temperature and precipitation during the wet season (winter), while negatively correlated with temperature for the rest of the year, particularly in summer. Our data agrees with earlier findings that ring formation starts at the beginning of the long vegetative stage, then the rest of the assimilated carbohydrates are directed to the flowering and fruiting at the end of the vegetative stages. For more efficient dendrochronological studies on subtropical and Mediterranean trees, we recommend carrying out xylogenesis studies, collection of phenological data, sampling 45-80 trees per species, using new techniques, and choosing homogeneous and close sites for wood sampling.

“…In sapwood and heartwood, the Ca chemical species are distinct [ 28 ]. Thus, it can be served as a chemical marker for wood traits (e.g., wood anatomy and density) [ 29 , 30 ]. In addition, Ca:Mn ratios can be used as early-warning signals of forest dieback [ 31 ], and Ca physiology is considered to associate with the structure and function of forest ecosystems [ 32 ].…”

Calcium and magnesium are major nutrient elements of plants, and both play an important role in plant growth and development. Pinus massoniana and P. hwangshanensis are important afforestation tree species in barren mountains in China. However, observation and research on calcium and magnesium nutrition of dominant forest species in China are still limited. This study determined the concentration of calcium and magnesium in needles for two species from five sites in East China by inductively coupled plasma optical emission spectrometry (ICP-OES). We then explored the inter- and intra-population variation pattern of calcium and magnesium and their relationship with environmental factors. There were significant differences in traits among populations. The strongest factors, which impacted the variation of calcium and magnesium concentration, were elevation and individual differences, respectively. Element concentration was correlated to environmental factors such as longitude, latitude, elevation, and mean annual temperature. The results of this study can be helpful for a better understanding of tree growth, population survival, and forest succession.
