“…Conversely, tracheid structure showed a significant negative correlation with annual precipitation and precipitation during the wettest and driest seasons, implying that excessive moisture may inhibit tracheid growth, highlighting the regulatory role of water conditions on plant cell structure. These insights corroborate previous studies [86,87], underscoring the critical role of environmental factors in shaping plant cell structure. Nonetheless, it is essential to consider the variability across different tree species, geographical locations, and environmental conditions [88,89].…”

This research delves into the impact of climate change on the wood traits of Cunninghamia lanceolata across various altitudinal gradients, aiming to understand the influence of altitude and climatic factors like temperature and precipitation on key wood characteristics. Employing a comprehensive approach, samples were collected from different altitudes for detailed phenotypic analysis. Methods included Pearson correlation, principal component analysis, cluster analysis, and random forest analysis. Results revealed significant variations in wood traits such as heartwood ratio, tracheid length, and width across altitudes. Notably, wood traits in lower- and middle-elevation populations exhibited higher variability compared to higher elevations, indicating greater environmental diversity and genetic adaptability at these altitudes. Climatic factors, particularly temperature and precipitation, were found to increasingly influence wood trait variation with altitude. The research concludes that the adaptation of Cunninghamia lanceolata to climate change is significantly influenced by both altitudinal and climatic factors, highlighting their importance in forest genetic breeding and conservation strategies amidst global climate change.

“…Increased temperature boosts respiration, leading to higher material consumption by the tree. Consequently, the tree adapts to the high temperature environment by closing stomata on its leaves, indirectly affecting respiration, transpiration and photosynthesis, thus significantly reducing the xylem growth rate [47,48]. Qin [49] and others found that high temperatures affected the metabolic processes and activities of biological enzymes in Populus euphratica.…”

The anatomical characteristics of xylem and their relationship with temperature during the year can be studied at the cellular scale by using micro-coring technology and the wood anatomy method. In this study, we used Populus euphratica Oliv. trees with different groundwater burial depths in the lower Tarim River as the research subjects. Micro-core samples of Populus euphratica were collected near two sampling sites, TY1 and TY2, which have different groundwater burial depths. We analyzed the differences in xylem anatomical characteristics and their relationship with extreme temperatures under these varying groundwater conditions using wood anatomy methods. The results showed that the anatomical parameters at TY1, with a higher groundwater table, were greater than those at TY2, which had a lower groundwater table. Specifically, the conduit density, total conduit area, average conduit area and maximum conduit area of Populus euphratica xylem were significantly and positively correlated with both maximum and minimum temperatures. The principal components of xylem parameters at TY1, with the higher water table, were significantly and positively correlated with both maximum and minimum air temperatures. In contrast, the principal components of xylem parameters at TY2, with the lower water table, were not significantly correlated with either maximum or minimum air temperatures. The sensitivity analysis indicated that the sensitive maximum air temperature for the principal component parameter index change of Populus euphratica xylem was 34.1 °C, and the sensitive minimum air temperature was 16.1 °C. Therefore, different moisture conditions affected the sensitivity of xylem parameter growth to temperature, with the temperature threshold for Populus euphratica xylem growth being between 16.1 °C and 34.1 °C.

“…Journal of Geophysical Research: Biogeosciences T min means a longer growing season, which directly determines the formation of a wider or narrower ring by affecting the accumulation of photosynthetic products (Fritts, 1976;Lv & Zhang, 2013;Zhu et al, 2015). Many studies have found that temperature, especially T min , has a direct impact on cell division, differentiation and enlargement of vessel and tracheid elements of broadleaf trees (Fonti et al, 2010;Fritts, 1976;Zhu et al, 2017). A higher daily T min in the early (May) or late (August and/or September) growing season can directly reduce the occurrence of freezing injury (Fritts, 1976;Kidd et al, 2014).…”

We used a dendrochronological approach to identify the spatial variability in growth‐climate relationships of Amur cork tree (Phellodendron amurense), using a network of 12 sites across its natural range in Northeast China. Results showed that the signal‐noise ratio, expressed population signal, and mean interseries correlations of the site chronologies decreased significantly with decreasing latitude. Correlation matrix, cluster, and rotated empirical orthogonal function (EOF) analysis all indicated that the 12 chronologies can be classified into two groups, the southern and northern chronologies. Minimum temperature (Tmin) was a major factor limiting Amur cork tree growth at regional scales. Almost all sites had positive correlations with monthly temperature, while correlation coefficients with precipitation were much lower than minimum temperature correlations, and only a few months (January, April, and July) were significant (p < 0.05). The positive effects of summer Tmin on tree growth were significantly decreased with increasing latitude (except BSL site), while positive effects of summer precipitation increased significantly with latitude and longitude and decreased significantly with altitude. The southern nine site chronologies (EOF‐1) were significantly positively correlated with the seasonal or annual Pacific Decadal Oscillation (PDO) index of the previous year and the current spring, while the northern three chronologies (EOF‐2) showed different relationships, which is consistent with the spatial relationship between PDO and local temperature. The spatial variability in growth‐climate relationships of Amur cork tree can be affected by PDO, which can modulate the spatiotemporal variation of spring onset, autumn termination, and the effective accumulated temperature by affecting local temperature.
