Special Issue Information

Dear Colleagues,

Climate change has caused more frequent extreme drought events, which increasingly threaten ecosystem function and services and weakens the potential to mitigate climate change. Declines in tree growth and/or adjustments in wood anatomy have emerged as consequences and a potential adaptive acclimation in woody plants. These biological processes include physiological responses in the seasonality of wood formation as well as structural and hydraulic adjustments in different plant organs at the multi-year scale.

Understanding the impacts of drought on tree growth and wood anatomy at different time scales is pivotal for assessing drought effects on forest ecosystem functioning and providing useful management options for forest adaptation. We are pleased to invite researchers to contribute to this Special Issue focusing on “Drought Impacts on Wood Anatomy and Tree Growth”.

The aim of this Special Issue is to assemble related data to advance our understandings of drought impacts on forest growth, productivity, and wood anatomical properties. Studies using retrospective, modeling, and observational approaches, including but not limited to dendrochronology, wood anatomy, micro-coring, dendrometer, sap flow, etc., are welcome.

We look forward to receiving your contributions.

Primary and secondary growth of trees are key components of carbon sequestration in forest ecosystems. However, the temporal relationships between primary and secondary growth as well as their responses to environmental variations are still poorly understood. Herein, we continuously measured the intra-annual leaf, shoot and stem growth of Quercus serrata for two years on Lushan Mountain, southeastern China. Our results showed that shoots were ranked as the first organ to initiate, peak and cease growth, rather than leaves and stems. Moreover, the phenological stages of shoot growth were negatively associated with those of leaves and stems, whereas there was a weak positive correlation in phenological events between leaves and stems. These temporal connections in phenological events between primary and secondary growth suggest a prioritized carbon allocation to shoot growth and a high dependence of stem growth on carbon from newly developing leaves. Although stem growth started earlier in response to the warmer spring in 2018 compared to the colder spring in 2017, no significant difference in annual increment was observed between years, which was related to the more severe drought condition during the dry season in 2018. At the intra-annual scale, different organs generally had a consistent growth response to temperature variables but showed a divergent response to vapor pressure deficit. Despite a relatively short observational period and potential bias in spatial representativeness, our data provide nuanced knowledge on seasonal growth dynamics in primary and secondary of broadleaved species, underlining the importance of jointly considering intra-seasonal variabilities of environmental conditions in order to correctly predict tree growth response to climate change in subtropical regions.

The exploration of the genetic resources of drought-resistant trees is highly significant for improving the ecological environment. Elm trees are widely distributed in the cold and arid regions of the Northern Hemisphere and have a strong tolerance for adverse conditions. This study evaluated the drought tolerance of 20 elm varieties (Ulmus pumila L.) collected from areas subject to varying degrees of drought and cold. By assessing phenotypic and growth indicators, we found that the drought-sensitive varieties ULP-2 and ULP-3 exhibited a significant reduction in height (31 cm and 16 cm) and root collar diameter (0.37 cm and 0.17 cm), whereas the drought-tolerant varieties ULP-19 and ULP-12 maintained favorable growth conditions under drought stress. Moreover, ULP-19 and ULP-12 displayed significantly fewer yellow leaves (12 and 19) and greater root biomass (237.8 g and 221.2 g). Compared with the sensitive varieties, the relative water content in leaves (21.02% and 30.10%) and roots (26.13% and 34.53%) decreased less in the drought-tolerant varieties. Transcriptome sequence analysis showed that the stable drought resistance of the drought-resistant variety ULP-19 is associated with changes in the processes of carbohydrate metabolism and lignin synthesis in the roots, and these processes are governed by an increase in the regulation of transcription in the leaves of protective pathways controlled by calcium ions and phytohormones (abscisic acid). These results will aid in the selection of appropriate elm varieties for afforestation initiatives and the development of sustainable forest ecosystems in arid regions. Full article
