“…4.1. Females Were More Vulnerable to Water Deficit in Growth and Photosynthesis Than Males Water deficit causes plant yield loss through stunted plant growth or even mortality [14,61,62]. Plants that are more resistant to drought are typically able to maintain better growth under stress conditions [11].…”

Sexually dimorphic response to stress has been observed in assorted natural dioecious plants. Up to now, few studies have focused on the difference of stress responses between artificially bred siblings. To determine the sexual dimorphism between artificially bred sibling poplar trees, we conducted a study comparing the response to water deficit between male and female Populus × euramericana siblings. This pair of hybrids was analyzed in terms of growth, photosynthesis, membrane injury and repair systems, as well as gene regulation patterns. The female and male siblings presented distinct responses to water deficit, with greater inhibition in females’ growth and photosynthesis. The results also displayed that in females, relative electrolyte leakage and malonaldehyde content were higher than those in males under water deficit conditions. On the other hand, water deficit caused a greater increase in both SOD activity and POD activity in males than those in females. Consistent with these physiological differences, the expression of several stress-related genes, including SOD, GST, bHLH35, and PsbX1, was regulated differently between female and male hybrids by water deficit stress. Higher expression of SOD in moderate-water-deficit-treated females and higher GST, bHLH35 expression in both moderate- and severe-water-deficit-treated females suggest that the female sib is more sensitive, whilst higher expression of SOD in severe-water-deficit-treated males and higher PsbX1 expression in water-deficit-treated males testify that males protect cells better. To achieve an integrated view, all these variables were analyzed through the use of a principal component analysis and a total discrepancy between the sexes in their response to water deficit was demonstrated. The results indicate that, compared with male poplar sibs, females are more sensitive, but deploy a weaker protective apparatus to deal with water deficit.

“…Furthermore, resilience to drought, defined as the duration of tree recovery to pre-drought levels, was found to generally differ among conifer species [14]. For example, Scots pine (Pinus sylvestris) and white spruce (Picea glauca) tended to recover more rapidly from drought than green ash (Fraxinus pennsylvanica) [15]. Korean pine (Pinus koraiensis) has a low drought resistance but a high recovery capacity [16].…”

The occurrence, frequency, and severity of drought are accelerating due to global warming. Understanding the vulnerability of plantation forests to climate change, particularly to drought events, is critical to revealing the underlying mechanisms of tree resilience, recovery, and acclimation, which are important for plantation management. How the stand age affects the climate sensitivity of tree growth, as well as the direction, magnitude, and duration of the drought legacy, in plantation forests in northeast China is still unclear. In this study, we used MODIS-derived NDVI time series with gridded climate data from 2000 to 2020 to fill this knowledge gap. The selected plantation forests were dominated by four coniferous species: Korean pine (Pinus koraiensis), Scots pine (Pinus sylvestris), Japanese larch (Larix kaempferi), and Dahurian larch (Larix gmelinii). The results show that the climate sensitivity of tree growth differed among species and age groups. The growth of Korean pine and Scots pine was mostly dependent upon precipitation, while the growth of Japanese larch and Dahurian larch was determined primarily by temperature. Old Japanese larch (21–40 years) and Dahurian larch trees (31–60 years) were more sensitive to temperature and precipitation than young conspecifics, whereas old Korean pine (41–60 years) and Scots pine (31–60 years) were less sensitive to precipitation and temperature than young conspecifics. Furthermore, the legacy of drought lasted one year for Korean pine, Japanese larch, and Dahurian larch and over three years for Scots pine. Old trees were more severely affected by drought, particularly Scots pine and Dahurian larch. The findings of the study can help improve plantation forest management for better adaptation to future climate change.

“…Natural processes also influence local and global environments, with the changes measured and studied through various proxies, including ice cores, lake sediments, coral, and tree rings [4]. Dendrochronology has aided in understanding historical processes, both natural, such as climate reconstructions and future climate-based growth predictions in dendroclimatology, and through anthropogenic activities such as dating wooden structures in dendroarchaeology [5][6][7]. In the last 50 years, a new subdiscipline of dendrochronology has emerged, using the elemental concentrations within tree rings to create a timeline of changes to environmental chemistry, the subdiscipline of dendrochemistry [8].…”

Dendrochemistry, the study of elements found within tree rings, has been used to understand environmental changes from both natural and anthropogenic sources. When used appropriately, dendrochemistry can provide a greater understanding of the elemental changes in the environment. However, environmental and species-specific processes have been shown to impact results, and research from the field has been scrutinized due to the need for a greater understanding that role-specific processes such as translocation play. This systematic literature review examines dendrochemistry’s history, highlights how the field has changed, and hypothesizes where it might be headed. From this review, we recommend the following measures: (1) promoting the use of new experimental techniques and methods with faster data acquisition time to allow for a greater number of samples to be processed and included in studies to increase statistical significance; (2) that more studies focus on the two- and three-dimensional space that trees grow in and consider the complex physiological processes occurring in that space and over time and (3) more lab-based studies to reduce the variables that cannot be controlled when sampling in situ. Understanding the challenges and opportunities from the past, present, and future research of dendrochemistry is crucial to the advancement of the field.
