The increase in nitrogen (N) deposition is expected to have strong influences on forest ecosystems through its direct and indirect effects on tree performance. One way that N deposition can greatly affect tree performance is by altering plant hydraulic architecture and water relations especially in ...

Dehydrins are well-known components of plant responses to different stresses that cause dehydration, including drought, freezing, salinity, etc. In conifers, the dehydrin gene family is very large, implying that the members of this family have important physiological functions in conifer stress...

The ratio of the primary mechanisms of carbon deposition in Scots pine (Pinus sylvestris L.) during the growing season was investigated. Temperature regulation of trunk respiratory expenditure and correlation of crown photosynthesis with trunk respiratory activity in spring and autumn have been...

Transpiration mediated by physiology is driven by the meteorological variables. Understanding their relationships is crucial to advancing terrestrial ecohydrological studies. Here, we used sap flow measurements in Scots pine to examine the temporal responses of transpiration to temperature (Ta),...

Objective The aim is to understand the difficulty of seedling breeding and to solve the natrual regeneration problem in declined stands of Pinus sylvestris var. mongolica sandy-fixation plantation, response characteristics of the seed germination and seedling growth as well as resistance to drought ...

Alternative water uptake pathways through leaves and bark complement water supply with interception, fog or dew. Bark water-uptake contributes to embolism-repair, as demonstrated in cut branches. We tested whether bark water-uptake could also contribute to supplement xylem-water for transpiration....

Delayed or incomplete recovery of gas exchange after water stress relief limits assimilation in the post-drought period and can thus negatively affect the processes of post-drought recovery. Abscisic acid (ABA) accumulation and antagonistic action between ABA and cytokinins (CKs) play an important...

Harsh environmental conditions affect both leaf structure and root traits. However, shoot growth in high-latitude systems is predominately under photoperiod control while root growth may occur for as long as thermal conditions are favorable. The different sensitivities of these organs may alter...

Physiological processes cause movements of tree stems and branches that occur in a circadian rhythm and over longer time periods, but there is a lack of quantitative understanding of the cause-and-effect relationships. We investigated the movement of tree branches in a long-term drought experiment...

Understanding the water use pattern and transpiration rate of revegetation species is crucial for efficient water management and sustainable vegetation restoration. Mongolian pine (P. sylvestris) plantation has been implemented for decades in desert regions of northwest China, achieving significant ...
