World-wide, forests are experiencing drought-induced mortality. However, physiological adaptation to drought is highly variable, which may lead to differential mortality patterns and alter community structure. In this study, saplings of four common tree species (Ormosia pinnata, Dalbergia odorifera...

The survival and performance of urban forests are increasingly challenged by urban drought, consequently compromising the sustainability and functionality of urban vegetation. Plant-water relations largely determine species drought tolerance, yet little is known about the hydraulics of urban forest ...

Eastern Australia was subject to its hottest and driest year on record in 2019. This extreme drought resulted in massive canopy die-back in eucalypt forests. The role of hydraulic failure and tree size on canopy die-back in three eucalypt tree species during this drought was examined. We measured...

In order to study the mechanism of drought-resistance in Tamarix leptostachys Bunge, this paper took the seedlings of Tamarix leptostachys Bunge with 2 a panicles as materials, and measured the growth and physiological traits of Tamarix leptostachys Bunge seedlings under different drought stresses. ...

Catastrophic failure of the water transport pathway in trees is a principal mechanism of mortality during extreme drought. To be able to predict the probability of mortality at an individual and landscape scale we need knowledge of the time for plants to reach critical levels of hydraulic failure....

Irrigation is essential for sustaining the productivity of plantation forests in arid, semi-arid, and seasonal drought regions. Current irrigation management is commonly scheduled based on time or soil water status, which often fails to capture plant physiological demand. Here we report on the...

The Ginkgo (Ginkgo biloba L.) is a nonconiferous gymnosperm tree species and an enigmatic living fossil that has recently been globally redistributed. In this study, we conducted a drought-rehydration experiment to examine the physiological responses of ginkgo saplings. We aimed to integrate...

Three new xanthone compounds, 1,3,5-trihydroxy-2-(2-hydroxy-3-methylbut-3-enyl)-4-(3-methylbut-2-enyl)xanthone (1), toxyloxanthone E (2), dehydrocycloguanandin B (3) along with 15 known xanthones (4-18) were isolated from the aerial parts of Calophyllum polyanthum Wall. ex Choisy. Their structures...

Quantifying tree water use and its environmental controlling mechanisms are significantly important for understanding of adaptation strategy of trees and plantation management in semiarid and arid regions. Here, tree water consumption and tree conductance of Chinese pine (Pinus tabuliformis)...

The Ethylene Responsive Factor (ERF) transcription factor family is important for regulating plant growth and stress responses. Although the expression patterns of ERF family members have been reported in many plant species, their role in Populus alba × Populus glandulosa, an important model plant...
