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 ...

Molecular networking (MN) is an efficient tool for natural product research. However, single MN might lead to false annotation due to the limited information, and the importance of combining MN with chromatogram is always ignored. In this study, we proposed a comprehensive MN strategy combining...

Trees growing on paved lands endure many environmental stresses in the urban environment. However, the morphological and physiological mechanisms underlying tree adaptation to pavement in the field are less known. In this study, we investigated 40 sites where Ginkgo biloba and Platanus orientalis...

Ginkgo biloba, the main greening tree species in Beijing, was used to study the effects of elevated ozone (O₃) concentrations on physiology and ecology using an open-top air chamber (OTC). We set three O₃ concentration gradients (NF: normal atmospheric O₃ concentration; NF40: normal atmospheric O₃...

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...

To elucidate the physiological and transcriptomic regulatory mechanisms underlying flavonoid concentrations in ginkgo leaves in response to full and partial root-zone drying, double-rootstock grafted ginkgo saplings that could split roots easily were exposed to one of three water treatments:...

Plant-derived diterpenoids are commonly used as conifer-specific biomarkers and for chemotaxonomic assignment or confirmation. Numerous studies have reported on the utility of diterpenoids as chemotaxonomic indicators, but few have quantitatively analyzed diterpenoid concentrations, especially with ...

In this experiment, two-factor 7-level uniform design scheme was applied. Separate treatment of each factor was performed for single effect test. Then, it analyzed the effects of acid and aluminum stress under soilless culture on the water content of plant during the growth of Ginkgo biloba L....

Ginkgo (Ginkgo biloba) as a precious relict plant is cultivated around the world, and it is also a typical dioecious tree. Drought is a major environmental stress that limits the growth and development of ginkgo. Although many studies have examined the impact of drought on ginkgo, few have...

We conducted on-site studies in Kyoto City, Japan, to evaluate the effect of air pollution by automobile gas exhaust on the leaf photosynthetic functions of four urban roadside tree species. Nitrogen oxides (NO and NO₂) are major air pollutants that are related to automobile gas exhaust. The...
