Introduction to Poplar Leaves

In this study, the chemical components of five foliage types (pine needles, black locust tree leaves, bamboo leaves, elm leaves and poplar leaves) were analyzed, including cellulose content, hemicellulose content, and lignin content.

Results showed attenuation of Cd phytotoxicity effects on cell organelles upon AMF inoculation, which also reduced the Cd concentration in the poplar leaves, stems, and roots.

The antioxidant and xanthine oxidase inhibition properties of extracts from poplar leaves were investigated by TLC bioautography.

Lichens and poplar leaves are used as indicators of environmental contamination, particularly atmospheric pollution; liquid precipitation is used as an indicator showing the negative impact of air pollution on ecosystems; hair is used as an indicator of the total body intake of chemical elements.

</p><p>We studied the influence of anecic earthworms (<em>Lumbricus terrestris</em> fed on poplar leaves) on the spatial and temporal variability in water outflow and storage through a soil column.

In 2017 high Hg concentration (1300 ng/g) in the poplar leaves was recorded in the northeastern part of the city near the industrial facility of the lithium plant.

Poplar leaves, like other C3 photosynthesis plants, have evolved oscillating or circadian rhythms that play important roles in synchronizing biological processes with external cues.

Poplar leaves are of interest as a new promising type of medicinal plant raw material, since they have a chemical composition close to the buds, moreover, they are much easier to harvest and the possible volume of raw materials procurement is much larger.

In this study, the effects of plant litter crust (plant litter from poplar leaves of the surrounding area and sand grains bonded together due to interaction of water erosion and wind erosion) on surface soil properties and the loamification process of sandy soil were assessed in a semi-arid sandy land ecosystem at the edge of Mu Us sandy land by the field experiment sampling and indoor analysis.

Poplar leaves (Populus L.

However, no significant difference was detected in the foliar chlorophyll content and glutamine synthetase activity of poplar under RD and RS treatment; only the nitrate reductase activity in poplar leaves under RD treatment declined significantly, by 22.

Reaction of poplar leaves on influence of hydrogen fluoride (HF) was investigated by ionometric technique, scanning electron microscopy-related method (SEM–EDS), X-ray diffraction analysis (XRD), and the thermodynamic modelling.

The overexpression of PeuGAT3 increased the thickness of xylem cells walls in both Arabidopsis and poplar and enhanced the lignin content of xylem tissues and the proline accumulation in poplar leaves, all of which may improve tolerance of salt/drought stress in desert poplars.

Moreover, the impacts of elevated O3 on phytochemistry of poplar leaves can be context-dependent, with potential consequences for ecosystem processes under future global change scenarios.

Atmospheric emissions from thermal power and metallurgical plants, and leather factory resulted in the accumulation of Zn, As, Cd, Cu, and Ni in the soils and poplar leaves.

Furthermore, the carbon catalysts derived from the petioles and blades of poplar leaves and parasol tree leaves show the same difference in catalytic reaction, implying that the above-mentioned conclusion is rather universal, which can provide reference for the synthesis of carbon materials from leaves.

In addition, TDIF-overexpression unexpectedly induced a more complex venation pattern in poplar leaves, which was underpinned by the elevated expression of WOX4 and WOX13 genes.

Notwithstanding the stable conditions of almost all hydrological and physico-chemical parameters, we found significant temporal differences in (i) % of mass loss of poplar leaves (ii) number of Ephemeroptera, Plecoptera and Trichoptera taxa, (iii) shredder and predator densities.

Nitrogen availability alter acclimation strategy of poplar leaves under cadmium exposure.

Three scores were attributed to each neighborhood according to a cumulative calculation of key parameters: environmental score (using 3 air biomonitoring parameters: trace elements loads in lichens, lichenic biodiversity and dust deposition on poplar leaves), socioeconomic deprivation score and susceptible population score.

Most importantly, the induced accumulation of MsrA2 peptide in poplar leaves was sufficient to confer resistance against S.
