The aboveground organs of plants are natural bioindicators atmospheric precipitation, and their study makes it possible to assess the state geochemical background a number elements, including mercury. Mercury is highly toxic element for all living organisms. mercury content was determined on RA-915M analyzer with PIRO attachment Regional shared services center Cherepovets State University. data...

Forest ecosystems are among the largest terrestrial carbon reservoirs on our planet earth thus playing a vital role in global carbon cycle. Presently, remote sensing techniques provide proper estimates of forest biomass and quantify carbon stocks. The present study has explored Landsat-8 sensor product and evaluated its application in biomass mapping and estimation. The specific objectives were...

Two-year-old seedlings of T. cordata and P. pyraster were exposed to salinity for 50 days, whereby each plant was subject regular applications a substrate solution containing 100 mM NaCl, amounting cumulative volume 365 mL per plant. The adaptive reactions the tree species in coping with salt stress studied. measured parameters growth distribution mass organs, root shoot ratio (R:S), content as...

Introduction. Golden dock ( Rumex maritimus L., Polygonaceae ) is used as a medicinal and food plant in Asian countries. The contains phytochemicals of various classes: flavonoids, tannins, anthraquinones etc. Plant extracts exhibit antibacterial, antioxidant, anti-inflammatory, astringent activity, have antidiabetic potential. annual, most the biologically active substances accumulate its abov...

Based on 10 years of environmental monitoring located around the emission zone an electricity supplier, main regularities have been studied for content heavy metals (HMs), such as Pb, Cd, Zn, Cu, Ni, Mn, and Cr, 16 priority polycyclic aromatic hydrocarbons (PAHs) in soils agricultural landscapes their accumulation Triticum aestivum. It has shown that one most significant factors pollutants plan...

The objects of study were coniferous plants aged from 6 to 10 years. involved such as Siberian spruce (Pícea obováta), prickly Hoopsi (Picea pungens Hoopsii), western thuja Smaragd (Thuja occidentalis Smaragd), Brabant Brabant). subject the was pathological symptoms manifested on aboveground plant organs. planted in 2015 at age (thuja and Brabant) (prickly spruce) studies conducted May 2016 Sep...

Studying changes in partitioning of dry matter and nonstructural carbohydrates (NSC) content both aboveground underground perennial tissues drought-affected grapevines could provide insights into plant response carbon allocation strategies during stress periods. The analysis soluble NSC starch leaf petioles, due to their role hydraulic segmentation, should also be considered. In the present res...

Soil pollution by trace elements (TEs) from mining and industrial activity is widespread and presents a risk to humans and ecosystems. The use of trees to immobilize TEs (phytostabilization) is a low-cost and effective method of soil remediation. We aimed to determine the chemical composition of leaves and flower buds of Eucalyptus camaldulensis in seven sites along the Guadiamar River valley (...

This paper presents an analysis of the morphological and anatomical characteristics aboveground parts (herba) clary sage (Salvia sclarea L.), with emphasis on investigation its surface structures. After procedure primary processing drying plant material, it was determined that composition crushed herbal drug Salviae sclareae herba showed presence leaves, bracts, flowers axis inflorescence, stem...

This study investigated spatial patterns and environmental controls of aboveground biomass (AGB) in alpine grasslands on the Tibetan Plateau by integrating AGB data collected from 135 sites during 2001– 2004 and concurrent enhanced vegetation index derived from MODIS data sets. The AGB was estimated at 68.8 gm 2, with a larger value (90.8 gm 2) in alpine meadow than in alpine steppe (50.1 gm 2)...
