Magnetic water technology is supposed to be an eco-friendly tool used for alleviating drought stress in the agricultural sector. The present study investigates the role of magnetized water on the two Moringa species (Moringa oleifera and Moringa peregrina) under drought stress. The experiments were conducted in a greenhouse to compare three watering regimes, including, 100% field capacity (FC, as...
Three β-type genes coding for carbonic anhydrase and CA activities from Orychophragmus violaceus L. and Brassica juncea L. leaves in response to NaHCO₃ -induced bicarbonate stress were examined. Three full-length cDNA CDS sequences were designated as OvCA1, OvCA3, and OvCA4 in Orychophragmus violaceus, and as BjCA1, BjCA3, and BjCA4 in Brassica juncea; these genes encoding β-CAs were identified and...
Located northeast of Yuxi City, Yunnan Province, China, the Fuxian Lake Basin is not only a famous scenic area, but also an ecological and environmental protection zone. The basin is a plateau mountainous lake region that has key ecosystem vulnerability and sensitivity. A dynamic evaluation of ecological vulnerability is important for assessing the ecological environment of a region, which is significant...
To assess the effect of copper pollution meadow on grazing Wumeng semi-fine wool sheep and find an action plan to solve copper pollution, two experiments (grazing and sulfur supplementation) were conducted on copper pollution meadow at Wumeng mountainous area in Weining County of Guizhou Province. The contents of heavy metal elements were analyzed by inductively coupled plasma atomic emission spectroscopy...
Our study used a photocatalytic oxidation process for degrading slaughterhouse wastewater (SHWW). Characterization of the wastewater before and after treatment with TiO₂ and Ag-TiO₂ in terms of BOD, COD, and nitrogen was done. The effect of hydrogen peroxide, ozone, and various operating parameters such as catalyst dose, pH, and reaction time on the degradation efficiency of the process were also...
This paper reports the results of research aimed at assessing the recreational value (in the context of cultural value) of SCI Vtáčnik (central Slovakia), which is visited by about 16,000 tourists per year. The questionnaire survey was conducted from April to October 2015. The return rate of the questionnaire was 61.8% (309 respondents) out of 500 distributed copies consisting of 24 questions each...
Arsenic is a serious soil pollutant with toxic effects on biological systems. Elevated soil concentrations may negatively affect crop production and food safety. The impact of arsenic on plants depends on many factors, including nitrogen availability. Nitrogen (N) as an essential mineral affects overall energetics of plants, while its non-optimal doses have been shown to also impact plant performance...
Livestock animals are seriously contributing to global warming as methane producers. Six levels (0, 2, 4, 6, 8, and 10 ml.kg⁻¹ DM) of eucalyptus oil (EuO) were investigated under in vitro conditions to study the mitigation ability for methane production, using two rations: R1 (70% forage: 30% concentrates) and R2 (60% forage: 40% concentrates). Two cannulated sheep were used as donor animals to obtain...
The assessment of plant species’ introduction efficiencies for wet meadows was the aim of our study. The studies were carried out as part of a project focusing on flooded meadow restoration in the Middle Vistula Valley. Twenty-six plant species of flooded meadow were in the seedling material used for renovation. The seedbed preparation covered the cutting of vegetation, ploughing, and rototilling,...
Groundwater level rises rapidly when mine drainage systems stop functioning after mine closures. Free-form polycyclic aromatic hydrocarbons (PAHs) in residual pillaring and abandoned mining levels could continue to migrate because of eluviation leaching. Moreover, other aquifers are polluted with mine water through mining-induced fractures, faults, and poorly sealed drill holes. Therefore, the distributions...
Determining the influence of a sublethal concentration of the organophosphate pesticide profenofos on the proximate composition of muscle in Catla catla, Labeo rohita, and Cirrhinus mrigala was the aim of this study. Three sublethal concentrations of profenofos were given to the fish in three replicates for eight weeks. Moisture content exhibited a rapid increase in C. catla, L. rohita, and C. mrigala,...
The response of leaf functional traits to the shift in environmental variables can raise plant adaptiveness in a wide variety of habitats and subsequently broaden their ecological niche. This study aims to determine the differences in leaf functional traits between simple and compound leaves of Canavalia maritime to illuminate the mechanisms underlying the ecological strategy of plant species with...
Indoor experiments were performed to determine the accumulation, subcellular distribution, and chemical forms of Cd at five S levels in Hydrilla verticillata. The Cd content increased from 1.229 mg/g to 3.329 mg/g in leaves, and decreased from 2.794 mg/g to 1.023 mg/g in roots, respectively. Excess S supply stimulated Cd assimilation in leaves as Cd accumulation was inhibited in roots. The Cd content...
In this paper, we assess the effect of ecological construction in China during 2008 to 2014. The effect of ecological construction is divided into green economy, green society, and green environment. A network data envelopment analysis (DEA) is employed to measure the total level of ecological construction in China and each region. According to the results, we find that the total level of ecological...
Variation laws of growth conditions and root cortical aerenchyma (RCA) of 15 common maize hybrids (Zea mays L.) in Yunnan Province under simulated rare extreme drought and rehydration conditions were tested in this paper. The relationship between functions of root tissues in extreme drought process and resilience after rehydration was discussed. Results demonstrated: 1) in middle drought period, RCA...
Modern techniques such as microwave treatment as clean and uniform treatment in textile processing have been used to make the dyeing process eco-friendly, plus time and cost effective. The present study is concerned with the effect of microwave irradiation on dyeing of cotton fabric using Reactive Blue 21 dye. Irradiated (RC) and un-irradiated cotton fabrics (NRC) were dyed using irradiated (RS) and...
The application of nitrogen fertilizers can improve the soil environment and influence the nutrition and quality of plants; there are also significant impacts of soil types on soil microbial communities. Research on the coupling effects between the rates of nitrogen fertilizer and the soil types on soil microbial metabolic activities under field conditions are currently lacking. In this study, we...
Precipitation is an important element in the hydrological cycle in mountainous regions. Temporal and spatial variations in precipitation and in its two phases – rain and snow – over the northern and southern aspects of the slopes of the Tianshan Mountains are compared and analyzed using 55-year data (1961-2015). The results of the analysis are as follows: 1) The average annual precipitation shows...
Constructed wetlands have been extensively applied for treating drinking water sources and other water bodies that are not severely polluted due to their low construction and operation costs. In this regard, microbial fuel cells (MFC) could potentially achieve both energy generation and wastewater purification, though the construction cost is high. Based on the bio-electrochemical theory, a novel...
Iron sulphate and polyaluminum chloride are commonly used in water restoration to eliminate cyanobacteria bloom and improve water quality. Nevertheless, the influence of coagulants on water organisms remains insufficiently studied. The study involves the analysis of phosphate coagulants’ impact on calcium and magnesium concentrations in the Chara hispida community. The experiments were carried out...
