The municipal solid waste (MSW) landfill in Vientiane, Laos, which receives > 300 tons of daily, approximately 50% is organic matter, has caused serious environmental problems. This study was conducted to investigate the accumulated levels heavy metals (HMs) (cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), and zinc (Zn)) water (surface groundwater), soil, plants between dry wet seasons according standards Agreement on National Environmental Standards Laos (ANESs), Dutch...
Abstract Crop allelopathy may be useful to minimize serious problems in the present agricultural production such as environmental pollution, unsafe products, human health concerns, depletion of crop diversity, soil sickness and reduction productivity. Several crops including alfalfa, buckwheat, maize, rice, rye, sorghum, sunflower, wheat, etc. are affected either by their own toxicity or phytotoxin exudates when residues decompose soil, that show strong suppression on weed emergences....
Abstract In attempts to control weeds in rice, much effort has been focused on rice allelopathy research for more than 30 years. Among screening methods that have developed, some estimate the allelopathic potential of various cultivars a limited time and space, which is less costly can be conducted year round. Rice activity variety dependent origin dependent, where Japonica shows greater Indica Japonica–Indica hybrids. Allelopathic characteristics are quantitatively inherited several...
Bioactive compounds, which are naturally produced in plants, have been concerned with the food and pharmaceutical industries because of pharmacological effects on humans. In this study, individual phenolics six legumes during germination antioxidant capacity from sprout extracts were determined. It was found that phenolic content significantly increased all legumes. Peanuts showed strongest both DPPH• (1,1-diphenyl-2-picrylhydrazyl) method reducing power assay (32.51% 84.48%, respectively)....
In this study, responses of rice under drought stress correlating with changes in chemical compositions were examined. Among 20 studied cultivars, Q8 was the most tolerant, whereas Q2 susceptible to drought. Total phenols, total flavonoids, and antioxidant activities, their accumulation water deficit conditions proportional resistance levels rice. detail, phenols flavonoids (65.3 mg gallic acid equivalent (GAE) 37.8 rutin (RE) significantly higher than (33.9 GAE/g 27.4 RE/g, respectively)...
The riverine ecosystems of the Mekong River Basin possess world’s most productive inland fishery and provide highly food crops for millions people annually. development hydropower potential in has long been interest to governments region. Among existing 64 dams, 46 dams have built Lower (LMB) produce up 8650 MW electricity. Additionally, 123 proposed eleven plants nominated river mainstream are expected install a total 13,000 LMB countries. However, serious concerns intensified over negative...
Rice is a stable food in Vietnam and plays key role the economy of country. However, production cultivating areas are adversely affected from threats devastation caused by rise sea level. Using marker-assisted backcrossing (MABC) to develop new salt tolerance rice cultivar one feasible methods cope with these devastating changes. To improve BT7 cultivar, FL478 was used as donor parent introgress Saltol QTL conferring into BT7. Three backcrosses were conducted successfully transferred...
The fruits of Canarium tramdenum are commonly used as foods and cooking ingredients in Vietnam, Laos, the southeast region China, whilst leaves traditionally for treating diarrhea rheumatism. This study was conducted to investigate potential use this plant bark antioxidants, α-amylase α-glucosidase inhibitors. Five different extracts C. (TDB) consisting extract (TDBS) factional hexane (TDBH), ethyl acetate (TDBE), butanol (TDBB), water (TDBW) were evaluated. TDBS contained highest amount...
Nutrient management and fertilizer application are influential elements for high yield preferred grain quality. Negligible information is available regarding in the paddy fields Afghanistan. This research elucidates efficacy of different fertilizers’ on growth attributes, potential, quality rice. The treatments included traditional rate nitrogen phosphorus (RD), animal manure (AM), with 50% (AMRD), sawdust (SD), (SDRD). Growth parameters, its components, physicochemical properties,...
Celastrus hindsii is a popular medicinal plant in Vietnam and Southeast Asian countries as well South America. In this study, an amount of 12.05 g α-amyrin β-amyrin mixture was isolated from C. (10.75 g/kg dry weight) by column chromatography applying different solvent systems to obtain maximum efficiency. α-Amyrin were then confirmed gas chromatography-mass spectrometry (GC-MS), electrospray ionization-mass (ESI-MS), nuclear magnetic resonance (NMR). The antioxidant activities the...
This review paper examines acid and alkaline pretreatments on perennial grasses for second-generation (2G) bioethanol production, a relatively unexplored area in this field. It compares the efficiency of these producing fermentable sugar yield. study finds that pretreatment is more effective than acidic removing lignin increasing yield, leading to higher ethanol yields. However, it costlier requires longer reaction times pretreatment, while often leads formation inhibitory compounds at...
We evaluated total phenolic content, antioxidant activity, reducing power and antibacterial activity of ethanol, hexane, chloroform, ethyl acetate aqueous extracts aerial parts Rumex japonicus HOUTT. The extract had the highest amount compounds. It also exhibited when assayed by 1,1-diphenyl-2-picrylhydrazyl (DPPH), β-carotene bleaching superoxide radical methods. possessed strongest against Bacillus subtilis, B. cereus E. coli. GC-MS analysis indicated that contained a variety HPLC showed...
Increasing growth and productivity of food crops via safe biostimulants is a very important issue in the current years. This study aimed to investigate potential moringa leaf extract (MLE) improving performance snap bean (Phaseolus vulgaris L.) cv. 'Paulista' under field conditions. Hormonal analysis MLE revealed its richness various classes phytohormones particularly salicylates. The results that all concentrations had positive effect on growth, biochemical, yield, yield related traits as...
This study analyzed chemical components and investigated the antioxidant antimicrobial activities of fourteen vegetable edible oils marketed in Japan. High-performance liquid chromatography (HPLC) was used to identify quantify principal phenolic acids flavonoids. In 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging assay, sunflower, safflower, canola, soybean, Inca inchi, sesame, rice bran showed markedly greater activity, whilst percentage lipid peroxidation inhibition (LPI%) cotton,...
Tridax procumbens L. is a medicinal plant and used as drink to treat bronchial catarrh, diarrhea, dysentery liver diseases. In this study, we evaluated the potential use of T. hyperuricemia, oxidative stress, bacterial infection. Ethyl acetate extract was separated different fractions by column chromatography (CC) using chloroform methanol eluents subjected xanthine oxidase (XO) inhibitory, antioxidant, antibacterial assays. The results showed that F45⁻47 fraction exhibited strongest XO...
