Laboratory experiments of vacuum treatment in combination with an O2 absorber for the suppression of Sitophilus granarius infestations in stored grain samples
The effectiveness of vacuum (V) treatment alone and in combination with an oxygen absorber (V + A) for suppression of grain infestation by Sitophilus granarius L. were compared under laboratory conditions. The effectiveness of the treatment methods was evaluated at different temperatures (15, 25 °C) and exposure times (7, 14, 21, 28 days). We evaluated both the effects on adults present in ...


Assessment of the climate-change impacts and evaluation of adaptation measures for paddy productivity in Quang Nam province, Vietnam
This study investigates the impacts of climate change on winter and summer paddy yields and evaluates adaptation measures in order to overcome the projected impacts of climate change in Quang Nam province of Vietnam. Future climate-change scenarios for the periods of 2020s, 2050s and 2080s were projected by downscaling the outputs of HadCM3 general circulation model for the two selected IPCC SR...
Mechanical properties and water purification characteristics of natural jute fiber-reinforced non-cement alkali-activated porous vegetation blocks
This study reports the effects of the volume fraction of natural jute fiber and the content of the alkali activator on the physical and mechanical properties, sulfate ion resistance, and water purification characteristics of non-cement porous vegetation blocks. The volume fractions of the natural jute fiber were 0.0, 0.1, and 0.2 %, and the alkali activator was applied by replacing 5, 6, 7, 8,...


Quantitative trait loci for resistance to Maize rayado fino virus
Maize rayado fino virus (MRFV) causes one of the most important virus diseases of maize in regions of Mexico, Central and South America, where it causes moderate to severe yield losses. The virus is found from the southern USA to northern Argentina where its vector, the maize leafhopper Dalbulus maidis, is present. Although resistance to MRFV has been identified in tropical maize lines, little ...
A novel soil wetting technique for measuring wet stable aggregates
The measurement of aggregate size distribution and stability has been widely used to evaluate soil quality, yet there exists large variation in measured values from various pre-wetting methods. The most widely used technique, the high vacuum slow wetting (HVSW) method, could minimize the variability in wet aggregate stability (WAS) of samples, but is laborious and time consuming. In this paper,...


Removal of heavy metal ions from aqueous medium using Kuluncak (Malatya) vermiculites and effect of precipitation on removal
The removal of heavy metal ions, Cr3+, Pb2+ and Zn2+, by vermiculite was studied by batch adsorption tests. Influence of experimental parameters (e.g., medium pH and initial ion concentration) on removal was examined separately. Metal hydroxide formation in the dispersions and their precipitation was also investigated to assess the effect of precipitation on ion removal. For this purpose, some ...
Effect of coconut water and growth regulator supplements on in vitro propagation of Corylus avellana L
Corylus avellana L. represents an economically important crop in the European Union. Several protocols of hazelnut micropropagation have been tested but have not yet provided effective methods to allow large-scale propagation for commercial purposes, due to poor proliferation and yield. The aim of this work was to study the in vitro effects of coconut water (CW) in combinations with gibberellin...

Nitric oxide reduces pericarp browning and preserves bioactive antioxidants in litchi
Pericarp browning is the most important postharvest problem in litchi (Litchi chinensis Sonn.), which reduces the commercial acceptability and shelf life of fruit. In the present study, effect of nitric oxide (NO) on pericarp browning, bioactive antioxidants, and shelf life of fruit was investigated. Fruits were treated with the NO donor, sodium nitroprusside (SNP; 0.5mM, 1.0mM or 2.0mM) by the...
Distinct expression profiles of ripening related genes in the ‘Nanguo’ pear (Pyrus ussuriensis) fruits
‘Nanguo’ pear (Pyrus ussuriensis) is one of the most important pear varieties in the northern part of China. It is typical climacteric fruit, and the ripening process is controlled by ethylene. In this study, we compared the fruit firmness and ethylene production between non-treated fruits and fruits treated with 1μll−1 of 1-MCP (1-Methylcyclopropene, an ethylene inhibitor) under 4°C or...

High and low root zone temperatures at bud-break reduce growth and influence dry matter partitioning in peach rootstocks
Previous studies with actively growing peach [Prunus persica (L.) Batsch] rootstocks have shown that low root zone temperatures (RZTs) affect growth and partitioning of dry mass. However, whether plants show similar responses at other phenological stages has not been examined, nor has the influence of high RZTs. Consequently, we examined the effects of high and low RZTs on dry matter accumulati...
Antifungal activity of asparagus extracts against phytopathogenic Fusarium oxysporum
Asparagus, carnation and strawberry are major horticultural crops in southern Spain, where diseases caused by soilborne pathogens are frequent. Among them, Fusarium spp. are the fungi more frequently associated to the infection of underground plant organs. Flavonoids are phenolic compounds which possess a wide range of biological activities, including antifungal activity. In this work we evalua...

Analysis of spatial and temporal patterns in onset, cessation and length of growing season in Nigeria
Proper understanding of patterns, distribution and changes in rainfall onset dates (ROD), rainfall cessation dates (RCD) and lengths of growing seasons (LGS) is crucial for agricultural planning, adaptation strategies and food security in Nigeria. This study determines the spatial and temporal changes and examines the relationships among these rainfall attributes in addition to possible synopti...
Combined stationarity index for the estimation of turbulent fluxes of scalars and particles in the atmospheric surface layer
In this work the performances of three different tests widely used in scientific community for assessing turbulent flow stationarity have been tested and compared. The stationarity tests have been applied to turbulent fluxes of different scalars (temperature, carbon dioxide and water vapour concentration, ultrafine particle number concentration), collected over a wide range of surface roughness...
Implications of sensor configuration and topography on vertical plant profiles derived from terrestrial LiDAR
The vertical distribution of plant constituents is a key parameter to describe vegetation structure and influences several processes, such as radiation interception, growth and habitat. Terrestrial laser scanning (TLS), also referred to as terrestrial LiDAR, has the potential to measure the canopy structure with high spatial detail and accuracy. Vertical plant profiles, which describe the plant...
Yield-scaled greenhouse gas emissions from flood irrigated rice under long-term conventional tillage and no-till systems in a Humid Subtropical climate
Soils under flooded rice (Oryza sativa L.) production are one of the major anthropogenic source of CH4 emissions, an important greenhouse gas (GHG) with a 25-times larger global warming potential (GWP) than CO2. No-till systems (NT) systems may be a viable alternative to mitigate GHG emissions in comparison to conventional tillage (CT). The objectives of this study were to evaluate on a field s...
