screening methods that are effective in the early stage of growth will potentially provide the largest quantity of breeding material. although various screening methods under greenhouse have been proposed, potential effective approaches must be described a good correlation with results under field conditions. this study was aimed to assess the correlations between traits obtained from four salt...

Abstract: Ridge culture is a special conservation tillage method, but the long-term influence of this tillage system on soil aggregate-size stability in paddy fields is largely unknown in southwest of china. The objectives of this paper are to evaluate soil aggregates stability and to determine the relationship between SOC and soil aggregate stability.Soil samples at 0-20 cm layer were adopted ...

nitrogen forms exert significant effects on physiological and morphological characteristics of plant. in this study, the effects of ammonium, nitrate, and ammonium-nitrate on pepper plants were investigated in soil culture, as well as in solution culture. in the soil culture, 3, 4-dimethylpyrazole phosphate (dmpp) was used as a standard nitrification inhibitor to guarantee the presence of ammon...

bacterial culturability and abundance in an alpine soil. (manuscript) isolated from alpine and forest soils. Int. Dr. F. Gich has supervised the diploma-thesis from H. Hoffelner who has contributed the alpine soil sample, the data for the ATP activity in soil slurries, the data of the preliminary tests for detachment of soil bacteria from soil particles, and has produced the MicroDrop cultures....

In two independent experiments, acclimatized chicory plants were transferred into an aeroponic system and to the soil. Then, the effects of biofertilizer (Nitrokara) and culture filtrate of Piriformospora indica were investigated on some plant characteristics in both aeroponic and soil cultivation system under greenhouse conditions. The plants were foliar sprayed with three different biofertili...

Socio-economic and environmental impacts analysis of shrimp (Paeneus monodon) farming in the gher area of Bagerhat District is an important aspect where shrimp cultivation increased over the years. An investigation was conducted to evaluate the present socio-economic status as well as to investigate the soil and water quality of the study area. This study has been carried out at ten villages in...

BACKGROUND Culture is the gold standard for the detection of environmental B. pseudomallei. In general, soil specimens are cultured in enrichment broth for 2 days, and then the culture broth is streaked on an agar plate and incubated further for 7 days. However, identifying B. pseudomallei on the agar plates among other soil microbes requires expertise and experience. Here, we evaluate a latera...

The relationship between plant species coexistence and soil microbial communities under heavy metal pollution has attracted much attention in ecology. However, whether plant species coexistence could offset the impacts of heavy metal combined pollution on soil microbial community structure and soil enzymes activities is not well studied. The modified ecological dose model and PCR-RAPD method we...

The effect of different concentrations of the anionic surfactant sodium dodecyl sulfate (SDS) on biodegradation of diesel oil was assessed during 32 days at 10 degrees C, under simulated environmental conditions, in liquid culture and in an alpine soil. Low SDS concentrations (50-100 mg l-1) significantly enhanced oil biodegradation by a psychrotrophic inoculum in liquid culture, whereas higher...
