本文研究了‘红港’桃和西沙樱桃(Prunus besseyi Bailey)营养系‘CG8—24’不同无花期与需冷量和休眠后热量累积间的关素。从田间采集枝条经人工低温处理及温室促培证明,两个营养系的花芽需冷量是相似的。人工低温处理树,在休眠后不同温度条件下的促培,揭示了红港桃花芽热量积累的起点温度为4.3℃,‘CG3—24’樱桃的花芽发育的Q10值,分别为2.2和2.8。这些结果表明,不同开花期是由于热量积累的起点温度不同所引起,而与需冷量无关。

Subtle Variations in Surface Properties of Black Silicon Surfaces Influence the Degree of Bactericidal Efficiency

One of the maj.r challenges faced by the biomedical industry is the development of robust synthetic surfaces that can resist bacterial colonization. Much inspiration has been drawn recently from naturally occurring mechano-bactericidal surfaces such as the wings of cicada(Psaltoda claripennis) and dragonfly(Diplacodes bipunctata) species in fabricating their synthetic analogs. However,the bactericidal activity of nanostructured surfaces is observed in a particular range of parameters reflecting the geometry of nanostructures and surface wettability. Here,several of the nanometer-scale characteristics of black silicon(bSi) surfaces including the density and height of the nanopillars that have the potential to influence the bactericidal efficiency of these nanostructured surfaces have been investigated. The results provide important evidence that minor variations in the nanoarchitecture of substrata can substantially alter their performance as bactericidal surfaces.

Organic carbon dynamics and enzyme activities in agricultural soils amended with biogas slurry, liquid manure and sewage sludge

引用

Agricultural Sciences 2012年第1期3卷 104-113页

作者： Britta Stumpe Steffen werner Robert j.ng Stefanie Heinze Elisabeth j.schke Christian Strippel Bernd Marschner Department Soil Science/Soil Ecology Institute of Geography Ruhr-University Bochum Bochum Germany

The application of organic soil amendments is a common practice for increasing soil fertility and soil organic carbon (SOC) content. In recent years, a new product from biogas production, biogas slurry is increasingly applied to agricultural soils, although little is known about its effects on soil properties. In this study, the influence of this new product in comparison with liquid manure and sewage sludge on the organic carbon dynamics and enzyme activities were investigated in two different agricultural soils in short-term incubation studies. As a control, biologically inert sand was also amended with these organic wastes. In sand, biogas slurry degraded to 10.4% within 14 days, while no differences were found between the degradability of liquid manure and sewage sludge with 6.6% and 5.4%, respectively. However, although the degradability of biogas slurry was highest among the organic amendments, liquid manure application resulted in the highest respiration rates in the soil samples. This was likely due to the organic waste borne easily decomposable substrates which were most dominant in liquid manure. Organic waste applications were found to generally increase the activity of numerous enzymes but did not change the soil enzyme patterns. Thus, in general it was shown that the microbial population of the organic wastes will not become prominent when introduced with the manures to soils. Thus, an inoculation with organic waste borne microorganisms could likely be neglected when discussing the extent of organic carbon dynamics after organic waste application to agricultural soils.

Standardized high-throughput biomonitoring using DNA metabarcoding: Strategies for the adoption of automated liquid handlers

引用

Environmental Science and Ecotechnology 2021年第4期8卷 22-30页

作者： Dominik Buchner Till-Hendrik Macher Arne j.Beermann Marie-Therese werner Florian Leese University of Duisburg-Essen Aquatic Ecosystem ResearchUniversitatsstr.545141EssenGermany University of Duisburg-Essen Centre for Water and Environmental Research(ZWU)Universitatsstr.345141EssenGermany

Reliable and comprehensive monitoring data are required to trace and counteract biodiversity loss. Highthroughput metabarcoding using DNA extracted from community samples (bulk) or from water orsediment (environmental DNA) has revolutionized biomonitoring, given the capability to assess biodiversity across the tree of life rapidly with feasible effort and at a modest price. DNA metabarcoding canbe upscaled to process hundreds of samples in parallel. However, while automated high-throughputanalysis workflows are well-established in the medical sector, manual sample processing still predominates in biomonitoring laboratory workflows limiting the upscaling and standardization for routinemonitoring applications. Here we present an automated, scalable, and reproducible metabarcodingworkflow to extract DNA from bulk samples, perform PCR and library preparation on a liquid *** features are the independent sample replication throughout the workflow and the use of manynegative controls for quality assurance and quality control. We generated two datasets: i) a validationdataset consisting of 42 individual arthropod specimens of different species, and ii) a routine monitoringdataset consisting of 60 stream macroinvertebrate bulk samples. As a marker, we used the mitochondrialCOI gene. Our results show that the developed single-deck workflow is free of laboratory-derivedcontamination and produces highly consistent results. Minor deviations between replicates are mostlydue to stochastic differences for low abundant OTUs. Thus, we successfully demonstrated that roboticliquid handling can be used reliably from DNA extraction to final library preparation on a single deck,thereby substantially increasing throughput, reducing costs, and increasing data robustness for biodiversity assessments and monitoring.
