Využití magnetických částic pro izolaci DNA z vybraných druhů koření / The use of magnetic particles for DNA isolation from selected spices

Gaňová, Martina January 2017 (has links)
The isolation of DNA from plant tissue of the required quality is very complicated, especially because of the presence of substances that can interfere during amplification of DNA. These substances are mainly polyphenols, polysaccharides, proteins and various dyes. The chemical diversity of such materials can have a significant effect on the yield and quality of DNA using one isolation procedure. The main aim of the work was to evaluate the use of microisolation protocol for related matrices to the quality of the isolated DNA as well as the evaluation of the effect of inhibitors isolated with the nucleic acid to the amplification in the PCR. DNA was isolated from dried paprika (Capsicum annuum). In the first step, the samples were homogenized using a lysis reagent with cetyltrimethylammonium bromide. Subsequently, the DNA was purified by reversible adsorption on magnetic particles. It was tested six different modified particles. The concentration and purity of the obtained DNA was determined by spectrophotometry measuring the absorbance of the DNA solution in TE buffer. The quality of the DNA was confirmed by amplification in PCR. For the PCR were used primers specific for plant ribosomal DNA (rDNA). The presence of PCR products was detected by agarose gel electrophoresis. It was found out that used microassay is suitable for isolating of the DNA of the corresponding purity that is suitable for the genetic analysis by PCR. The differences were found between the magnetic particles that were tested for DNA isolation.

Factores que influyen en la exportación de Paprika seca (090421.10.90) respecto a la relación comercial entre Perú – México durante el periodo del 2008 - 2018

Pérez Segovia, Jesús Alejandro, Villafuerte Zamora, Ruth Briggitte 04 July 2019 (has links)
El presente estudio de investigación se basa en el análisis de tres variables que influyen en la exportación de paprika seca proveniente de Perú hacia el mercado de México durante el periodo 2008 al 2018. En ese sentido, se consideró necesario analizar las cuotas arancelarias, debido al alto grado de aplicación por parte de México para la importación de paprika seca desde la vigencia del Acuerdo de Integración Comercial en el año 2012. Por otra parte, otra variable que se consideró dentro de la investigación fueron las medidas sanitarias y fitosanitarias, ya que muchas veces estas suelen ejercer como una desviación hacia el comercio, sobre todo en productos agrícolas. Así mismo, como última variable se tuvo en consideración la competencia internacional. Dicha variable fue analizada con el apoyo de entrevistas y la realización de estadística que permitió ver la correlación directa entre los competidores y las exportaciones. Para el análisis de estas variables fue necesario un enfoque mixto, el cual se basó en un análisis estadístico de las exportaciones antes y después de la vigencia del AIC y de la competencia internacional. Además, también se usó las entrevistas especializadas para el estudio de la influencia de las medidas sanitarias y fitosanitarias para las exportaciones de paprika. En cuanto a los resultados, se pudo obtener que la variable más influyente fue la competencia internacional, las medidas sanitarias y fitosanitarias, y en menor medida las cuotas arancelarias de importación. / This research study is based on the analysis of three variables that influence the export of dried paprika from Peru to the Mexican market during the period 2008 to 2018. In that sense, it was considered necessary to analyze the tariff rate quotas, due to the high degree of application by Mexico for the importation of dried paprika since the Trade Integration Agreement entered into force in 2012. On the other hand, another variable that was considered within the investigation was the sanitary and phytosanitary measures, since often these tend to exert as a deviation towards trade, especially in agricultural products. Likewise, international competition was taken into account as the last variable. This variable was analyzed with the support of interviews and the realization of statistics that allowed seeing the direct correlation between competitors and exports. For the analysis of these variables, a mixed approach was necessary, which was based on a statistical analysis of exports before and after the validity of the AIC and international competition. In addition, specialized interviews were also used to study the influence of sanitary and phytosanitary measures for paprika exports. As for the results, it was possible to obtain that the most influential variable was international competition, sanitary and phytosanitary measures and, to a lesser extent, import tariff rate quotas. / Tesis

Využití antistresové látky pro minimalizaci dopadu stresorů na produkci zahradních plodin / Use of anti-stress agents to minimize the consequences of stressors on the production of Horticultural Crops

Nosálková, Monika January 2016 (has links)
The objective of the thesis is to research the physiological differences between picked genotypes of Capsicum annuum and the effect of lower temperatures in the beginning of ontogeny. Another objective is to find out how Capsicum annuum plants react to application of anti-stress agent Atonic and to determine the most appropriate physiological indicators of resistence to low temperatures. Capsicum annuum ranks among thermophilic crops for which the temperature optimum is of 22 - 25 °C during the day and 18 - 20 °C overnight. They are planted at the field station at the time when ground frost may occur. These can cause physiological changes in the plant or even cause her death. Three varieties were chosen for the experiment: Amy, Eva a Lydia. Plants were divided into a control group and treatment group. Both groups were further divided into two additional groups - with and without the application of Atonic in the beginning of vegetative growth (6th day of exposure to stress). Control group plants were grown at 20 °C and stressed plants were moved into a klimabox with temperature of 5 °C throughout the entire day. Such temperature may occur after planting the plants into an outdoor habitat. Proline content in leaves of Capsicum annuum and relative discharge of electrolyte was studied in two - day intervals. From the obtained results it can be concluded that the accumulation of proline was the highest for Lydia variety in a stressed scenario with the application of Atonic and the lowest proline content was found in in the Amy variety in a control group. Furthermore, it was discovered that the ontogeny of plants has an effect on the accumulation of proline and relative discharge of electrolyte from the beginning of the measurement. The absolute highest electrolyte discharge was measured in the Lydia variety in a stressed scenario and the lowest one was present in the Amy variety in a control group. These results confirm the hypothesis.

Vikten av klimat- och miljövänliga egenskaper för trallvirke : En conjointanalys om en miljövänlig trämodifiering utifrån ett kundperspektiv

Blomberg, Joakim, Edenström, Ludvig January 2022 (has links)
Development is currently being driven towards products that are linked to sustainability. Products with a positive imprint in sustainability are becoming increasingly valuable to consumers, which in turn creates increased value for producers and suppliers. The current pricing tools do not have room to consider the value of the sustainable properties of new products. This is something that the wood industry is following and is now facing the challenge of estimating the value of sustainable production. The study aims to estimate a value for environmentally/climate-friendly products in the wood industry from a customer perspective. This has been done by performing a conjoint analysis using PAPRIKA (Potentially All Pairwise Rankings of all possible Alternatives), to determine the relative importance of 6 product properties. The results of the study show that price is the most important property of wooden floor decking. The mean weight of the 6 attributes included in the study is; price (25,0%), aging (21,9%), maintenance intervals (16,9%), climate impact (16,9%), dimensional stability (10,2%) and biocides (9,1%). The conclusion of the results is if the purpose is to cover the majority of consumers, several different products with different properties should be produced. The results also indicate that the weight for sustainability attributes can increase if the consumer becomes more informed and gains a broader knowledge of the meaning of the properties. / Utvecklingen drivs just nu mot produkter som anknyts till hållbarhet. Produkter med ett positivt avtryck inom hållbarhet blir allt mer värdefull för konsumenten vilket i sin tur skapar ett ökat värde för producenter och leverantörer. De nuvarande verktygen för prissättning har inte utrymme att överväga värdet för hållbara egenskaper hos nya produkter. Denna utveckling är en central del inom träindustrin, som nu står inför utmaningen att estimera värdet av en hållbar produktion. Studien syftar att estimera ett värde för miljö-/klimatvänliga produkter inom träindustrin från ett kundperspektiv. Detta har gjorts genom att utföra en conjointanalys med användandet av PAPRIKA (Potentially All Pairwise RanKings of all possible Alternatives), för att bestämma den relativa betydelsen för 6 produktegenskaper. Resultatet av studien visar att priset är den viktigaste egenskapen hos trallvirke. Medelvikten för de 6 egenskaperna som inkluderats i studien är; pris (25,0%), åldring (21,9%), underhållsintervall (16,9%), fossilt kolspår (16,9%), dimensionsstabilitet (10,2%) och biocider (9,1%). Slutsatsen av studiens resultat är om sortimentet för trallprodukter ska täcka majoriteten av konsumenterna, bör man ha flera olika produkter med olika egenskaper. Resultatet tyder också på att vikten för hållbarhetsattributen kan öka ifall konsumenten blir mer informerad och får en bredare kunskap om egenskapernas innebörd.
