Abstract:

The pharmacologically important alkaloids morphine and codeine are found in latex of opium poppy (Papaver somniferum). Latex is harbored in laticifers, a specialized vascular cell-type. Isolation and characterization of latex-specific genes may provide a useful tool to metabolically engineer increased alkaloid production. Previous research in the Nessler laboratory identified genes that exhibit latex-specific gene expression. Latex-specific genes were an 2-oxoglutarate-dioxygense (DIOX), involved in hydroxylation, desaturation and epoxidation reactions, and two of the major latex proteins,

Diploma thesis with the topic: Formation of yield and dry matter with genetic resources of opium poppy (Papaver somniferum L.) was worked out at the Department of botanics and plant physiology, Faculty of agrobiology, food and natural resources ČZU in Prague. The purpose of this thesis was to determine genotype and ontogenetic differences in amount of yield, production of dry mass, and value of growth-analytic characteristics in certain species of opium poppy. Diploma thesis was based on the fact that most of the studies about opium poppy (Papaver somniferum L.) are focused on the content of a

Abstract:

Czech Republic is one of the world's leading producers of the poppy seeds. Concerning the growing field area of poppy, the Czech Republic is lead producer of the poppy seeds at the international level (Vašák, 2010; Cihlář, 2012). Poppy seed is very sensitive on many internal and external factors during cultivation, especially in the beginning of germination and emergence. At present, there are not registered preparations available for seed dressing for poppy seed in the Czech Republic (Prokinová, 2006). However, there has been done many experiments based on testing of natural substances (eg. h

Abstract:

Poppy (Papaver somniferum L.) is plant which is in Czech Republic cultivated and consumed for a long time. Czech Republic was the biggest producer of poppy seeds in the world. It is not true currently but Czech Republic is still one of the most important producers of poppy. Czech growers produce high quality poppy seeds but they had several problems during last years. For example fluctuation of price of poppy and bad weather condition. Those problems influenced crop. Those complications caused that growers of poppy try to have stable yields for good profit. Yield parameters, such as amount and

Abstract:

Turkey is important major licid opium poppy (Papaver Somniferum) producer for medicinal and scientific purposes in the world and one of the two traditional producer country. The poppy seeds which are unique part of the opium poppy are used for food purpose. About 25.000 ton/year poppy seeds were produced for food purpose. Recent years morphine content of commercially available poppy seeds were speculated. Some studies have been reported that poppy seeds from different origins contain a wide variation of morphine (2 &ndash<br>294) &mu<br>g/g content. They have been used also different sample pr

Abstract:

The opium poppy, Papaver somniferum L., is a pharmaceutically important species that is of commercial significance in the state of Tasmania, Australia. Poppies are grown for seed and notably for their alkaloids, including morphine, codeine and thebaine. Alkaloids accumulate in the capsule during plant development, sequestered to vesicles within the latex of the reticulated network of laticifer cells. Laticifers, as the repository for alkaloids in poppies, are potentially an important component in the yield of alkaloids, and there are aspects of these cells that have not been fully invest

Abstract:

The current mechanisms of herbicide selectivity in poppy (Papaver somniferum L.) were examined in glasshouse and field experiments. Through measurements of contact angles of diquat solutions it was established that poppy, and the weeds fumitory, fat hen and field poppy are 'hard' to wet, whilst shepherds purse, wild radish, spear thistle and curled dock are relatively 'easy' to wet. It was revealed that diclofop-methyl has properties characteristic of a weak surfactant, compared with Agral®, a finding supported through measurements of dynamic surface tension.

Abstract:

Selenium is an essential element for human organism. One of the possible ways to increase its quantity in food is a biofortification of crops. Czech Republic is the largest producer of poppy seeds in the world, it could be therefore viable to increase the nutritional value of selenium in this crop. The goal of this thesis was a recognition of suitability of selected forms of selenium for biofortification of seeds of opium poppy (Papaver somniferum). Aside from the distribution of selenium in the plant of poppy and its accumulation in the harvested seeds this study also investigates the effect
