We kindly invite you to listen to the workshop led by Dr. Kinga Nowak, M.Sc. Katarzyna Broniewska and Dr. Krzysztof Ufnalski, titled “Examining of trunk interior with sonic tomography.”
Trees in human surroundings are priceless, providing numerous ecosystem services. Particularly valuable are venerable trees, with significant natural and cultural roles; each such tree serves as a habitat for hundreds of organisms and a true center of biodiversity. At the same time, trees may pose a threat, especially when their condition deteriorates to the point of increasing the risk of breaking or toppling. However, not every hollowed tree is doomed to be cut down; many can remain in our vicinity. How should we make rational decisions in this matter? A tomographic examination can help, allowing us to determine the degree of trunk decay.
We kindly invite you to listen to the workshop led by Dr. Marzenna Guzicka, titled “Plants on a micro scale. How to prepare a microscope slide?”
The method of preparing a specimen for observation under a microscope depends on its type and the research objective. It usually involves several basic steps. The biological material must be fixed, dehydrated, and then embedded in a suitable medium, such as paraffin, paraplast, or epoxy resin. Once prepared in this way, the objects can be cut into very thin sections using an appropriate microtome. After placing the sections on microscope slides, they are stained, and the stained specimen is sealed by applying a chosen medium (e.g., euparal) and covering it with a coverslip. This process yields a permanent specimen that does not dry out, shrink, or undergo biodegradation, and it can be stored for many years.
We kindly invite you to listen to the workshop led by Prof. Dominik Tomaszewski, titled “How to prepare a Herbarium?”
The idea behind a well-prepared herbarium specimen is to combine a properly dried plant specimen with information about where and when it was found. A herbarium specimen should present the plant’s key features in an aesthetically pleasing way—especially those that enable accurate identification. Well-preserved leaves and flowers are the most important. A label with details about the location and date of collection is an integral part of the herbarium specimen. The more precise this information is, the greater the scientific value of the specimen.
We kindly invite you to listen to the workshop led by Dr. Teresa Hazubska-Przybył, Dr. Mikołaj K. Wawrzyniak and M.Sc. Agata Obarska, titled “Cryopreservation of embryogenic tissues in liquid nitrogen.”
The ability to store embryogenic tissues in liquid nitrogen offers the potential to preserve the genetic-level biodiversity of certain tree species. These tissues are the most suitable material for cryopreservation due to their meristematic nature. Some of the methods developed have already been tested by commercial forestry companies. In the future, they will undoubtedly find practical applications in forestry, which is especially important in the face of ongoing climate change.
We kindly invite you to listen to the workshop led by Prof. Tomasz A. Pawłowski, titled “Proteomic analysis of tree seed germination.”
Proteomics deals with studying the identity, quantity, structure, and biochemical as well as cellular functions of all proteins in an organism, organ, or organelle, along with their variability in space, time, and physiological state. Proteomics has opened new possibilities for identifying proteins expressed during developmental processes, including the germination of tree seeds. Analyzing the physiological and biochemical functions of proteins makes it possible to understand the mechanisms that control seed germination.
