video content: This footage shows the sophisticated survival strategies of the annual sundews. Living a full life-cycle, from germination to flowering and seed-production, within one single season needs highly effective trapping strategies to get enough protein. The sundews in section Arachnopus, Coelophylla and Thelocalyx manage that with the most prominent and fast snap-tentacles, yellow light reflecting lens-headed tentacles and other adaptations to make as much prey as possible, and to produce seeds even under bad conditions. Our film shows several pictures of these species that have never been shown before. Additional Information: We (my wife Irmgard and I) own the copyright for this film and have permission to use the picture of Dr. Barry Rice, and the SEM images made by Dr. Regina Kettering, for our common project with Prof. Dr. Stephen Williams, to investigate the lens-tentacles of Drosera hartmeyerorum. Enjoy Your Meal Part 1: Mice eating Nepenthes truncata Siegfried R.H. Hartmeyer Technical Summary of video content: Part 1: A garden pond wich contains small peaty islands for Darlingtonia, Dionaea, Drosera and Sarracenia does not only look nicely in the early summer, as it is also soon attracting small animal carnivores as amphibes, reptiles and predatory insects like dragon flies and mantis. But there is even more to be seen when a large Roridula dentata at our balcony catches a big wasp which is immediately attacked by a hungry Pameridaea bug. And things become actually dramatically with the pictures of our multifold mice killing Nepenthes truncata. Additional Information: We (my wife Irmgard and I) own the copyright for this video series in 2 parts.   Enjoy Your Meal Part 2: Enzyme-testing with Byblis, Drosera and Roridula Siegfried R.H. Hartmeyer Technical Summary of video content: Part 2: Carnivorous plants digest their prey with proteolytic enzymes, or they profit from the enzymes in the stomache of mutualistic arthropodes living on the plant. But how is it possible to detect the enzymes. Fortunately there exists a simple and cheap adapted photo-film test for plants with sticky traps that is suitable for your own experiments or the use in schools. This film shows the procedure of the test with Byblis filifolia, Byblis liniflora, Drosera adelae, and Roridula dentata. Also possible problems with the evaluation of the test strips are discussed in detail. Well, you may understand the end of this part 2 only if you have seen part 1(smile!).

Time-Lapse Characterization of Arabidopsis Starch Metabolism Mutants Zach Jarou Technical, Part of a Series Summary of video content: During the early exponential growth phase of plants, the majority of photoassimilates are reinvested into new leaf material. Leaf area, one of many growth parameters, has been examined by time-lapse photography in Arabidopsis starch metabolism mutants. The irregular shape of leaves can make measurement by traditional means difficult, especially for large numbers of plants. By taking a digital picture of the leaves to be measured, along with an object of known size, the pixel area of the leaves can be can quantified into physical units. This is accomplished using the color range and histogram tools in Adobe Photoshop. A screen capture demonstration of this process is available on YouTube (http://www.youtube.com/watch?v=E3O-V6WLw0g). The accompanying song, “Claire de Lune,” was composed by Claude Debussy and performed by pianist Van Cliburn.   Reincarnation of Trudy, a Titan arum in Berkeley Seung Yon (Sue) Rhee General Summary of video content: This video shows shows the rapid growth and 'flowering' of the inflorescence of Titan arum (commonly known as the corpse plant) at the UC Botanical garden in Berkeley in June of 2009. Affectionately called 'Trudy' by the garden staff, this plant grew at an average of 2-3 inches per day for about a week until the spathe (the dark purple 'skirt' of the plant) started opening on June 23, 2009. During flowering, the plant makes rotting-flesh smell by producing stinky metabolites, putrescine and cadaverine, to attract flies and beetles to pollinate. Out of Thin Air Nancy Muleady-Mecham General Summary of video content: This is a audio/visual reading of the illustrated book, Out of Thin Air, A Story of Big Trees, by Nancy Muleady-Mecham, submitted for consideration by www.chlorofilms.org botany movie contest. It is a story about where trees com from and how important they are to the carbon cycle of our planet. Illustrated by Robert Muleady, Designed by Sandra Kim Muleady. Copyright 2009 by Nancy Muleady-Mecham. Additional Information: The fidelity of the You Tube video does not do the film justice. It looks grainy and colorless compared to the original wmv which is available. Thank you.   Kenaf Callus Hoedown Noah Flanigan General Summary of video content: Our video is intended to be a quirky and fun, yet informative demonstration on the early steps required to initiate a plant tissue culture. We employed stop motion techniques throughout the film to show seed sterilization and germination to provide axenic plant tissue for culture. This is followed by sterile dissection of cotyledon and hypocotyl regions which

Fertile Eyes (crpVideo)

Here is the story of pollination, pollen germination on the flower's stigma, pollen tube elongation through the carpel, and double fertilization of the ovules deep within the ovaries.

Natural priming (crpVideo)

Priming is a widely used technique to enhance the seed potential in relation to the range and uniformity of germination. Priming consists in a controlled imbibition of seeds in order to improve some metabolic events without germination to be completed. In the soil seed bank, seeds are exposed to a variable environment including variations in temperature and water

Time-lapse photography was used to show growth and development during germination and flower production of a few plant species. Light micrographs of prepared slides of various anatomical stages of flower development
