[IBC] new idea
Hi all,
okay, I just thought of something that I don't really know if it is going to work, but hopefully it will. Ths is regarding to my idea of my science fair. I was thinking of finding the possibility of a tree cancer. Looking cancer as a cell that is defected, I will try to defect a tree cambrium cell or a leaf cell to c if a tree cancer is possible. I don't know if it will work, but if it does, hopefully it will carry me to the nationals. Please give me idea or feedback. Thank you, Luc Tran __________________________________ Do you Yahoo!?

I was thinking of finding the possibility of a tree
cancer. Looking at cancer as a cell that is defective, Yes and no. The main defect in cancer cells is unregulated growth. If you use the analogy of a tumor, rather than cancer, you can come up with an interesting project. Plants, especially woody plants, do have the capability of producing various kinds of galls, cankers, and excessive callous tissue, which are similar to tumors and granulomas in animals. However, probably due to the differences in the vascular system, I have never heard of gall tissue in a plant metastasizing the way cancer metastasizes in animals. Also, while tumors or cancer in animals are sometimes caused by infection or environmental disturbance, & sometimes by a breakdown in the regulatory system, as far as I know, the analagous growths in plants are always caused by the environment, usually infection. Go with it. You should be able to get photomicrographs of animal tumor cells and comparable plant tumors, as well as animal and plant photographs, and some illustrative live plants.

In trees, that's called a gall. It can be caused by various things: nematodes, insects, fungi, viroids, or bacteria. The most famous tree gall is "crown gall", caused by Agrobacteria tumefaciens. You could re ad up on it; it's very interesting. However, it's a difficult science project, and infecting bonsai would be a rather cruel thing to do. I would once again steer you away from "bonsai" as a project; trees are hard to do experiments on, even for tree pathologists. One tree pathologist I know did a series of experiments on IVY, because it is more tractable than trees, and he could do larger experiments. Judges in these contests are looking for good experimental design; they aren't expecting you to make a major discovery. Having said that, if you are determined to do an experiment on bonsai, why not take a single bonsai with many branches and try to take air-layers using different methods? Everyone on the list has a different technique (aluminum foil versus plastic wrap; s phagnum versus newspaper, girdling versus slits, etc.), and it would be fun to compare them. ************************************************** ****************************** ++++Sponsored, in part, by Lisa Kanis++++ ************************************************** ****************************** -- The IBC HOME PAGE & FAQ: http://www.internetbonsaiclub.org/ -- +++++ Questions?

One virus (I think, might be bacteria) causes the leaves of red poinsettias to have white streaks. Since people like this variation in poinsettias so those with the virus are cultivated and sold at a higher price than healthy plants. Billy on the Florida Space Coast Back in the "Tulipmania" of the 1600s, virus-infected tulips with streaked flowers were sold at higher prices than other tulips; however, aphids would spread the streaking to pure-color tulips, so these kinds of cultivars were abandoned in favor of strea ked tulips caused by genetic mutation. I am positive than no virus-infected poinsettias are on the market! But it's absolutely amazing what breeders have done with poinsettias; they are pink, yellow, spotted, striped, curled and crisped.... There's a new powdery mildew on poinsettia, and we've tried in vain to convince growers that the white spots look like christmas snow on the petals...... ************************************************** ****************************** ++++Sponsored, in part, by Lisa Kanis++++ ************************************************** ****************************** -- The IBC HOME PAGE & FAQ: http://www.internetbonsaiclub.org/ -- +++++ Questions?
