Care tips for your orchid

wrote: The fungi themselves, growing alone, are not called "mycorrhizae". VAM mycorrhizae are produced by any of about 200 fungi belonging to the genus Glomeromycota when they grown on or in or in sufficiently close proximity to tree roots. A phylogenetic tree for that genus can be found at http://www.lrz-muenchen.de/~schuessler/amphylo/. Note that none of the species is called "mycorrhizae". If there's no fungus then there are no mycorrhizae. If there is no tree there are no mycorrhize. It's when you have _both_ that mycorrizae occur. So then grass, marigolds, grapevines, not being trees, don't have mycorrhiza? |

Annuals like a higher pH than perennials. -- Billy Bush & Cheney, Behind Bars http://www.haaretz.com/hasen/spages/946709.html http://en.wikipedia.org/wiki/Movemen...George_W._Bush |

So then grass, marigolds, grapevines, not being trees, don't have mycorrhiza? Not from my understanding. I just found this list of plants which form endomycorrhizae. Please do not quote me on the accuracy of the list. Just an example. Acacia, Agapanthus, Ailanthus, Alder, Alfalfa, Almond, Apple, Apricot, Artichoke, Ash, Asparagus, Avocado, Bamboo, Banana, Basil, Bayberry, Bean, Begonia, Black Locust, Blackberry, Box Elder, Boxwood, Buckeye, Bulbs (all), Burning Bush, Cacao, Cactus, Camellia, Carrot, Cassava, Catalpa, Ceanothus, Celery, Cherry, Chokeberry, Chrysanthemum, Citrus (all), Clover, Coconut, Coffee, Coral Tree, Corn, Cotton, Cottonwood, Crabapple, Cryptomeria, Cucumber, Currant, Cypress, Dogwood, Eggplant, Elm, Euonymus, Fern, Fescue, Fig, Forsythia, Fountain Grass, Fuschia, Gardenia, Garlic, Geranium, Ginko, Grapes (all), Grass, Gum, Hackberry, Hawthorne, Hibiscus, Holly, Hophornbeam, Hornbeam, Horsechestnut, Impatiens, Jojoba, Juniper, Kiwi, Leek, Lettuce, Lily, Locust, London, Magnolia, Mahogany, Mahonia, Mango, Maples (all), Marigold, Melons (all), Mesquite, Millet, Mimosa, Morning Glory, Mulberry, Monkeypod, Nasturtium, Okra, Olive, Onion, Pacific Yew, Palms (all), Palmetto, Pampas Grass, Papaya, Paulownia, Passion Fruit, Paw Paw, Pea, Peach, Peanut, Pear, Pecan, Pepper, Pistachio, Persimmon, Pittosporum, Plum, Poinsettia, Potato, Poplar, Raintree, Raphiolepis, Raspberry, Redbud, Redwood, Rice, Rose, Russian Olive, Ryegrass, Sagebrush, Sassafras, Serviceberry, Sourwood, Soybean, Squash (all), Strawberry, Sudan Grass, Sugar Cane, Sumac, Sunflower, Sweet Gum, Sweet Potato, Sycamore, Tea, Tobacco, Tomato, Tree-of-heaven, Tupelo, Walnut, Wheat, Yam, Yellow Poplar, Yucca. Better said, without the plant root tissues, or without the fungus tissues you cannot have a mycorrhiza. Again the word mycorrhiza is Greek. "mycor" meaning fungi. "rhiza" meaning root. It is a composite organ made up of plant root tissues and fungi tissues. Is it root or fungus? The answer is yes. People don't like that kind of question. The same site had a list of plants that do not respond to endo or ecto. They had pine and oak on the list. Anytime I dug pine or oak roots I found ectomycorrhizae. So please do not quote that list. -- Sincerely, John A. Keslick, Jr. Consulting Forester & Tree Expert http://home.ccil.org/~treeman and www.treedictionary.com Beware of so-called tree experts who do not understand tree biology. Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us that we are not the boss. |
