That's very interesting. Xon, do you have exact information about the procedure and the optimum quantity of IAA/IBA/NAA/GA/BAP for the micropropagation of figs?
George, The meristem is the growing tip. Cells from this tip are used for In Vitro propagation. The cells are cultured in sterile media that will grow any contaminant just as well (or better) than the desired plant. It is a very exacting process. Elder, I don't know if anyone has tried to simply "outgrow" the virus. The information that I've seen uses heat therapy to kill off the virus. Washington State University will "clean up" a variety for $2600, but I don't know if that includes fig varieties. The problem with In Vitro is you have to have the equipment, and the expertise to use it. It is very difficult to keep everything sterile. But I wonder if going that route is necessary. I don't see why very small tip cuttings in a fairly sterile medium, like sand, couldn't be heat treated. It isn't easy, but it would be a lot less difficult than In Vitro. To my mind another problem is the determination that the virus is actually eliminated - the indexing. From what I've seen this is being done by grafting "treated" fig wood onto (clean) fig seedlings and waiting to see if the seedlings show symptoms. I wonder if another (quicker/ easier) method could be found. I assume that GW hasn't fixed the e-mail problem yet, so I'll list my e-mail address if you folks want to get some of the more technical information discussed.
Why is it "necessary"? Even if you are certain that you have eliminated FMV or grown and FMV tree, how do you know it is going to remain FMV free? What happens when the neighbor on the other side of the fence plants an FMV infected tree? Unless you want to treat all the fig trees in all the lands this seems like a futile endeavor. I'll wait until someone invents the teleporter (like on Star Trek) then I'll beam my trees from one location to another without the FMV/RKN/spidermites/leaf-footed bugs/or whatever else is bothering them. Until then, give me $2,600 to rid my favorite tree of FMV, and I'll buy 130 new trees :D
I did not mean to imply that we should all run out and start our own labs, or that it was necessary for the proper raising of figs. However, people, this technique is with us; most orchids, asparagus, potatoes, carnations, strawberries, and a host of other plants are mostly propagated by meristem repro, and they are doing it with figs in several overseas countries. I believe I read where Edible Landscaping had purchased some fig trees propagated this way, and I located a company which will teach you the method, and will also propagate plants for you at the price of a buck a plant, 800 minimum. And that's quite a bargain. Xon and German Figfriend - if either of you give this a try, please file reports with this forum, success or failure.
I am no expert on this, but on the pointers given and some reading, I actually had known about it, specially relating to orchid propagation. I agree with fignut, that by itself, it does NOTHING to cure FMV! However, fignut also mentioned a 'heat' treatment that (maybe) does! That is GREAT news for some people that are happy with a few (good) FMV-free fig specimens to pursue (provided that there are no careless fig neighbors). For other fig collectors/traders, fuhgeddaboutit, I did. George (NJ).
German, sorry for answer later.. Usually when the forum is warming up, I'm going to the bed. 9 follow ups at this moment. Some months ago, I had searched information about this issue. Apparently, it is possible to use this method at home.
For a lot of vegetables and fruits this technique is used. I think that nobody would expend a lot of money for obtain nothing. I like to experiment and I don't believe in miraculous things, for the moment. Probably, It will be failure but don't worry ,I will keep in touch, this forum is funny.
For those with a desire to go further into this meristem method, look up a company called Kitchen Culture Kits. Also, thanks to fignut for sending four reports of successful fig meristem reproduction. There were four countries involved - Brazil, Spain, Turkey, and (drumroll, please) Nepal. The report from Turkey was particularly interesting as it contained info about the origination of Ficus carica, and the present day existence of these wild trees in Anatolia (which is in Turkey).
Martin, No, I have not tried it, yet. However, if you have a strong interest in trying it I would recommend you contact any professor who teaches microbiology at either a local university or community college. In large part micobiology involves the in vitro propagation of bacteria and fungus, and many of the procedures would be the same.
Elder, i stood up late last night searching and learned somethings and have come to the conclusion i just cannot do the process properly. Just for fun i used a double edge razor the kind i still shave with to see just whats inside a fig bud, i have a good jewlers eye piece i used for this after cutting my finger a little (that stung) i was getting what seemed like a million tiny tiny leaves unfurling. If you have ever eaten a artichoke boiled and pelled of the leaves 1 by one to get to the heart of it the best part, i reminded me of this process. In the end it simply was to small to hold very very small so afraid of dropping it and not finding it i cut in half inside its green almost a jell like looking substance i just could not ever extract that part along with the some other processes to much for me to do. What caught my eye before this when i cut the bud i looked under it as i had a tiny piece of what it was attached to and i could see some small round circular patterns within themselves it was quite a site whats inside. So in the end i learned a little bit about what is involved and also saw the beauty of the inside somewhat up close as never before. Im used to how nice the tree's look from the outside but for first time i saw a tiny bit of the inside. All in all it was interesting to see except for bloody finger. Thanks for replying. Martin
