You grew this from a few cells of a tissue culture, wow. Did you buy one of those kits that come with jars, etc? Very interesting method. Why do this the mad-scientist way though and not use traditional cloning techniques from partial stems? Is there an advantage?
Yup, you can do it by regular cloning, but there are a couple drawbacks. Speed is one of them - I can get a lot more clones in a slightly longer period of time. Also, I can build up a clone stock and just let them sit for months in the jars with almost no light and cool temperatures which is something you can't do with regular clones. This fall, I'm going to pick the best-of-the-best plants from my garden and replicate those. That way I'll have an army of even better ones for next year.
Since everything happens in a sterile environment (like clean room sterile), I don't have to worry about bugs getting to them or things like bacterial spot no matter how long I plan on keeping them. Once the the sterile parts of the procedure is done and goes well, they require almost no care and can theoretically be kept at a non-growing pace indefinitely. I'm pretty new to this technique and have only done it with african violets, sempervivums, peppers and tomatoes. My goal is to be able to do it with bamboo, but I've got a ways to go until I can do that successfully.
In about 2-3 months I'll be trying it with some awesome Nardellos that came my way through the generosity of Justaguy (if you haven't tried his sauces BTW, they are awesome) who's also in central PA. When I do that I'll document the whole thing and take a bunch of pictures then put 'em up here.
Eventually, once I master bamboo, I'd like to move to the next level which is gene splicing. I'm at least 2 years off from that though, but you can do some pretty funny stuff with gene splicing - I guy I met at a midwest university made a corn plant that produced vanillin (vanilla) in the kernels. Imagine a spicy watermelon that comes off the vine! One could do all kinds of neat stuff (but not things that can kill the entire planet like Monsanto does, their GM products are very evil).
you gotta send me a ripe pod once they are ready
