Same thread w/ one response at the link ... Here is a link that might be useful: same thread

Update: some of the leaves are now starting to get wilty, but on the whole, the whole branch still looks pretty good. If I can get myself some soil today, I'll lop it off, and see what happens. If I can't, it will stay tied up against the main plant where it split, and I'll try again tomorrow. I'm so happy for all the input. Gives me some hope that maybe... maaaaaaybe, it'll fix itself.

I have no trouble rooting the Greggii's, Sylvia, by the usual method of just sticking them in potting soil in a shady area and keeping moist. If it is really woody, might want to use a little root hormone.

digdirt2: Yes, have numerous times as has Carolyn, Mule and several others have both here and on Tomatoville (as you know gb) as it has also been discussed ad infinitem on that forum. And yet, nobody has actually provided a reference. And people keep calling it a "membrane" that "seals", even though an abscission zone is not a membrane and does not seal in tomato fruit. <The original research papers were out of Kansas State University AG research station I recall and have been referenced in hundreds of articles over the years. > And yet, nobody here or at tville has ever managed to point to an actual reference in any of these hundreds of articles. I find this odd. <The research is based on the changing chemical nature of the vasculature structure between the pedicle and the abscission zone of the fruit as they ripen.> I'm going to guess that you haven't actually read the article. I actually had a friend with access look up this article for me a year or two ago, and I read it. And the article is about how, in maturing tomato fruit, the xylem (water transport vasculature) decreases and all transport of wet and dry matter into a maturing tomato fruit is taken over by the phloem (dry matter transport vasculature). It says nothing about a stop to transport of dry matter into a tomato. It certainly says nothing to support the claim that ONLY water enters a tomato from color break until it's picked and its implications actually debunk that idea. <Many scientific studies: Tomato fruit abscission studies> Did you read your search results? They have nothing to do with the question at hand and most of them are about the no-joint gene variation in which an abscission zone never forms at all (lime green salad is a variety like this, for example). <Given all that research is commonly accepted then I don't understand why it is so hard to accept the same studies done on tomato fruit. But some are determined to not accept it. That is their choice but it doesn't make the research any less valid.> Commonly accepted by whom? The people I see claiming the "sealed membrane" are all either from tville or quoting people from tville. Can you point to an independent, scientific source that says this? Because I've looked a lot, and I can't find one. The accusation that people are only believing what they want to believe can be leveled in both directions. And when you look at the actual science, it doesn't back up the "sealed membrane" camp. The fact is, tomatoes continue to get both water and dry matter and volatile compounds from the plant up until at least the point of becoming table ripe. This is not up for debate--it has been shown. Whether most human beings can detect these changes in a fruit ripened to table ripe on the vine vs. in a fruit that was picked early and ripened off the vine is, as I've always said, an individual matter, and whether the average human cares enough about subtle differences is yet another individual matter. But the "sealed membrane" claim so far looks to be folklore, not science.
