Default 133.3%? germination

I start 3 seeds of a variety in each container. So, I wound up with four seedlings in one container of Latah.

Under close inspection ...

(after the seedlings died due to being ultra thin and left out in 30+ mph wind gusts) ...

I found that two of the seedlings had emerged from one seed, with the seedcoat still encasing the cots of both. After removing the seedcoat, I found this seedcoat to have two chambers.

This is a first for me, making it even rarer than quadcots.

I currently have a double seed which I just saved from a supermarket Campari. I was wondering if a "Siamese" seed would sprout. I have too many plants right now, so I will find out next year!

The only times I've had greater than 100% germinatio is when seeds were stuck together when I sowed them. Sometimes it's just impossible to see those seeds stuck together, especially if the seeds are small.

I know, I know, I should inspect the seeds and crumble them apart before I sow them but often I have such a long to do list I just let nature take its course.

Carolyn, who wonders if she could even see two sprouts coming from one seed since the seed coat is busted wide open when the first one pokes out.

That looks like it may be a single plant (a quadcot with two headers).

Carolyn,

I used a different seedstarter this year. It was very fine, not the usual fairly coarse stuff I get. I plant seeds very shallow, where coarse seedstarter usually grips the seedcoat to help shed it from the seedling during emergence. This year, about 95% of my seedlings emerged with the seedcoat and a small clump of seedstarter still attached. I had a lot of cleaning to do. The two seedlings (like just about all of the other single seedlings) were well encased in just one seed. The seedlings were so thin that the seedcoat never burst open.

I think it depends on whether there were two seeds initially and two germinated and then fused.. Maybe Delerium can look at the base of that plant and see the fusion.

If that supposed one plant were removed so it could be looked at more closely, I do think it's from two unseperated seeds where the earliest growth fused.

Hard to say if Delerium's plant was a quadcot unless he remembers that it was -- but it does look like what I remember mine looking like as it got older. I had a quadcot in the dwarf project last year -





- and it did have two growing tips. I didn't keep special track of it as it got older, because by the time the others developed side suckers it really didn't look that different from any other bushy little tomato.

And Dee's picture does show a quadcot.

Cot refers to cotyledon and normally there are just two cots, sometimes three, called a Tricot, and much rarer a Quadcot.

And only ONE stem involved from the germination of one seed/

https://www.google.com/#q=tomato+quadcots

Above is a Google search with lots of good links discussing the situation.

And whether a normal two, or three or four, they are diagnosed at that early cotyledon stage.
