Fasciated stemmed dwarf photo
Here's a photo of a fasciated dwarf at 6 weeks and 3 1/3 inches. I'm pretty sure the main stem is the variety I chose to sow: Dwarf Sweet Sue. The side stem is a lighter color. Both have rugose leaves.

I've had the same thing happen this year to a Captain Lucky seedling, it's when there is one main stem but at the bottom there is another smaller one that grows off that main shoot right? I have not planted it yet as it is growing so slowly and now I have no more room. Is there any difference between a fascinated one and a normal one, once grown?

If they are indeed joined below what one cannot see in the picture, below the surface, I think it's more likely the result of a somatic mutation. Most mutations occur in seed DNA while somatic mutations occur in the DNA of a plant cell and are permanent and heritable. There are quite a few examples of somatic mutations known, even one here at Tville where the variety known as Casino Chips was a somatic mutation of the much larger variety Casino where one branch had cherry tomatoes. The variety Riesentraube gave rise to Yellow Riesentraube when just ONE fruit on a plant of the normal red ones was yellow. And I've seen a few of my own. One was Dix Doight de Naples where one branch had still red fruits but of an entirely different shape. Another was with the variety Green Gage where one branch had not the normal yellow fruits, but red fruits. Steve, do you think you could somehow seperate them and see what the root systems are like and possibly grow them individually? Carolyn

Seedling photo fasciated?
Peebee, yes my plant is growing as you describe.
Carolyn, I'm attaching an earlier photo which shows the fasciation, if that's what it is. (?) I transplanted the seedling to a 4" pot up to the point of separation. It's true, both the main stem and its leaves are darker than the "side stem" and its leaves. Do you still think this may be a mutation? Last edited by sjamesNorway; May 3, 2015 at 12:14 PM. Reason: seedling was transplanted up to the point of separation (not attachment as originallly written). |

With most true Dwarf varieties the central stem is very sturdy and usually fasciated, going back to Tomato de Laye as described in several of the links in the following Google search; https://www.google.com/?gws_rd=ssl#q=Tomato+de+Laye I'm not betting house money on this but I do think a somatic mutation has a good chance of being right. Carolyn, who also says every time I see Norway as part of your user name it brings back so many wonderful memories of visiting many places in Norway, as well as some folks, one relative actually, and also in Sweden where the Carlson side of my family came from. Ja?

My connection to Norway began as stage manager on a Norwegian cruise ship, where I met my Norwegian wife who was ship's nurse. I was born and raised in New Hampshire, but I've now been in Norway for 37 years. I'm still enthralled by the country's natural beauty. Ja! Steve |

I have an Antique Roman that appears to have two fused stems. Is this a fasciated stem or something else? The two stems go all the way down to where the roots begin and then divide up where the leaves begin.

Here is an interesting plant that has a loop or knot in the stem. There are tiny leaves growing out of the knot while the rest of the leaves appear normal. There is one leaf growing out of the knot that is normal as well.

Hopefully this is a clearer picture.
