double root out one seed

i started these said they were yellow and this is what i saw today.

Cool - identical twins! Keep up posted on what it does.

i know i was shocked when i saw it will see where this seed goes keeping close eye on it

Hi Imazdi, i had a similar thing happen with an I.carnea

Marie - That's pretty cool!

Colin - My guess is that one of the "twins" would take over because of the competition for nutrients and the other would eventually die. I don't know if a split seeding could support two vines? Maybe I am wrong though ...

well i planted it so we will see what happens. hope it does survive.

I had one of the white dwarf do that, and it did live, didn't get very big, but each stem would bloom at the exact same time, and they did that throughout the season. If I find the photo, I'll post it.

Marie - Please show us what the seedling(s) look like once the coat comes off...

Colin - Please show us what type of leaves are on the stem on the left...are there 2 cotyledons on top of the left stems (?)...

Is the smaller hypocotyl on the right definitely fused to the stem on the left or are they actually 2 separate plants (?!) that came out of the same seed...(?!)

I have a i nil seed that had two cotyledons inside it. They were not two seeds stuck together but definitely two babies in one seed coat. They are growing side by side and seem to be ok.

Hi Marie... i think you will end up with two seedlings... twins! :-)

here are my twins separated... showing that it has two, somewhat tattered cotyledons and that it is a separate seedling, i can see no sign of any damage etc. that might indicate that they where at one time joined... they're now potted up individually (i felt like i was being cruel even though i watered them well before and after....lol)

Ron, what would it mean if it had only one cotyledon?

Ron... there wasn't anything to indicate they where joined along the hypocotyl, radical or petioles... could they may have been joined at the cotyledons?... there's too much damage to tell....

Colin - The seedlings are obviously fully developed and separate...if one of the seedlings had only 1 cotyledon , then that would indicate that there was an incomplete development of one of the 'twins'...

I don't think the seedlings were actually fused , but the cotyledons were likely crumpled together giving an appearance of 'fusion'...

The photo of the Convolvulus with only one cotyledon that Marie posted here

is very interesting...it may be able to send up a shoot with real true leaves or it may not...the shoot with the true leaves usually issues from the axis of the cotyledon stems where certain auxins accumulate and induce new shoot production...we'll see if the single cotyledon seedling having no orthodox axial area is able to produce the auxins for the real leaf stem...
