I’m a bit challenged and can’t figure out how to add my question to the pic, so adding it here.
We had bad snow here in New England, USA, and the rabbits could reach beyond the trunk protectors and wiped out all my kiwi vines (and fruit trees). I gathered the bitten off vines and am trying to root them in water. One of them is growing these things alongside leaves. Are these flower buds?? I’ve never had this happen before.
I should have tried to root them in the dark, and maybe removed the leaves in order to give roots time to grow, but with all the snow and trees in shambles, that was the last thing on my mind. 
I also now have no idea which ones are my male, and which ones are which of my 4 female varieties. I stuck them all together in water in my desperation.
They are flower buds. There is no way to tell if they are male or female until they develop further and open.
The stems will not likely root. Sorry.
chances are the in ground roots and remaining stems will push good growth once the weather warms.
Thanks for confirming. I have never, ever had flower buds on my kiwis - really sad that this year it would have finally happened. If I’m lucky and these are male, I might be able to use the pollen for one single spindly female vine that survived the massacre if she flowers.
I would suggest removing all but two of the buds. If you try to keep them all, they are likely to all drop off prematurely. Just one or two should last long enough to open so you can determine the sex.
Thank you for the advice!
And turns out these buds are on male Arctic/Kolomikta, the only vine pieces I found chewed up a day later, that I then had the presence of mind to tag - all others are Hardy/Arguta.
