Any suggestion with this would greatly be appreciated.

This happened in at the beginning of march, i had these three plants in the basement in the southeast corner, near a window but not direct natural lighting or sunlight.  i only gave maybe one cup of water every two months since i took them in from outside in late October. These are Brifarra, and Natalina.  
i've done the scratch test and there are green showing on majority of the woods, will 
these survive or should i be looking at a major rescue before they break dormancy.
there are some mold starting form on the cracked woods also.
I am in Saskatoon, Saskatchewan, Canada, a zone 3b

Thanks

Hi radartower,
This is cold damage due to hard freeze .
They can survive but could die .
I have here in a neighbor's garden a fig tree with half the trunk dead and half alive for 2' (60 cm) of height, and then a branch growing at that height ... That one for sure wants to survive .

If those trees were mine, I would at least remove half of the top part and use them as cuttings and try to root them.
IMO, if those trees are still alive, they will send root-shoots and let those split trunk die back - so it is IMO useless to keep that wood .

One other alternative, on the first pic, there is a branch almost at dirt level. I would create a mound of dirt to include that branch in the dirt, and see if it roots directly while still attached to the tree - being still attached
can only help that branch in the rooting process .

Let us know your choices and keep us posted !
Zone3 ... Do you have white bears around ?

Thanks jdsfrance,
there are several branches that are low enough that i will mound up soil to see if i can get some roots from them.  would removing some barks to bare the woods and applying some rooting compound to help increase the chance of these branches root, IYO? 
As long as these plants will survive even for a little while after they break dormancy, i wanted to do some air layering on the upper woods and i will take some cuttings to see if i can get some roots out of them, and say goodbye to the split woods.

Thanks again for your comments and suggestions

If you want to use rooting hormone (I would) just scrape the surface bark until green is showing then put the rooting hormone on.

Thanks rcantor,
that is a great idea, will give that a try

thanks

no white bears, just brown and black ones.  white ones are further north, maybe another 1500km north of our city.
