Rooting stubborn vines, advice needed!

Hey everyone, I'm having some trouble getting my schisandra vine cuttings I took in early July to root. Here's where I'm at so far;

As you can see, they've developed thick calluses but refuse to produce roots. I've had no problem getting cannabis, haskap, or arctic beauty kiwi vines to root using the same methods (clonex, root plug, dome), so any advice on where to go from here would be greatly appreciated!

warning I tried to find a guide but everything I found searching gave me old but also answers of getting good cuttings hard. tried!



For propagation by hardwood cuttings the cuttings were made in February and March before the beginning of the vegetation period. The cuttings were kept in sand and sawdust until the danger of frost at ground level passed and then they were planted into cold frames.
The cuttings were subjected to treatment with a weak (pink in colour) solution of KMnO4 and with growth regulators, with IBA at 0.005% for a period of 16 hours or with IAA at 0.01% for a period of 5 hours [HROMOVA, 1980]. They were planted into cold frames into two substrates: sand or sand + peat in a ratio of 1:1 and minimum 24% artificial mist. After one year the cuttings were planted into containers or in the open field.
Having in view that by generative propagation some qualities specific to the mother plant appear or disappear and vegetative propagation presents some difficulty, the initiation of in vitro cultures was tested for this species.
The plant material consisted in various explant types: apical meristems, lateral meristems of the 2nd, 3rd, 4th, 5th and 6th degree, fragments of juvenile leaves, shoot fragments from the apical part, shoot fragments with lateral meristem, Fragments of young leaves with veins, ovules, ovary with a fragment from the stem, stem fragment with the apical meristem. For culture initiation nine experimental variants were tested, with MS (1962) basal medium and various concentrations of plant hormones (Tab. 1).
The operations were carried out according to the standard laboratory procedures.”

Thanks for the replies!

They were just starting to lignify when I took them, so I believe that makes them either softwood or semi-hardwood. "...it was established that the stimulators IBA and IAA-0,01% plus sucrose at 10 g/l concentration stimulate rooting." Maybe I'll try some raw honey on one.

I used to get calluses like that fairly often when I cloned in wicking perlite cups, most of them seemed to root eventually, so I might throw one in one of those and forget about it for a while.

Air pruning sounds like a good option, I'll have to give that a try next year if my cuttings don't pan out.
