Rooting woody cuttings

I looked up Gelsemium sempervirens in Dirr's "Manual of Woody Landscape Plants: " Propagation: Seeds, semi-yardwood or hardwood cuttings: cuttings collected in August rooted 100% when treated with 3000 ppm IBA and placed in peat:perlite under mist."  I'm afraid I don't know what IBA is. 
 
What I wanted to point out is that the root that will grow in water are not the same roots that will grow in the soil. They have to take up nutrients differently. If you root the plant in water and then put it in soil it will need to develop the "soil" roots.

Subject: Rooting woody cuttings

I am trying to root woody cuttings of Carolina Jessamine (Gelsemium
sempervirens).

I put some in soilless medium and some directly in water. The ones I put in
the water are all sending up new growth but have no roots. Some of the
nodes under water have swollen, though.

The ones in the medium have lost their original leaves and are starting to
put out new ones. There are tiny roots in the one I unpotted to check on
it.

My question is: should I leave the ones in the water alone until they form
roots? Or should I pot them up and hope they'll form roots?
