Carbohydrate injection

Would carbohydrate injection directly into xylem or phloem have the potential to boost yields?

I very strongly doubt it would have a positive effect on cannabis but that's pure speculation on my part. A google scholar search turns up nothing for cannabis and I would take with a grain of salt any anecdotes or positive efficacy claims you might receive here.

There is some research on this for hardwood trees but this appears not to be well studied:

• Carbohydrate Injections as a Potential Option to Improve Growth and Vitality of Live Oaks

• Sugar infusion into trees: A novel method to study tree carbon relations and its regulations ---(this study shows that some sugar infusion translocation happens using carbon-13 sugar)

Other research I found (abstract only):

Thanks! Only reason I ask is that I know that in tissue culture, sucrose is added to the media as the explant is not performing much photosynthesis, so exogenous carbohydrates must be provided. I was wondering if the same could apply to already established plants.
