"It is best to avoid using full or near full strength (95-100%) alcohol because it may dehydrate and injure basal stem tissue".
He goes on to say:
"Lack of practical experience with this technique can result in killing or severely injuring cuttings during treatment. Solution concentrations must be carefully adjusted to the species and degree of lignification of the cutting; duration of treatment must also be not too long."
Other factors he considered:
Alcohol evaporates rapidly therefore the auxin concentration of the solution will elevate as the solution becomes reduced.
Too high a concentration of alcohol will cause the cuttings to die.
Cuttings may drag in excess moisture to the solution therefore changing the concentration.
Alcohol may absorb water from humid air.
Surely (3) and (4) may not be as important a consideration (in production) than (1) or especially (2).Other factors to consider:
