I think you could be right on the dormancy if the damage takes place early in the growing season before the root has time to develope its new growth bud for the next year. Here's what Scott Persons Ginseng book has to say about blight or damage.
\"Blight: pg 115 \"Usually only the foliage dies stopping growth and eliminating the potential for seed production for seed production that season, but the ginseng root survives to sprout a new top the next spring. ....Only if Alternaria(or any other disease or damage)destroys a young plant early in the summer, before the bud has formed for next year's top, is there a risk of root loss. Older, larger roots will usually be able to draw upon their energy reserves to produce a new bud for the following season without the aid of any foiage.\"
I believe that if damage, disease or stress happens before the root can develope the new bud for the next season then it could go dormant until it can develope a new bud. Then again I think that ginseng has a mind of it's own and will go dormant when it darn well pleases.
