Burr-knot, an aggregation of dormant root initials, is common to some apple cultivars. They have been observed on clonal apple rootstocks in Arkansas. Some problems associated with these stocks mat be related to their presence.
Swingle (6) reviewed the early literature and cited an 1809 report by Knight, who described the burrs as, "conigeries of points capable of forming roots under favorable conditions". He credits Loudon with the name burr-knot which first appeared in print in 1829.
