I've never noticed(but, then, I haven't really looked) rosette or symptoms 
of Zn deficiency in the native hickories, but I graft almost all of my 
hickory cultivars onto seedling pecan rootstocks.  Thus far, I've not 
noticed any evidence of rosetting on the hickory cultivars - but, haven't 
seen it in the pecans, either.
