A time-lapse video that depicts the progression of fire blight symptoms in three apple scion cultivars (Cripps Pink, Enterprise, and Honeycrisp). All three scion cultivars were propagated onto M.111 rootstocks. Shoots were inoculated with Erwinia amylovorastrain 153N under greenhouse conditions. Responses to fire blight may vary due to different environmental conditions, rootstocks, and Erwinia amylovora strains. (no audio)
