Popis: (.)Fruit of Delicious, a relatively resistant cultivar, and Rome Beauty, a susceptible one, became infected more frequently when injured with bruising or large punctures than with small punctures. Blight developed on 4% of Rome Beauty fruit that were punctured but not artificially inoculated. Moreover, only 1% of 125 surface-disinfested Rome Beauty fruit, collected from apparently healthy trees, developed blight symptoms during a 4-mo cold storage period, compared to as much as 15% of fruit taken from blighted trees (.)
