My memory of the performance of pears on Provence quince were a little
off. After checking my orchard notes, I found that I've had several
pears die of fireblight on Provence quince and the whole thing,
including the stock was killed. The following numbers shouldn't be
taken very seriously, 'cause it was not a controlled experiment. There
were several different scion varieties on each type of stock and the
scions were not replicated on each stock for starters. Anyway, FWIW:
Stock Percent killed by fireblight (scion
killed completely)
