It's been a while since I've asked an unanaswerable question so here's
one...Francelle? mentioned that she thought pineappleing was brought on
by stress (drought & heat in her case) & I've commented a number of
times about rot susceptibility being brought on by stress (too abrupt
swings in temps (usually abrupt severe freezes after warm spells) or
water (usually sudden deluge after drought, or sudden drought & heat
after cool wet early spring).
I wonder if a tendency to be susceptible to pineappleing in drier
climates would be any indication of tendency to be susceptible to stress
in general?
In other words, what are plant cells & meristems & hormones & other
plant stuff doing (or not doing) under stress conditions to make them
vulnerable to 'accidents' of one sort or another? Any theoretical
reason to think there might be similarities of response?
I keep hoping there will be some indicator of stress, disease & pest
resistance that growers/hybridizers in other climates could use to help
select cultivars more adaptable to a wider range of climates....maybe
help select cultivars that will make rutabagas & turnips on the west
coast, but peanuts farther east & south <g>
