THE STORAGE OF ACORNS IN WATER
Acorns of sessile oak (Quercus petraea) will not tolerate prolonged submergence, but those of pedunculate oak (Quercus robur) survive very well in regularly changed distilled water or tap-water. Survival is considerably worse in basic river water; the difference from tap-water is likely to be due either to the greater activity of organisms promoting decay, or to the prevalence of lower oxygen-tensions in river water. Storage in water under suitably controlled conditions might be a useful practical procedure with pedunculate acorns.
