Cytoplasmic Acidosis and Flooding Tolerance in Crop Plants
The metabolically active tissues and organs of most crop species can survive only short periods of extreme hypoxia (Jackson and Drew, 1984). We have been interested in the factors, both internal and external, that may influence how long such tissues can withstand extreme hypoxia before irreversible tissue damage occurs (Roberts, Canis, Jardetsky, Walbot and Freeling, 1984a; Roberts, Canis, Weimmer, Walbot and Jardetsky, 1984b). Because these plant tissues at some point in time inevitably succumb to extreme hypoxia, internal and external factors only affect the rate at which tissue damage accumulates following the onset of hypoxia. The factors cannot cause death, they can only influence or determine the time of death.
