Abstract

The relationship between anoxia tolerance and rates of anaerobic catabolism was studied using aged storage tissues of red beetroot. This tissue has substantial experimental advantages over most other tissues for studies on response to anoxia; even the aerated tissues do not grow, thus allowing assesment of any possible Pasteur effect. Furthermore, loss of the endogeneous dye, betacyanin, serves as a marker for death of individual cells. A high tolerance to anoxia was achieved by adding glucose and by applying a hypoxic pretreatment for 48 h (O 2 at 0.003-0.015 mol m -3 ). Such tissues survived anoxia for at least 150 h
