THE RELATIONSHIP BETWEEN THE ATP CONTENT OF BARLEY AND VIABILITY

ATP, measured using a bioluminescence technique, is higher in viable b arley than in dead grain. This is observed for both Spring and Winter varieties. More ATP is extracted from corns whose moisture content is increased, though increasing the moisture content of dead grain has no effect on the levels of ATP extracted. The ATP measurement method, as it stands however, is insufficiently discriminatory for the absolute selection of barleys at intake.
