The results are presented of three-year studies on the effect of presowing treatment of the seeds of eight pea cultivars on the dynamics of changes in ATP content in germs during 7-day germination. The rate of respiration of germinating seeds of two pea cultivars and the effect of two seed dressing preparations on this process was also assayed.

The experiment permitted the conclusion that the dynamics of changes in the content of ATP in germinating seed was varied and characteristic of each pea cultivar. The natural energy transformations which accompanied the germination process were significantly changed by the applied seed dressing preparations, particularly after 48 h. This chiefly concerned the cultivars Nike, De Grace, and Delisa which demonstrated the greatest sensitivity to seed dressing treatment in the entire course of the experiment.
