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.
