Summary
It was shown that abscisin II at low concentration (0.5–10−5 M) has a significant growth inhibiting effect on the sprouting of excised potato buds.
The growth accelerating effect of GA is partly suppressed by abscisin II. No effect could be observed on the length of the dormant period.
GA seems to have a negative influence on the root formation.
Combined treatment with GA and abscisin II nearly completely inhibited root formation.
