Select the incorrect statements.

Options

  1. AABA acts as antagonist to GAs.
  2. BEthylene can act both as a promotor and an inhibitor of growth activity.
  3. CAuxin and ethylene promotes apical dominance.
  4. DABA promotes seed germination.

Correct answer

D. ABA promotes seed germination.

Step-by-step solution

ABA is a growth inhibitor which inhibits seed germination and promotes seed dormancy. It acts opposite or antagonistic to GAs. Ethylene is promoter at low concentration but at high concentration it function as inhibitor. Ethylene is synergistic with auxin at low concentration and promotes apical dominance.
