In the terms of seed germination, which of the following enzymes are antagonist?

PLANT GROWTH REGULATORS
NEET
1

Auxin and cytokinin

2

Zeatin and ethylene

3

GA and ABA

4

Ethylene and IAA

Solution:

Gibberellic Acid (GA) and Abscisic Acid (ABA) are plant growth regulators that act antagonistically concerning seed germination. GA (Gibberellins) promotes seed germination, breaking dormancy, while ABA (Abscisic Acid) inhibits seed germination and promotes dormancy. This makes them an antagonistic pair in the context of seed germination.
