Hormone, which replaces the requirement of vernalisation is
1 Ethylene
2 ABA
3 Gibberllin
4 Cytokinin
Explanation:
Hormone, which replaces the requirement of vernalisaton is Gibberellin. Gibberellin overcomes vernalization requirement (low temperature) for flowering. Gibberellins affect several reproductive processes in plants. They stimulate flowering, particularly in long-day plants.
