which plant hormone promote dormancy in seed and buds??

$\huge\red{\mid{\fbox{\tt(ANSWER)}\mid}}$

abscisic acid

Gibberellins (GAs) break seed dormancy and promote germination (1, 2), and several other hormones, including brassinosteroids, ethylene, and cytokinin, have also been shown to promote seed germination (3, 4). However, abscisic acid (ABA) is the only hormone known to induce and maintain seed dormancy.

Answer 2

Answer:

Abscisic Acid (ABA) promotes seed and bud dormancy by inhibiting growth. It is one of the most important plant's growth regulators. ABA also plays an important role in the closure of stomata in plants under water stress and its presence inhibits opening.
