Question

Gibberellins can promotes seed germination because of their influence on

• A. Rate of cell division
• B. Production of hydrolyzing enzymes
• C. Synthesis of absicisic acid
• D. Absorption of water through hard seed coat

Answer 1

The correct option is B Production of hydrolyzing enzymes

The embryo of a seed is a rich source of gibberellins. After water is imbibed, the release of gibberellins from the embryo signals the seed to break dormancy and germinate. Some seeds that require particular environmental conditions to germinate, such as exposure to light or low temperatures, break dormancy if they are treated with gibberellins. Gibberellins support the growth of cereal seedlings by stimulating the synthesis of digestive enzymes such as $\alpha$-amylase that mobilize stored nutrients.

Thus, the correct answer is option B.
