Question

Gibberellin facilitates seed germination by triggering the synthesis of

• A. $\alpha$-amylase
• B. $\beta$-amylase
• C. Both A and B
• D. $\alpha$-amylase and protease

Answer 1

The correct option is A $\alpha$-amylase

Gibberellic acid is a plant hormone which breaks the dormancy. Before the germination, starch nourishes seedling. It stimulates the synthesis of amylase enzyme in the aleurone cells of certain cereals. an alpha-amylase hydrolyzes starch into glucose which is used to provide nourishment to the seed embryo.

Thus, the correct answer is option A.
