Question

Biosynthesis of gibberellin is inhibited by

• A. AMO-1618 and cyocel
• B. Cytokinin
• C. Auxin
• D. All of the above

Answer 1

The correct option is A AMO-1618 and cyocel

Gibberellins are growth hormones. They stimulate cell elongation, thus help in plant growth. But certain commercial chemicals like AMO-1618 and cyocel are used to stunt growth. The chemicals inhibit the biosynthesis of gibberellin by blocking the pathway of gibberellin synthesis.

So, the correct answer is 'AMO-1618 and cyocel'.
