Question

The gibberellin which is of wide distribution in higher plants are?

• A. $G{A}_{29}$
• B. $G{A}_{32}$
• C. $G{A}_1$
• D. $G{A}_{22}$

Answer 1

The correct option is C $G{A}_1$

In recent years, there have been indications that in many plants GA${}_1$ is the most important native biologically active gibberellic acid, primarily responsible for stem elongation. So, is widely distributed in higher plants. It is generally easily transported in plants, they have been detected in phloem sap, xylem sap etc.

Therefore, the correct answer is option C.
