Question

Chemical agent that has important role in flowering is

• A. Fluorocarbon
• B. GA${}_3$
• C. Florigen
• D. Auxins

Answer 1

Answer: (C)

a) Fluorocarbon is a compound containing only carbon and fluorine. These compounds can be used as refrigerants, solvents, and anesthetics.

b) Gibberellic Acid or GA${}_3$ is a plant hormone which regulates various developmental processes, including stem elongation, germination, dormancy, flowering, flower development and leaf and fruit senescence.

c) Florigen also called flowering hormone is the hypothesized hormone-like molecule responsible for flowering in plants.

d) Auxins are a class of plant hormones responsible for stem elongation and maintaining apical dominance.

So the correct answer is C.
