Who named the florigen?

✅ Explanation: The term "florigen" was coined by Mikhail Chailakhyan, a Russian plant physiologist, in 1937. He proposed the existence of a universal flowering hormone that is produced in leaves under inductive conditions and transported to the shoot apex to trigger flowering.

🔑Key Points :
– Florigen Hormone
-Florigen is the plant hormone that helps in the flowering of the plant.
-It is a molecular response of the plant which helps in triggering the flowering or controlling the mechanism of flowering.
-Leaves of the plants produced the florigen and acted upon the apical meristem of the flowering bud.
-It is a protein that has multiple functions in the plant. The production of florigen is stimulated by inductive day length, and it is transferred to the shoot apex meristem for floral evocation.
-Florigen is considered universal in all flowering plants as the signal for flowering. The FT gene is regarded as the signal of florigen. The environmental conditions can regulate the expression of the FT genes, such as photoperiod, gibberellin, and vernalization.
