Vedclass · Answer

(A) Vernalization is the process of inducing or accelerating flowering in plants by exposing them to low temperatures. This phenomenon was first described by $T.D.$ Lysenko in $1928$.The Assertion is correct because vernalization specifically refers to the promotion of flowering through cold treatment.The Reason is also correct because the perception of the cold stimulus occurs primarily in the apical meristem (shoot apex) of the plant,where it triggers the production of a hypothetical flowering hormone called vernalin.Since the Reason correctly identifies the site where the process described in the Assertion occurs,it serves as a valid explanation.

Assertion $(A)$: Vernalization is acceleration of subsequent flowering by low temperature treatment.
Reason $(R)$: Site of vernalization is apical meristem.
