Vedclass · Answer

(B) Vernalization is a process where the flowering of plants is promoted or accelerated by exposing them to a period of low temperature.This process ensures that plants flower during a favorable season.The term 'vernalization' was coined by $T.D.$ Lysenko in $1928$.It is believed that a hypothetical hormone called 'vernalin' is produced in the plant as a result of this cold treatment,which triggers flowering.The perception of the cold stimulus occurs primarily in the actively dividing cells,specifically the apical meristem of the shoot or the embryo.Since both the Assertion and the Reason are scientifically accurate,but the Reason explains the location of the process rather than the mechanism of acceleration,the correct choice is $B$.

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