Vedclass · Answer

(D) Plant growth regulators (PGRs) are classified based on their physiological effects on plant growth.$1$. Plant growth promoters: These substances promote growth activities such as cell division,cell enlargement,pattern formation,tropic growth,flowering,fruiting,and seed formation. Examples include Auxins $(1)$,Gibberellins $(2)$,and Cytokinins $(4)$.$2$. Plant growth inhibitors: These substances play a role in plant responses to wounds and stresses of biotic and abiotic origin. They are also involved in various growth-inhibiting activities such as dormancy and abscission. Abscisic acid $(3)$ is the primary plant growth inhibitor.Therefore,$A$ (promoters) matches with $1, 2, 4$ and $B$ (inhibitor) matches with $3$.

Column-$I$	Column-$II$
