Vedclass · Answer

(D) Plant growth regulators (PGRs) are classified based on their physiological effects on plant growth.$1$. Plant Growth Promoters: These are involved in growth-promoting activities such as cell division,cell enlargement,pattern formation,tropic growth,flowering,fruiting,and seed germination. Examples include Auxins,Gibberellins,and Cytokinins.$2$. Plant Growth Inhibitors: These play a role in growth-inhibiting activities such as dormancy and abscission. They also respond to wounds and stresses of biotic and abiotic origin. Abscisic acid $(ABA)$ is the primary growth inhibitor. Ethylene is a unique $PGR$ that can act as both a promoter and an inhibitor,but it is largely categorized as an inhibitor in the context of abscission and senescence.
