Question
Which of the following is not an inhibitory substance governing seed dormancy?
Abscisic acid
Phenolic acid
Para-ascorbic acid
Gibberellic acid
Plant Growth Regulators (PGRs) are broadly divided into two groups. One group is involved in growth promoting activities and includes gibberellins, auxins, and cytokinins. The other group plays an important role in growth inhibiting activities such as dormancy and abscission; abscisic acid belongs to this group . Since Gibberellic acid is classified as a growth promoter, it is not an inhibitory substance governing dormancy.
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Plant Growth and Development . Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
