Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : The ratio of abscisic acid and cytokinins is the primary determinant of seed dormancy
Reason (R) : Hormonal sensitivity is a function of the hormonal signaling pathways in the target tissues.
In light of the above statements, choose the correct answer from the options given below.
EXPLANATION
Seed Development, Reserve Mobilization, & Des
- Assertion (A) is False: Primary seed dormancy is determined by the dynamic ratio between abscisic acid (ABA) (which enforces and maintains dormancy) and gibberellins (GA) (which breaks dormancy and initiates germination), not cytokinins.
- Reason (R) is True: Hormonal sensitivity depends on the density of functional hormone receptors and the activity of downstream signal transduction cascades in target cells.
- Conclusion: (A) is false but (R) is true.
Correct option: (4) (A) is false but (R) is true.
