$I$ and $II$

Vedclass · Answer

(D) $I.$ Cytokinins are known to delay leaf senescence by promoting nutrient mobilization.$II.$ Auxins are primarily responsible for apical dominance,where the apical bud inhibits the growth of lateral buds.$III.$ Ethylene is primarily associated with fruit ripening and senescence,not seed germination. Gibberellins are the hormones that promote seed germination.$IV.$ Abscisic acid $(ABA)$,not Gibberellins,is responsible for the abscission (falling) of leaves and fruits. Therefore,statements $I$ and $II$ are correct.

Pick out the correct statements.
$I.$ Cytokinins especially help in delaying senescence.
$II.$ Auxins are involved in regulating apical dominance.
$III.$ Ethylene is especially useful in enhancing seed germination.
$IV.$ Gibberellins are responsible for immature falling of leaves.
