Vedclass · Answer

(A) $I.$ Cytokinin is known to delay leaf senescence by promoting nutrient mobilization.$II.$ Auxin is responsible for apical dominance,where the apical bud inhibits the growth of lateral buds.$III.$ Ethylene is primarily associated with fruit ripening and horizontal growth of seedlings,not seed germination (which is primarily promoted by Gibberellins).$IV.$ Gibberellins promote growth and seed germination; the immature falling of leaves (abscission) is primarily promoted by Abscisic Acid $(ABA)$ and Ethylene.Therefore,statements $I$ and $II$ are correct.

Choose the correct statement:
$I.$ Cytokinin - Delay of leaf senescence
$II.$ Auxin - Apical dominance
$III.$ Ethylene - Seed germination
$IV.$ Gibberellins - Immature falling of leaves
