Question
During seed germination its stored food is mobilised by
-
ethylene
-
cytokinin
-
ABA
-
gibberellin
Solution
D.
gibberellin
Gibberellin induces aleurone cells to secrete an enzyme to break stored food in the seed. Cytokinines promote nutrient mobilisation, which helps in the delay of leaf senescence.
ABA plays an important role in seed development, maturation and dormancy. Ethylene induces fruit ripening, breaks seed dormancy.
