Question
Wired Faculty App

During seed germination its stored food is mobilised by

  • ethylene

  • cytokinin

  • ABA

  • gibberellin

Answer

D.

gibberellin

Gibberellin induces aleurone cells to secrete enzyme to break stored food in 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.
