Step-by-step solution

Cytokinins promote nutrient mobilisation, which helps in the delay of leaf senescence. The ability of gibberellins to cause an increase in length of axis is used to increase the length of grapes stalks. Auxin is used to induce parthenocarpy in tomato. Ethylene stimulates apical hook formation in dicot seedlings.
