Examples include 6-Benzylaminopurine (6-BA) and Forchlorfenuron (KT-30). These agents promote cell division, delay senescence, and increase the total number of cells within the fruit. Forchlorfenuron is widely applied to watermelons and melons, where it significantly promotes fruit enlargement;

To accelerate seed germination speed and increase the germination rate—thereby ensuring uniform and robust seedlings—seeds can typically be soaked for 6 hours in one of the following solutions: Gibberellic Acid at 200–300 mg/L, Sodium Nitrophenolates at 6–8 mg/L, or Diethyl aminoethyl hexanoate (DA-6) at 10–12 mg/L. All three methods effectively achieve this result.

Potato plants require a large amount of nutrients and water from the soil for growth and tuber enlargement. The development and absorption capacity of the root system determine the robustness of the potato plant, tuber yield, and quality.

Spraying eggplant leaves with 10-50 mg/L Gibberellic Acid once during flowering can promote fruit setting and increase yield; spraying tomato flowers with 10-50 mg/L Gibberellic Acid once during flowering can promote fruit setting and prevent hollow fruits.
