Gibberellic Acid GA3 ndi chowongolera kukula kwa mbewu zomwe zimagwiritsidwa ntchito kwambiri m'mitengo yazipatso. Zimakhala ndi mphamvu yofulumizitsa kukula kwa zomera ndi chitukuko ndi kulimbikitsa kukula kwa maselo. Nthawi zambiri amagwiritsidwa ntchito kulimbikitsa parthenocarpy, kusunga maluwa ndi zipatso.

Hormone yakukula kwa zomera ndi mtundu wa mankhwala ophera tizilombo omwe amagwiritsidwa ntchito poyang'anira kukula ndi kukula kwa zomera. Ndi kupanga pawiri ndi zachilengedwe zomera timadzi zotsatira. Ndi gulu lapadera la mankhwala ophera tizilombo. Ikhoza kuyendetsa kukula ndi kukula kwa zomera pamene kuchuluka kwa ntchito kuli koyenera
