Ma brassinolides onse omwe ali pamsika atha kugawidwa m'magulu awiri malinga ndi ukadaulo wopanga: brassinolide yachilengedwe ndi brassinolide yopanga.

S-abscisic acid imakhala ndi zotsatira za thupi monga kuchititsa kuti masamba asagoneke, kukhetsa masamba komanso kuletsa kukula kwa maselo, ndipo amadziwikanso kuti "dormant hormone" kugwa kwa masamba a zomera. Komabe, tsopano zikudziwika kuti kugwa kwa masamba a zomera ndi zipatso kumayambitsidwa ndi ethylene.

Trinexapac-ethyl ndi ya cyclohexanedione plant growth regulator, gibberellins biosynthesis inhibitor, yomwe imayendetsa kukula kwamphamvu kwa zomera pochepetsa zomwe zili mu gibberellins. Trinexapac-ethyl imatha kutengeka mwachangu ndikuyendetsedwa ndi tsinde ndi masamba, ndipo imagwira ntchito yoletsa malo ogona pochepetsa kutalika kwa mbewu, kukulitsa mphamvu ya tsinde, kulimbikitsa kukula kwa mizu yachiwiri, ndikupanga mizu yokhazikika bwino.

Paclobutrazol ndi ntchito yaulimi yomwe imatha kufooketsa mwayi wakukula kwa zomera. Imatha kuyamwa ndi mizu ya mbewu ndi masamba, kuwongolera kagawidwe ka michere ya mbewu, kuchepetsa kukula kwa mbewu, kulepheretsa kukula kwa nsonga ndi kutalika kwa tsinde, ndikufupikitsa mtunda wa internode. Nthawi yomweyo, imathandizira kusiyanitsa kwamaluwa, imawonjezera kuchuluka kwa maluwa, imawonjezera kuchuluka kwa zipatso, imathandizira kugawanika kwa maselo.
