Mawonekedwe a Indole-3-BUTYRIC ACID (IBA): Indole-3-BUTYRIC ACID (IBA) ndi endogenous auxin yomwe imatha kulimbikitsa kugawikana kwa ma cell ndi kukula kwa maselo, kupangitsa kuti pakhale mizu yodziyimira pawokha, kuwonjezera zipatso, kupewa kugwa kwa zipatso, ndi kusintha mkazi ndi mwamuna maluwa Chiŵerengero etc. Iwo akhoza kulowa chomera thupi mwa wachifundo epidermis wa masamba, nthambi, ndi mbewu, ndi zoyendera yogwira mbali pamodzi ndi otaya michere.

Forchlorfenuron, yomwe imadziwikanso kuti KT-30, CPPU, ndi zina zambiri, ndiyowongolera kukula kwa mbewu yokhala ndi furfurylaminopurine effect. Ndiwopanga furfurylaminopurine wokhala ndi ntchito yayikulu kwambiri yolimbikitsa magawano a cell. Ntchito yake yachilengedwe ndi ya benzylaminopurine nthawi 10, imatha kulimbikitsa kukula kwa mbewu, kukulitsa kuchuluka kwa zipatso, kulimbikitsa kukula kwa zipatso ndi kusunga.

Thidiazuron (TDZ) ndi wowongolera kukula kwa mbewu za urea. Itha kugwiritsidwa ntchito pansi pamikhalidwe yayikulu ya thonje, kukonzedwa tomato, tsabola ndi mbewu zina. Ikamwedwa ndi masamba a zomera, imatha kulimbikitsa kudulidwa kwamasamba koyambirira, komwe kumapindulitsa pakukolola ndi makina. ; Imagwiritsidwa ntchito m'malo otsika kwambiri, imakhala ndi ntchito ya cytokinin ndipo imatha kugwiritsidwa ntchito mu maapulo, mapeyala, mapichesi, yamatcheri, mavwende, mavwende ndi mbewu zina kuti muwonjezere kuchuluka kwa zipatso, kulimbikitsa kukula kwa zipatso, ndikuwonjezera zokolola ndi zabwino.

Brassinolide (BR) ndi yosiyana ndi ena owongolera kukula kwa mbewu munjira yake imodzi yolunjika pakulimbikitsa zokolola komanso kukonza bwino. Mwachitsanzo, sikuti ili ndi ntchito zakuthupi za auxin ndi cytokinin, komanso imatha kuwonjezera photosynthesis ndikuwongolera kagayidwe kazakudya, kulimbikitsa kayendetsedwe kazakudya kuchokera kumitengo ndi masamba kupita kumbewu, kukonza kukana kwa mbewu kuzinthu zoyipa zakunja, ndi kulimbikitsa kukula kwa mbali zofooka za zomera. Chifukwa chake, ili ndi magwiritsidwe ambiri komanso magwiridwe antchito.
