Compound sodium nitrophenolate (Atonik) ndiwowongolera bwino kukula kwa mbewu. Imakhala ndi magwiridwe antchito apamwamba, osawopsa, osatsalira, komanso kugwiritsa ntchito mosiyanasiyana. Imatchedwa "Green Food Engineering Recommended Plant Growth Regulator" ndi International Food and Agriculture Organisation. palibe zotsatira zoyipa kwa anthu ndi nyama.

Thidiazuron (TDZ) ndi mchere makamaka wopangidwa ndi potassium dihydrogen phosphate ndi thiadiazuron. Zili ndi zotsatira zambiri pakukula ndi kukula kwa mitengo ya zipatso: kuchulukitsa zokolola, kupititsa patsogolo khalidwe, kupititsa patsogolo kukana matenda, etc. Thidiazuron (TDZ) ikhoza kulimbikitsa photosynthesis, kupititsa patsogolo kugwiritsa ntchito zakudya za zomera, kuonjezera chiwerengero cha maluwa ndi khalidwe la zipatso.

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.
