Zowongolera zakukula kwa zomera ndi gulu la zinthu zopangidwa ndi mankhwala-zopangidwa mwachisawawa kapena zotengedwa mwachibadwa-zomwe zimatha kusintha kakulidwe ndi kakulidwe ka zomera. Njira yawo yayikulu ndikutsanzira kapena kusokoneza katulutsidwe ka mahomoni am'mera (monga ma auxins, cytokinins, ndi gibberellins)

monga chowongolera kukula kwa mbewu, Forchlorfenuron imathandizira kugawanika kwa maselo ndikukulitsa adyo. Mayesero akumunda awonetsa kuti, akagwiritsidwa ntchito moyenera, amatha kuwonjezera kukula kwa mababu a adyo ndi 15-20% ndikuwonjezera kulemera kwa mbewu iliyonse ndi pafupifupi 30%.

Brassinolide ndi endogenous steroidal plant hormone yomwe idasiyanitsidwa koyamba ndi mungu wa rapeseed mu 1979 ndipo idazindikirika ndi gulu la asayansi mu 1996 ngati gulu lalikulu lachisanu ndi chimodzi la mahomoni azomera. Yodziwika ndi mkulu dzuwa, yotakata sipekitiramu ntchito

Sodium nitrophenolates imathandizira kukula kwa mbewu, kuswa dormancy, ndikulimbikitsa chitukuko chonse. Amaletsa kukhetsedwa kwa maluwa ndi zipatso, komanso kusweka kwa zipatso ndi kufota; Kuonjezera apo, amapangitsa kuti zinthu zikhale bwino, zimachulukitsa zokolola, komanso zimathandiza kuti mbeu zisawonongeke ndi zovuta zosiyanasiyana zachilengedwe monga matenda, tizirombo, chilala, madzi oundana, kuzizira, mchere, mchere, ndi malo ogona.

Diethyl aminoethyl hexanoate (DA-6) ndi chowongolera kukula kwa mbewu. Imalimbikitsa kukula kwa mbewu, imathandizira kuzizira ndi chisanu, imapangitsa kuti zipatso zikhale bwino, komanso imathandizira kagwiritsidwe ntchito ka feteleza powonjezera ntchito ya michere ya zomera, kupititsa patsogolo photosynthesis, ndikuthandizira kugawikana kwa ma cell ndi michere.

Zinthuzi zimagwira ntchito ngati "zowongolera maganizo" m'thupi la zomera-zomwe zimatha kuyambitsa kukula kwamphamvu nthawi zina, kwinaku zimapangitsa kuti pakhale bata. Mwachitsanzo, Gibberellic Acid (GA3) imatha kupangitsa mbewu za nandolo zazing'ono kukula, pomwe Abscisic Acid imatha kuyambitsa kukhetsa zipatso msanga.

Chlormequat chloride ndiyomwe imagwiritsidwa ntchito kwambiri poletsa kukula kwa mbewu, ntchito yake yayikulu ndikuletsa kutalika kwa tsinde muzomera, kuteteza malo ogona, komanso kulimbikitsa kufupikitsa kwa mbewu komanso kukulitsa zokolola.

Para-nitrophenol ndi chinthu chofunikira kwambiri chapakatikati, chomwe chimagwiritsidwa ntchito popanga mankhwala, mankhwala ophera tizilombo, ndi utoto, komanso ngati reagent mu analytical chemistry.

M'nyengo ya masika, kugwiritsa ntchito foliar ya "Brassinolide + Monopotassium Phosphate + Fulvic Acid" kungathandize kuti mbeu zisawonongeke ndi chilala, kuchedwetsa kumera msanga, komanso kulimbikitsa kudzazidwa kwa tirigu kuti zokolola ziwonjezeke. Pakalipano ndi njira yodziwira mbewu monga tirigu, chimanga ndi ndiwo zamasamba pankhondo yawo yolimbana ndi chilala cha masika ndi mphepo yamkuntho.
