Miti inogadzirisa kukura kwezvirimwa ikirasi yemakemikari zvinhu-zvakagadzirwa zvechisikigo kana kutorwa zvakasununguka-zvinokwanisa kugadzirisa kukura nekusimudzira maitiro emiti. Maitiro avo epakati echiito ari mukutevedzera kana kukanganisa chiratidzo chekufambisa kwemahomoni echirimwa endogenous (senge auxins, cytokinins, uye gibberellins)

semugadziri wekukura kwechirimwa, Forchlorfenuron inomutsa kupatsanurwa kwesero uye kuwedzera mugariki. Miedzo yemumunda yakaratidza kuti, kana ikashandiswa nenzira kwayo, inogona kuwedzera dhayamita yemarabhu egariki ne15-20% uye kuwedzera huremu hwechirimwa chimwe nechimwe nezvikamu makumi matatu muzana.

Brassinolide is endogenous steroidal plant hormone yakatanga kuparadzaniswa kubva kune rapeseed pollen muna 1979 uye yakazivikanwa nevesainzi nharaunda muna 1996 sekirasi yechitanhatu huru yemahomoni ezvirimwa. Inoratidzwa nehukuru hwayo hwepamusoro, huwandu hwakawanda hwekuita

Sodium Nitrophenolates inomhanyisa kukura kwechirimwa, kutyora dormancy, uye kukurudzira kukura kwese. Vanodzivirira kudeuka kwemaruva nemichero, pamwe nekutsemuka kwemichero nekusvava; Pamusoro pezvo, vanovandudza kunaka kwechigadzirwa, vanowedzera goho, uye vanowedzera kuramba kwembesa kumatambudziko akasiyana-siyana ezvakatipoteredza-kusanganisira zvirwere, tupukanana, kusanaya kwemvura, kudonha kwemvura, kutonhora, salinity, alkalinity, uye pokugara.

Diethyl aminoethyl hexanoate (DA-6) ndeye yakakura-spectrum chirimwa kukura regulator. Inosimudzira kukura kwembesa, inosimudzira kutonhora uye chando kuramba, inovandudza mhando yemichero, uye inosimudzira mashandisirwo efotereza nekuwedzera chirimwa enzyme chiitiko, inosimudzira photosynthesis, uye kufambisa kupatsanurwa kwesero uye chiyero chekudya.

Zvinhu izvi zvinonyanya kuita se "zvinodzora mweya" mukati memuviri wechirimwa-zvinokwanisa kufambisa kukura kunoputika mune dzimwe nguva, uku zvichikonzera kudzikama mune vamwe. Semuyenzaniso, Gibberellic Acid (GA3) inogona kukonzera kuti mbesa diki dzikure kureba, nepo Abscisic Acid ichigona kukonzeresa kudeuka kwemuchero nguva isati yakwana.

Chlormequat chloride inoshandiswa zvakanyanya kukura kwechirimwa, basa rayo rekutanga kuvharidzira kureba kwedzinde muzvirimwa, kudzivirira pekugara, uye kukurudzira kudikitira kwezvirimwa uye kuwedzera goho.

Para-nitrophenol yakakosha organic kemikari yepakati, inonyanya kushandiswa mukugadzirwa kwemishonga, mishonga yekuuraya zvipembenene, uye dhayi, ukuwo ichishanda sereagent mu analytical chemistry.

Mumwaka wechirimo, kushandiswa kwefoliar kwe "Brassinolide + Monopotassium Phosphate + Fulvic Acid" musanganiswa wegoridhe weformula kunogona kuwedzera zvakanyanya kusanaya kwechirimwa, kunonoka kumera nguva isati yakwana, uye kukurudzira kuzadzwa kwezviyo kuti goho riwedzere. Parizvino inomira sechigadziriso chehunyanzvi chezvirimwa — segorosi, chibage, nemiriwo — muhondo yavo yekusanaya kwemvura muchirimo nemhepo inopisa inopisa.
