Mu rwego rwo kurinda ibimera, abashinzwe imikurire y’ibihingwa (PGRs) bafasha cyane cyane mu kurwanya udukoko n’indwara duhindura imikurire n’iterambere ndetse no kongera kwihanganira imihangayiko; bagize kimwe mubikoresho bya tekiniki byingenzi murwego rwa "Kurinda Ibimera Byatsi ".

Ibihe bibi bisanzwe mubihe byizuba - nkubushyuhe bwinshi, urumuri rwizuba rwinshi, n amapfa - akenshi biganisha kumikurire ikabije yibimera (etiolation) no kudakora neza kwibihingwa. Abashinzwe gukura kw'ibimera bakemura ibyo bibazo bahindura uburinganire bwa hormone endogenous;

Mepiquat Chloride kuri Pamba: Nuburyo bukoreshwa cyane. Iyo ushyizwe mugihe cyo kumera kumurabyo hakiri kare, igenzura neza uburebure bwibimera, ikabuza kuramba cyane kwamashami yimbuto, kandi ikagabanya kumeneka kwa boll mugice cyo hagati no hepfo yikimera, mubisanzwe bigatuma umusaruro wiyongera 10% kugeza kuri 20%.

Igenzura ryikura ryibimera nicyiciro cyibintu bya shimi-bigizwe nubukorikori cyangwa byakuwe muburyo busanzwe - bushobora guhindura imikurire niterambere ryibimera. Uburyo bwabo bwibanze bwibikorwa bishingiye ku kwigana cyangwa kubangamira ihererekanyabubasha ryerekana imisemburo ya endogenous hormone (nka auxins, cytokinine, na gibberelline)

nk'umuteguro wo gukura kw'ibimera, Forchlorfenuron itera kugabana ingirabuzimafatizo no kwaguka muri tungurusumu. Ikigeragezo cyo mu murima cyerekanye ko, iyo gishyizwe mu bikorwa uko bikwiye, gishobora kongera umurambararo wa tungurusumu ya tungurusumu 15-20% kandi bikazamura uburemere bw’ibiti ku giti cye hafi 30%.

Brassinolide ni imisemburo ya endogenous steroidal hormone yatangijwe bwa mbere n’udusimba twafashwe ku ngufu mu 1979 kandi yemerwa n’umuryango w’ubumenyi mu 1996 nk’icyiciro cya gatandatu cy’imisemburo y’ibimera. Kurangwa nubushobozi buhanitse, ibikorwa byinshi

Sodium Nitrophenolates yihutisha imikurire y’ibihingwa, guca ibitotsi, no guteza imbere iterambere muri rusange. Zirinda kumeneka indabyo n'imbuto, kimwe no kumena imbuto no kugabanuka; byongeye kandi, bitezimbere ubwiza bwibicuruzwa, byongera umusaruro, kandi byongera ibihingwa birwanya ibibazo bitandukanye by’ibidukikije - harimo indwara, udukoko, amapfa, amazi y’amazi, ubushyuhe bukonje, umunyu, alkaline, hamwe n’uburaro.

Diethyl aminoethyl hexanoate (DA-6) nigenzura ryikura ryibihingwa. Itera imbere gukura kw'ibihingwa, ikongera ubukonje n'ubukonje, ikanoza ubwiza bw'imbuto, kandi ikazamura imikoreshereze y'ifumbire mu kongera ibikorwa bya enzyme y'ibimera, kongera amafoto ya fotosintezeza, no koroshya igabana ry'uturemangingo no kuringaniza intungamubiri.

Ibi bintu bikora cyane nka "kugenzura imiterere " mumubiri wibimera-bishobora gutwara imikurire iturika mubihe bimwe na bimwe, mugihe bitera gusinzira neza mubindi. Kurugero, Acide ya Gibberellic (GA3) irashobora gutuma ibihingwa byamashaza ya dwarf bikura birebire, mugihe Acide Abscisic irashobora gutuma imbuto zera imburagihe.
