(1) Calcium Prohexadione: Ọ bụ ụdị ihe mgbochi uto osisi ọhụrụ.
Ọrụ ya bụ na ọ nwere ike igbochi GA1 na gibberellin, belata ogologo osisi, ma si otú a chịkwaa uto osisi. N'otu oge ahụ, ọ nweghị mmetụta ọ bụla na GA4 nke na-achịkwa ọdịiche nke okooko osisi na mmepe mkpụrụ.
E wepụtara calcium Prohexadione na Japan na 1994 dị ka ihe na-egbochi uto acyl cyclohexanedione. Nchọpụta nke calcium prohexadione dị iche na nke nnu ammonium quaternary (chameleon, mepinium), triazoles (paclobutrazol, alkene) ihe na-egbochi uto osisi dị ka oxazole) emepụtala ubi ọhụrụ nke mgbochi mmalite nke biosynthesis gibberellin, a na-erekwa ya ma jiri ya eme ihe nke ukwuu na Europe na United States. Ugbu a, ụlọ ọrụ dị n'ime obodo na-echegbukarị prohexadione-calcium, isi ihe kpatara ya bụ na ma e jiri ya tụnyere triazole retarders, prohexadione-calcium enweghị nsí fọdụrụ na osisi na-agbanwe agbanwe, enweghị mmetọ na gburugburu ebe obibi, ma nwee uru dị ukwuu. N'ọdịnihu, ọ nwere ike dochie ihe na-egbochi uto triazole, ma nwee ohere itinye ya n'ọrụ sara mbara n'ubi, osisi mkpụrụ osisi, okooko osisi, ihe ọgwụ ndị China na ihe ọkụkụ akụ na ụba.
(2) Paclobutrazol: Ọ bụ ihe na-egbochi gibberellic acid nke osisi. Ọ na-enwe mmetụta nke igbu oge uto osisi, igbochi ogologo osisi ihe ubi, ime ka internodes dị mkpụmkpụ, ịkwalite ịkọ ihe ubi, ịbawanye nrụgide osisi, ịkwalite ọdịiche okooko osisi na ịbawanye mkpụrụ. Paclobutrazol dabara adaba maka ihe ọkụkụ dịka osikapa, ọka wit, ahụekere, osisi mkpụrụ osisi, soybean, ahịhịa, wdg, ma nwee mmetụta dị ịrịba ama nke ijikwa uto.
Mmetụta ọjọọ nke paclobutrazol: Ojiji gabigara ókè nwere ike ibute osisi dwarf, mgbọrọgwụ na tubers gbagọrọ agbagọ, akwụkwọ gbagọrọ agbagọ, okooko osisi na-adịghị mma, mwụfu akwụkwọ ochie n'okpuru ya tupu oge eruo, yana akwụkwọ ndị na-eto eto gbagọrọ agbagọ ma na-ebelata. N'ihi ogologo oge nke irè paclobutrazol, ojiji gabigara ókè ga-anọgide n'ime ala, ọ ga-emekwa ka ihe ọkụkụ na-esote ghara ịmị mkpụrụ, na-ebute enweghị mkpụrụ, na-apụta n'oge, obere ọnụego mpụta mkpụrụ, na nkwarụ mkpụrụ na ihe mgbaàmà ndị ọzọ na-egbu egbu.
(3) Uniconazole: Ọ bụkwa ihe na-egbochi gibberellin. Ọ nwere ọrụ nke ịchịkwa uto ahịhịa, ime ka internodes dị mkpụmkpụ, osisi dwarfing, ịkwalite uto mkpuru osisi n'akụkụ na ọdịiche okooko osisi, na ime ka iguzogide nrụgide dịkwuo elu. N'ihi njikọ carbon okpukpu abụọ nke paclobutrazol, ọrụ ndu ya na mmetụta ọgwụ ya dị ugboro isii ruo iri na okpukpu anọ ruo iri karịa nke paclobutrazol, n'otu n'otu, ihe fọdụrụ n'ala dị naanị ihe dị ka otu ụzọ n'ụzọ anọ nke paclobutrazol, na arụmọrụ ya. Ọnụego ire ere na-adị ngwa ngwa, mmetụta ya na ihe ọkụkụ ndị na-esote bụ naanị 1/5 nke paclobutrazol.
Mmetụta ọjọọ nke uniconazole: mgbe ejiri ya mee ihe gabiga ókè, ọ ga-akpata nsị phyto, na-akpata ọkụ osisi, ịkpọnwụ akpọnwụ, uto na-adịghị mma, mgbanwe akwụkwọ, akwụkwọ na-ada ada, okooko osisi na-ada ada, mkpụrụ osisi na-ada ada, ntozu okè, wdg, na itinye ya n'oge mkpụrụ osisi ga-emetụta uto nke mkpụrụ osisi. Ọ na-egbu egbu maka azụ ma ọ dịghị mma maka iji ya na ọdọ mmiri azụ na ugbo anụmanụ ndị ọzọ dị n'ime mmiri.
(4) Peptidamine (Mepinium): Ọ bụ ihe na-egbochi gibberellin. Ọ nwere ike ime ka mmepụta nke chlorophyll dịkwuo mma, osisi ahụ siri ike, enwere ike ịmịnye ya site na akwụkwọ na mgbọrọgwụ nke osisi ahụ, ma bufee ya na osisi ahụ dum, si otú a na-egbochi ogologo mkpụrụ ndụ na ikike apical, ma nwee ike ime ka internodes dị mkpụmkpụ ma mee ka ụdị osisi ahụ dị obere. Ọ nwere ike igbu oge uto ahịhịa nke osisi ahụ, gbochie osisi ahụ ito nke ọma, ma gbuo oge mkpuchi. Peptamine nwere ike ime ka akpụkpọ ahụ sel dịkwuo mma ma mee ka iguzogide nrụgide osisi dịkwuo elu. Ma e jiri ya tụnyere paclobutrazol na uniconazole, ọ nwere ihe ndị dị nro na ọgwụ, ọ naghị akpasu iwe, yana nchekwa dị elu. Enwere ike itinye ya n'ọrụ n'oge niile nke ihe ubi, ọbụlagodi n'oge mkpụrụ osisi na okooko osisi mgbe ihe ọkụkụ na-enwe mmetụta dị ukwuu na ọgwụ. , na n'ụzọ bụ isi ọ nweghị mmetụta ọjọọ.
(5) Chlormetrodin: Ọ na-eme ka ọrụ nke ukwuu sikwuo ike site n'igbochi mmepụta nke gibberellin dị n'ime ahụ. Chlormetrodin nwere mmetụta na-achịkwa uto osisi, na-ahazi uto ahịhịa na uto ọmụmụ, na-eme ka pollination na ọnụego ntọala mkpụrụ osisi ka mma, ma na-eme ka ịkọ ihe dị irè dịkwuo mma. Na-ebelata ogologo mkpụrụ ndụ, osisi dwarf, ogwe siri ike, ma na-ebelata internodes.
N'adịghị ka paclobutrazol na mepiperonium, a na-ejikarị paclobutrazol eme ihe n'oge mkpụrụ osisi na oge opupu ihe ubi ọhụrụ, ọ na-enwekwa mmetụta dị mma na ahụekere, mana mmetụta ya na ihe ubi oge mgbụsị akwụkwọ na oyi bụ ihe a na-ahụkarị; N'ihe ọkụkụ dị mkpụmkpụ, ojiji chlormethalin na-ezighi ezi na-emekarị ka ihe ubi ghara ịdị mma, ọ na-esikwa ike iwepụ nsị phytotoxicity; mepiperinium dị obere, enwere ike iwepụ ya site na ịgbasa gibberellin ma ọ bụ ịgbara ya mmiri iji mee ka ọmụmụ dịkwuo mma mgbe nsị phytotoxicity gasịrị.
