Ndị ọkà mmụta sayensị Japan chọtara Gibberellins mgbe ha na-agụ osikapa "ọrịa bakanae".Ha chọpụtara na ihe mere osisi osikapa na-arịa ọrịa bakanae ji to ogologo ma na-acha odo odo bụ n'ihi ihe ndị gibberellins zoro ezo.Mgbe e mesịrị, ụfọdụ ndị nchọpụta wepụrụ ihe a na-arụ ọrụ na nzacha nke usoro omenala Gibberella, chọpụta nhazi kemịkal ya, ma kpọọ ya gibberellin.Ka ọ dị ugbu a, a chọpụtala gibberellin 136 nwere kemịkalụ doro anya wee kpọọ GA1, GA2, GA3, wdg n'usoro oge.Naanị Gibberellic acid ole na ole n'ime osisi nwere mmetụta physiological n'ịchịkwa uto osisi, dị ka GA1, GA3, GA4, GA7, wdg.
Mpaghara uto ngwa ngwa nke osisi bụ isi saịtị maka njikọ nke gibberellins.Gibberellins na-eme ihe nso ka emechara ha.Nnukwu ọdịnaya gibberellin ga-emetụta mkpụrụ na ogo osisi.N'oge a, a na-emepụta ọtụtụ "anti-gibberellin" osisi retardants na-adabere na njirimara sịntetik nke gibberellins, nke gụnyere: chlormequat, mepifenidium, paclobutrasol, uniconazole, wdg.
Isi ọrụ nke gibberellins bụ:
1. Na-akwalite mkpụrụ germination: Gibberellin nwere ike n'ụzọ dị irè agbaji dormant ala osisi osisi, tubers, buds, wdg ma kwalite germination.
2. Iwu nke osisi elu na akụkụ size: Gibberellin nwere ike ọ bụghị nanị na-akwalite osisi elongation cell kamakwa na-akwalite cell nkewa, si otú na-achịkwa osisi elu na akụkụ size.
3. Kwalite okooko osisi: Ọgwụgwọ na gibberellins nwere ike ime ka osisi biennial nke na-edobebeghị na obere okpomọkụ (dị ka radish, kabeeji Chinese, karọt, wdg) na-eto eto n'afọ ugbu a.Maka ụfọdụ osisi ndị nwere ike ito eto n'okpuru ogologo ụbọchị, gibberellin nwekwara ike dochie ọrụ nke ogologo ụbọchị iji mee ka ha tolite n'okpuru ụbọchị dị mkpirikpi.
4. Gibberellin nwekwara ike kpalite uto nke mkpụrụ osisi, na-abawanye ọnụego ntọala mkpụrụ osisi ma ọ bụ mepụta mkpụrụ osisi na-enweghị mkpụrụ.
5. Gibberellins nwekwara mmetụta na mmepe ifuru na mkpebi mmekọahụ.Maka osisi dioecious, ọ bụrụ na ejiri gibberellin agwọ ya, oke nke ifuru nwoke ga-abawanye;maka osisi ụmụ nwanyị nke osisi dioecious, ọ bụrụ na ejiri Gibberellic acid agwọ ya, enwere ike ịkpata ifuru nwoke.
