Masana kimiyyar kasar Japan ne suka fara gano Gibberellins a lokacin da suke nazarin shinkafa "cutar bakana".Sun gano cewa dalilin da ya sa tsire-tsiren shinkafa masu fama da cutar bakanae suka girma kuma suka yi rawaya saboda abubuwan da gibberellins ke ɓoyewa.Daga baya, wasu masu bincike sun ware wannan sinadari mai aiki daga tacewa na cibiyar al'adun Gibberella, suka gano tsarin sinadarai, suka sanya masa suna gibberellin.Ya zuwa yanzu, an gano gibberellins guda 136 masu bayyanannun sifofin sinadarai kuma an sanya musu suna GA1, GA2, GA3, da sauransu a cikin tsarin lokaci.Gibberellic acid kaɗan ne kawai a cikin tsire-tsire ke da tasirin physiological wajen daidaita haɓakar shuka, kamar GA1, GA3, GA4, GA7, da sauransu.
Yankin girma na tsire-tsire shine babban wurin haɗin gibberellins.Gibberellins suna aiki a kusa bayan an haɗa su.Yawan abun ciki na gibberellin zai shafi yawan amfanin ƙasa da ingancin shuke-shuke.A zamanin yau, yawancin "anti-gibberellin" tsire-tsire masu ci gaba da haɓaka sun samo asali ne bisa la'akari da halayen roba na gibberellins, musamman ciki har da: chlormequat, mepifenidium, paclobutrazol, uniconazole, da dai sauransu.
Babban ayyukan gibberellins sune:
1. Inganta iri germination: Gibberellin iya yadda ya kamata karya dormant jihar shuka tsaba, tubers, buds, da dai sauransu da kuma inganta germination.
2. Tsarin tsayin tsire-tsire da girman gabobin jiki: Gibberellin ba zai iya haɓaka haɓakar ƙwayoyin shuka kawai ba amma kuma yana haɓaka rarraba tantanin halitta, ta haka yana daidaita tsayin shuka da girman gabobin.
3.
