I-Gibberellins yatholwa okokuqala ososayensi baseJapane lapho befunda irayisi "isifo se-bakanae".Bathola ukuthi isizathu esenza izitshalo zelayisi eziphethwe yi-bakanae zikhule zaba zinde futhi zaba phuzi kungenxa yezinto ezikhiqizwe ama-gibberellins.Kamuva, abanye abacwaningi bahlukanisa le nto esebenzayo kusihlungi se-Gibberella Culture medium, bahlonza ukwakheka kwamakhemikhali ayo, base beyiqamba ngokuthi i-gibberellin.Kuze kube manje, ama-gibberellin angu-136 anezakhiwo zamakhemikhali acacile akhonjiwe futhi aqanjwa ngokuthi GA1, GA2, GA3, njll. ngokulandelana kwesikhathi.Ama-Gibberellic acid ambalwa kuphela ezitshalweni anemiphumela yomzimba ekulawuleni ukukhula kwezitshalo, njenge-GA1, GA3, GA4, GA7, njll.

Indawo ekhula ngokushesha yezitshalo iyindawo eyinhloko yokuhlanganiswa kwe-gibberellins.Ama-Gibberellins asebenza eduze ngemva kokuhlanganiswa kwawo.Okuqukethwe kwe-gibberellin okuningi kuzothinta isivuno kanye nekhwalithi yezitshalo.Kulezi zinsuku, i-anti-gibberellin eminingi yokukhula kwezitshalo iye yathuthukiswa ngokusekelwe ezicini zokwenziwa ze-gibberellins, ikakhulukazi ezihlanganisa: i-chlormequat, i-mepifenidium, i-paclobutrazol, i-uniconazole, njll.

  

Imisebenzi eyinhloko ye-gibberellins yilezi:
1. Khuthaza ukuhluma kwembewu: I-Gibberellin inganqamula ngokuphumelelayo isimo sokungalali sembewu yezitshalo, izigaxa, imiqumbe, njll. futhi ikhuthaze ukuhluma.
2. Ukulawulwa kobude bezitshalo nosayizi wesitho: I-Gibberellin ayikwazi nje ukukhuthaza ukukhula kwamangqamuzana ezitshalo kodwa futhi ikhuthaze ukuhlukana kwamaseli, ngaleyo ndlela ilawula ukuphakama kwesitshalo nosayizi wesitho.
3. Khuthaza ukuqhakaza kwezitshalo: Ukwelashwa ngama-gibberellins kungabangela izitshalo ezineminyaka emibili ubudala ezingakavunwa lapho izinga lokushisa eliphansi (njengesithombo, iklabishi laseShayina, izaqathi, njll.) ziqhakaze kulo nyaka.Kwezinye izitshalo ezingaqhakaza ngaphansi kwezinsuku ezinde, i-gibberellin ingaphinde ithathe indawo yezinsuku ezinde ukuze ziqhakaze ngaphansi kwezinsuku ezimfushane.
4. I-Gibberellin ingabuye ikhuthaze ukukhula kwezithelo zezitshalo, ikhulise izinga lokumisa izithelo noma yakhe izithelo ezingenambewu.
5. I-Gibberellins nayo inomthelela ekuthuthukisweni kwembali kanye nokuzimisela kobulili.Ezitshalweni ze-dioecious, uma ziphathwa nge-gibberellin, ingxenye yezimbali zesilisa izokhula;ezitshalweni zesifazane zezitshalo ze-dioecious, uma ziphathwa nge-Gibberellic acid, izimbali zesilisa zingangeniswa.

Izinyathelo zokuzivikela
(1) Uma i-gibberellin isetshenziswa njenge-ejenti yokubeka izithelo, kufanele isetshenziswe ngaphansi kwezimo zamanzi anele nomanyolo;uma isetshenziswa njengomgqugquzeli wokukhula, kufanele isetshenziswe ngokuhambisana nomanyolo we-foliar ukuze kube lula ukwakheka kwezithombo eziqinile.
(2) I-Gibberellin kulula ukubola lapho ivezwe ku-alkali.Gwema ukuxubana nezinto ezine-alkali uma uzisebenzisa.
(3) Ngenxa yokuthi i-gibberellin izwela ukukhanya nezinga lokushisa, imithombo yokushisa kufanele igwenywe lapho uyisebenzisa, futhi ikhambi kufanele lilungiswe futhi lisetshenziswe ngokushesha.
(4) Ngemva kokwelashwa kwe-gibberellin, inani lembewu engavundile liyakhula, ngakho akufanele lisetshenziswe emasimini okulima.
