Incazelo

I-Gibberellic acid (GA3) iyi-hormone ye-qhose enamandla kakhulu ezenzeka ezitshalweni ezilawula ukukhula kwazo.Ingasiza izitshalo ukuthi zinqobe ukungalali kahle, ikhuthaze ukuhluma kwezitshalo nokuqhakaza ngaphambi kwesikhathi, ikhuthaze futhi isheshise ukukhula kwezitshalo, ivimbele ukuwa kwezithelo, isize ukukhula kwezithelo ezingenambewu, ikhuthaze ukuqhakaza kwezitshalo zosuku olude ngesikhathi esifushane.I-Gibberellic acid ingathinta ngokuphephile ekukhuleni kwesiqu nezimpande zezithelo, imifino kanye nezitshalo zamaqabunga.

Umsebenzi

(I) Khuthaza ukukhula kobude besiqu
I-Gibberellic acid umphumela obaluleke kakhulu wokuphila ukukhuthaza ukukhula kwezitshalo, ikakhulukazi ingakhuthaza ukwelulwa kwamaseli.I-Gibberellic acid ikhuthaza ukukhula futhi inezici ezilandelayo:

1.I-Gibberellic acid isebenzisana nokukhula kwezitshalo zonke, ikhuthaza kakhulu ukukhula kweziqu zezitshalo, ikakhulukazi izinhlobonhlobo zomphumela omncane oguquguqukayo ubonakala ikakhulukazi.Kodwa i-gibberellic acid elongation in vitro stem segment ayinayo indima ebalulekile ekukhuthazeni ukukhula kwencane kanye ne-IAA kuso sonke isitshalo, kodwa bese kunqunywa iziqu umzimba obude unendima ebalulekile ekukhuthazeni.I-Gibberellic acid ukuze ikhuthaze ukukhula kwezitshalo ezincane kungenxa yomthombo we-gibberellic acid biosynthesis evimbe uhlobo oluncane, okwenza okuqukethwe kwe-gibberellic acid emzimbeni kube ngaphansi kunezinhlobo ezivamile ze-sake.
2. Ekukhuleni kwesinyathelo, i-gibberellic acid ikhuthaza ngokuyinhloko ukuthi ubude be-internode bube yinde, kunokwandisa inani lezigaba.
3. Iphakeme nakakhulu kunokugxilwa kwesicelo esingcono kakhulu, futhi ayikwazi ukuvimbela ukukhula, isabonisa umthelela omkhulu kakhulu wokuphromotha, ukukhuthazwa kwe-auxin enokugxila okuphezulu esimweni sokukhula kwesitshalo kuhluke kakhulu.
4. Izinhlobo ezahlukene zezitshalo nezinhlobonhlobo ze-gibberellic acid reaction zihluke kakhulu ekusetshenzisweni kwe-gibberellic acid emifino (isilimo esidliwayo esinamagatsha anamanzi, ulethisi, ama-leeks), amadlelo, izitshalo ezifana netiye ne-ramie, thola isivuno esikhulu.

(II) Dala ukuqhakaza

Ezinye izitshalo eziphakeme zokuhlukaniswa kwezimbali zithintwa ubude bosuku (i-photoperiod) kanye nemiphumela yezinga lokushisa.Isibonelo, isitshalo esihlala iminyaka emibili, sidinga inani elithile lezinsuku zokwelashwa okubandayo (i-vernalization) ukuze siqhakaze, kodwa hhayi ngenye indlela ukukhombisa ukukhula kwe-bolting, ukuqhakaza kwe-rosette.Uma lezi zitshalo ngaphandle vernalization besebenzisa gibberellic acid, hhayi by lokushisa eliphansi inqubo futhi uyakwazi ukuheha izimbali, futhi umphumela usobala.Ngaphezu kwalokho, kungathatha indawo yosuku olude lokungeniswa kwezitshalo eziqhakazayo ezinsukwini ezithile ezinde, kodwa i-gibberellic acid ezitshalweni zosuku olufushane ukuhlukaniswa kwezimbali zezimbali ngaphandle kokukhuthaza ukuhlukaniswa kwezimbali zezitshalo kakade, i-gibberellic acid embalini yayo evulekile inomphumela obalulekile wokukhuthaza.Njenge-gibberellic acid ingakhuthaza i-stevia, i-cycads ne-Cupressaceae, izitshalo zezimbali ze-Taxodiaceae.

(III) Ikhefu le-dormancy

Nge-2 ~ 3μg · g ukwelashwa kwe-gibberellic acid amazambane alele angenza ukuthi aqhume ngokushesha, angahlangabezana nezidingo zamazambane akhulayo izikhathi eziningana ngonyaka.Isidingo sokukhanya sokuhluma imbewu sidinga amazinga okushisa aphansi, njengembewu ye-ulethisi, ugwayi, i-basil, iplamu kanye ne-apula, njll., i-gibberellic acid ingangena esikhundleni sokukhanya namazinga okushisa aphansi ukuze iphule i-dormancy, kungenxa yokuthi i-gibberellic acid ingabangela i-α-amylase, ukuhlanganiswa kwama-proteases namanye ama-enzyme e-hydrolytic adala ukuwohloka kwezinto ezigcina imbewu ukuze kukhule umbungu kanye nezidingo zokuthuthuka.Embonini yokukhiqiza ubhiya, ngokwelashwa kwe-gibberellic acid ngaphandle kokuhluma kwembewu yebhali, kungadala ukukhiqizwa kwe-α-amylase, inqubo ye-saccharification isheshiswe ngesikhathi sokuphiswa kanye nokusetshenziswa kwehlumela eliphansi lokuphefumula, ngaleyo ndlela kunciphise izindleko.

(IV) Khuthaza ukuhlukaniswa kwabesilisa

Ezitshalweni zezimbali ze-dioecious zohlobo olufanayo ngemuva kokwelashwa nge-gibberellic acid, okwandisa ingxenye yezimbali zesilisa;Ezitshalweni zesifazane izitshalo ze-dioecious, ezifana nokwelashwa nge-gibberellic acid, nazo zinquma owesilisa.Kulokhu umphumela we-auxin ne-gibberellic acid ne-ethylene ngokuphambene.

(V) Eminye imiphumela yomzimba
I-Gibberellic acid ingaphinda iqinise umphumela we-IAA ekuhlanganiseni izakhi kanye nokukhuthaza izitshalo ezithile nezithelo ze-parthenocarpy, ukubambezeleka kokuvela kwamaqabunga.Ngaphezu kwalokho, i-gibberellic acid nayo ingakhuthaza ukuhlukaniswa kwamaseli nokuhlukaniswa, i-gibberellic acid ukukhuthaza ukuhlukana kwamaseli kungenxa yokufinyezwa kwesigaba se-G1 ne-S.Kodwa i-gibberellic acid ivimbele ukwakheka kwezimpande ezifikayo kodwa iziphi i-auxin ehlukile.
