Muaj nuj nqi

(I) Txhawb nqa qia elongation kev loj hlob
Gibberellic acid qhov tseem ceeb tshaj plaws ntawm lub cev muaj zog yog txhawb kev loj hlob ntawm cov nroj tsuag, feem ntau nws tuaj yeem txhawb nqa cell elongation.Gibberellic acid txhawb kev loj hlob thiab muaj cov yam ntxwv hauv qab no:

1.Gibberellic acid cuam tshuam tag nrho cov nroj tsuag kev loj hlob, nws txhawb txoj kev loj hlob ntawm cov nroj tsuag stems, tshwj xeeb tshaj yog ntau yam ntawm dwarf mutant nyhuv yog qhov tseeb.Tab sis gibberellic acid elongation hauv vitro qia ntu tsis muaj lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev loj hlob ntawm me me thiab IAA ntawm tag nrho cov nroj tsuag, tab sis tom qab ntawd txiav tawm stems elongate lub cev muaj lub luag haujlwm tseem ceeb hauv kev txhawb nqa.Gibberellic acid los txhawb lub elongation ntawm cov nroj tsuag dwarf yog vim qhov chaw gibberellic acid biosynthesis thaiv cov neeg ntsias, ua rau lub cev gibberellic acid cov ntsiab lus qis dua li ib txwm ntau yam ntawm sake.
2. Rau cov kauj ruam kev loj hlob, gibberellic acid feem ntau txhawb ib co internodes elongation ua ntev, es tsis yog nce tus naj npawb ntawm seem.
3. Txawm tias siab tshaj qhov zoo tshaj plaws daim ntawv thov concentration, nws kuj tsis tuaj yeem inhibition kev loj hlob, tseem qhia cov txiaj ntsig zoo tshaj plaws ntawm kev nce qib, kev nce qib ntawm auxin uas muaj qhov zoo tshaj plaws concentration nyob rau hauv cov ntaub ntawv ntawm cov nroj tsuag kev loj hlob yog ho txawv.
4. Cov nroj tsuag sib txawv thiab ntau yam ntawm gibberellic acid cov tshuaj tiv thaiv yog qhov sib txawv ntawm kev siv gibberellic acid hauv zaub (celery, lettuce, leeks), pasture, cov qoob loo xws li tshuaj yej thiab ramie, tau txais txiaj ntsig zoo.

(II) Induce flowering

Qee cov nroj tsuag siab dua paj paj txawv yog cuam tshuam los ntawm hnub ntev (photoperiod) thiab qhov kub thiab txias.Piv txwv li, rau cov nroj tsuag biennial, yuav tsum muaj qee hnub ntawm kev kho mob khaub thuas (yog vernalization) kom tawg, tab sis tsis yog lwm yam nthuav tawm bolting, flowering rosette kev loj hlob.Yog tias cov nroj tsuag no tsis muaj vernalization thov gibberellic acid, tsis yog los ntawm cov txheej txheem kub qis kuj tuaj yeem ua rau paj tawg, thiab cov nyhuv yog pom tseeb.Tsis tas li ntawd, nws tuaj yeem hloov qhov ntev-hnub induction ntawm flowering nroj tsuag nyob rau hauv ib co ntev hnub, tab sis gibberellic acid nyob rau hauv luv luv-hnub nroj tsuag paj bud sib txawv yam tsis txhawb kev sib txawv rau cov nroj tsuag paj buds twb, gibberellic acid rau nws qhib paj muaj ib tug tseem ceeb txhawb nqa.Xws li gibberellic acid tuaj yeem txhawb nqa stevia, cycads thiab Cupressaceae, Taxodiaceae paj paj.

(III) Tshav kub dormancy

Nrog 2 ~ 3μg·g gibberellic acid kho dormant qos yaj ywm tuaj yeem ua rau nws germinate sai, uas tuaj yeem ua tau raws li qhov xav tau ntawm cov qos yaj ywm loj hlob ob peb zaug hauv ib xyoos.Qhov xav tau lub teeb kom tawg cov noob xav tau qhov kub thiab txias, xws li cov noob qoob loo, haus luam yeeb, zaub basil, plum thiab txiv apples, thiab lwm yam, gibberellic acid tuaj yeem hloov lub teeb thiab kub kub kom tawg dormancy, vim tias gibberellic acid tuaj yeem ua rau α-amylase, synthesis ntawm proteases thiab lwm yam hydrolytic enzymes catalyze lub degradation ntawm noob cia khoom rau embryo loj hlob thiab kev loj hlob xav tau kev pab.Hauv kev lag luam npias kev lag luam, nrog kev kho gibberellic acid yam tsis muaj germinating barley noob germination, muaj peev xwm induce α-amylase ntau lawm, saccharification txheej txheem ceev ceev thaum lub sij hawm brewing thiab qis ua pa sprout noj, yog li txo nqi.

(IV) Txhawb kev sib txawv ntawm txiv neej

Rau dioecious flowering nroj tsuag ntawm tib hom kab mob tom qab kev kho mob nrog gibberellic acid, nce qhov feem ntawm txiv neej paj;Rau cov poj niam cov nroj tsuag dioecious nroj tsuag, xws li kev kho mob nrog gibberellic acid, kuj sau cov txiv neej.Nyob rau hauv no hwm cov nyhuv ntawm auxin thiab gibberellic acid thiab ethylene opposite.

(V) Lwm yam physiological teebmeem
Gibberellic acid kuj tseem tuaj yeem ntxiv dag zog rau cov txiaj ntsig ntawm IAA ntawm kev txhawb nqa cov khoom noj thiab txhawb nqa qee cov nroj tsuag thiab txiv hmab txiv ntoo parthenocarpy, ncua cov nplooj senescence.Tsis tas li ntawd, gibberellic acid kuj tuaj yeem txhawb kev faib tawm ntawm tes thiab sib txawv, gibberellic acid los txhawb kev faib cell yog vim qhov luv ntawm G1 thiab S theem.Tab sis gibberellic acid inhibited tsim ntawm adventitious keeb kwm tab sis uas auxin txawv.
