Txhua tus paub gibberellins yog diterpenoid acids uas yog synthesized los ntawm txoj kev terpenoid hauv plastids thiab tom qab ntawd hloov pauv hauv endoplasmic reticulum thiab cytosol txog thaum lawv mus txog lawv daim ntawv bio-active.

Yog li ntawd, gibberellins ua li cas?

Tshuaj hais lus, gibberellins yog cov kua qaub. Lawv yog tsim tawm hauv cov xovtooj ntawm tes plastids, lossis ob lub membrane-bound organelles lub luag haujlwm ua zaub mov noj, thiab thaum kawg tau pauv mus rau qhov kawg ntawm cov hlab ntshav ntawm tes, qhov uas lawv tau hloov kho thiab npaj rau siv.

Ib tug kuj yuav nug, dab tsi yog qhov precursor ntawm gibberellin? Precursor ntawm Gibberellin - yog geranyl geranyl diphosphate. Auxin yog tryptophan amino acid. Ethylene yog aminocyclopropane 1-carboxylic acid (ACC)

Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog qhov tseem ceeb tshaj plaws kev lag luam daim ntawv thov ntawm gibberellins?

Kev Siv Lag Luam # 1. Gibberellins qee zaum siv los txhawm rau nce qib ntawm -amylase hauv cov noob qoob loo (Hordeum vulgare) uas yog siv hauv kev tsim cov malt rau kev lag luam brewing.

Dab tsi yog qhov txawv ntawm auxin thiab gibberellin?

Lub ntsiab qhov sib txawv ntawm auxin thiab gibberellin yog lub auxin ua txhawb kev loj hlob ntawm cov txheej txheem tua qhov gibberellin ua txhawb nqa elongation, germination, thiab flowering. Tsis tas li ntawd, auxin ua ua lub luag haujlwm hauv apical dominance whereas gibberellin tsis muaj lub luag haujlwm hauv apical dominance.
