Auxins txhawb nqa qia elongation, inhibit kev loj hlob ntawm lateral buds (tswj apical dominance). Lawv tsim nyob rau hauv qia, buds, thiab cov lus qhia hauv paus. Piv txwv li: Indole Acetic Acid (IA). Auxin yog cov tshuaj hormones cog uas tsim nyob rau hauv qia taub hau uas txhawb nqa cell elongation.

Ua li no, puas yog ethylene ib qho kev loj hlob inhibitor?

Lwm tus Kev loj hlob inhibitor yog ethylene , uas yog ib yam khoom ntawm cov nroj tsuag, tsim tau los ntawm linolenic acid (ib fatty acid) los yog los ntawm methionine (ib qho amino acid). Nws cov teebmeem tshwm sim dhau qhov ntawd inhibiting kev loj hlob ; nyob rau hauv txiv hmab txiv ntoo, piv txwv li, ethylene yog suav hais tias yog ib tug ripening hormone.

Tsis tas li ntawd, dab tsi yog 5 cov kev cai cog qoob loo? Feem ntau, muaj tsib hom ntawm cog Cov tshuaj hormones xws li auxin, gibberellins (GAs), cytokinins, abscisic acid (ABA) thiab ethylene. Ntxiv rau cov no, muaj ntau cov derivative compounds, ob qho tib si ntuj thiab hluavtaws, uas kuj ua raws li cog kev loj hlob regulators.

Ib yam li ntawd, nws raug nug, dab tsi yog 5 hom tshuaj hormones cog?

Qhov twg yog cov tshuaj hormones cog?

cog tshuaj hormones . Ib yam ntawm ntau yam tshuaj hormones tsim los ntawm nroj tsuag uas tswj los yog tswj germination, kev loj hlob, metabolism, los yog lwm yam physiological kev ua ub no. Auxins, cytokinins, gibberellins, thiab abscisic acid yog cov piv txwv ntawm cov tshuaj hormones cog.
