Dab tsi yog regulating foliar chiv?
Hom foliar chiv no muaj cov tshuaj uas tswj cov nroj tsuag kev loj hlob, xws li auxin, cov tshuaj hormones thiab lwm yam khoom xyaw.
Nws lub luag haujlwm tseem ceeb yog tswj cov nroj tsuag kev loj hlob thiab kev loj hlob. Nws yog haum rau siv nyob rau hauv thaum ntxov thiab nruab nrab theem ntawm cov nroj tsuag loj hlob.
Thaum lub sij hawm txoj kev loj hlob, cov nroj tsuag tsis tau tsuas yog synthesize ntau as-ham thiab structural tshuaj, tab sis kuj tsim ib co physiologically active tshuaj, hu ua endogenous cog cov tshuaj hormones. Txawm hais tias cov tshuaj hormones no muaj me me hauv cov nroj tsuag, lawv tuaj yeem tswj thiab tswj kev loj hlob thiab kev loj hlob ntawm cov nroj tsuag, xws li kev loj hlob ntawm tes thiab kev sib txawv, kev faib tawm ntawm tes, kev tsim khoom hauv nruab nrog cev, dormancy thiab germination, cog tropism, rhiab heev, kev loj hlob, shedding, kev laus, thiab lwm yam, tag nrho cov uas ncaj qha los yog tsis ncaj ncees tswj los ntawm cov tshuaj hormones. Qee cov khoom siv hluav taws xob tsim hluav taws xob hauv cov chaw tsim khoom uas muaj cov qauv molecular zoo sib xws thiab cov teebmeem physiological rau cov tshuaj hormones ntuj hu ua cog kev loj hlob regulators.
Cov nroj tsuag kev loj hlob regulators thiab cov nroj tsuag cov tshuaj hormones feem ntau yog ua ke hu ua cog kev loj hlob regulators.
Tam sim no, feem ntau siv cog kev loj hlob regulators nyob rau hauv ntau lawm
① Auxin:xws li Naphthalene acetic acid (NAA), Indole-3-acetic acid, anti-poob agent, 2,4-D, thiab lwm yam.;
② Gibberellik Acid:Muaj ntau hom Gibberellic Acid tebchaw, tab sis Gibberellic Acid siv hauv kev tsim khoom yog feem ntau (GA3) thiab GA4, GA7, thiab lwm yam;
③Cytokinins:ua 5406;.
④ Ethylene:Ethephon;
⑤Cov tshuaj tiv thaiv kev loj hlob los yog retardants:Chlormequat Chloride (CCC), chlorambucil, Paclobutrazol (Paclo), yas, thiab lwm yam. Ntxiv rau cov saum toj no, muaj Brassinolide (BRs), zeati, abscisic acid, defoliants, triacontanol, thiab lwm yam.
