Kev sib xyaw ntawm cov nroj tsuag kev loj hlob regulators thiab fungicides nyob ntawm seb lub mechanism ntawm kev txiav txim ntawm cov neeg ua hauj, systemic conductivity, complementarity ntawm cov khoom ntawm kev tswj, thiab seb antagonism yuav tshwm sim tom qab sib tov. Qee qhov xwm txheej, xws li ua tiav lub hom phiaj ntawm kev tiv thaiv kab mob lossis txhim kho cov kab mob tiv thaiv kab mob, txhawb kev loj hlob ntawm tsob ntoo lossis cog qoob loo kom muaj zog.

Naphthalene acetic acid (NAA) yog auxin cog regulator. Nws nkag mus rau hauv cov nroj tsuag lub cev los ntawm nplooj, kev sib tw epidermis thiab cov noob, thiab yog thauj mus rau qhov chaw uas muaj zog loj hlob (cov ntsiab lus loj hlob, cov tub ntxhais hluas lub cev, paj los yog txiv hmab txiv ntoo) nrog as-ham txaus, ho txhawb txoj kev loj hlob ntawm lub hauv paus system (rooting hmoov) , inducing flowering, tiv thaiv poob paj thiab txiv hmab txiv ntoo, tsim seedless txiv hmab txiv ntoo, txhawb kev loj hlob thaum ntxov, nce ntau lawm, thiab lwm yam. Nws kuj yuav txhim khu cov nroj tsuag muaj peev xwm tiv taus drought, txias, kab mob, ntsev thiab alkali, thiab qhuav cua kub.

Indole-3-butyric acid (IBA) yog cov tshuaj tiv thaiv kev loj hlob ntawm cov nroj tsuag uas tuaj yeem txhawb cov nroj tsuag kev loj hlob thiab kev loj hlob, ua rau cov nroj tsuag muaj kev nplua nuj thiab muaj zog, thiab txhim kho cov nroj tsuag kev tiv thaiv thiab kev ntxhov siab.

Brassinolide (BRs) yog cov nroj tsuag kev loj hlob zoo regulator siv los txo cov tshuaj tua kab puas tsuaj. Brassinolide (BRs) tuaj yeem pab cov qoob loo rov zoo li qub, txhim kho cov khoom ua liaj ua teb sai thiab ua kom cov qoob loo nce ntxiv, tshwj xeeb tshaj yog hauv kev txo cov tshuaj tua kab mob. Nws tuaj yeem ua kom cov synthesis ntawm cov amino acids hauv lub cev, ua rau cov amino acids poob vim kev puas tsuaj rau cov tshuaj tua kab, thiab ua tau raws li cov kev xav tau ntawm cov qoob loo loj hlob, yog li txo cov tshuaj tua kab.
