Daim ntawv thov
2.1 Yuav kom tau txais txiaj ntsig zoo li cas?
Ethephon yog tus tswj kev loj hlob ntawm cov nroj tsuag.Nws muaj cov teebmeem physiological ntawm kev txhim kho cov tshuaj hormones secretion, accelerating maturation, abscission, senescence thiab txhawb flowering.Hauv qee qhov xwm txheej, ethephon tsis tuaj yeem tso tawm ethylene nws tus kheej xwb, tab sis kuj txhawb cov nroj tsuag los tsim ethylene.
2.2 Yuav siv li cas rau cov qoob loo?
Cucumbers, zucchini, taub dag, txiv lws suav, dib, thiab lwm yam.
2.3 Dosage thiab siv

3.Mechanism ntawm kev ua
Ethephon, zoo li ethylene, feem ntau txhim kho lub peev xwm ntawm RNA synthesis hauv hlwb thiab txhawb nqa cov protein synthesis.Nyob rau hauv cov nroj tsuag abscission cheeb tsam, xws li petiole, txiv hmab txiv ntoo stalk thiab petal puag, cov protein ntau synthesis txhawb lub re synthesis ntawm cellulase nyob rau hauv lub abscission txheej, vim hais tias nws accelerates tus tsim ntawm abscission txheej thiab ua rau lub cev abscission.Ethephon tuaj yeem txhim kho cov haujlwm ntawm cov enzymes, qhib phosphatase thiab lwm yam enzymes cuam tshuam rau txiv hmab txiv ntoo ripening, thiab txhawb cov txiv hmab txiv ntoo ripening.Hauv cov nroj tsuag senescent lossis susceptible, peroxidase hloov pauv yog tshwm sim los ntawm Ethephon txhawb cov protein synthesis.Ethylene tuaj yeem cuam tshuam cov synthesis ntawm endogenous auxin thiab ncua kev loj hlob ntawm cov nroj tsuag.
