Daim Ntawv Thov / Siv / Muaj nuj nqi
Ethephon yog tib yam li ethylene. Nws tsuas yog ua kom muaj peev xwm ntawm ribonucleic acid synthesis hauv hlwb thiab txhawb nqa synthesis protein. Hauv thaj chaw sib cais ntawm cov nroj tsuag xws li lub petiole, txiv hmab txiv ntoo soj, thiab lub hauv paus petal, qhov nce ntawm synthesis protein txhawb kom rov ua haujlwm ntawm cov cellulase hauv txheej txheej cais, uas ua kom nrawm rau kev tsim cov txheej sib cais thiab ua rau lub cev ua haujlwm. Ethephon tuaj yeem txhim kho kev ua haujlwm ntawm cov enzymes thiab ua kom phosphatase thiab lwm yam enzymes ntsig txog cov txiv hmab txiv ntoo ua kua thaum lub txiv siav, thiab txhawb cov txiv hmab txiv ntoo. Hauv cov nroj tsuag muaj hnub nyoog loj lossis cov chaw muaj taus, Ethephon txhawb nqa cov tshuaj synthesis thiab ua rau muaj kev hloov pauv peroxidase.
Ethephon muaj qhov cuam tshuam ntawm kev txhawb poj niam kev sib txawv paj; txhawb cov txiv ntoo; txhawb nqa cog tsob nroj; tawg nroj tsuag dormancy.
Ethephon yog cov cog kev cog kev loj hlob ntawm tsob nroj. Nws muaj lub cev kev ua haujlwm ntawm cov tshuaj hormones cog kom nce lub tso pa tawm ntawm cov emulsions, ua kom lub cev ruaj khov, ua kom tiav sai sai, ua kom laus, thiab ua kom tawg paj. Ethylene tuaj yeem tso tawm rau hauv cov hauv paus hniav, plhaw, nplooj, qia, paj thiab txiv hmab txiv ntoo ntawm cov nroj tsuag kom tswj cov metabolism, kev loj hlob thiab kev loj hlob ntawm cov nroj tsuag. Nws tuaj yeem txhawb lub zog thaum ntxov ntawm ntau cov suab paj nruag thiab txiv hmab txiv ntoo, xws li tsawb, txiv qaub, txiv lws suav, txiv ntoo, thiab lwm yam, nws tuaj yeem txhawb kev nti ntawm roj hmab, sumac; nws tuaj yeem txhawb nqa thaum ntxov ntxov ntawm cov poj niam tub paj thiab ntau dua poj niam paj ntawm dib; nws tuaj yeem siv los ua kom nrawm nrawm ntawm paj rwb thiab haus luam yeeb, thiab tseem tuaj yeem tiv thaiv kev cog ntoo, ua kom cov nroj tsuag luv, tawg cov noob dormancy.
Siv nyob rau hauv kev tsim cov roj hmab ntuj, benzoin thiab lacquer, Ethephon muaj cov ntsiab lus tseem ceeb hauv kev nce ntau lawm. Ethephon yog siv los txhawb kev loj hlob ntawm cov paj rwb thaum ntxov, tsom rau kev nti, nce hauv tidbits, thiab txhim kho cov qhab nia, uas yog qhov txiaj ntsig rau kev tsim kho ntawm kev ua paj rwb; nws kuj tseem siv tau rau ripening ntawm tsawb thiab txiv lws suav, ripening ntawm thaum ntxov mov, yellowing ntawm haus luam yeeb nplooj, kev tswj cov txiv puv ntoo tawg paj, txiv neej hloov pauv ntawm melon paj, txiv neej kom tsis muaj menyuam ntawm hom qoob mog, thiab xim ntawm txiv apples thiab txiv kab ntxwv.
