Asingabantu kuphela kwezinto eziphilayo ezivelisa iihomoni. Kwakhona izilwanyana kunye nezityalo zinako ukukwazi. Enye yezona hormone zidumileyo nezisetyenziswa ngokubanzi yi-ethylene, izicelo zazo ezahlukeneyo.
Ukuba ufuna ukwazi ngakumbi ngale hormone yesityalo, ndincoma ukuba uqhubeke ufunda eli nqaku. Siza kuthetha malunga nokuba yintoni i-ethylene, yeyantoni kwaye uyifumana phi kwindalo. Ukongeza, siza kuthetha ukuba zeziphi iziqhamo ezingafanelekanga ukuba ziqokelelwe kwi-pantry yethu okanye kwifriji ngenxa ye-ethylene.
Yintoni i-ethylene kwaye yenzelwe ntoni?
Zininzi iihormoni ezahlukeneyo kwaye hayi ebantwini kuphela, kodwa nakwizilwanyana nakwizityalo. Umzekelo, i-Ethylene, umzekelo, yincindi yesityalo ngohlobo lwegesi. Injongo yayo kukuba lawula iinkqubo ezinxulumene ne-senescence kunye nokuvuthwa zombini iintyatyambo kunye neziqhamo kunye nemifuno. Ke ngoko, ikwabizwa ngokuba sisityalo sokuguga kwesityalo.
Xa le gesi isakha, le mifuno ivuthwa ngokukhawuleza, ephela ibangela ilahleko esemgangathweni kunye nokuhla kobomi bayo obuluncedo. Ukongeza, kukho izifo ezithile zasimahla ezisemoyeni ezinokuchaphazela nomgangatho weentyatyambo, iziqhamo kunye nemifuno, kwaye oko kunyusa ukwanda kwazo xa kukho i-ethylene kwimeko-bume. Ngale ndlela, izicwili zezityalo ezinokonakala ziyawohloka.
Ngokumalunga nokusetyenziswa kwe-ethylene, zininzi izinto ezisetyenziswayo kule hormone. Ngokuqhelekileyo isetyenziselwa iiplastiki, iingubo, i-solvents kunye ne-antifreeze. Ukusetyenziswa okunikwe ngokusisiseko kuxhomekeke kwikhompawundi. Makhe sibone eminye imizekelo:
- Polyvinylchloride: Umbane weendonga, imigangatho, imibhobho, iitanki, njl.
- Polyethylene: Iityhubhu, imibhobho, idreyini, izikhongozeli, iinxalenye ze-thermoformed, insulation, njl. Yinto enqabileyo kwaye iguquguqukayo.
- IPolytrafrafluoroethene: Iigaskethi, i-bushings, i-cookware liners. Ikwabizwa ngokuba yiTeflon.
- Polyacrylonitrile: Ukuveliswa kwemicu yelaphu. Yomelele kwaye kulula ukuyidaya ikhompawundi enokuphothwa.
- I-ethylene oxide: Iikhemikhali eziphakathi ekuveliseni ii-non-ionic detergents, i-ethylene glycol, i-polyethylene glycols kunye nezinye zazo. Ikwasetyenziswa njengesiqhumisi. Lulwelo olungenambala, lunokutsha kwaye luhamba okanye igesi.
Ifumaneka phi i-ethylene kwindalo?
Njengoko besitshilo ngaphambili, i-ethylene yihomoni eveliswa zizityalo. Iintyatyambo, iziqhamo kunye nemifuno zizinto eziphilayo eziqhubeka ukuphefumla nasemva kokuvuna. Xa bephefumla, abavelisi kuphela i-carbon dioxide (CO2) kunye namanzi (H2O), kodwa kunye ne-ethylene (C2H4).
Ngokubhekisele kwiziqhamo kunye nemifuno, iziphumo ezilungileyo ze-ethylene ziyahluka. Ngexesha lokuqala lokuphuhliswa kweziqhamo kunye nemifuno, banemixube enetyhefu ethi inyamalale xa ivuthwa. Ke ngoko, ngenxa ye-ethylene ziyatyiwa. Ukongeza, ithambisa ubume bayo. Amanqanaba esitatshi kunye neasidi ayancitshiswa, ngelixa inqanaba leswekile liyanda. Ngale ndlela iziqhamo kunye nemifuno iba tastier. Elinye inqaku ekufuneka uliqaphele kukuba le hormone iphucula umbala wolusu kunye nevumba abalikhuphelayo.
Nangona kunjalo, emva kokuqokelela iziqhamo kunye nemifuno kwindawo efanelekileyo yokuvuthwa kwentengiso, Zonke ezi ziphumo ziluncedo ze-ethylene azisekho. Xa iziqhamo zifikelele kwinqanaba lokuvuthwa, ziyaqhubeka nokuvelisa le hormone, ethi iphele ibangela ukuba baluphale de babole.
Zeziphi iziqhamo ekungafanelekanga ukuba ziqokelelwe?
Ukuba yirhasi, i-ethylene ihlala kwindalo esingqongileyo. Kukho iziqhamo kunye nemifuno ebonakala ngokuba ngabavelisi abakhulu behomoni, ngelixa abanye bethambile kuyo. Ezi ntlobo zimbini akufuneki zidityaniswe, ukuthintela iqela lesibini ekuwohlokeni ngokukhawuleza. Xa isiqhamo esele sivuthiwe sikhupha i-ethylene, ukukhula kweziqhamo ezikufutshane kuyakhawuleza. Ngale ndlela baqala ukubola ngokukhawuleza okukhulu kunesiqhelo. Eminye imizekelo yoku iya kuba yile ilandelayo:
- Iikherothi: Bafumana incasa ekrakra.
- I-asparagus: Amagqabi ayo anyusa uburhabaxa.
- Ilethasi: Kuvela amabala abomvu.
- Ibrokholi: Iphulukana nombala.
- Utamatisi Imifuno evuthiweyo: Ziba zithambile.
- Iitapile: Ulusu lushwabene luze luqale ukubola.
Kunoko, ezinye iziqhamo kunye nemifuno zivelisa i-ethylene eninzi. Ke ngoko, akufuneki zidityaniswe nezo zikhankanywe apha ngasentla. Siza kubona ngezantsi uluhlu lweziqhamo ezivelisa eyona gesi ye-ethylene:
- I-Avocado
- I-anyanisi
- Iiplums
- Iapile
- imango
- I-Melon
- Banana
- Utamatisi
- Iidiliya
Ufunda into entsha yonke imihla. Ukuba ubungazi ukuba yintoni i-ethylene, ndiyathemba ukuba ndiwucacisile lo mbuzo. Ukongeza, kuluncedo kakhulu ukwazi ukuba zeziphi iziqhamo kunye nemifuno akufuneki zibekwe ndawonye ukuze zihlale ixesha elide zintsha kwaye zimnandi. Ngale ndlela sigcina imali encinci xa uthenga kwaye sigcina izibonelelo ezinokusizisela le mifuno ixesha elide.
