I-Allantoin, inhlanganisela yemvelo etholakala ezitshalweni nasezilwaneni, iye yazuza ukunakwa ngenxa yokusebenza kwayo okungenzeka kwezolimo.Ukuba nokwenzeka kwayo njengomkhiqizo wezolimo kusemandleni ayo okuthuthukisa isivuno sezitshalo ngezindlela ezihlukahlukene.
Okokuqala, i-allantoin isebenza njenge-biostimulant yemvelo, ethuthukisa ukukhula nokuthuthuka kwezitshalo.Ivuselela ukuhlukana kwamangqamuzana nokwelula, okuholela ekwandeni kwezimpande nokukhula kwamahlumela.Lokhu kukhuthaza izitshalo ezinamandla nezinempilo, ezihlomele kangcono ukumunca imisoco namanzi emhlabathini.Ukwengeza, i-allantoin ithuthukisa ukusebenza kahle kokuthatha izakhi ngokuthuthukisa umsebenzi wama-enzyme ahlobene nezimpande anesibopho sokumuncwa kwezakhi, njenge-phosphatase kanye ne-nitrate reductase.
Okwesibili,i-allantoinizinsiza ekubekezeleleni ukucindezeleka kanye nokuvikelwa ezinseleleni zemvelo.Isebenza njenge-osmolyte, elawula ibhalansi yamanzi ngaphakathi kwamangqamuzana ezitshalo futhi inciphise ukulahlekelwa kwamanzi phakathi nezimo zesomiso.Lokhu kusiza izitshalo ukuthi zigcine i-turgidity kanye nokusebenza komzimba jikelele ngisho nangaphansi kwezimo zokuntuleka kwamanzi.I-Allantoin futhi isebenza njenge-antioxidant, ikhipha ama-radicals mahhala futhi ivikele izitshalo ekucindezelekeni kwe-oxidative okubangelwa izici ezifana nemisebe ye-UV kanye nokungcola.
Ngaphezu kwalokho, i-allantoin idlala indima ekugayweni kabusha kwezakhi kanye ne-nitrogen metabolism.Ibandakanyeka ekuqhekekeni kwe-uric acid, umkhiqizo wemfucuza ye-nitrogen, ibe yi-allantoin.Lokhu kuguqulwa kuvumela izitshalo ukuthi zisebenzise i-nitrogen ngokuphumelelayo, okunciphisa isidingo sokufakwa kwe-nitrogen yangaphandle.Ngokuthuthukisa i-nitrogen metabolism, i-allantoin inomthelela ekukhuleni kwezitshalo okuthuthukisiwe, ukwakheka kwe-chlorophyll, nokukhiqizwa kwamaprotheni.
Ngaphezu kwalokho, i-allantoin itholakale ikhuthaza ukusebenzisana okuzuzisayo phakathi kwezitshalo nama-microorganisms anenzuzo emhlabathini.Isebenza njenge-chemoattractant ye-bacteria yomhlabathi enenzuzo, ikhuthaza ukuhlangana kwawo ezimpandeni zezitshalo.Lawa mabhaktheriya angasiza ekutholeni izakhi, alungise i-nitrogen yasemkhathini, futhi avikele izitshalo kumagciwane.Ubudlelwano be-symbiotic phakathi kwezitshalo nama-microorganisms azuzisayo enhlabathini athuthukiswa i-allantoin bungaholela ekwenzeni ngcono impilo yezitshalo kanye nokukhiqiza.
Sengiphetha, ukusetshenziswa kwei-allantoinkwezolimo kunesithembiso esibalulekile sokuthuthukisa isivuno sezitshalo.Izici zayo ze-biostimulant, ukuthuthukiswa kokubekezelela ingcindezi, ukubandakanyeka ekugayweni kabusha kwezakhi, kanye nokwenza lula amagciwane anenzuzo konke kunomthelela ekukhuleni kwezitshalo okuthuthukisiwe, ukukhula, kanye nokukhiqiza kukonke.Ucwaningo olwengeziwe nezivivinyo zasensimini zibalulekile ukuze kutholwe izindlela ezilungile zokufaka isicelo, umthamo, nezimpendulo zezitshalo ezithile, kodwa i-allantoin ibonisa amandla amakhulu njengethuluzi elibalulekile kwezolimo ezisimeme.
