I-Allantoin, isakhi semvelo esitholakala ezitshalweni nasezilwaneni, sithole ukunakwa ngenxa yezindlela zaso zokusebenza ezingaba khona kwezolimo. Ukusebenziseka kwaso njengomkhiqizo wezolimo kusekukwazini kwaso ukukhuthaza isivuno sezitshalo ngezindlela ezahlukahlukene.
Okokuqala, i-allantoin isebenza njenge-biostimulant yemvelo, ithuthukisa ukukhula nokukhula kwezitshalo. Ivuselela ukuhlukana kwamaseli nokwandiswa, okuholela ekukhuleni kwezimpande namahlumela. Lokhu kukhuthaza izitshalo eziqinile nezinempilo, ezihlonyiswe kangcono ukumunca izakhamzimba namanzi avela enhlabathini. Ngaphezu kwalokho, i-allantoin ithuthukisa ukusebenza kahle kokumunca izakhamzimba ngokuthuthukisa umsebenzi wama-enzyme ahlobene nezimpande abhekene nokumunca izakhamzimba, njenge-phosphatases kanye ne-nitrate reductases.
Okwesibili,i-allantoinkusiza ekubekezeleni ukucindezeleka kanye nokuvikela izinselele zemvelo. Isebenza njenge-osmolyte, ilawula ibhalansi yamanzi ngaphakathi kwamaseli ezitshalo futhi inciphise ukulahleka kwamanzi ngesikhathi sesomiso. Lokhu kusiza izitshalo ukuthi zilondoloze ukuqina kanye nokusebenza komzimba wonke ngisho nangaphansi kwezimo zokuntuleka kwamanzi. I-Allantoin iphinde isebenze njenge-antioxidant, isusa ama-free radical ayingozi futhi ivikele izitshalo ekucindezelekeni kwe-oxidative okubangelwa yizici ezifana nemisebe ye-UV kanye nokungcola.
Ngaphezu kwalokho, i-allantoin idlala indima ekusetshenzisweni kabusha kwezakhamzimba kanye nokuguqulwa kwe-nitrogen. Ihilelekile ekuqhekekeni kwe-uric acid, umkhiqizo ongcolile we-nitrogen, ibe yi-allantoin. Lokhu kuguqulwa kuvumela izitshalo ukuthi zisebenzise i-nitrogen ngendlela ephumelela kakhulu, kunciphisa isidingo sokufakwa kwe-nitrogen yangaphandle. Ngokuthuthukisa ukuguqulwa kwe-nitrogen, i-allantoin inegalelo ekukhuleni kwezitshalo okuthuthukisiwe, ukwakheka kwe-chlorophyll, kanye nokukhiqizwa kwamaprotheni.
Ngaphezu kwalokho, i-allantoin itholakale ikhuthaza ukusebenzisana okunenzuzo phakathi kwezitshalo kanye nama-microorganism awusizo enhlabathini. Isebenza njenge-chemoattractant yama-bacteria awusizo enhlabathini, ikhuthaza ukuhlangana kwawo eduze kwezimpande zezitshalo. Lawa ma-bacteria angasiza ekutholeni izakhamzimba, alungise i-nitrogen esemkhathini, futhi avikele izitshalo emagciwaneni. Ubudlelwano bokubambisana phakathi kwezitshalo nama-microorganism awusizo enhlabathini obuthuthukiswa yi-allantoin bungaholela empilweni yezitshalo kanye nokukhiqiza okuthuthukisiwe.
Ekuphetheni, ukusetshenziswa kwei-allantoinkwezolimo kunesithembiso esikhulu sokukhuthaza isivuno sezitshalo. Izakhiwo zayo zokuvuselela umzimba, ukuthuthukiswa kokubekezelela ukucindezeleka, ukubandakanyeka ekusetshenzisweni kabusha kwezakhamzimba, kanye nokwenza kube lula ama-microorganisms awusizo konke kunegalelo ekukhuleni kwezitshalo okuthuthukisiwe, intuthuko, kanye nokukhiqiza okuphelele. Ucwaningo olwengeziwe kanye nokuhlolwa kwensimu kubalulekile ukuze kunqunywe izindlela zokusebenzisa ezifanele, umthamo, kanye nezimpendulo ezithile zezitshalo, kodwa i-allantoin ikhombisa amandla amakhulu njengethuluzi eliwusizo kwezolimo ezisimeme.
