Isithombe: Ukutheleleka Kwezimpukane Zommbila Endlebeni Yommbila
Kushicilelwe: Mashi 16, 2026 22:44:03 UTC
Isithombe esiseduze esinekhwalithi ephezulu sesitshalo sommbila esinegciwane le-corn smut (Ustilago maydis), esibonisa izinyongo ezimpunga ezivuvukele kanye nezinhlayiya ezimnyama ezithatha indawo yezimbewu endlebeni yommbila.

Izinguqulo ezitholakalayo zalesi sithombe
Amafayela ezithombe atholakalayo ukuze alandwe ngezansi awacindezelwe kakhulu futhi anesisombululo esiphezulu - futhi ngenxa yalokho, ikhwalithi ephezulu - kunezithombe ezifakwe ezihlokweni nasemakhasini akule webhusayithi, ezilungiselelwe kangcono usayizi wefayela ukuze kuncishiswe ukusetshenziswa komkhawulokudonsa.

Incazelo yesithombe
Lesi sithombe sendawo esinekhwalithi ephezulu sibonisa umbono oseduze wesitshalo sommbila esibonakala singenwe yi-corn smut, isifo se-fungus esibangelwa yi-Ustilago maydis. Iphuzu elibalulekile lesithombe yindlebe yommbila evuleke kancane lapho imigqa evamile yezinhlayiya eziphuzi ithathelwe indawo yizinhlayiya ze-fungus ezivuvukile, ezingamile ngendlela engavamile. Lezi zakhiwo ezinamagagasi zibonakala zimpunga-mhlophe kuya kwesiliva elikhanyayo ngombala futhi ziyahlukahluka ngobukhulu, zakha inqwaba ehlanganisiwe egcwalisa ingaphakathi le-husk. Izinhlayiya eziningana zibonisa izindawo ezimnyama, ezinamabala lapho ulwelwesi lwangaphandle seluqale ukuqhekeka, okuveza ama-spores amnyama, ayimpuphu alesi sifo.
Amaqabunga e-husk azungeze indlebe adonswa kancane emuva, eveza izicubu ezithelelekile. Abonakala eluhlaza okotshani anemigqa emincane kanye nokugoba kwemvelo, ehlela indlebe enesifo futhi eqondisa ukunaka kombukeli enkabeni yesithombe. Imicu emincane yesilika yommbila iphuma phezulu kwendlebe, ihlangene phakathi kokukhula kwesikhunta. Imicu yesilika yomile futhi insundu, okubonisa isigaba sakamuva sokuthuthuka esitshalweni sommbila kanye nokuqhubeka kokutheleleka.
Kuwo wonke ama-gall, amabala amnyama namabala amnyama e-spore mass adala umehluko omkhulu ngokumelene nolwelwesi lwangaphandle olumpunga olukhanyayo. Amanye ama-gall abushelelezi futhi aphelele, kanti amanye abonisa ukuqhekeka noma ukuqhekeka lapho ama-spore eseqalile ukuhlakazeka. Lokhu kuhlukahluka kubonisa izigaba ezahlukene zomjikelezo wokuphila kwesikhunta ezenzeka ngesikhathi esisodwa ngaphakathi kwendlebe efanayo.
Ingemuva lifiphele kancane ngokujula okungajulile kwensimu, okubonisa amaqabunga ommbila aluhlaza kanye neziqu ezibonisa indawo enkulu yensimu yommbila. Lesi sizinda semvelo sinikeza ulwazi oluhambisana nesimo ngenkathi kuqinisekiswa ukuthi indlebe ethelelekile ihlala iyisihloko esicacile sesithombe. Ukukhanya kubonakala kungokwemvelo futhi kufana, cishe kuthathwe ngaphandle emini, okuvumela ukuthungwa kwezicubu zezitshalo kanye nezakhiwo zesikhunta ukuthi kubonakale kahle.
Imininingwane emihle efana nemicu yesilika enemicu, ukugoba okuncane kwamaqabunga e-husk, kanye nokubukeka okusanhlamvu kwezinhlamvu ezimnyama kunegalelo ekhwalithini yesayensi neyombhalo wesithombe. Isithombe siqokomisa ngempumelelo izinguquko ezinkulu zomzimba ezibangelwa ukutheleleka kwe-corn smut, okuguqula lokho okuvame ukuba yindlebe efanayo yommbila kube yiqoqo lezinhlobo ezivuvukele zesikhunta. Ngenxa yalokho, isithombe sisebenza njengesigcawu semvelo esikhangayo kanye nomfanekiso wemfundo wesifo sezitshalo esaziwayo esithinta izitshalo zommbila.
