Ukuhlola Umhlaba Wezitshalo Ze-Tissue Culture Philodendron: Uhlolojikelele Oluphelele

Amahlamvu aluhlaza futhi aqhakazile ezitshalo ze-Philodendron azenze zaba ukukhetha okudumile phakathi kwabathandi bezitshalo nabahlobisi bangaphakathi ngokufanayo. Ngekhono lazo lokuchuma kokubili ngaphakathi nangaphandle, lezi zitshalo ziletha ukuphila nobuhle kunoma iyiphi indawo ezihlala kuyo. Kodwa-ke, ukukhulisa izitshalo ze-Philodendron ngezindlela zendabuko ezifana nembewu noma ukusikwa kungaba umsebenzi onzima. Yilapho isiko lezicubu lingena khona njengendlela yokuguqula evumela ukukhiqizwa ngobuningi bezitshalo ze-Philodendron ngenkathi kugcinwa izici zazo eziyingqayizivele. Kulo mbono obanzi, sizongena ezweni elithakazelisayo lezitshalo ze-tissue Philodendron futhi sihlole izinzuzo eziningi nokucatshangelwa okuhlotshaniswa nale ndlela entsha yokusabalalisa.

Izisekelo ZeSiko Lwezicubu

I-tissue culture, noma i-micropropagation, iyindlela esekwe elabhorethri esetshenziselwa ukuphindaphinda ngokushesha izitshalo ngaphansi kwezimo eziyinyumba. Kuhilela ukuthatha izingcezu ezincane zezicubu zezitshalo, ezibizwa ngokuthi ama-explants, futhi uzibeke endaweni yesiko elicebile izakhi ezikhuthaza ukukhula nokuthuthuka kwazo. Lezi zitshalo zikhethwa ngokucophelela esitshalweni somnikeli, kuqinisekiswe ukuthi zinezici nezimfanelo ezifiselekayo. Ngochungechunge lwezinyathelo zokucophelela, njengokuvala inzalo, ukuphindaphinda, kanye nokujwayela, isiko lezicubu livumela ukukhiqizwa kwezitshalo eziningi ezifana nokwenziwa kofuzo esikhathini esifushane uma kuqhathaniswa.

Enye inzuzo eyinhloko yesiko lezicubu yikhono layo lokudlula inqubo ende nengaqinisekile yezindlela zokusabalalisa zendabuko. Ngosiko lwezicubu, abalimi bangafinyelela ukufana ngobukhulu besitshalo, ukuma, namandla. Lokhu kuvumelana kubaluleke kakhulu lapho kukhiqizwa izitshalo ze-Philodendron ngezinjongo zokuthengisa noma amaphrojekthi amakhulu wokulungisa umhlaba. Ukwengeza, isiko lezicubu liqeda ingozi yokudlulisa amagciwane noma izifo ezingase zibe khona embewu noma ukusikwa, okuholela ezitshalweni ezinempilo ezinethuba elikhulayo lokusinda.

Ukulungiswa kwe-Substrate kanye Nenzalo

Ngaphambi kokuqala inqubo yesiko lezicubu, ukulungiswa okufanele kwe-substrate kubalulekile. I-substrate, eyaziwa nangokuthi i-culture medium, inikeza imisoco edingekayo ukuze izitsha zikhule futhi zithuthuke. Imvamisa, okuphakathi kuqukethe inhlanganisela yamahomoni ezitshalo, ama-macronutrients, ama-micronutrients, amavithamini nama-carbohydrate. Kubalulekile ukukhetha i-substrate eqondene ngqo nezidingo zezitshalo ze-Philodendron ukuqinisekisa ukukhula okuhle.

Ukufakwa inzalo kwe-substrate namathuluzi asetshenziswa ngesikhathi senqubo yesiko lezicubu kubaluleke kakhulu. Ukungcoliswa okuvela kubhaktheriya, isikhunta, noma amanye ama-microorganisms kungavimbela ukukhula kwe-explants futhi kuholele ekuhlulekeni kwesiko lonke. Ukuze uvimbele ukungcola, i-substrate ngokuvamile i-autoclaved ukuze ibulale noma yimaphi ama-microorganisms akhona. Ukwengeza, zonke izinto ezisetshenziswayo, ezinjengama-scapel, ama-forcep, imikhumbi ye-culture, nezindawo zokudlulisa, kumele zibulawe amagciwane kusetshenziswa into ebulala amagciwane noma ngokuchayeka emazingeni okushisa aphezulu.

Ukuqaliswa Nokuphindaphindwa Kwezichazi

Lapho i-substrate namathuluzi eselungisiwe, inqubo yesiko lezicubu ingaqala. Isinyathelo sokuqala sihilela ukuqaliswa kokukhipha, lapho izingcezu ezincane zezicubu zethulwa endaweni yesiko. Lesi sikhungo sihlinzeka ngemisoco namahomoni adingekayo ukuze izithombo zikhule zibe amahlumela noma izimpande ezintsha. Kubalulekile ukugcina izimo ze-aseptic eziqinile phakathi nalesi sigaba ukugwema noma yikuphi ukungcola okungaba khona.

Njengoba lezi zitshalo zikhula futhi zanda, zakha amaqabunga amancane noma izicubu ze-callus. Kulesi sigaba, inqubo yokuphindaphinda iqala, lapho izitshalo zezitshalo zihlukaniswa noma ziguqulelwe emithonjeni yamasiko amasha ukuze kuthuthukiswe ukukhula okuqhubekayo. Le nqubo ingaphindaphindwa izikhathi eziningi ukuze kuzuzwe ukuphindaphindeka okucacile kwezitsha, okuholela enanini elikhulu lezitshalo.

I-Rooting kanye ne-Acclimatization

Uma sekukhiqizwe inani elanele lezitshalo, isinyathelo esilandelayo ukufaka izimpande. Lokhu kufezwa ngokushintsha ukwakheka kwendlela yamasiko ukuze kuthuthukiswe izimpande. Amahomoni ahlukahlukene, njengama-auxins, ayengezwa ukuze aqalise ukukhula kwezimpande. Ama-plantlets abe esedluliselwa endaweni yokufaka izimpande lapho avunyelwa khona ukuthuthukisa uhlelo lwezimpande oluqinile futhi olunempilo.

Ngemuva kokukhula kwezimpande, ama-plantlets athola isikhathi sokujwayela ukuze avumelane nezimo ezingezona inyumba. Avezwa kancane kancane endaweni engaphandle, enomswakama kanye nezinga lokushisa okulawulwa ngokucophelela ukuze kuncishiswe ukushaqeka nokucindezeleka. Ngokuhamba kwesikhathi, njengoba ama-plantlets akhula aqinile iziqu namaqabunga, ayakwazi ukuqina futhi alungele ukukhula ezimweni ezihlosiwe zokukhula.

Izinselelo Nokucatshangelwa

Nakuba isiko lezicubu liye lashintsha ukusakazwa kwezitshalo ze-Philodendron, akunazo izinselele nokucatshangelwa kwazo. Okunye okukhathazayo okuyinhloko yizindleko nobunkimbinkimbi obuhambisana nokusungula ilabhorethri yesiko lezicubu. Izinto ezisetshenziswayo nezinto ezidingekayo, njengamagumbi okukhula, ama-laminar flow hoods, kanye nemidiya yezamasiko, kungabiza futhi kudinga ulwazi olukhethekile ukuze kusebenze ngempumelelo.

Ukugcina izimo ze-aseptic kuyo yonke inqubo yesiko lezicubu kungesinye isici esibalulekile esidinga ukunakwa okucophelela. Noma yikuphi ukungcoliswa kungaholela ekutheni isiko lonke libe sengozini futhi kuholele emizamweni ehlulekile yokusakaza. Ukuqapha okuvamile kanye nokuqaliswa kwezimiso eziqinile kuyadingeka ukuze kuqinisekiswe indawo eyinyumba.

Okunye okucatshangelwayo ukuzinza kwezakhi zofuzo zezitshalo ze-Philodendron ezikhuliswe ngezicubu. Nakuba isiko lezicubu lihlose ukukhiqiza izitshalo ezifana nezakhi zofuzo, kunethuba lokuhlukahluka kwe-somaclonal. Ukuhlukahluka kwe-somaclonal kubhekisela ekushintsheni kofuzo okungenzeka ngesikhathi sesiko lezicubu, okuholela ezitshalweni ezinezici noma izici ezihluke kancane. Ukunciphisa le ngozi, ukuhlolwa okuvamile nokukhethwa kwezitshalo ezifana nezici ezifiselekayo kubalulekile.

Isiphetho

I-tissue culture ngokungangabazeki iguqule umhlaba we-Philodendron plant propagation, ihlinzeka ngendlela ephumelelayo nethembekile yokukhiqiza ngobuningi. Ngokukhetha ngokucophelela izimila kanye nokusetshenziswa kwezimo eziyinyumba, abalimi bangakwazi ukuzuza ukunikezwa okungaguquki kwezitshalo ezinempilo kanye nezakhi zofuzo ezifanayo. Nakuba ukusungulwa kwelabhorethri yesiko lezicubu kungase kube inselele, izinzuzo zokukhiqiza izitshalo eziphezulu ze-Philodendron zikwenza kube ukutshalwa kwezimali okuzuzisayo kubalimi bezentengiselwano kanye nabathandi bezitshalo abashisekayo ngokufanayo. Ngakho-ke, kungakhathaliseki ukuthi ufuna ukulungisa ihlathi elimangalisayo lasendlini noma ukudala indawo enhle, izitshalo ze-tissue ze-Philodendron zinikeza isango lokuhlola ubuhle nokuhlukahluka kwalezi zitshalo ezikhangayo.
