La I-Selaginella isitshalo esidabuka ehlane laseChihuahuan, okuyi yakhiwa cishe izinhlobo ezingama-700 ezihlonziwe, ezisatshalaliswa izifunda ezibanzi emhlabeni. Ikhonjwa ngamanye amagama afana nalawa: Siempreviva noma iDoradilla.
Izici ezijwayelekile
Ama-subspecies alesi sitshalo abonakala ngokuba luhlaza njalo. Ezinye zazo zivela emahlathini asezindaweni ezishisayo ezinomswakama, kanti ezinye ziye zajwayela izimo zezindawo ezomile kakhulu ezinezikhathi ezinde zesomiso, lapho zikwazi khona ukusinda ngenxa yokuthi amaqabunga azo amancane ane-cuticle ejiyile evikelayo, ehlangana ngalokho uhlangana njengebhola ngenkathi isomiso sisaqhubeka, nciphisa indawo yomjuluko futhi umelane nayo kuze kuphele isizini.
Njengoba zinamandla okubuyela esimweni sazo sokuqala lapho izimo zezulu zivuma, babizwa ngesitshalo sokuvuka. the i-selaginella Ihlukaniswa ngokugoba kwayo ngokwengxenye nangokumile ngokwengxenye lapho kuvela khona inani elikhulu lama-ramifications, ayinamafindo futhi ayinawo ama-internode, izimpande nazo ziningi futhi zinobuhle.
Amaqabunga amancane afakwe izikali nawo angabonakala esiqwini esisekelweni nje se-ligule, lapho isitshalo simunca khona amanzi abekwe emaqabungeni bese ewathumela ohlelweni lokujikeleza kwegazi. Intula izimbali, kepha kunalokho inama-sporophylls noma izitho umsebenzi wazo ukukhiqiza kabusha isitshalo, okufana nama-ferns.
Izinhlobo eziyinhloko ze i-selaginella
Lokho esizokhuluma ngakho ngezansi kusakazeke kakhulu ezifundeni ezahlukahlukene zomhlaba ngakho-ke kwaziwa kakhulu:
USelaginella Lepidophylla
Ejwayeleke kakhulu eMelika Ephakathi neseNingizimu, ama-rosettes amaqabunga aluhlaza avame ukuba bomvu uma esevuthiwe. Lezi zinhlanzana zizivikela ekomeni ngokuvala njengebhola futhi ibuyele esimeni sayo sokuqala lapho kubuya umswakama noma isimo sezulu esihle.
USelaginella Kraussiana
Lezi zinhlobo ezincane zivela eMpumalanga Afrika, ikhula ngokushesha okukhulu, inezimpande eziningi esiqwini futhi iyabaqombola.
I-Selaginella martensii
Enye yama-subspecies aziwa kakhulu avela eMexico. Iyehluka kunenye ngesiqu sayo esime siqonde nangaphandle, kanti amaqabunga aso makhulu futhi ayabukisa.
i-selaginella uncinata
Ungummeleli walolu hlobo lwezinhlobo ezinhle kakhulu futhi ezisetshenziselwa ukudala amatagi anotshani nokuwabeka kubhasikidi abamisiwe njengama-ferns.
USelaginella Helvetica
Kuyinto ejwayelekile ye-Alps futhi ihlukaniswa yimigqa emibili yamaqabunga amancane phezulu kanye nemigqa emibili yamaqabunga amakhulu kuya ezansi, wonke atholakala phezulu kwesiqu.
USelaginella Denticulata
I-subspecies ebucayi kakhulu enamagatsha amancane namaqabunga amancane aluhlaza aluhlaza afakwe emaphethelweni.
Ukunakekelwa kwezitshalo okujwayelekile
La i-selaginella Eqinisweni, ayidingi ukunakekelwa okuningi, noma kunjalo ikhetha izindawo ezinomthunzi noma ukuthi ilanga lifinyelela kulo ngokungaqondile. Ngakho-ke uma uzoyikhulisela ekhaya, thola indawo enhle nayo ekude nezinhlaka. Mayelana namazinga okushisa, ngokufanele, kufanele zibe ngaphezu kuka-16º noma u-18º.
Ngentwasahlobo - ehlobo lesi sitshalo sidinga ukuchelela njalo, ngakho-ke kufanele uqiniseke ukuthi i-substrate ihlale inomswakama kodwa ingagcwali. Ngokwengeziwe, ungayifafaza ngokuzungezile kanye ngosuku ukuze wakhe indawo enomswakama. Lesi sikhathi sonyaka sikulungele ukuhlinzeka umanyolo ku-substrate ngendlela elula kakhulu ngoba isitshalo asifuneki kakhulu kulokhu.
Yigcobe njalo emavikini ama-3 noma ama-4 uxuba umquba ophelele nekhwalithi namanzi okunisela, ngaphezu kwalokho wehlise kube ¼ umthamo onconyiwe kwiphakethe lomquba. Ukunisela ekwindla nasebusika kuncishisiwe, ngakho-ke izimo zomswakama endaweni ezungezile kufanele zigcinwe.
Izimbali nokuthena
Khumbula ukuthi lezi zitshalo zine-sporangia esikhundleni sezimbali, ezibhekene nokuzala. Lokhu kufanele kwenziwe kanye ngonyaka, lapho ukufakelwa kabusha kwenziwa entwasahlobo kusukela isitshalo sikhula ngokushesha okukhulu futhi ngendlela engahlelekile. I- ukuthena kwenziwa ngokusika amagatsha abe uhhafu wosayizi wawo.
