Eqoqweni elinothile lama-evergreen conifers wezingadi zethu ze-botanical, kusanda kuvela umhlali omusha. Ngokungafani namanye ama-conifers, umuthi omusha, njenge-larch, uphonsa izinaliti kanye namahlumela amancane ebusika. Manje, izihlahla ezithambile sezifinyelele, ngokwesibonelo, ukuphakama okungamamitha ayisikhombisa engadini ye-botanical yaseKiev University.
I-Metasequoia (Metasequoia). © Line1Umlando omubi wesihlahla. Ngo-1941, isazi sezitshalo saseChina, uSolwazi T. Kang, ehlola lezi zimila ezintabeni ezingenakufinyeleleka emngceleni wezifundazwe zaseHubei nezaseSichuan, wathola isihlahla esingamamitha angama-52 siphethe isiqu esakhiwe ngamagxolo abomvu nezinaliti eziluhlaza ezithambile. Lesi sihlahla asizange sifakwe kuhlu lwamazwe omhlaba, hhayi omunye wezazi zezitshalo owasikhulumayo.
Ngo-1946-1947, uhambo lwaluhlomele ukutadisha lokhu okutholwe, lokuqoqa imbewu yesitshalo esisha okokuqala. Ukuphuma kwethu kuthola ezinye zalezi zihlahla ezingaba ngu-1000, futhi sathola ukuthi lesi sitshalo esisha sisatshalaliswa endaweni engamakhilomitha skwele angama-750 kuphela, sikhula endaweni ephakeme ngamamitha ayi-650-1200 kunhlabathi enesihlabathi. Abantu bendawo bayibiza nge- "shui-sha", okusho ukuthi "i-spruce yamanzi." Umuthi ufana ne-sequoia enkulu, okwaxoxwa ngayo ngaphambili, futhi wabizwa nge-metasequoia.
Izinaliti Metasequoia. © Derek RamseyI-Metasequoia inentshisekelo kakhulu kososayensi emhlabeni wonke. Eminyakeni eminingana, kuye kwavela imisebenzi eminingi yesayensi kulesi sitshalo. Ukuseshwa kwenziwa kuyo yonke indawo, kepha akukho emgodini womhlaba lapho i-metasequoia ingatholakala ngaphansi kwezimo zemvelo.
Kodwa-ke, lapho umuzwa waziwa ama-paleobotanists, athi kade ayifunda le metasequoia evela emaphepheni ematsheni, ngo-peat strata nakwamanye ama-deposits futhi abheka njengesitshalo esivele safa.
IMetasequoia yayingesinye sezihlahla ezivame kakhulu emhlabeni wezitshalo ezilandelwayo. Amahlathi alo ahlanganisa izindawo ezinkulu ukusuka eKorea efudumele kuya e-Arctic enokhahlo. Kutholakale imishini yokudonsa umoya ngesikhathi kubembiwa eCalifornia, Greenland naseKazakhstan. Lesi sitshalo esisanda kutholwa sibuye sasebenza njengabathokozi be-paleobotanists (ngemuva kwakho konke, kuzodingeka balahle isitshalo esisodwa ku-akhawunti yabo), ngoba kwaqinisekisa ukunemba kwencazelo yabo yemvelo yezitshalo zasendulo.
Metasequoia glyptostroboid, noma Metasequoia glyptostroboid (Metasequoia glyptostroboides).
Ososayensi baseChina bathumela imbewu yesihlahla abayithola emazweni ahlukahlukene omhlaba. Izithombo zeMetasequoia zangena eLeningrad, ezindaweni ezishisayo, ogwini loLwandle iMedithera. Manje lesi sihlahla singatholakala eFrance, eFinland naseBrazil. Kwavela ukuthi iyamelana nesomiso, ibekezelela ama-degree angama-30 futhi iqhwa kakhulu. Manje ezinye izici zemvelo ze-metasequoia sezifundiwe. Isibonelo, isakazeka kalula ngokusika, ngokungajwayelekile kusenesikhathi ukuze izihlahla ziqale ukuthela izithelo. Njengoba isineminyaka engu-5 ubudala, futhi nangaphambilini, yakha izinhlamvu zokuqala, lapho amahlathi akhulisa ngempumelelo izizukulwane zayo ezintsha.
Ngakho-ke ukuzalwa kwesibili kwe-metasequoia kwenzeka.
