El I-Taxus brevifolia iyisihlahla se-coniferous shrub somndeni I-Taxaceae, owaziwa ngegama likaTejo del Pacífico. Yisitshalo esiphakathi nendawo esingadlula amamitha angama-20 ukuphakama.; ibuye iphile isikhathi eside impela. Yiyo kuphela yew ebaluleke kakhulu kwezentengiso eNyakatho Melika, ngenxa yokuthi ikhompiyutha esetshenziswe kwezinye izinhlobo zomdlavuza ikhishwa emagxolweni awo.
Umsuka nendawo yokuhlala
IPacific yew iyinhlobo edabuka eNyakatho Melika, ingabonakala endle ezifundeni ezifana nogu lwePacific lwaseningizimu-mpumalanga ye-Alaska, eningizimu ye-United States yaseNyakatho Melika ohlangothini olusentshonalanga yeBritish Columbia esifundazweni saseCalifornia ikhona nasezifundazweni zaseMontana, Idaho nase-Oregon. Ikhula ezindaweni eziphakeme ezisukela kumamitha angama-0 kuye kwangama-2200 ngaphezu kogu lolwandleKuwo womabili amahlathi avulekile futhi aminyene, isakazeka emifudlaneni, emathafeni anamanzi nasemithambekeni.
Izici ze-Taxus brevifolia
Sihlahla esihlala siluhlaza esikhula ngokulingene esiphakathi kwamamitha ayi-5 kuya kwayi-15 ukuphakama, noma kunjalo izibonelo ezedlula amamitha angama-20 ziyaziwa. Umboko umile kancane usontekile, amagxolo alo anezikali anezikali ezibomvu eziphenduke zaba nsomi, amagatsha awo asuka ekukhuphukeni aye ekuweni. Amahlumela awo aluhlaza okotshani futhi azungezwe ngokuphelele izisekelo eziphansi zamaqabunga.
Inamaqabunga aluhlaza, aqondile, acashile, aguquguqukayo, imvamisa ayanyinyitheka, anesisindo esiphakathi nendawo esincanyana ngaphezulu kanye ne-stomata ngamabhande amabili aluhlaza okwesibhakabhaka anemigqa emi-5 kuye kwayi-8 ngaphansi kwayo, ehlanganiswe nepetiole emfushane nesisekelo seqabunga okungaphakathi. It has izigaxa impova kokubili wedwa futhi ngamaqembu. Imbewu yayo ivundile futhi ivuthwe ngasekupheleni kwehlobo. Izinkuni zalolu hlobo zinamandla futhi zinzima.
Idatha ebalulekile
Kuyinhlobo yokukhula okuhamba kancane ngokweqile, okuyi ikhula ngesilinganiso samasentimitha angama-20 ngonyaka, ngakho-ke ivame ukubola kusuka ngaphakathi, kwakheke izikhala eziyize ngaphakathi. Lokhu kwenza kube nzima ukubala izindandatho zabo, ngakho-ke iminyaka yobudala bezinhlobo azikwazi ukunqunywa. Ukukhula kwayo kancane kubanga ukuthi ikoloni leTaxus nalo lihamba kancane, ngisho nakulezo zindawo ezinezimo ezifanele.
Izifundo ezihlobene nokululama kwazo ngemuva kokugawulwa kanye nemininingwane eqoqwe ezihlahleni ezimakwe ezimaweni, iqinisekisa umbono wokuthi yize luhlobo olwandisiwe, luphumelela kakhulu ngokulandelana sekwedlule isikhathi. Iyazwela kakhulu emlilweni futhi ukutakula kwayo kuhamba kancane. Lesi sitshalo sithola indawo esezingeni eliphakeme kakhulu kanye nobuningi beziqu zabantu abadala emahlathini okuthiwa amadala.
Sebenzisa
Abantu bomdabu basogwini olusePacific eNyakatho Melika banikeza ukubaluleka okukhulu kwezinkuni zeTaxus zokumelana nayo, ababeyisebenzisa ukwenza izikhali nezinye izinto zokusebenza. Njengamanje iyasetshenziswa ekwandisweni kwezinsimbi zomculo ezinjengezintambo zomculo ezinezintambo nezinye.. Kukhona labo abasathanda izinkuni zalo ukwenza iminsalo, eJapan kusetshenziselwa ukwenza izigxobo ze-toko zomkhosi.
Ngasekuqaleni kweminyaka yama-XNUMX, abacwaningi bakwazi ukukhomba inhlanganisela yamakhemikhali eTaxus brevifolia ebizwa nge-paclitaxel. Kamuva okufanayo savunywa ukwelapha umdlavuza we-ovari kanye nama-carcinomas athile ezilwaneni, namuhla ithengiswa ngaphansi kwegama lokuhweba iTaxol. Ukusetshenziswa kwayo kwamukelwe nasekwelapheni umdlavuza ohlobene nengculazi.
Izifo nezinambuzane
Ngokuvamile izinhlobo zomndeni I-TaxaceaeZiyakwazi ukumelana kakhulu futhi azijwayele izifo eziningi nezinambuzane. Kodwa-ke, ukuba khona kwezingcindezi ezahlukahlukene kungadala ukuthi bashintshe babe nsundu.
Isikhunta esikhona eTaxus siyivikela ezifweni nasezilwaneni ezidla ezinye, kepha uma indawo yoma kakhulu khona-ke lelo fungus elifanayo lingaba yisifo sesitshalo. Esinye isici esivame ukuthinta lezi zinhlobo ukugawulwa kwemithi ngokungakhethi, elenza inhlabathi ivezwe kakhulu yilanga nomoya, okwenza inhlabathi yome.
