El ITaxus brevifolia sisihlahla esiyi-coniferous shrub esivela kusapho Iirhafu, okwaziwa ngegama likaTejo del Pacífico. Sisityalo esinobukhulu obuphakathi nesinokudlula ngaphezulu kweemitha ezingama-20 ukuphakama.; ikwaphila ixesha elide. Yiyo kuphela yew ebalulekileyo kwezorhwebo eMntla Melika, enkosi kwinto yokuba ikhompawundi esetyenziswe kwezinye iintlobo zomhlaza ikhutshwe kwi-bark yayo.
Imvelaphi kunye nendawo yokuhlala
IPacific yew luhlobo lwendalo eMntla Melika, inokubonwa endle kwimimandla enje ngePacific yonxweme kumazantsi mpuma eAlaska, emazantsi eMelika eMntla Melika kwicala lasentshona leBritish Columbia kwilizwe laseCalifornia. ikwakhona eMontana, Idaho nase-Oregon. Ikhula kwiindawo eziphakamileyo ukusuka kwi-0 ukuya kwi-2200 yeemitha ngaphezulu komphakamo wolwandleKuwo omabini amahlathi avulekileyo nalawo ashinyeneyo, isasazeka ecaleni kwemilambo, amathafa amanzi, kunye namathambeka.
Iimpawu zetaxus brevifolia
Ngumthi ohlala uluhlaza okhula ngokomndilili ophakathi kwe-5 kunye ne-15 yeemitha ukuphakama, nangona kunjalo iisampulu ezingaphezu kwe-20 yeemitha ziyaziwa. Umboko umi ujijekile kancinci, Ixolo laso elinemibala linezikali ezibomvu ezijika zibe mfusa, amasebe alo anyuka aye ekuweni. Amahlumela awo aluhlaza kwaye ajikelezwe ngokupheleleyo ngamagqabi aphantsi.
Inamagqabi aluhlaza, amdaka ngokufihlakeleyo, amagqabi agobekayo, ahlala eqhekeza, enendawo encinci emxinwa kumphezulu wayo kunye ne-stomata kumabhanti amabini aluhlaza-luhlaza anemigca emi-5 ukuya kweli-8 kwicala layo elingaphantsi, elijikelezwe ngepetiole emfutshane kunye nesiseko segqabi. engenayo. Inama-pollen cones iyodwa kwaye ingamaqela. Imbewu yayo ivuthiwe kwaye ivuthwe ngasekupheleni kwehlobo. Umthi wale ntlobo womelele kwaye unzima.
Idatha ebalulekileyo
Luhlobo lokukhula kancinci kancinci, okuthi ikhula ngezinga leesentimitha ezingama-20 ngonyaka, ke ihlala ibolela ngaphakathi, isenza izithuba ngaphakathi. Oku kwenza ukuba kube nzima ukubala amakhonkco abo, ke iminyaka yobudala beesampulu ayinakumiselwa. Ukukhula kwayo kancinci kubangela ukuba ikolonisation yeTaxus icothe, nkqu nezo ndawo zinemeko efanelekileyo.
Izifundo ezinxulumene nokubuyiselwa kwabo emva kokuwa kunye nedatha eqokelelwe kwimithi ephawulwe kwizitendi, iqinisekisa ubungqina bokuba nangona luhlobo olwandisiweyo, lubonakala ngokulandelelana kade. Inovakalelo kakhulu emlilweni kwaye ukubuyiswa kwayo kuhamba kancinci. Esi sityalo sifezekisa eyona ndawo iphantsi kakhulu kunye nokuxinana kweziqu zabantu abadala kula mahlathi kuthiwa mandala.
Sebenzisa
Abantu bomthonyama kunxweme lwePasifiki kuMntla Melika banike ukubaluleka kweenkuni zeTaxus ngokuchasene nayo, ababezisebenzisa ukwenza izixhobo kunye nezinye izixhobo. Okwangoku iyasetyenziswa ekwandisweni kwezixhobo zomculo ezinje nge lute kunye nezinye izixhobo zomtya.. Kukho abo basakhetha iinkuni zayo ukwenza izaphetha, eJapan isetyenziselwa ukwenza iipali ze-toko.
Ekuqaleni kwee-XNUMX, abaphandi babenakho ukufumanisa imichiza e-Taxus brevifolia ebizwa ngokuba yi-paclitaxel. Kamva ngokufanayo savunywa ukunyanga umhlaza we-ovari kunye ne-carcinomas ethile kwizilwanyana, namhlanje ithengiswa phantsi kwegama lorhwebo iTaxol. Ukusetyenziswa kwayo kwamkelwe kunyango lomhlaza onxulumene noGawulayo.
Izifo kunye nezitshabalalisi
Ngokubanzi iintlobo zezosapho IirhafuZixhathisa kakhulu kwaye azihambelani nezifo ezininzi kunye nezitshabalalisi. Nangona kunjalo, ubukho boxinzelelo olwahlukeneyo kunokubangela ukuba bajike babe mdaka.
Ifungus ekhoyo kwiTaxus iyayikhusela kwizifo nakwizilwanyana ezihlasela irhamncwa, kodwa ukuba indawo iyoma kakhulu loo fungi inokuba sisifo kwisityalo. Enye into edla ngokuchaphazela iintlobo zezilwanyana kukungena kwemithi ngokungakhethiyo, owenza umhlaba ubhenceke elangeni nasemoyeni, obangela ukuba umhlaba ubune.
