El populus tremuloides Ngumthi ophakathi ngokomyinge ophakathi osapho lakwaSalicaceae.. Ngokuqhelekileyo yaziwa ngegama le-aspen. Enye yezona ntlobo zixhaphake kakhulu kummandla waseMntla Melika. Sisityalo esihlala ixesha elifutshane esinokuthi kwiimeko ezifanelekileyo sifikelele kwaye sidlule kwiminyaka engama-80. Sinezimpawu ezibalaseleyo zamaxolo amahle amhlophe, amagqabi awo amnyama aluhlaza anomtsalane oshukuma nangomoya nje omncinane nombala wawo omthubi obugolide.
Imvelaphi kunye neHabitat
Inzalelwane yeentaba kunye neendawo ezibandayo zaseMntla Melika, ukuqala kwiAlaska ebandayo, ukuwela iCanada kunye nokuwela iindawo eziphambili zeentaba zaseMelika eMantla Melika, de kube kufikelela kwiintaba zaseMexico. Ingabonakala kwiindawo eziphantsi kwaye ezinomswakama, kunye nakumahlathi afumileyo akumhlaba ophakamileyo kwaye sisityalo esine-dioecious, eneentyatyambo ezingamadoda nezamabhinqa ezivela kwiindawo ezahlukeneyo ze-raceme inflorescence kwiindawo ezahlukeneyo.
Iimpawu zePopulus tremuloides
El populus tremuloides ngumthi ingadlula kwi-25 yeemitha ukuphakama. Inomboko omde, ojikelezayo nogudileyo, onokufuduswa okuphantsi, inesithsaba esifutshane esinenkangeleko erhangqiweyo. Ingxolo yayo igudile kwaye iyatyibilika, ngombala oluhlaza ocacileyo okanye omhlophe xa umncinci, othi ubemnyama kwaye utyhaleke njengoko ixesha lihamba, ibhalwe imiphetho edibeneyo nenxalenye yayo ethe tyaba.
Ngokunxulumene namasebe awo, ezi zincinci, ziluhlaza mnyama okanye ngwevu, isetyhula kwicandelo lokuwela. Iilensi ezimile okweqanda zibonakala kumphezulu wayo. Ke wona amahlumelo, I-terminal yi-6 ukuya kwi-7 mm ubude, amathupha amakhulu kunye namagqabi amancinci amancinci. Inkangeleko yayo iyafana, ine-lanceolate kwaye isondele kwisebe, egobile kancinci ekugqibeleni, inezikali eziphakathi kwe-6 kunye ne-7 ezimdaka ngombala, zinentlaka, zingenasongo.
Amagqabi ayo amile okweqanda kunye nezintso, ngolwandiso oluqikelelwayo lweesentimitha ezi-6 okanye nangaphezulu ubude, obukhali kwincopho yalo kunye nesiseko setyhula, esinamazinyo, esiluhlaza kumphezulu waso kunye nesiphatho esincinci ngaphantsi, esihlala sibengezela. Iziqhamo zepoplar zincinci, zinee-capsule ezinobumba, ezineembewu ezilishumi ukuya ngaphakathi. Ezi mbewu zivuthwa phakathi kweeveki ezi-4 ukuya kwezi-6 emva kokudubula. Ukuqokelelwa kwembewu kuninzi rhoqo kwiminyaka emi-4 ukuya kwemi-5. Ukuhluthwa kwezi ntlobo kuyinto engaphezulu kwaye iingcambu zayo ziyasasazeka, zinencasa kwaye kunzima kakhulu ukuzilima.
Izifo kunye nezitshabalalisi
Iipopu Banobungozi kwizifo ezininzi, kubandakanya amabala amagqabi, iirhasi, ukungunda okungumgubo kunye neenkonkxa. Izityalo ezigulayo rhoqo banengxaki yokuwa kwegqabi ngaphambi kwexesha ngenxa yokungonwabi. Ngokuphathelele izinambuzane, abagxeki abaqhelekileyo baquka imibungu, iibherer, ntwala nezikali ezicaphukisayo. Imithi egxininiswe kwihlobo ixesha elide ichaphazeleka ikakhulu kwizifo ezinje ngokubuya kunye neeborer.
Ukutyala
Ukukhula okungcono, kufuneka ityalwe kwindawo etyebileyo, efumileyo, egcwele ilanga, kunye nemihlaba efumileyo. Endle, ikhula kwiintlobo ezahlukeneyo zomhlaba, ukusuka kwimihlaba enamatye ephezulu ezintabeni ukuya kwimihlaba yodongwe kwiindawo ezisezantsi. Ikhula kakuhle kwimozulu ebandayo esemantla, kodwa ichaphazeleka bubushushu behlobo kunye nokufuma. Ayikunyamezeli ukungcoliswa kweedolophu.
Kwindawo yazo yokuhlala ubonwa esenza iiashera, apho zonke iziqu kwiqela zineentlobo zeeklone ezikhula kwinkqubo enye yengcambu. Yiyo loo nto izihloko ezinkulu zisenokuba zaqala kwisiqu esinye. Njengoko luhlobo lohlobo lwe-dioecious, iqela ngalinye lazo lenziwe ngamadoda okanye onke amabhinqa.
El Aspen ikhula ngokukhawuleza ukusuka kwimbewu nakwiingcambu. Njengoko sele kutshiwo, iyaqhelana nazo zonke iintlobo zomhlaba, kangangokuba ukhula olujikeleze umthi, endaweni yokuwuchaphazela, lunokwandisa ukukhula kwalo ngendlela emangalisayo. Ukuba zityalwe kwiqela, iziqu ezindala nezonakalisiweyo kufuneka zisuswe ngamaxesha athile ukulungiselela ukuvela kwamahlumelo amatsha.
