El I-Populus tremuloides Sihlahla lesisemkhatsini lesinemacembe lamakhulu emndeni waSalicaceae.. Eyaziwa kakhulu ngegama le-aspen. Ingenye yezinhlobo ezisabalele kakhulu endaweni yaseNyakatho Melika. Yisitshalo esifushane lapho ezimweni ezifanelekile singafinyelela futhi seqe iminyaka engama-80. Sinezici ezinhle kakhulu amagxolo aso amhlophe amhlophe, amahlamvu awo amnyama aluhlaza okhangayo anyakazisa ngisho nangomoya omncane nombala wawo ophuzi wegolide.
Umsuka kanye neHabitat
Ludabuka ezindaweni ezinezintaba namakhaza eNyakatho Melika, kusukela e-Alaska ebandayo, kweqa iCanada nokuwela amabanga amakhulu ezintaba zase-United States yaseNyakatho Melika, kuze kufike ezintabeni zaseMexico. Kungabonakala ezindaweni eziphansi futhi ezinomswakama, kanye nasemahlathini aswakeme emazweni aphakeme futhi kuyisitshalo esine-dioecious, enezimbali zesilisa nezinsikazi ezivela ezindaweni ezihlukene ze-raceme inflorescences ezikhunjeni ezihlukene.
Izici zePopulus tremuloides
El I-Populus tremuloides isihlahla ukuthi ingadlula amamitha angama-25 ukuphakama. Inesiqu eside, esiyindilinga futhi esibushelelezi, esinokufuduka okuphansi, sinomqhele omfushane onokubukeka okuyindilinga. Amagxolo alo abushelelezi futhi amuncu, enethoni eluhlaza okotshani noma emhlophe lapho isencane, eba mnyama futhi ishaywe ngokuhamba kwesikhathi, ibhalwe imiphetho emide nengxenye yayo ephezulu isicabalele.
Ngokuphathelene namagatsha awo, lawa mancane, aluhlaza okomnyama noma ompunga, ayindilinga engxenyeni yesiphambano. Ama-lenticel amise okweqanda ayabonakala ebusweni bawo. Kepha amahlumela, ukuphela kungu-6 kuye ku-7 mm ubude, amaqabunga amakhulu namahlumela amancane amaqabunga. Ukubukeka kwawo kuyindilinga, lanceolate futhi kusondele egatsheni, kugobile kancane ekugcineni, kunesikali esinsundu esiphakathi kuka-6 no-7, esicishe sibe nenhlaka, ngaphandle kwephunga.
Amaqabunga awo a-ovate futhi amile okwezinso, enwetshiwe elinganiselwa kumasentimitha ayi-6 noma ngaphezulu, abukhali esicongweni saso nangesisekelo esiyindilinga, esinamazinyo, siluhlaza ngaphezulu phezulu futhi sibekeke kancane ngaphansi kwaso, imvamisa siyicwebezela. Izithelo ze-poplar zingamaphilisi amancane acwebezelayo, anezinhlamvu eziyishumi ngaphakathi. Lezi zinhlamvu zivuthwa phakathi kwamasonto amane kuya kwayisithupha emva kokuqhakaza. Ukuqoqwa kwembewu kuchichima njalo eminyakeni engu-4 kuya kwengu-6. Ukuhluma kwezinhlobo zalezi zinhlobo kuyinto engenhla futhi izimpande zayo ziyasakazeka, zinomsoco futhi kunzima ukuzilima.
Izifo nezinambuzane
Ubhabhulini Zijwayele izifo eziningi, kufaka phakathi amabala amaqabunga, ama-rusts, i-powdery isikhutha esesabekayo, kanye namankankane. Izitshalo ezigulayo njalo uhlushwa ukwehla kwamaqabunga ngaphambi kwesikhathi ngenxa yokungakhululeki. Ngokuqondene nezinambuzane, abagxeki abavame kakhulu bahlanganisa amacimbi, ama-borer, izintwala nezikali ezicasulayo. Izihlahla ezigcizelelwe kusuka ehlobo elithathe isikhathi eside zisengozini yezifo ezinjengokubuyela emuva kanye nezibi.
Ukutshala
Ukukhula okungcono, kufanele itshalwe enhlabathini ecebile, emanzi, egcwele, nenhlabathi ekhishwe kahle. Endle, ikhula ngezinhlobo ezahlukahlukene zenhlabathi, kusuka enhlabathini enamadwala phezulu ezintabeni kuya enhlabathini yobumba ezindaweni eziphansi. Isebenza kahle ezindaweni ezibandayo ezisenyakatho, kepha iyathinteka ekushiseni nasehlobo lomswakama. Akubekezeleli ukungcola okuningi emadolobheni.
Endaweni yabo yokuhlala ubonakala enza ama-ashera, lapho zonke iziqu eqenjini ziyizinhlobo zama-clones ezikhula zisuka ohlakeni olulodwa lwempande. Ngakho-ke, kungenzeka ukuthi amaqoqo amakhulu aqala esiqwini esisodwa. Njengoba kuyinhlobo yohlobo lwe-dioecious, iqembu ngalinye lazo lakhiwe ngama-clones wesilisa noma wonke ama-clones abesifazane.
El vusa ikhula ngokushesha kusuka ezimbewini zezimbewu nezimpande. Njengoba sekushiwo, ivumelana cishe nazo zonke izinhlobo zenhlabathi, kuze kufike ezingeni lokuthi ukhula oluzungeze isihlahla, esikhundleni sokulusithinta, lungakhulisa ukukhula kwalo ngendlela emangalisayo. Uma utshalwe eqenjini, iziqu ezindala nezonakalisiwe kufanele zisuswe ngezikhathi ezithile ukuze kuvele ukuvela kwamahlumela amasha.
