Kungamangalisa ukubona umthi onamagqabi abomvu, kuba ubuhlaza bawo bendalo buqhelekile, kodwa lo mbala wexesha lonyaka ungqinelwa lixabiso eliphantsi lokukhanya kwelanga ekwindla elichaphazela ukuveliswa kweklorofili kwaye lenze enye imbala ikhanye. ifihliwe. Kweli nqaku, sinikezela kuwe Yintoni uMthi oBomvu weLeaf kwaye siyakumema ukuba uqhubeke ufunda, ukuze ufunde kabanzi malunga nalo.
Umthi wamagqabi aBomvu
Ekwindla, xa umthi uqalisa ukulala, ukunikezelwa kweklorofili edlula emthini namagqabi awo aqalisa ukuvala. Ukungabikho kweklorofili kubangela ukulahleka kombala wamagqabi. Le khompawundi yodlula eminye imibala yale ndawo yesityalo kwaye idla ngokuba ngowona mbala ubalaseleyo obonwayo. Xa uhlaza lungekho, ezinye ii-shades zivela. Amagqabi asekwindla abomvu abangelwa yi-pigment ebizwa ngokuba yi-anthocyanin, eveliswa yiswekile evaleleke emagqabini ngeli xesha lonyaka. Nangona kunjalo, kukho ezinye izityalo ezifana neemephu ezibomvu ezinee-anthocyanins zendalo kunye namagqabi abomvu nangaliphi na ixesha lonyaka.
Okuninzi
Kukho iindawo ezininzi ezinomhlaba onzima kakhulu kunye ne-nitrogen encinci, apho imithi ithande ukuba neethoni ezibomvu ngaphezu kwesiqhelo, ngoko omnye wemisebenzi ye-Anthocyanin kukukhusela izityalo ekukhanyeni kwe-ultraviolet, ukuphepha ukuveliswa kweeradicals zamahhala. . Emva koko, sinikezela uluhlu lwemithi ebonisa le meko kunye namahlamvu abo abomvu abangela umphumo omangalisayo, ngenxa yokulungelelaniswa kwabo.
Iimaphu
Iimaphu lusapho olukhulu lwemithi, kuquka amalungu azo zonke iimilo kunye nobukhulu ukusuka kuluhlu olubanzi ngokulinganayo lwemozulu. Olunye uhlobo olunamagqabi abomvu yimaple ebomvu yenyoka (Acer capillipes), eyinzalelwane yase Japan, njenge maple amaninzi abomvu. Amagqabi awo abomvu xa eqala ukuvela entwasahlobo, aze ajike abe luhlaza ehlotyeni aze ajike abebomvu kwakhona ngaphambi kokuwa.
Ezinye iimaphu ezibomvu ezinamagqabi abomvu ziquka i-paperbark maple (Acer griseum), umthi onqabileyo okhulayo kunye nephepha elikhangayo, i-chestnut-brown bark, amagqabi anamaphecana ama-3, agudileyo kwaye amhlophe ngezantsi, Ajika abomvu obomvu ekwindla. Ngokwenxalenye yayo, i-maple yaseJapan «i-Burgundy Lace» (i-Acer palmatum), iqala ukuphulukana namagqabi ayo ebusika kwaye emva koko ivelise amagqabi awomeleleyo amfusa-bomvu entwasahlobo nasehlotyeni, ngelixa ekwindla ifumana umbala obomvu.
oki obomvu
Umthi okhulayo phantse nayiphi na indawo, le klasi yaseMelika inika umbala omkhulu wehlobo kunye nombala obomvu wokuwa. Ikhula ngokukhawuleza ngokukhawuleza kwaye ifikelela kwiindawo eziphakamileyo ze-18,5 ukuya kwi-23 yeemitha, kunye nokusabalalisa kwe-13,5 ukuya kwi-15 yeemitha. Lo mthi uxatyiswa ngenxa yeengcambu zawo ezinzulu, nto leyo eyenza ukuba ube luncedo ukutyalwa kufutshane nezitrato zasezidolophini nakwiindlela ezihamba ngeenyawo, uzalise ezi ndawo ngombala omhle xa kufika ikwindla yaye amagqabi awo ajike abebomvu nto leyo ethandwa ngabaninzi.
UFagus Sylvatica
Ngaphakathi kolu didi kukho i-Tricolor Beech, ebonakala ngokuba namagqabi amfusa entwasahlobo nasehlotyeni, igqabi ngalinye linamacangca apinki kwaye ngexesha lokuwa la magqabi ajika abebomvu. Ngexesha lokuvuthwa kwayo ingaba yi-3 ukuya kwi-6 yeemitha ukuphakama, ngelixa ububanzi besithsaba sayo bumalunga neemitha ezi-3 kunye nobuninzi beemitha ezi-7. Kwakhona, kukho uhlobo lwesityalo esibizwa ngokuba yi-purpurea (Beech), esinesithsaba esingqukuva kunye namagqabi amakhulu ombhoxo, anemiphetho yamaza ebonisa umbala obomvu oqaqambileyo ngexesha lekwindla.
intyatyambo dogwood
Olu luhlaza olunamagqabi aphuma kuMntla Melika, olunokongeza ubuhle kulo lonke ilizwe unyaka wonke kwaye ngakumbi ekwindla kuba iintyatyambo zalo zishiyana ngombala ukusuka komhlophe ukuya kobomvu kwaye namagqabi awo afumana umbala obomvu, ngoko ke agqame ukuba umthi obonakala kakhulu wexesha lonyaka. Ezi zityalo zinokukhula kwiimeko zemozulu ezahlukeneyo kunye neemeko zomhlaba, zikhula ngcono xa zityalwe kumthunzi ongaphelelanga kumhlaba ongenamanzi, otyebileyo we-humus oneasidi kancinane.
Ezinye iintlobo zeMithi ebomvu yeLeaf
Kweli candelo sikhankanya ezinye iintlobo zemithi enamagqabi abomvu, ngolwazi lobuninzi obukhoyo. Omnye wabo ngumthi omuncu: igama libizwa ngokuba yincasa ekrakra yamagqabi, aneencam ezincinci kunye ezikhazimlayo. Banokukhula ukuya kutsho kwiisentimitha ezingama-20 ubude kwaye bajonge ngandlel’ ithile njengamagqabi epesika, umtsalane wabo ophambili ngumbala obomvu wamagqabi awo ekwindla. Ukukhula kwayo ngokubanzi kwesi sityalo kukhawuleza, kufikelela kubude be-7,6 yeemitha.
Ukongezelela, kuyafaneleka ukuba uqaphele umthi we-apula obomvu obomvu, ongomnye weentlobo ezimbalwa ze-crabapple ezibonisa amahlamvu abomvu-mfusa. Iwashiya amagqabi ayo ekwindla kwaye ivelise iziqhamo ezincinci, ezikrakra kancinci. Le mithi ikhula ibe malunga neemitha ezi-6 ubude. Kukwaqukwe neentlobo ngeentlobo zeplam enamagqabi atsolo embhoxo anemibala eqala kobomvu kunye nemfusa ukuya koluhlaza kunye neeflekhi ezibomvu okanye ubhedu.
Ukongeza, kukho iintlobo ngeentlobo zemithi yomsi enikezela ngamahlamvu abomvu, anje ngokubizwa ngokuba yiFlame, Purpureous kunye neRoyal Purple. Enye yeempawu zabo kukuba anamagqabi amakhulu, amile okwe-oval kwaye avuthuluka, oko kuthetha ukuba amaqabunga awo awela ekwindla. Uninzi lubonisa ubude obujikeleze i-7,6 yeemitha. Olunye udidi lokugqamisa yiCercis canadensis Forest Pansy, edla ngokuba ne-branched trunk ukusuka kwisiseko kunye nesithsaba esibanzi, esijikelezileyo, ngelixa amagqabi ayo amakhulu anjengentliziyo agcina umbala obomvu obomvu omfusa.
Imithi yeSweetgum ikhangeleka iqaqambe kakhulu ekwindla xa amagqabi ayo ejika abe nemibala eqaqambileyo ebomvu. Bafuna indawo elangeni elipheleleyo okanye emthunzini. Zikhula phantse kuwo nawuphi na umhlaba, ukusuka kwisanti ukuya kudongwe kunye neasidi ukuya kwialkaline kancinane. Amagqabi omthi wentlaka eswiti aneentsimbi ezintlanu ukuya kwezisixhenxe ezitsolo, kwaye ukumila kwazo kufana nenkwenkwezi. Amagqabi aqolileyo ayi-10 ukuya kwi-18 cm ububanzi. Umbala wayo wokuwa uhlala ixesha elide kunolo lwemithi emininzi.
Olunye uhlobo lwenziwe ngumthi weMalus Lizeth, ofaneleke kakhulu kwiindawo ezincinci zegadi, kuba amahlamvu awo ajika abebomvu ngexesha lokwindla njengoko ekhula. Ngaphandle kwamahlamvu athandekayo, ineentyatyambo eziqala ngokubomvu kwaye zivuleleke ukubonisa amagqabi abomvu, nto leyo eyenza ibe ngumthi omangalisayo. Ekugqibeleni, kukho iimpondo, eziyimithi emincinane ethi, emthunzini weminye imithi, ivuleke yaye ibukeke imile kakuhle, kodwa ekukhanyeni kwelanga, iba nohlobo oluxineneyo noluqinayo lokukhula, xa kufika ukwindla, umthi uyaphila. enamagqabi amibalabala kwimithunzi ebomvu, e-orenji kunye netyheli.
Ukuba uthanda eli nqaku malunga nokuba yintoni na uMthi oBomvu, siyakumema ukuba ufunde amanye amanqaku aqulethe izihloko ezinomdla kwezi zikhonkco zilandelayo:
