Izityalo zinokuhlelwa ngeendlela ezahlukeneyo: ngohlobo lwentyatyambo, ngokobukhulu ezifikelela kubo xa sele zindala, ngokumila kwamagqabi azo ... Kodwa, kwizityalo, kukho udidi olusetyenziswa kakhulu kwaye ukwahlula izityalo Ngena monocot kunye dicots.
Athetha ntoni la magama mabini? Bahluke njani omnye komnye?
Izityalo ezizimeleyo
Iimonocots zizityalo ezidubula iintyatyambo (ii-angiosperms) ezibonakaliswa ngokuba necotyledon enye, okt kuphela kwegqabi elinye lakudala elivelayo xa lihluma endaweni yezimbini. Kodwa into enomdla ayipheleli apha, kodwa lo mahluko udlula ukuba mangaphi amagqabi ahluma xa imbewu ihluma. Ngapha koko, ukukhula kwabo kwahluke kakhulu kuleyo yamachaphaza. Ndicacisa ukuba kutheni:
Ezi ntlobo zezityalo azinakho ukukhula okwesibini okwenyani, oko kukuthi, azinaso isiqu sokwenene, kwaye ukuba usikekile, awuziboni izangqa zonyaka ozibonayo emithini okanye ematyholweni. Ngoba? Kungenxa yokuba abanayo i-cambium, esisicubu sesityalo esimnandi esiphakathi kwexolo kunye nelog, eyenziwe ngolwahlulo lweeseli zombungu. Ngaphandle kwayo, ii-monocot azinako ukuvelisa iinkuni, ke ukwanda kokuphakama kwenzeka ngendlela eyahlukileyo: ngokwandisa ii-internode njengoko zikhula.
Enye into enomdla kuyo Ilifa, ezinomdla, oko kukuthi, zonke ziphuma kwisiseko esinye. Ke, ingcambu yayo imfutshane, ayingeni nzulu kune-5-60cm kuxhomekeke kwisityalo. Njengomphumo wako konke oku, abanakuba namasebe amaninzi nokuba, umzekelo, imithi enamachaphaza amabi enza njalo. Yintoni egqithisile, amagqabi anemithambo ebonakalayo, efanayo, njengalezo zengca ezenza ingca.
Zeziphi iintlobo zezityalo ezizodwa? Kukholelwa ukuba kukho malunga namawaka angama-50 eentlobo, kubandakanya nengca, iintende, iibhalbous, okanye iiorchid. Makhe sibone eminye imizekelo:
IPhoenix canariensis (iCanary Island Palm)
Yiyo isundu ezixhaphakileyo kwiiCanary Islands (Spain). Ifikelela kubude obufikelela kwiimitha ezili-13, Isithsaba esenziwe ngepinate kunye namagqabi amade ukuya kuthi ga kwi-7 yeemitha. Umboko wayo ungqindilili, ukwazi ukulinganisa i-1m ubukhulu kwisiseko sayo.
Sisityalo esimnandi kakhulu, ukusukela oko umelana nobushushu kunye neqabaka ukuya -7ºC.
I-Tulipa sp (iTulips)
Zizityalo ezinobumba obuqhelekileyo eMiddle East. Kuqikelelwa ukuba Kukho malunga ne-150 yeentlobo kunye nenani elingenakubalwa lomxube. Uninzi lwazo luyathengiswa njengeentyatyambo zokuhombisa, njengoko imibala yazo imangalisa ngokwenyani.
Ukuze sikwazi ukuzonwabisa ngokuzeleyo, zityalwa ekwindla. Ke, entwasahlobo siza kuba negadi okanye ipatio ehonjiswe ngezi ntyatyambo ezintle.
Musa paradisiaca (ibhanana)
Sisityalo semifuno esityala imifuno kummandla wase-Indomalaya. Ifikelela kubude obuziimitha ezi-4, inamagqabi amade ukuya kuthi ga kwi-2m. Ivelisa iziqhamo ezaziwa ngabantu bonke: ibhanana, enokulinganisa ukusuka kwi-7 ukuya kwi-30cm ubude ukuya kuthi ga kwi-5 ububanzi.
Inokubakho emhlabeni kunye nasembizeni, kodwa kucetyiswa ngakumbi ukuba ityalwe ngqo egadini ukuze ikhule kakuhle. Ukumelana nokubanda ukuya kwi -2ºC.
Izityalo ezinedicotyledonous
Lelona qela liqhelekileyo kwii-angiosperms, kakhulu kangangokuba kukholeleka ukuba kukho malunga ne-200.000 yeentlobo. Kuzo, umbungu ongaphakathi kwembewu ukhupha ii-cotyledon ezimbini xa zihluma, ezingamagqabi amabini akudala anokusebenza njengokutya kwesithole esitsha. Nje ukuba ikhule, amagqabi ayo afumana iimilo ezahlukeneyo: ezimilise okwentliziyo, ezinamakhasethi, ezinomphetho ocoliweyo okanye olula ...
Ngokungafaniyo ne monocot, ingcambu evelayo kwakamsinya nje ukuba ihlume, iyaqhubeka nokukhula njengengcambu ephambili. Kwaye enye inkcukacha ebalulekileyo: ukuba usike isebe, uya kuyibona kwangoko imisesane yonyaka, eyenziwe ngu xylem kunye ne-phloem. La masebe, kunye nesiqu, Unokubamba ngokuqamba iinkuni okanye iinkuni.
Ngaphakathi kolu hlobo lwezityalo, sifumana imidumba, iRosaceae, iRutaceae, phakathi kwezinye ezininzi. Eminye imizekelo yile:
I-Acer sp (Imephu)
Enye yeentlobo ze Imithi enqabileyo kunye nezihlahla olinywa kakhulu kuzo zonke iingingqi ezinemozulu epholileyo. Zisasazwe kuMntla Merika, eYurophu, eAsia nakuMntla Afrika, kukholelwa ukuba ziintlobo ezili-160, ezona zaziwayo zezona Acer palmatum (Imephu yaseJapan), i I-Acer pseudoplatanus (maple wobuxoki), kwaye i Iarcer yerum (imephu ebomvu), phakathi kwabanye.
Bonke bafuna imozulu epholileyo, ehlotyeni akukho kushushu kakhulu (ubuninzi be-30ºC) kunye nobusika obubandayo (ubuncinci be -15ºC).
IBouganvillea sp (iBougainvillea)
Yiyo isityalo esinyukayo yemveli kwimimandla yetropiki yoMzantsi Merika enokufikelela kwiindawo eziphakamileyo ukuya kuthi ga 12 mitha. Ayinayo imisipha, kodwa izikhondo zayo zixinene ngokusebenzisa ameva abukhali. Ngentwasahlobo nasehlotyeni zivelisa umboniso we-inflorescence, ipinki, orenji okanye mhlophe kuxhomekeke kudidi.
Ingakhuliselwa ngaphandle kwimozulu ethambileyo, kunye neqabaka ukuya kuthi ga -2ºC.
URosa sp (uRosales)
Ziyenye yezona zihlahla ezintle kakhulu ezikhoyo. Abomdabu baseYurophu, eMntla Melika, nakumntla-ntshona weAfrika, kukho iintlobo ezili-100 eziqikelelweyo kunye nemilimi engenakubalwa kunye neembumba. Kulula kakhulu ukukhathalela izityalo, zifuna ukunkcenkceshelwa rhoqo, ukuthena rhoqo (Ngaphezu kwako konke, susa iintyatyambo ezibunileyo), nelanga elininzi ukuxabiseka.
Kwaye ukuba oko akwanelanga, bachasa ukubanda kakuhle kunye neqabaka ezantsi ukuya -5 -C.
Ngaba ukhe weva ngezityalo ezinemonocotyledonous kunye nedicotyledonous?
Molo uMonica okanye abanye abafundi:
Ndifuna ukufumana imbewu yemifuno (ayikhethi bodwa) kodwa ayiyiyo i-hybrid okanye i-transgenic.
Gracias
Molo Pancho.
Uya kuyifumana imbewu oyikhangela kwiindawo zokugcina ukutya okanye kwiivenkile zezolimo. Zithengiswa ezingxoweni, njengembewu yendalo.
A ubingelele.
Molo, unjani Monica? Ndinombuzo.
Zithini izityalo ezivela kwithambo okanye imbewu njengehlumelo elincinane elibizwa? ezifana nee-ahuacates, ii-lychees, ii-mangos kunye nama-walnuts.
Molo uFranco.
Zizityalo ezinamachaphaza amade. Ezi cotyledon zimbini, oko kukuthi, amagqabi amabini okuqala, zizinto zokuqala ukubonwa xa imbewu ihluma. Kwezinye iintlobo ezi zihlala phantsi komhlaba kwaye zibola ngokukhawuleza xa kuvela amagqabi okwenene okwenene.
A ubingelele.
Molo uBladimir.
Phantse zonke iintyatyambo zi-dicotyledonous: i-geraniums, i-pansies, i-petunias, i-hibiscus, ... ewe, phantse naziphi na iintlobo ezineentyatyambo ezithandekayo.
Zine-dicotyledonous kuba xa imbewu ihluma, kuvela ii-cotyledon ezimbini, ezaziwa ngokuba ngamagqabi okuqala.
A ubingelele.
Molo Monica, ndinombuzo
Izityalo ezi-Monocotyledonous imbewu yazo aziveli emhlabeni, ndingathanda ukwazi ukuba kutheni
Molo Jazmin.
Uxolo, andiwuqondanga umbuzo wakho. Uthetha ukuba abahlumi njengamachaphaza?
Umzekelo, amasundu athwala isiqhamo ukuya ehlotyeni. Ukuba iimeko zilungile, nje ukuba ziwele emhlabeni ziya kuhluma ngeentsuku ezimbalwa (iintsuku ezi-3-7).
A ubingelele.
Ndizifumana zinomdla iingcaciso
ukuqonda ukuba zeziphi izityalo
Siyavuya ukuba uyifumene inomdla., UMiranda
