Zithini izityalo ezinamachamo amdaka

Xa sifuna ukuzikhulisela ezethu izityalo ngokufumana iimbewu kwezi imifuno inye, kufuneka sithathele ingqalelo indlela eziphindaphindeka ngayo ngokwendalo; Oko kukuthi, zeziphi izitho ezinazo iintyatyambo zazo ukuvumela ukukhula kwesizukulwana esitsha.

Ke ngoko, kwigadi kubaluleke kakhulu ukuba uyazi ziziphi izityalo ezi-dioecious kunye ne-monoecious, kuba ukwazi impendulo yakho kuya kusisindisa ngaphezulu kwentloko enye 🙂.

Zithini izityalo zedioecious?

Izityalo ezinobungozi zezi zinto kancinci kancinci sizishiya, ngelishwa, ecaleni kancinci njengoko zingenanzuzo kakhulu. Zizo ezo zahlulwe phakathi kwesampulu yamadoda neyomfaziKe ngoko, ukuze isichumiso senzeke, umungu wangaphambili kufuneka uchumise i-ovary efumaneka kwiintyatyambo zamva nje.

U mzekelo

Actinidia emnandi

I-kiwi sisityalo esinyukayo esinokufikelela kwiimitha ezili-9 ukuphakama. Amagqabi amalunga ne-7,5 ukuya kwi-12,5cm ubude, kwaye zivelisa iintyatyambo ezinamagqabi atyheli ama-5-6, kunye ne-stamens ezininzi, nangona ezo zimazi zingenayo impova.

Ungasinyamekela njani isityalo se kiwi

Icycas revoluta

Yaziwa njengecica, ubuxoki besundu okanye inkosi sago, sisityalo esifikelela kwiimitha ezi-6-7 ubude kwaye sinesiqu esingekho ngaphezulu kweesentimitha ezingama-30 ubukhulu. Amagqabi aluhlaza ocacileyo, anobude obuphakathi kwe-50 ukuya kwi-150 yeesentimitha. Bavelisa ii-inflorescence ezithi, kwimeko yeesampulu zamadoda, zinde kwaye kwimeko yabasetyhini, zirhangqiwe kwaye zincinci..

Inqaku elidibeneyo:

ICica

Ginkgo biloba

Iyaziwa njenge-ginkgo okanye umthi wamakhaka angamashumi amane, kwaye yenye yezona zinto zaziwayo ehlabathini. Ngumthi onqabileyo, onobude obumalunga neemitha ezingama-35, ovelisa isithsaba esithile sepiramidi. Iisampulu zamadoda zinee-inflorescence ezityheli eziqokelelwe kwiicatkins, kwaye ezasetyhini zivelisa iintyatyambo ezidityaniswe ngo-2-3.

Inqaku elidibeneyo:

UGinkgo biloba okanye uMthi wee pagodas, ifosili ephilayo

IPersea americana

Iavokhado okanye iavokhado ngumthi ohlala uluhlaza ongadluli kwi-12 (nangona endle ufikelela kwi-20m), unesithsaba esingaphezulu okanye esincinci esenziwe ngamagqabi e-2 ukuya kwi-5cm. Ii-inflorescence zii-panicles ezenziwe zii-5-6mm zeentyatyambo, zimthubi ngombala.

Inqaku elidibeneyo:

Ukothuka (Persea americana)

IPistacia Vera

Yaziwa ngokuba yi-pistachio okanye i-alfóncigo, kwaye ngumthi onqabileyo ukuya kuthi ga kwi-10 yeemitha ukuphakama kunye namagqabi e-pinnate ali-10 ukuya kuma-20 eesentimitha ubude. Iintyatyambo azinawo amagqabi kwaye ziqokelelwe ngokwamaqela, ukuba bomvu bomfazi kunye nobudoda obuhlaza-tyheli.

Zithini izityalo ezinemonoecious?

Izityalo ezi-monoecious zifumana umhlaba ngaphezulu kwe-dioecious, ubuncinci kwizitiya nakwiigadi zeziqhamo. Yimifuno leyo thaca izitho zesini nesini kumgangatho omnye. Zintathu iintlobo:

• Imonocline-monoecious: baveza izixhobo zokuzala kwintyatyambo enye, njengeTulipa sp (tulip).
• I-Diclino-monoecious: isityalo esinye sineentyatyambo zesilisa neentyatyambo zabasetyhini, ezinje nge Zea amaxesha (umbona).
• Isithembu: Isityalo esinye sineentyatyambo ze-hermaphroditic kunye ne-unisexual, ezinje nge UCarica papaya (ipapaya).

U mzekelo

i-acer opalus

Yaziwa ngokuba yi-orón okanye i-asar, kwaye iyi-maple enqabileyo efikelela kwiimitha ezingama-20 ukuphakama kunye nesiqu ukuya kuthi ga kwimitha enye ubukhulu. Isithsaba senziwe ngamagqabi aluhlaza wesundu ama-1 ukuya kwi-7cm ubude nge-13-5cm ububanzi ajika abe bomvu ekwindla ngaphambi kokuwa. Iintyatyambo zincinci kwaye zityheli.

Inqaku elidibeneyo:

i-acer opalus

ICocos nucifera

Umthi wekhokhonathi ngumthi wesundu one-stem omnye onokulinganisa ukusuka kwi-10 ukuya kwi-20 yeemitha ukuphakama, kunye namagqabi e-pinnate ama-3-4 eemitha ubude. Iintyatyambo ziqokelelwe kwii-inflorescence ezihluma kwii-axils zamagqabi asezantsi, ezikhuselwe sisiporho okanye ibract ye-70 yeesentimitha ubude.

Inqaku elidibeneyo:

Umthi wekhokhonathi (Cocos nucifera)

Eucalyptus

Imithi yeEucalyptus yimithi ehlala iluhlaza enokufikelela kwiimitha ezingama-60, kwaye kuye kwafunyanwa iisampulu zeemitha ezili-150. Amagqabi yi-ovate kwaye angwevu, aphuma kumasebe avela kwisiqu esithe nkqo. Bavelisa iintyatyambo ezimhlophe, tyheli okanye bomvu, zibekwa ngokwamaqela kwii-inflorescence.

Inqaku elidibeneyo:

I-Eucalyptus (i-Eucalyptus)

IPrunus dulcis

Eyaziwa ngokuba ngumthi wom-amangile, sisihlahla esinqumlayo okanye umthi ukuya kuthi ga kwiimitha ezi-5 ukuphakama kunye namagqabi alula kunye ne-lanceolate ayi-7,5 ukuya kwi-12,5 cm ubude. Iintyatyambo zizodwa okanye zibonakala zingamaqela, kwaye zenziwe ngamagqabi amahlanu amhlophe okanye apinki.

Inqaku elidibeneyo:

Umthi wom-amangile, umthi omhle wegadi

I-Quercus ilex

Yaziwa njenge-oki emfutshane, emfutshane okanye eluhlaza okwexeshana efikelela phakathi kwe-16 ukuya kwi-25 yeemitha ukuphakama. Isithsaba sayo sijikeleziwe, sinamagqabi aluhlaza amnyama. Iintyatyambo ezingamadoda ziintyatyambo eziorenji okanye zimdaka ngombala, kwaye ezamabhinqa zincinci, zodwa okanye zingamaqela amabini., o-orenji-tyheli ngombala.

Inqaku elidibeneyo:

Um-oki weHolm (Quercus ilex)

Athini amalungu entyatyambo?

Ukufumanisa ukuba intyatyambo yindoda, ibhinqa okanye i-hermaphrodite, Kuya kwanela ukujonga ukuba unayo na androecium (inxenye yamadoda), kunye / okanye i-gynoecium (inxalenye yabasetyhini). Zonke izityalo zeentyatyambo zinezinye zeendawo onokuzibona kumfanekiso ongentla, ke ngalo mfanekiso unokwazi ngokulula kwaye ngokukhawuleza ukuba loluphi uhlobo lwesityalo onaso.

Ndiyathemba ukuba iluncedo kuwe.
