Yiziphi izitshalo ezi-dioecious ne-monoecious

Lapho sifuna ukutshala izitshalo zethu ngokuthola imbewu kule mifino efanayo, kufanele sinake ukuthi zikhula kanjani ngokwemvelo; okungukuthi, yiziphi izimbali ezinezimbali zazo ukuvumela ukukhula kwesizukulwane esisha.

Ngakho-ke, engadini kubaluleke kakhulu ukwazi yiziphi izitshalo ezi-dioecious ne-monoecious, ngoba ukwazi impendulo yakho kuzosisindisa ngaphezu kwekhanda elilodwa.

Ziyini izitshalo ze-dioecious?

Izitshalo ezihlukanisayo yizo esishiya kancane kancane, ngeshwa, kancane eceleni ngoba azizuzi kakhulu. Yilezo ezihlukaniswa phakathi kwama-specimens wesilisa nowesifazaneNgakho-ke, ukuze ukuvundisa kwenzeke, impova yangaphambili kufanele ivundise i-ovary etholakala ezimbalini zakamuva.

Izibonelo

I-actinidia emnandi

I-Kiwi isitshalo esikhuphukayo esingahle sifinyelele kumamitha ayi-9 ukuphakama. Amaqabunga acishe abe ngu-7,5 kuye ku-12,5cm ubude, kanti zikhiqiza izimbali ezinamacembe aphuzi ayisi-5-6, nangama-stamens amaningi, yize lezo zesifazane zingenayo impova esebenzayo.

ICycas revoluta

Saziwa njenge-cica, i-palm palm noma i-king sago, siyisitshalo esikwazi ukukala amamitha ayi-6-7 futhi sinesiqu esingaphezu kwamasentimitha angama-30 ukushuba. Amaqabunga aluhlaza okotshani, nobude obuphakathi kwamasentimitha angama-50 kuya kwayi-150. Zikhiqiza ama-inflorescence okuthi, ezimweni zezinhlobo zesilisa, zinde futhi ezimweni zesifazane, zizungezwe futhi zihlangene..

Ginkgo biloba

Yaziwa njenge-ginkgo noma umuthi wezihlangu ezingamashumi amane, futhi ingenye yezinsalela eziphilayo ezithandwa kakhulu emhlabeni. Yisihlahla esinqumayo, esinokuphakama okungaba ngamamitha angama-35, esiba nomqhele othize wepiramidi. Ama-specimens wesilisa anama-inflorescence aphuzi aqoqwe kuma-catkins, kanti awesifazane akhiqiza izimbali eziqoqwe ku-2-3.

IPersea americana

Ukotapeya noma ukotapeya isihlahla esihlala siluhlaza esingavamisile ukudlula i-12 (yize endle sifinyelela ku-20m), esinomqhele oyindilinga ongaphezulu noma omncane owakhiwe ngamanye amaqabunga ka-2 kuye ku-5cm. Ama-inflorescence ama-panicles akhiwe ngezimbali eziyi-5-6mm, ngombala ophuzi.

IPistacia Vera

Yaziwa ngokuthi yi-pistachio noma i-alfóncigo, futhi iyisihlahla esinqumayo esifinyelela kumamitha ayi-10 ukuphakama namaqabunga e-pinnate amasentimitha ayi-10 kuye kwangama-20 ubude. Izimbali azinawo amacembe futhi zibuthene ngamaqoqo, iba bomvu njengabesifazane kanye nabesilisa baluhlaza-phuzi.

Ziyini izitshalo ze-monoecious?

Izitshalo ezi-monoecious zithola indawo ngaphezu kwe-dioecious, okungenani ezingadini nasezingadini. Yimifino leyo wethule izitho zowesilisa nowesifazane esitezi esisodwa. Kunezinhlobo ezintathu:

• I-Monocline-monoecious: bethula izinto zokuzala embali efanayo, njengeTulipa sp (tulip).
• I-Diclino-monoecious: isitshalo esifanayo sinezimbali zesilisa nezimbali zesifazane, njenge Zea mays (ukolweni).
• Ama-Polygams: isitshalo esisodwa sinezimbali ze-hermaphroditic nezingabulili obufanayo, njenge UCarica papaya (i-Papaya).

Izibonelo

I-Acer opalus

Yaziwa ngokuthi i-orón noma i-asar, futhi iyi-maple enqabayo efinyelela amamitha angama-20 ukuphakama nesiqu esifinyelela kumitha elilodwa ububanzi. Umqhele wenziwe ngamahlamvu esundu aluhlaza awu-1 kuya ku-7cm ubude ngo-13-5cm ububanzi aphenduke abe bomvu ekwindla ngaphambi kokuwa. Izimbali zincane futhi ziphuzi.

ICocos nucifera

Isihlahla sikakhukhunathi ngumuthi wesundu onesiqu esisodwa ongalinganisa kusuka kumamitha ayi-10 kuye kwangama-20 ukuphakama, ngamaqabunga we-pinnate amamitha ayi-3-4 ubude. Izimbali ziqoqwe kuma-inflorescence aqhuma kuma-axils amaqabunga aphansi, ezivikelwe yi-spathe noma i-bract engamasentimitha angama-70 ubude.

I-Eucalyptus

I-Eucalyptus izihlahla ezihlala ziluhlaza ezikwazi ukufika kumamitha angama-60, futhi kutholakale nezinhlobo zamamitha ayi-150. Amaqabunga yi-ovate futhi ampunga, aqhuma emagatsheni aqhamuka esiqwini esiqondile. Zikhiqiza izimbali ezimhlophe, eziphuzi noma ezibomvu, ziqoqwe kuma-inflorescence.

Ziyini izingxenye zembali?

Ukuthola ukuthi ngabe imbali iyiduna, insikazi noma i-hermaphrodite, kuzokwanela ukuthi sibheke ukuthi une-androecium (ingxenye yowesilisa), kanye / noma i-gynoecium (ingxenye yabesifazane). Zonke izitshalo eziqhakazayo zinezingxenye ezithile ongazibona esithombeni esingenhla, ngakho-ke ngalesi sithombe ukwazi kalula futhi ngokushesha ukuthi hlobo luni lwesitshalo onalo.

Ngiyethemba ibilusizo kuwe.
