Zomera zonse m'chilengedwe zimakhala ndi zosiyana zawo. Malingana ndi kugawidwa kwa amuna ndi akazi, mitundu yonse ya zomera imagawidwa m'magulu otsatirawa:
- zokopa;
- wachinyamata;
- ophatikiza ambiri.
Zomera zam'madzi ndizomwe zimakhala ndi maluwa achikazi kwa anthu ena ndi maluwa amphongo kwa ena. Kuuluka kwawo kumachitika modutsa. Chifukwa chake zipatso za mitengo ya dioecious zimangirizidwa ngati mungu wa anthu ochokera maluwa amphongo asamutsidwira kumitengo yokhala ndi maluwa achikazi. Izi sizikanatheka popanda njuchi, zomwe zimayendetsanso pollination. Chosavuta cha chida chonga dioeciousness ndikuti mbewu sizipezeka mu 50% ya zomera zamtundu winawake. Mwachilengedwe, palibe mitundu yoposa 6% yamtunduwu yomwe imapezeka. Izi ndi izi:
Msondodzi
Sorelo
Mistletoe
Laurel
Nettle
Popula
Hemp
Yambani
Kusiyana pakati pa amuna ndi akazi
Kusiyanitsa pakati pa amuna ndi akazi mitundu ya dioecious nthawi zonse kumakhala kovuta, iwo omwe amalima maluwa, mitengo ndi mbewu zina ayenera kuphunzira kudziwa kugonana. Maluwa a amuna ali ndi stamens yodzaza ndi mungu, ndipo malingaliro awo samakula. Maluwa achikazi nthawi zambiri amakhala opanda stamen.
Ngati mtengo m'munda sungabale zipatso, ndiye kuti ndi wamtundu wa dioecious. Kuti muthane ndi vutoli, muyenera kubzala pafupi mtundu wake chomera cha mtundu womwewo, kenako chifukwa cha njuchi zomwe zimathandiza maluwawo kuti apange mungu, mtengowo uyamba kubala zipatso.
Male maluwa dioecious zomera zambiri mungu zambiri. Izi ndichifukwa choti akazi samakula nthawi zonse pafupipafupi, zomwe zikutanthauza kuti payenera kukhala mungu wokwanira wochitira mungu mbewu zachikazi zomwe zikukula. Ndi yopepuka ndipo imatha kufalikira kumadera akutali ndi mphepo yamkuntho.
Kodi kuphulika kwa dioecious kumachitika bwanji?
Mkuyu ndi chomera cha dioecious, ndipo pachitsanzo chake tiona momwe mungu umayendera. Ili ndi maluwa ang'onoang'ono komanso osadabwitsa. Kuyendetsa mungu kumachitika chifukwa cha mavu ophulika. Mkazi wamkazi wamtundu uwu amayang'ana maluwa achimuna pomwe mavu amphongo amakhala. Chifukwa chake, mavu amatenga mungu kuchokera kumaluwa amphongo ndikuwononga maluwa aakazi achikazi. Chifukwa chake umuna umapezeka mu mavu, ndipo chifukwa cha iwo, maluwa a mkuyu ali ndi mungu.
Dioeciousness ndimasinthidwe apadera a zomera, zomwe zimawonekera poti mtundu umodzi uli ndi akazi ndi amuna, koma nthawi zambiri zimakhala zovuta kudziwa kugonana kwawo. Zikatero, obereketsa amayesa kubzala mitundu yatsopano yamtundu umodzi kuti m'tsogolo muno wamaluwa asadzakhale ndi vuto ndi chonde.
