Izityalo dioecious: iimpawu kunye namanqaku anika umdla

Izityalo ukuba amalungu ngokwesini - inkunzi nemazi - is izityalo dioecious. Imizekelo ezinjalo izityalo - umba, poplar, yemibhaka (yemibhaka), hlaza, isipinatshi, willow, hemp, zepistasi, Podocarpus kunye nabanye. Kodwa oku asikokuphela kwayo.

Kwaye zonke izityalo neentyatyambo dioecious, kodwa ezinye ziya kuba 'yindoda' iintyatyambo, ngoxa abanye - "ababhinqileyo". Kuba iintlobo enjalo flora imifuziselo iLayibhrari yaMaxwebhu. Monoecious kunye nezityalo dioecious zahluke ukuba yangaphambili abe 'yindoda' yaye 'nenkazana "iintyatyambo kwisityalo efanayo.

Uvuvuzelo kwezityalo dioecious

isityalo Dioecious ukusuka kwindawo Ngenxa kwemvelo zithathwa ukuba ibe phambili ngakumbi. Ukuba abanako ukuzeyisa yaMaxwebhu, kwaye le nto inegalelo kwiintlobo.

Kuba abathile imithi yeziqhamo kubalulekile ukuba nobudala. Xa inkqubo ifakwe, kunye nokuveliswa iimbewu kunye neziqhamo tychinkovyh umungu kweentyatyambo eyindoda athathe ibala yabafazi. Kuphela kulo mzekelo uyakwazi ukufumana iziqhamo. Kodwa ke oku akuthethi ukuba ngamnye izityalo "libhinqa" kufuneka ukuba umthi omnye wesini esahlukileyo.

ummeli omnye wesini obudoda ziya kusetyenziselwa uvuvuzelo ye inani lezityalo ababhinqileyo. Inombolo eyiyona kuyahlukana nedlela uhlobo lwesityalo. Umzekelo, ukuba ukuchumisa yonke Ashera wamasundu umhla watyala derevev- ezimbalwa "eyindoda". Yanye inkunzi umthi umhla neentende ngokwaneleyo yokusasaza 40-50 imithi besini esahlukileyo. Amaxesha amaninzi, ukuze kuqinisekiswe uvuvuzelo ngempumelelo kwi imithi basethyini ingabo ukumiliselwa isebe lomthi eyindoda.

Umahluko phakathi kwabo izityalo ezifanayo

Amaxesha amaninzi ekuqaleni kunzima ukumisela ukuba ngokukokwam ekhaya izityalo. Kodwa uyayeka ukuba lilungu imfihlelo xa kufikwa lokuvuna lokuqala - iziqhamo ziya kuba phezu nemazi. Ngelo lixa umahluko obonakalayo kuzo ubume iintyatyambo inkunzi nemazi. Iduna ibala encinane ngophuhliso okanye hayi, ukanti stamens intyatyambo obhinqileyo ukuba ulahlekile. Stamens kwi amablom obufazi phantse akafuneki ukuvelisa umungu, lo gama stamens eyindoda iintyatyambo oluphahlwe kakhulu nayo.

Ukufundiswa Isicelo kolwazi izityalo dioecious

Ukulungiselela iinjongo ezithile, kubalulekile ukwazi apho izityalo dioecious, kodwa kwakhona ukukwazi ukwahlula besini zezohlobo olufanayo. Umzekelo, ukuba iya kuba umthi yemibhaka ongavelisi siqhamo, kungenzeka, kuba umthi eyindoda. Kwaye lokonwabela amaqunube okunencasa kwaye usempilweni, kufuneka ubeke isibini kuye - umthi ababhinqileyo. Okanye ubuncinane ukubethelela kwisebe nemazi komthi. Kwelinye icala, isebe nemazi komthi ukubethelela into eyindoda.

Ngelo xesha, ukuba ufuna ukuthenga kuba yemibhaka ebaleni kuphela ngeenjongo zokuhombisa, kungekhona ukuba ahlale ukucoca phantsi emhlabeni amaqunube overripe, kungcono ukukhetha umthi oyindoda - it nesithsaba sokuhomba oluchumileyo, kodwa soze athwale isiqhamo.

Izityalo ezi dioecious, ingakumbi, abameli oyindoda, ukuvelisa iimali elikhulu umungu. Le nyaniso ilula kakhulu kwaye singabi ingcaciso ubhalo emthini amaqanda jikelele, ngoko ke umungu kufuneka ibe kakhulu, khon 'ukuze ifikelele usukelo lwayo. imithi Male ukuvelisa umungu ngakumbi, amasuntswana kuyo ukukhanya kakhulu kwaye ube imilo eyenza kube lula ukuba 'maza "kwi nomoya.

Amakhiwane - isityalo esithile dioecious

Amakhiwane, ebizwa nkqu umkhiwane okanye amakhiwane - enye abameli ezininzi umdla dioecious. Kucingwa izityalo omdala ezilinyiweyo. Ngokukhankanywa umthi womkhiwane kukuthi, nkqu eBhayibhileni.

Umthi womkhiwane ayahlukanga esezansi ezintle - iintyatyambo amakhiwane mincinci kwaye zokuqhubela. Kodwa le nokubi uyahlawulwa azinamanzi nobusi ukuze uxhamle iziqhamo. Noko ke, kuphela izityalo ababhinqileyo bangavelisi siqhamo. Ngoko ke, ezivela imbewu amakhiwane zomthi kuba, njengoko bathi, iqokobhe engenanto, oko kukuthi, lo mthi eyindoda. Kodwa ngaphandle apho kuya kubakho iziqhamo kunye nemithi ababhinqileyo.

amakhiwane uvuvuzelo - yinto esinomdla isihloko kakhulu isifundo esahlukileyo. Isibakala sokuba iintyatyambo umkhiwane ukuba ezimvumvuzelwa kuphela noonomeva blastofagi. noonomeva oyindoda zingenamaphiko elinde imazi ngaphakathi imbali eyindoda. I ayaqhama female-blastofaga ziqokelela umungu kwi yayo ivuthuluke umzimba eyindoda, ukuphuma kulo, bejonge inflorescences ezintsha iinkunzi athwale umungu kwi amablom obufazi.

anika umdla

Izazinzulu ziye zafumanisa ukuba impilo yabantu, sinotyekelo komzimba, Izityalo dioecious iyingozi kakhulu. Phakathi kwazo zizityalo eqhelekileyo kakhulu allergenic. Kwaye abo bazakhele isidima zamavumba kakhulu nazo dioecious. Kodwa, ukukhetha izityalo ukuze yolwabiwo, awukwazi ukunika up on kwisityalo dioecious, kufuneka nje ukuba zincede zikhethe iimazi - ayivezi izixa enjalo umungu, zombini inkunzi kuthetha nempembelelo encinane kuloo mntu.

Phantsi kwemiqathango ethile egwenxa izityalo dioecious, ezifana hemp, isenokubangela monoecious. Ngelo xesha kwi isityalo efanayo ukuyihambisa yinkunzi kunye amablom obufazi.

Kumaxesha amandulo, ngokubanzi ulwazi loko izityalo dioecious. Imizekelo yalo ingafumaneka nkqu kwimbali izidubedube emkhosini. Ngokomzekelo, abantu ngexesha behlasela kwamanye amazwe batshabalalisa amadoda entendeni Ashera - kube lula kakhulu kunokuba wazigawula ngokupheleleyo phantsi zonke izithuba, kodwa nokuqinisekisa ukuba akukho isityalo ukulahleka ezibalulekileyo lwezoqoqosho kurhulumente.
