Ruva unonzi dzakachinjwa chirimwa mabukira, dzaizopiwa ruminant mbeu. Kusiyana matavi Muzvarirwo (mabukira), anova kubva ruva maruva. Hunde yacho ruva riri pedicel uye mudziyo. Corolla, Calyx, Stamens uye pistils dzakachinjwa mashizha aumba. Kuti tinzwisise nei tichida chirimwa mitumbi zvose izvi zvinofanira kuongorora muudzame sechivako nomumwe ruva. Saka, panguva yayo pakati ndiye pistil, iyo, pasinei zita raro, ari "munhukadzi" pamuviri nenyere. Kazhinji, rakapoteredzwa izhinji stamen, izvo "munhurume" pamuviri nenyere. Chero ruva stamen uye pistil - huru chikamu. Of pavo zvichaita vakazoroorwa aumbwa michero chirimwa ane mbeu ndivo yakavimbika nzira kubereka.
Stamen uye pistil kutamba inokosha basa muupenyu maruva zvinomera. Male pabonde nhengo vamwe ruva, inova muunganidzwa ose Stamens, rinonzi "androecium". Mumwe nomumwe wavo ane "Staminate shinda" uye 4 "pakati mukume zai," vasungwa "duster". Inoitwa sezvikamu zviviri, chimwe nechimwe, akavapindurawo, pane in maviri (makamuri kana nezvigadziko). Ivo akaumba zvose anozivikanwa mukume. Maererano staminal filaments akabata mvura uye zvokudya. Female pabonde nhengo ruva iri "gynoecium", izvo, chokwadi, inonzi "nomutswi". It rine "mbiru", "ovaries" uye "rusarura". On ichi "kunongedza" uye chinozadzwa kuibva nepfuma pamusoro Stamens. "Column" anoita rutsigiro mashandiro, uye "ovary", ine ovules (imwe kana kupfuura) kukura mbeu panosangana. The ovules vari mudumbu SACS, dziri kukura nokukurumidza uye zvirimwa fomu muchero. Pistil uye stamen, zano vasingadi kuva kwakakwana pasina "nectary", emitting chinonhuhwira nekita, kazhinji kuwana mukume nezvipembenene, bhururuka kubva ruva kuti maruva. Perianth rine Corolla uye Calyx. Pistil uye stamen vakakomba perianth.
Pane zvakawanda zvakasiyana siyana nemaruva, izvo zvinokonzerwa kuvapo avo kana dzimwe nhengo. Saka, zvinomera iro maruva vane pistil uye Stamens, vari "zvepabonde nevarume uyewo nevakadzi." Kana paine chete Stamens kana pistils chete - chirimwa anonzi "dioecious". "Monoecious" raireva avo nemiti, izvo wakapindwa maruva uye Stamens, uye pistils pamwe. "Dioecious" zvinomera vanonzi, ndine chete pistillate kana maruva staminate chete.
The nemamiriro pistil uye Stamens vakaumba mamiriyoni emakore. Ruva ndiyo okubereka nhengo angiosperms. Stamen uye pistil zvinopa chirimwa inotungamirwa zvibereko (mbeu). The muchero anooneka nedanho Fusion kuti carpel. Iye nyore (pizi, plums, Cherry) kana kunzwisisa (zvinosanganisira vanoverengeka fused pistils - ruva, seruva, cornflower). nhengo dzakawanda nemiti vari undeveloped (wokugaya) pistils. Species kusiyana mune mhando uye mamiriro maruva nokuda yomuka mukufamba kwenguva shanduka kusiyana matongero avo pollination.
