Maruva miti

Nemiti Pasi mupfumi uye siyana. Asi pane imwe zvachose rakasiyana boka - maruva zvirimwa. Zvinosanganisira marudzi mazana maviri namakumi mashanu nezviviri akasawana redu, kubvira kumuduku mhenyu mumvura uye duckweed miti makuru, yokusvika nekukwirira pamusoro 90 mamita. Muchiitiko chino, nemiti yakabva kune dzimwe vane Woody madzinde miriwo vane mutete manune hunde.

Nhengo kuti maruva zvinomera zviri rakakamurwa mapazi muviri uye kubereka. Kuburikidza midzi, madzinde Mashizha chirimwa nderekugamuchira simba. A maruva nemichero kuita chaizvo basa - kubereka chaitika.

A pachena kuchiitwa boka iri miti ndiyo kuvapo imwe nhengo dzokubereka nadzo - ruva. Zvinogona wakajeka uye akanaka zvinoshamisa, dzakaonda angava kusimba hunonhuhwira, uye tifanane pauswa, kuva diki uye asazivikanwa.

Chero ruva chinosanganisira akawanda zvikamu, chimwe nechimwe anoita yakananga basa. Sepals - rokunze chikamu, iyo inodzivirirawo muviri vachiri chipande pachikuva. Chinonyanya chinoshamisa ndechokuti ruva petals inobwinya ruvara uye hwema kukwezva nezvipembenene zhinji. Mukume tsanga ndiwo mudziyo nokuda gono utachiona masero uye dzakabatana Stamens. Mukume kubva chirimwa kudyara anotamisa kana mhepo kana nezvipembenene. Ovary - mudziyo nokuti munhukadzi pabonde masero. Pakusangana mu maruva miti inogona chete kuitika kana unobatanidza mukume zviyo pamwe ovary. Kazhinji, zvirimwa izvi vane ovaries uye Stamens imwe ruva. Separate vechirume maruva zvakaparadzana kuitika nomuzvarirwo mu maruva aya zvinomera, zvakadai pemioki kana the willow.

Pfungwa photosynthesis kuitika mashizha, ndiye kutendeuka carbon dioxide inobvisa uye mvura pasi pokudzora rezuva simba iri muviri. Magwaro Feeds maruva zvirimwa. By madzinde, izvo zvinoumba nomuzongoza yose muviri sezvo zvibereko, kubva pamudzi kusvikira mashizha mvura inopinda. Roots uyewo kuita rakasiyana basa; ivo vanochengeta kunzwisisa mamiriro miti kuburikidza tsvimbo, kuvakoka zvakadzama, uye duku spines, zvakajairika pedo pemvura ivhu, uyewo mushoma mvura uye zvicherwa kubva pakadzika pasi.

Pakusangana kuti maruva miti iri sezvinotevera: zai uye mukume chokuita, uye ovaries vari akaumba mbeu. Kusvikira zvadai chirongwa pollination. Mukume iri achichinjwa ruva kuti kana mhepo kana nyuchi, kungozvifunga uye zvimwe zvipembenene. Kusimba munuhwi uye yakajeka ruvara ruva chinokwezva mukume. Kwavari, mujinga ari petals anounganidza inotapira nekita. Mune kunotsvaka sugary zvokudya, mukume tsanga kuomerera mudumbu, makumbo, mapapiro ane Tupukanana, uye sezvo izvi zvinozipa zino hakugumiri kushanyira rimwe ruva, mukume anowira nyore kune vamwe. Flowering miti zvibereko hombe yakawanda mukume, iyo achaendeswa nemhepo, uye sirika maruva zvokukutapukira ari mambure.

Panongotanga mukume tsanga kuwa kubva ruva kuti ruva, hairuki ducts diki kuti usvike kune ovaries, batanidza vanhurume masero nevakadzi. Saka zai, umo mbeu zviri aumba. Zvichakadai, ovary inokura, achiumba zvibereko (michero, nzungu, akaoma mabhokisi).

Kana upenyu kutenderera maruva miti inogona kuva gore negore, biennial uye perennial. With pagore nyore: anotumbuka kamwe chete uye kufa, zviri zvose kuitika mukati gore rimwe. An mufananidzo kunakidza rakazaruka riri vachiongorora zviri biennials. In kwavo gore upenyu wokutanga chinoshingaira kukura madzinde mashizha, uyewo kuunganidza nemidzi muviri. Yakanga chete mugore rechipiri anoshandisa mudzi mumatanda muviri nokuda DISTILLATION pamusoro matavi kuti zvichaita ruva pakutanga, achabereka zvibereko, uye ipapo wasvava. Perennial plants anotumbuka kwemakore akawanda, tichifadza isu maruva akanaka.
