Chii chinonzi hermaphrodite ruva?
Ruva rehermaphrodite iruva rine nhengo dzekubereka dzechirume nedzechikadzi mumunhu mumwe chete. Nemamwe mashoko, ruva rehermaphrodite rinokwanisa kuzviberekesa roga uye kubereka mbeu pasina chikonzero chekusvina maruva nemamwe maruva.
Kugadziriswa uku kunovabvumira kuona kuti mhando dzembeu dzinogadzirwa uye kuti dzinorarama kunyangwe pasina dzimwe mhuka dziri pedyo dzekuti dzibatane nadzo. Izvi zvinogonawo kuva nzira yekuchengetedza simba nezviwanikwa, sezvo zvisingade kugadzirwa kwemukume wakawanda kana kutsvaga mukume wemukume.
Muzvisikwa, zvirimwa zvakawanda zvinomera zvakasiyana-siyana, kusanganisira mamwe marudzi emiti, shrub, herbs, uye cacti. Kunewo marudzi mazhinji emiti inorimwa ine mhando dzakasiyana-siyana, dzakadai sesquash, watermelon, uye mamwe marudzi edomasi. Kunyangwe zvisingawanzoitiki, mamwe marudzi eorchids nemaruva anogonawo kuva akasiyana-siyana. Tichakurukura mimwe mienzaniso gare gare.
Hunhu hweruva rehermaphrodite
Hunhu hweruva rehermaphrodite hunosiyana zvichienderana nerudzi, asi kazhinji, zvinotevera ndizvo zvinonyanya kuzivikanwa:
- Mitezo miviri yekubereka: Ruva rehermaphrodite rine zvose stamens (nhengo dzechirume) uye pistils (nhengo dzechikadzi) mumunhu mumwe chete. Izvi zvinokutendera kuti uzviise fetiraiza.
- Kugona kuzviitisa: Imwe yemhando huru yeruva rehermaphrodite kugona kwayo kuzvisimudzira uye kugadzira mhodzi pasina kudiwa kwekumeserwa nemamwe maruva.
- Simba nekuchengetedza zviwanikwa: Nekusada kugadzirwa kwemwero wemukume kana kutsvaga mashamwari ekume, ruva rehermaphrodite rinochengetedza simba uye zviwanikwa.
- Variable morphology: Iyo morphology yeruva rehermaphrodite inogona kusiyana zvichienderana nerudzi. Zvisinei, kazhinji anotaridzika zvakafanana nemamwe maruva emhando imwe chete.
- Kugadzirisa kune dzakaipa mamiriro: Mazhinji hermaphroditic plant marudzi akajairana nemamiriro ezvinhu akashata, sekushaikwa kwemapollen partners kana kushomeka kwezviwanikwa. Nokudaro vanovimbisa kugadzirwa kwembeu uye kurarama kwemarudzi.
Zvakakosha kuziva kuti kuvapo kweruva re hermaphrodite hakuvimbisi kuti richazviberekesa, sezvo mamwe marudzi angada kukurudzirwa kubva kunze kuti abudise mukume. Uyezve, kuvapo kwenhengo dzekubereka dzechirume nedzechikadzi muruva rimwe chete hazvirevi kuti chirimwa chose i hermaphrodite. Mhando dzakawanda dzine maruva echirume neechikadzi pamiti yakasiyana.
Hermaphrodite Ruva: Mienzaniso
Hapana huwandu chaihwo hwemarudzi emaruva anotumbuka sehermaphroditic, sezvo iri boka guru rezvisikwa rinosanganisira marudzi akasiyana-siyana emiti. Zvinofungidzirwa kuti kune zviuru zvemarudzi emiti inotumbuka sehermaphroditic, kusanganisira miti, makwenzi, miriwo, uye cacti. Kuvapo kwemaruva anotumbuka sehermaphroditic kwakakosha pakuchinja kwemarudzi mazhinji emiti, sezvo zvichiita kuti ive nechokwadi chekuburitswa kwembeu uye kurarama kwemarudzi acho kunyangwe pasina mamwe marudzi ari pedyo ekusanganisa mukume.
Zvakakosha kuziva kuti haasi marudzi ese emiti ane hermaphroditic , uye kuti marudzi mazhinji ane maruva echirume neechikadzi pamarudzi akasiyana. Asi ngatitaurei nezvezvinotifadza: mienzaniso yakakurumbira yemaruva ane hermaphroditic.
chirimwa chematomatisi
Madomasi chirimwa che hermaphroditic chinobereka maruva madiki ane stamens ne pistils pamunhu mumwe chete. Maruva aya akakosha pakugadzira michero yematomatisi, sezvo ari iwo anokonzera kubereka uye kubereka mbeu. Ane girini rakachenuruka uye ane chimiro chetubhu. Stamens dziri pakati peruva uye dzine anther dzine mukume. Kune rumwe rutivi, mapistils ari pamusoro peruva uye ane stigma inounganidza mukume kubva kuma stamens.
Kuti ruva remadomasi ribereke, mukume unofanira kutamiswa kubva mudumbu kuenda kuhunhu hwechisikigo. Maitiro aya anogona kuitwa kuburikidza nekudhonza zvipembenene kana mhepo, kana kuburikidza nekudhonza zvirimwa nemaoko. Mushure mekudhonza, ruva remadomasi rinokura kuita muchero wedomasi uye rinotanga kukura kusvika pakukura kwaro. Kuvapo kwemaruva ehermaphrodite kwakakosha pakugadzira madomasi, uye varimi vanoshanda kuti vave nemaruva akakwana muzvirimwa zvavo.
chirimwa chenhanga
Mumwe muriwo unowanzo shandiswa muminda imanhanga, ayo anewo maruva ehermaphroditic. Aya anowanzo kuve makuru uye anoyevedza, ane stamens nepistils pamuti mumwe chete. Ane yero yakajeka uye akaita sebhero. Stamens dziri pakati peruva uye dzine anthers dzine mukume. Kune rumwe rutivi, pistils dziri pamusoro peruva uye dzine stigma inounganidza mukume kubva mumuti.
Kungofanana nematomatisi, mukume unofanirwa kutamiswa kubva mudumbu kuenda kune stigma kuti ruva remanhanga rive negoho. Izvi zvinoda kuunganidzwa kwemukume nemhepo, zvipembenene, kana nemaoko nevarimi. Mushure mekuunganidzwa kwemukume, ruva remanhanga rinokura kuita muchero uye rinotanga kukura kusvika pahukuru hwaro hwakazara.
Zvakakosha kuziva kuti mamwe marudzi emanhanga haawirirane, zvichireva kuti anofanira kusvinwa nemaruva emhando yakasiyana kuti abereke michero. Nekuda kweizvi, varimi vanowanzo rima marudzi akasiyana emanhanga mubindu rimwe chete kuti vave nechokwadi chekuti vanowana goho rakakwana remichero.
ruva
Maruva emaruva anodyarwa mumunda anonyanya kufarirwa nekuda kwekunaka kwawo nekunhuhwirira kwawo. Anoshandiswawo kugadzira mhando dzakasiyana-siyana dzezvirimwa. Maruva awo, ayo ari hermaphroditic, makuru uye anoyevedza. Ane chimiro chakanaka, chakaita sebhero chine mavara akasiyana-siyana, kubva pachena kusvika kutsvuku. Maruva aya ari pakati peruva uye ane maanther ane mukume. Mapistil ari pamusoro peruva uye ane stigma inounganidza mukume kubva kumakutu.
Kubereka mbeu kunoitwa nezvipembenene zvakaita senyuchi nemashavishavi, zvinodya nekita yemaruva uye zvinotakura mukume kubva kune rimwe ruva kuenda kune rimwe. Maitiro aya akakosha pakugadzira mbeu uye kukura kwemaruva matsva.
Maruva emaruva anosiyana-siyana uye anogona kurimwa munzvimbo dzakasiyana dzemamiriro ekunze nevhu. Kune mhando dzakasiyana dzemaruva, rimwe nerimwe rine hunhu hwaro nemavara aro. Uyezve, maruva emaruva anogona kushandiswa pakushongedza, kuronga maruva, uye kugadzira zvinonhuwira nezvizoro.
A orchid
Pakupedzisira, tine maorchid ekuratidza . Aya iboka rakasiyana-siyana rezvirimwa zve hermaphroditic zvinobereka maruva akasiyana-siyana uye anoyevedza ane stamens nepistils pamunhu mumwe chete. Zvirimwa izvi chirimwa chinozivikanwa mukurima uye chinoshandiswa kugadzira zvigadzirwa zvakasiyana-siyana. Zvine maruva e hermaphroditic anogona kuva ega kana kuunganidzwa mumapoka e racemes. Maruva aya ane chimiro chakaoma chinosanganisira stamens nepistils.
Orchid stamens akareba uye ari pakati peruva, nepo pistils ipfupi uye iri pamusoro peruva. Kukumeswa kwezvirimwa izvi kunoitwa nezvipembenene. Vanodya muto uye vanotakura mukume kubva pane rimwe ruva kuenda kune rimwe.
Maokidhi anowanikwa munzvimbo dzinopisa uye dziri pasi pevhu pasi rose, uye kune marudzi nemarudzi akasiyana anopfuura 20,000. Rudzi rwemaokidhi rumwe nerumwe rune maruva akasiyana ane maumbirwo nemavara chaiwo, kubva pachena kusvika kutsvuku, uye anosanganisira mavara akasiyana-siyana eyero, pink, uye purple.
Kunze kwekunaka kwawo, maoriki anokosha kumaindasitiri ekuzora nemafuta anonhuhwirira, sezvo maruva awo achishandiswa kugadzira zvinhu zvakaita semafuta anonhuhwirira, mafuta anonhuhwirira, uye mafuta anonhuhwirira. Anozivikanwawo semiti yemumba uye anorimwa pasi rese nekuda kwekunaka kwawo nekunhuhwirira kwawo.
Muchidimbu, hermaphroditic maruva akakosha pakurarama kwemhando dzezvirimwa zvine hunhu uhu uye anogona kuve mukana mumamiriro ezvinhu akashata, semamiriro ekunze akaoma kana nharaunda ine mapollinator mashoma. Mukuwedzera, ivo vanobatsira zvikuru kuvarimi.
