Reproduction vegetative. He aha te mea te tikanga? Te tikanga micropropagation

Reproduction Ko tetahi o nga āhuatanga o kaiao ora katoa, me manawa, kai tōtika, kaupapa me ētahi atu. He uaua ki te pe si◊aki tikanga reira, no te mea whakarite reira te tonu o whakatupuranga, a konei te oraraa rawa o te ora i runga i te ao whenua.

I roto i te natura kawea ingoa tukanga i roto i ngā huarahi. Ko tētahi o ratou - tōkai reproduction vegetative. Kei te kitea te reira i te nuinga i roto i ngā tipu. Ka te uara o te whakatö vegetative me ona rerekē e kōrero i roto i to tatou whakaputanga.

He aha te mea whakaputa uri tōtahi

koiora High-kura whakatau uri vegetative o ngā tipu (Grade 6, wāhanga "Botany") rite te momo o tōkai. tikanga o tēnei e i roto i te akoranga o tona whakatinanatanga kore e whai wāhi pūtau iroriki. Na, i runga i, e kore te mea e taea te tauhono o te mōhiohio ā-ira.

Ko reira te tikanga tawhito te nuinga o te uri, āhuatanga o te tipu, harore, huakita, me etahi kararehe. takoto Ko tōna ngako i roto i te hanganga o āpiti o te momo matua.

I tua atu ki te vegetative, i reira e te tahi atu huarahi o whakaputa uri tōtahi. Ko te tahito tino o enei ko te wehenga ki ngā pūtau e rua. Na tini kararehe pūtau-tahi me ngā tipu me te huakita.

Ko tētahi atu putanga o tenei tikanga ko te wehenga maha. Kei te wā kotahi te reira i hanga e rave rahi āpiti o te pūtau matua taua. tupu tenei, hei tauira, Plasmodium falciparum, i te mea pirinoa i roto i te pūtau toto.

He puka motuhake o te whakaputa uri tōtahi ko te hanganga o pua. Horsetails, te kaponga, Kiwa me Kiwa karapu tā taua ara.

uri vegetative tōkai

E mea pinepine, ka tōkai uri whakawhanake te rauropi hou i te rōpū katoa o ngā pūtau matua. ka karanga tenei ahua o te whakaputa uri tōtahi te vegetative.

Next, whakaahua tatou nga momo me tauira o kaiao e kua āhuatanga e whakatö vegetative. Ko te tepu ngā ratou, ka whiwhi i te whakaaro whānui o te nuinga o tenei momo o te uri.

Reproduction o ngā wāhanga o whekau vegetative

okana tipu vegetative ko te morehu, arā o kakau me rau, me te pakiaka - okana raro. Wāwāhi atu wahi o to ratou multicellular whaia taea te tangata te kawe i roto i cloning ranei.

He aha te mea te haea hei tauira? Ko reira he ara o mea whakatö vegetative horihori. Na, ki te whakapiki ake i te maha o rakau vine e, me te kuihi, e hiahia ana koe ki te tango i tetahi wahi o to ratou pūnaha pakiaka ki te whatukuhu, o nei te mutunga faaho'ihia mai mawhiti.

Ko hoki karepe tupuranga tano petioles kakau. O ratou ki etahi wa ora te pūnaha pakiaka o te tipu. Ko te titauhia Ko te wātea o te ahua tetahi o tākihi i roto i te kakau.

Ko mo te whakaputa uri o maha tipu roto maha whakamahi i te rau. Pono, he maha violets tikanga diluted.

wana Reproduction whakarerekētia

He maha ngā tipu hanga nga whekau vegetative o akatuke'anga e tukua ki a ratou mahi mahi atu. Ko tētahi o ēnei mahi - vegetative whakatö. He aha te mea he whakarereke motuhake o te wana, i matau ai tatou ki te whakaaro tatou motuhake nga pakiaka, topuku me ngā kōpura.

māngaro

Kei tēnei wāhanga o te tipu kei te raro, me te rite te pakiaka, engari, ahakoa te ingoa, ko te whakarerekē o te mawhiti. Kei a ia ko internodes elongated, e whakarere ana i te pakiaka adventitious me rau.

Tauira o ngā tipu e whakaputa uri i te tikanga o rhizomes, ko te rengarenga o te raorao, iris, te miniti. I te tahi taime i huaina taea te kitea i te tinana i roto i te taru. Te tangata e matau pehea uaua ko reira ki te pehea e moenga tarutaru. Toia te reira i roto i o te whenua, ahu iwi ki te waiho wāhanga o te pakiaka tuhituhia o wheatgrass raro. A muri iho i te tetahi wa, pariri ano ratou. Na reira, ki te pehea e o te tarutaru i huaina, ko reira e tika ana ki te āta keri ake.

umanga

Riki, te kāriki, Nakihu me te whakaputa uri te whakamahi i akatuke'anga podezmnyh wana, ka karanga topuku. Ratou kakau flat huaina Donets. I he reira reka rau kikokiko he matūkai penapena, me te tākihi. hoatu ratou ara ki kaiao hou. Umanga taea te whakato ki te ora i raro i te whenua uaua mo te wa tupuranga - tauraki matao ranei.

Kōpura me te ngutu

Hei tārua kore e hiahia ana i te rīwai ki te rui i nga purapura, ahakoa te meka e hanga reira puawai me hua. Tenei tipu whakamahi i whakarerekētanga raro wana - kōpura. Hei tohaina rīwai, e kore noa tino i taua te kōpura katoa. Kati te Kongakonga reira kei roto i te puku e ka tupu raro, whakaora i te tipu katoa.

He rōpere me rōpere i muri i puawai me te fruiting puka he whiu whenua (pāhau), e he wana hou. Ratau, e kore e taea e ratou e raruraru ki te hirihiri o karepe, hei tauira. Tenei whakatokia mahi ratou i te mahi rerekē - te kaha ki te riro i te tunga i runga i te tautoko mō te tūranga ake māhorahora i roto i te pā ana ki te ra.

wehewehenga

E kore e taea e tipu anake te tā i te tikanga o te wehe ona wahi maha-pūtau. Kei te kitea hoki tenei āhuatanga i roto i nga kararehe. Tākongakongatanga rite te reproduction vegetative - he aha te mea te reira? hāngai ana tēnei tukanga i runga i te kaha o kaiao ki te whakaora - whakaora o ngā wāhanga tinana ngaro pakaru ranei. Hei tauira, te tinana o te noke e taea te whakahoki mai i te takitahi katoa, tae atu ki ngā pukupuku, me whekau o te kararehe.

gemmation

He kotiti tetahi tikanga o te uri, engari vegetative puku ki reira - hua. Ko tōna ngako ko e whai ake: i runga i hanga te tinana o te kaiao matua te protrusion, tupu te reira, e te reira i runga i te āhuatanga o te kaiao pakeke me te piri i te oraraa motuhake.

he tukanga taua o te hua puta i roto i te wai māori hydra. Ko ētahi atu māngai o coelenterates - rupi - e kore te protrusion i hanga piri a mau tonu i roto i te tinana o te whaea. Ka rite ki te hua, ākau i hanga āhua rerehua.

Te whakanui ake i te nui o pōhā, i te mea rite ki te awhina o rewena, i te ara, he ana hoki he hua o to ratou uri vegetative mā te hua.

Te tikanga micropropagation

Ka rite ki a koutou e taea te kite, te whakaputa uri vegetative i roto i te natura e horahia whānuitia nui. arata'i i tēnei aratuka ki te hua tere i roto i te maha o te mau taata o te ngā momo. Ko te otaota hoki tenei, ara he tokomaha o ngā pūrere, i roto i te puka o whakarerekētanga ki te pakiaka me te manga.

Mā te whakatö vegetative horihori (e titau mai kī mua he ariā taua), e whakamahatia tetahi otaota, e whakamahi ana i roto i ona ngā mahi pakihi. Aita e titauhia ia takitahi o te takoto te ritenga. Hoki pihi o ngā tipu taitamariki te whanaketanga o ngā momo hou taiao rawa waia i roto i nei ora te tinana o te whaea ranei.

Heoi, momo katoa o te whakaputa uri tōtahi, tae atu i te vegetative, i reira he kotahi āhuatanga. Ko tōna hua ko te putanga o rauropi ira ōrite e te hunga i te kape tangohia o te matua. Hei whakaora i te momo, me ngā āhuatanga ira o he pai tenei tikanga o te uri. Otiia ki te rerekētanga katoa he nui atu uaua.

Ko whakaputa uri tōtahi te tikanga whakaputa i te tinana o te ahua taea o pūāhua hou, a ko te kupu i te ara ki te urutau ki te huri ngā āhuatanga taiao. Na reira, e taea ki te whai wāhi i roto i te tukanga fakasekisualé te nuinga o nga momo i roto i te mohoao me.

Ahakoa tenei drawback, ka hua ngakia tipu tino faufaa, me te whakamahia whānuitia ko tonu whakatö vegetative. Ko te tangata hari ki tenei tikanga no te mea o te whānui o ngā whai wāhitanga, iti i roto i ngā o te roanga momo, me te maha o ngā rauropi e whakaputa uri te tikanga whakaahuatia.
