Asymmetric, zygomorphic thiab actinomorphic paj: ib nyuag piav qhia

Ib lub paj yog ib tug shortened tua ntawm ib tug nroj tsuag nrog hloov hloov nplooj. Qhov no yog feem ntau yog rau kev luam. Qhov zoo ntawm cov paj ntawm nroj tsuag yuav txawv heev.

Cov hom loj ntawm corollas

Txhua tus neeg uas muaj kev zoo nkauj tuaj yeem faib tau ua peb pawg loj:

• Nrog rau xim xim kabmob;
• Nrog asymmetric;
• Nrog asymmetric.

Tag nrho cov ntau yam yog sawv cev los ntawm ib tug lossis loj tus naj npawb ntawm cov nroj tsuag ntawm ntau genera thiab cov tsev neeg. Hom paj, los ntawm txoj kev, yog qhov tseem ceeb rau qhov kev txiav txim siab raug cai.

Symmetrical corollas

Thawj hom paj hauv biology hu ua actinomorphic. Tag nrho cov seem ntawm lub coronas nyob rau hauv xws li nroj tsuag yog tiag symmetrical. Actinomorphic paj yog feem ntau ntawm qhov tseeb tias tsis muaj tsawg tshaj ob lub dav hlau yuav tsum kos los ntawm nws cov axis. Saib zoo li cov nroj tsuag, ntawm chav kawm, heev txaus nyiam. Txawm li cas los xij, nws ntseeg tau tias rau cov pollination los ntawm cov kab lawv tsis zoo yoog.

Ntau hom duab ntawm cov kab mob symmetrical

Qhov tseeb paj actinomorphic, ntawm lwm yam, muaj peev xwm muaj ib tug txawv tus naj npawb ntawm petals. Qee lub sij hawm lawv muaj txheej txheem nyob rau hauv ib kab, qee zaum hauv ntau. Ua tau, tus actinomorphic corollas txawv hauv cov nta xws li:

• Qhov ntev ntawm raj;
• Daim ntawv ntawm txoj hlua khi;
• Tus nqi ntawm dabtsi yog khoov.

Actinomorphic paj yuav ua tau:

1. Log-puab. Lub raj ntawm cov coronals yog me me los yog suab tsis tuaj kawm ntawv. Cov khoov yog muab faib rau hauv tib lub dav hlau.
2. Funnel-puab. Xws li cov paj no muaj raj loj heev. Lub curvature ntawm lub corolla yog me me.
3. Tubular. Lub corollas ntawm cov pab pawg no yog cov ua cim los ntawm ib lub cylindrical tube thiab txoj kev luv luv ntawm txoj hlua.
4. Campanulate. Xws li tus paj yeeb cov paj yeeb tau muaj ib lub khob zoo li lub raj kheej, maj mam tig mus rau hauv qhov khoov qes-pom.
5. Kolpachkovym. Nyob rau hauv xws li paj nplua nuj loj hlob ua ke nrog lub tswv yim.

Unsymmetrical paj

Cov nroj tsuag nrog coronals ntawm no ntau yam muaj nyob rau hauv qhov zoo heev feem ntau. Biologists hu rau cov paj zygomorphic. Los ntawm qhov chaw ntawm tus kabmob asymmetrical corolla, koj tuaj yeem kos ib qho dav hlau xwb.

Hom zygomorphic paj

Corollas ntawm pab pawg no muaj ib daim ntawv tshwj xeeb, uas feem ntau yog hom kab mob ntawm hom tsiaj (thiab qee zaus txawm ntawm tsev neeg). Cov phom lawv muaj feem ntau fused. Nyob rau hauv qhov muaj zygomorphic paj:

1. Bilabiate. Nyob rau hauv xws li ntawm cov ces kaum, cov khoov nws muaj cov ncauj thiab sab hauv qab.
2. Reed. Los ntawm lub raj ntawm corollas, fused petals tawm.
3. Shporistye. Cov nplais ntawm xws li paj tsim ib tag outgrowth, uas yog hu ua ib tug spur.

Asymmetric paj

Dab tsi yog actinomorphic thiab zygomorphic paj, peb pom tawm. Asymmetric fab yog cov ua cim, ua ntej ntawm tag nrho cov, los ntawm qhov tseeb tias tsis muaj dav hlau symmetry tau kos los ntawm lawv qhov chaw. Muaj cov nroj tsuag zoo li cov tsiaj qus tsis ntau zaus. Feem coob ntawm cov kabmob ornamental tseem muaj cov kabmob lossis cov kabmob asymmetric.

Piv txwv ntawm actinomorphic xim

Qhov tseeb hais tias cov kab mob symmetrical tsis yog pollinated los ntawm kab, raws li biologists, yog ib qho ntawm lawv lub koom haum tsawg. Tab sis qhov twg, nyob rau hauv qhov, feem ntau muaj cov nroj tsuag nrog actinomorphic paj. Rau pawg no muaj tag nrho cov paub zoo me ntsis, teb thiab hav zoov paj, xws li:

• Tsis nco qab-kuv-luss (log-puab);
• Kev dag ntxias, haus luam yeeb (funnel-puab);
• Paj ntawm tsev neeg Astro (tubular);
• Lilies ntawm lub hav (campanulate);
• Wild grapes (cap).

Nyob rau hauv lub vaj, feem ntau ntawm ornamental herbaceous thiab shrubby kab lis kev cai kuj muaj symmetrical coronas. Actinomorphic paj muaj, piv txwv li, peonies, daffodils, sunflowers, lilies, mallow.

Ntawm shrubby haiv neeg, tib pab pawg neeg muaj xws li tus aub rose, lilac, spirea. Actinomorphic yog paj ntawm vaj txiv hmab.

Piv txwv ntawm cov nroj tsuag nrog zygomorphic coronals

Peb pom tawm uas cov nroj tsuag muaj txoj cai paj, actinomorphic paj. Cov pab pawg hauv qhov yog qhov ntau tshaj. Zygomorphic nroj tsuag nyob rau tom teb thiab hauv hav zoov yog ntsib nrog me ntsis tsawg dua. Piv txwv ntawm cov qoob loo xws li:

• Ob-horned norichnikovye;
• Reed dandelion;
• Spurgeous linen thiab watershed.

Cov khoom zoo nkauj ntawm cov paj ntawm pawg neeg no feem ntau yog tsis siab dhau. Yog li ntawd, mus decorate txojkev thiab cov mev, thiab raws li kom compose bouquets, lawv tau hlob heev tsis tshua muaj. Tab sis qee zaus koj tuaj yeem pom tej paj hauv vaj thiab paj txaj, tau kawg. Piv txwv li, ib tug zoo dai kom zoo ntawm lub site yuav ua tau ib tug vyazel (vaj teb nas taum). Cov kab lis kev cai no feem ntau siv hauv kev tsim kom zoo nkauj hauv av ua av npog.

Piv txwv ntawm cov xim asymmetric

Cov nroj tsuag ntawm pawg no, raws li twb tau hais, ob qho tib si nyob rau hauv qhov thiab nyob rau hauv teb yog tsawg. Lawv cov coronets zoo nkauj zoo nraug thiab txawv txav, thiab yog li ntawd yuav siv tau nyob rau hauv kev tsim kom zoo nkauj toj roob hauv pes. Cov neeg sawv cev ntawm ib pawg ntawm ib pawg ntawm cov nroj tsuag nrog asymmetric xim yog, piv txwv li, zoo-paub rau tag nrho cov cannes. Tsis tas li ntawd, nyob rau hauv kev kos duab kos, feem ntau yog siv chestnut.

Ntawm cov hoob kawm, cov nroj tsuag ntawm no pab pawg neeg kuj muaj peev xwm pom nyob rau hauv cov qus. Asymmetric paj, piv txwv li, muaj ib tug nroj tsuag medicinal valerian.
