Qhov sib txawv tseem ceeb ntawm racemose thiab cymose inflorescence yog tias racemose inflorescence yog ib hom inflorescence uas lub ntsiab axis muaj kev loj hlob tsis tu ncua thiab paj yog tam sim no tom qab, thaum cymose inflorescence yog ib hom inflorescence uas lub ntsiab axis muaj kev loj hlob tsawg. thiab paj yog tam sim no terminally.

Inflorescence yog hom paj npaj hauv cov paj ntoo. Nws muaj ib pawg ntawm paj teem rau ntawm qia los yog paj axis. Muaj ob hom inflorescence raws li kev loj hlob ntawm floral axis. Lawv yog racemose thiab cymose inflorescence. Nyob rau hauv racemose inflorescence, lub paj yog teem tom qab nyob rau hauv ib tug acropetal yam, thiab lub ntsiab axis los yog qia tseem loj hlob indefinitely. Nyob rau hauv cymose inflorescence, lub ntsiab axis los yog qia txiav mus rau hauv ib lub paj thiab yog li ntawd muaj ib tug txwv kev loj hlob los yog txiav txim loj hlob. Tsis tas li ntawd, muaj ntau ntau hom inflorescences xws li compound inflorescence, cyathium, hypanthodium, thiab verticillaster.

Racemose Inflorescence yog dab tsi?

Racemose inflorescence yog hom inflorescence uas lub ntsiab axis muaj kev loj hlob tsis txwv. Racemose inflorescence muaj ib lub peduncle ua lub ntsiab axis, thiab qhov no tseem ua rau lub paj tawg. Txawm li cas los xij, lub peduncle tsis tshua muaj terminates hauv paj. Nws yog monopodial, piv txwv li, nws muaj ib lub ntsiab qia uas tsim nplooj thiab paj. Thawj paj uas tau tsim nyob rau hauv lub hauv paus ntawm peduncle thiab yug tom qab nyob rau hauv ib qho kev npaj acropetal. Feem ntau, cov paj hluas npaj nyob rau hauv lub taub los yog nruab nrab, thiab cov paj laus yog nyob rau ntawm lub periphery los yog ntawm lub hauv paus.

Daim duab 01: Racemose Inflorescence

Racemose inflorescence faib ua ntau hom xws li raceme, spike, spikelets, catkin, spadix, corymb, umbel, thiab capitulum raws li branching, peduncle ntev, thiab muaj lossis tsis muaj pedicel. Raceme, spikes, spikelets, catkin, thiab spadix muaj lub ntsiab elongated. Corymb thiab umbel muaj lub ntsiab axis luv. Lub capitulum muaj ib tug flattened lub ntsiab axis. Raceme muaj lub ntsiab axis uas yog unbranched thiab elongated thiab dais pedicellate paj nyob rau hauv ib qho kev npaj acropetal. Lub ntsiab axis ntawm spike kuj yog unbranched nrog unlimited kev loj hlob, tab sis paj yog sessile. Spikelets yog cov sib xyaw spikes, thiab lawv yog branched nrog sessile paj. Catkin yog ib qho kev hloov kho ntawm ib tug spike nrog ib tug drooping central qia thiab muaj sessile paj uas yog unisexual. Spadix kuj yog ib qho kev hloov kho ntawm ib tug spike nrog ib tug fleshy axis thiab muaj ib tug xov tooj ntawm sessile paj. Corymb muaj cov ceg ntoo loj thiab muaj cov paj pedicellate. Txhua ceg muaj paj nyob rau hauv corymbs. Umbel muaj ib tug whorl, thiab paj tshwm sim los ntawm axil ntawm bracts. Capitulum hu ua racemose taub hau. Nws yog lub siab tshaj plaws inflorescence. Lub peduncle yog luv thiab dav, thiab cov paj yog hu ua florets.

Cymose Inflorescence yog dab tsi?

Cymose inflorescence yog hom inflorescence uas muaj lub paj ntawm lub apex ntawm paj axis. Qhov no inflorescence muaj ib sab axis uas xaus rau hauv paj thiab txwv txoj kev loj hlob ntawm axis. Cov paj tam sim no nyob rau hauv basipetal kev npaj; Cov paj hluas yog nyob rau ntawm lub hauv paus, thiab cov paj loj yog nyob rau hauv lub ntsis los yog nruab nrab.

Daim duab 02: Cymose Inflorescence

Muaj plaub yam tseem ceeb ntawm cymose inflorescence: monochasial cyme, dichasial cyme, polychasial cyme, thiab cymose capitulum. Monochasial cyme tseem hu ua uniparous cyme, thiab nws lub ntsiab axis xaus rau hauv paj. Qhov no kuj tsim ib tug lateral ceg los ntawm lub hauv paus nrog ib tug davhlau ya nyob twg paj. Monochasial cyme tau muab faib ua ob hom: scorpioid thiab helicoid. Dichasial cyme tseem hu ua biparous cyme, thiab lub davhlau ya nyob twg peduncle xaus rau hauv lub paj. Qhov no ua rau muaj kev nce rau ob sab ceg nrog cov paj paj. Polychasial cyme yog hu ua multiparous cyme thiab muaj ntau ceg uas tshwm sim ntawm lub hauv paus ntawm apical paj ntawm peduncle. Lub peduncle txo mus rau ib ncig disc. Ntawm no, cov paj loj hlob nyob rau hauv qhov chaw thaum cov paj hluas hlob nyob rau hauv periphery.

Dab tsi zoo sib xws ntawm Racemose thiab Cymose Inflorescence?

  • Racemose thiab cymose inflorescence yog hom kev npaj paj.
  • ob leeg yog cov paj yooj yim.
  • Ob leeg muaj ntau tus florets teem rau hauv ib qho peduncle.
  • Txoj kev sib txuas ntawm floret rau peduncle tshwm sim los ntawm pedicel hauv ob hom.
  • Lub luag haujlwm tseem ceeb ntawm ob qho tib si yog txhawm rau txhim kho cov kab paj ntoo.

Qhov txawv ntawm Racemose thiab Cymose Inflorescence yog dab tsi?

Nyob rau hauv racemose inflorescence, paj yog teem rau tom qab, thaum nyob rau hauv ib tug cymose inflorescence, cov paj yog teem nyob rau hauv lub floral axis. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm racemose thiab cymose inflorescence. Tsis tas li ntawd, racemose inflorescence qhia tau hais tias kev loj hlob tsis tu ncua nyob rau hauv lub ntsiab paj axis, tab sis cymose inflorescence qhia tau hais tias kev loj hlob tsawg nyob rau hauv lub ntsiab paj axis. Ntxiv mus, lub peduncle nyob rau hauv racemose inflorescence qhia ib tug monopodial kev loj hlob, thaum nyob rau hauv ib tug cymose inflorescence, lub peduncle qhia ib tug sympodial los yog multipodial kev loj hlob.

Cov hauv qab no qhia txog qhov sib txawv ntawm racemose thiab cymose inflorescence hauv daim ntawv tabular rau ib sab ntawm kev sib piv.

Summary – Racemose vs Cymose Inflorescence

Lub paj yog ob hom raws li kev loj hlob ntawm apex. Lawv yog racemose thiab cymose. Nyob rau hauv racemose inflorescence, paj yog teem tom qab, thaum nyob rau hauv ib tug cymose inflorescence, paj yog teem nyob rau hauv lub floral axis. Lub ntsiab axis ntawm racemose inflorescence muaj unlimited kev loj hlob. Nws muaj ib tug peduncle raws li lub ntsiab axis, thiab qhov no tseem tsim ib lub paj buds. Cymose inflorescence muaj ib lub paj ntawm apex ntawm paj axis. Lub ntsiab axis ntawm cymose inflorescence muaj kev loj hlob tsawg. Yog li, qhov no qhia txog qhov sib txawv ntawm racemose thiab cymose inflorescence.
